Personnel

A number of personnel changes occurred in the project during the past year.  C.T. decided to retire and finished 23 years of dedicated service to the University of Idaho and Idaho grain producers on June 30, 1999.  A special thank you is extended to C.T. for the leadership he gave and for successfully guiding the BEP project during the first seven years of its existence.  Ying Wu accepted a position with Stephen Guy’s program in Moscow and left the project at the end of June 1999.  Ying had coordinated the southern Idaho portion of the project since 1992. 

Larry Robertson was asked to provide program leadership beginning in the spring of 1999.  This is in addition to his Extension program already in place.  Kenny Pulliam became a full time Technical Aide in July 1999 and will be helping with the cereal Extension program as well as the BEP program. David Bergey was hired as a Scientific Aide to replace Ying in southern Idaho and started work on November 5, 1999.  David comes from the Challis area and has solid science background in mine reclamation. 

Karen Dempster is the lone continuous employee in the BEP program.  Karen has coordinated the northern Idaho part of the BEP program since 1992.  Her knowledge and enthusiastic work ethic are much appreciated. 

ACKNOWLEDGMENTS

The 1998-99 growing season was the eighth year for the Idaho Barley Enhancement Program (BEP).  The program planted 5828 replicated yield plots and 4,789 unreplicated breeding plots.  Trials were grown in 12 different locations, three of which were irrigated (Parma, Kimberly, and Aberdeen).  Some trial locations were provided by local farmer-cooperators.  Appreciation is given to them for their help and cooperation. Appreciation is also extended to cooperating UI personnel including numerous county educators.  Test locations and cooperators for 1999 are listed below:

A special thanks goes to Darrell Wesenberg (USDA-ARS, Aberdeen), who provided the bulk of the test materials and for his continuous advice and encouragement throughout the year.  Thanks are also given to An Hang and Phil Bregitzer (USDA-ARS, Aberdeen) for trial materials, and to Stephen Guy (UI Moscow) and Brad Brown (UI Parma) for their help and cooperation in getting trials planted, cared for, and harvested.  Many others contributed to the project.  Appreciation is extended to all who helped, directly or indirectly, during the past season. 

Most of all, appreciation is given to Idaho barley producers.  Check-off dollars administered through the Idaho Barley Commission and strong support and encouragement by IBC commissioners and staff are essential for the success of this program.  Without this support, the program would not exist.  Materials included in these trials originated from many breeding programs.  Appreciation is given to the many individuals both public and private that contributed to the program. 

Camas (ND9147) is the first variety release from the BEP.  It is a 2-rowed spring barley that should compete favorably across much of the dryland environment in Idaho and adjoining states.  Limited foundation seed should be available in the spring of 2001.  The development and release of Camas has become a symbol of cooperation among the University of Idaho, USDA-ARS, public and private barley breeders, researchers, and the barley industry. 

List of data tables

Introduction

This report summarizes the results of the data collected by the BEP program during the 1998-99 growing season.  Three winter barley, 28 spring barley and two spring oat trials were established at 12 locations throughout Idaho during the fall of 1998 and spring of 1999. The trial planted at Potlatch was not harvested because of non-uniform weed pressure and soil fertility problems.  The Clarkston, UT, trial was established in an attempt to evaluate barley scald and stripe rust, which had been reported from this area in previous years.  The diseases failed to develop and no data were collected from this location.  Moscow, Parma, and Kimberly had winter barley trials.  The Moscow trial was not harvested because of extensive winterkill in the trial.  Spring trials were grown at all locations listed except Kimberly. Tetonia data, provided by Darrell Wesenberg, is included in the report to supplement the preliminary yield nursery results.  The elevation, average precipitation (ppt), and soil type at each location are listed below:

Test Procedures

Most of the trials were replicated four times and planted in a randomized block design, as 7 row plots with 7-inch row spacing, 15 feet long.  The non-replicated trials were planted in the same manner, with each entry being represented once.  The plots were cut back to make a 10- or 11-foot plot for harvest.  A seeding rate of approximately 80 pounds/acre was used.  All nurseries were established and maintained under grower management conditions except for Moscow, Parma, Kimberly, Aberdeen, and Tetonia which were located on University of Idaho Research and Extension Centers.  As far as possible, all cultural operations and fertilizer and chemical applications were the same as applied to the surrounding field and matched commercial management.  Timing of planting and harvest operations coincided with cooperator operations. 

Data Collection

Agronomic data, including yield, test weight, heading date, height, lodging, and percent plump were collected from all trials (heading date was not recorded at Fairfield).  Yield was calculated as bushels per acre using the standards of 48 pounds per bushel for barley and 32 pounds per bushel for oats.  Test weight was reported in pounds per standard bushel.    Heading date was recorded as the number of days after January 1 when 50 percent of the heads had emerged from the flag leaf sheath.  Plant height was reported in inches from the soil surface to the tip of the heads, awns excluded.  Lodging was reported on a scale of 1-9, 1 = erect and 9 = flat.  Percent plump was recorded as the percent of seed staying on top of a 6/64 screen after 25 cycles of shaking. 

Selected samples were sent to the USDA-ARS cereal lab in Wisconsin for malting quality analysis.  Selected samples of hulless barley were pearled and evaluated for suitability for export market.  Results of these evaluations were not available when this report was printed. 

Statistical Interpretation

Most tables have a least significant difference (LSD) statistic at the bottom of the table. These data are given at the 5 percent error level or the 10 percent error level and are an aid in comparing data among varieties.  If the reported values of any two varieties within a table differ by the LSD statistic or more, they may be considered different with a confidence level of 95 percent or 90 percent.  If the difference between reported values is less than the LSD value, the difference may be due to random error rather than a real difference between varieties.  Where data represents variety means across locations or years, an appropriation to a combined LSD was calculated.  The coefficient of variation (CV) is also included in some tables.  This is given as a general measurement of the precision of each experiment.  Lower CV values indicate less experimental variation and greater precision.  Planting and harvest dates of each nursery are stated at the bottom of the table as additional information. 

Western Winter Barley Nursery (WWBN)

The 1998-99 WWBN contained advanced generation lines and varieties from Idaho, Oregon, Washington, Nebraska, Oklahoma, Texas, Sunderman Breeding Inc., and USDA-ARS, Aberdeen.  The nursery of 50 entries was planted in Moscow on Sept. 24, 1998, Kimberly on Oct. 7, 1998, and in Parma on Oct. 6, 1998. 

  Moscow – trial not harvested due to extensive winter kill. 

Yields at Kimberly were lower than average due to dry soil during the winter and early spring prior to availability of irrigation water.  This early season plant stress was not overcome by later irrigation.  Plant height averaged 13 inches less in 1999 than a similar nursery in 1998.  Likewise, height was almost 10 inches shorter in 1999 than two other comparable irrigated locations that did not have drought stress.  Yield averaged 114.6 bu/acre with the highest yielding varieties being Schuyler and Sunstar Pride.  92Ab561, 96Ab69, and 88Ab124 were highest yielding experimental lines.  Test weight tended to be lower than average with the average being 46.9 lb/bu.  Highest test weights were from Kamiak (51.7 ) and Schuyler (50.6 ) and lowest from WA 2648-89 (42.1) and 88Ab977 (43.8).  Kamiak, Gwen, NE 90721, and ORW-10 were earliest varieties to head.  Sprinter and Puffin along with experimentals ORW-10 and ORW-11 had highest percent plump.  Data are in Table 1.

Parma recorded higher yields than in previous years with Sunstar Pride and OR FB81019 exceeding 200 bu/acre.  Puffin and Pipkin, both 2-rowed varieties, suffered severe loss from bird feeding and had yields of only 61 and 54 bu/acre.  All other varieties had yields of 120 bu/acre or more.  Test weights averaged 50.9 lb/bu and several varieties exceeded 53 lb/bu.  Lowest test weights were from Showin (47.3) and 97Ab536 (48.1).  Plant height averaged 36 inches tall with KB 941085 being tallest (44 inches) and 5 varieties were 31 inches tall or shorter.  Gwen and Kamiak were earliest to head and 97Ab11, KB 941085, and Sunstar Pride were latest.  Lodging averaged 5 for all varieties with a range of 1 to 9.  ORW-10, ORW-11, and 94Ab1818 had the highest percent plump at 96 or 97 percent and 97Ab505 was the lowest.  The average of all plumps was 72 percent.  Data are in Table 2.

Table 3 gives the combined data for the Kimberly and Parma trials.  Table 4 gives yield and test weight data over years for winter barley varieties.  For all varieties that have at least 4 years of testing, Sunstar Pride has the highest yield.

Western Dryland Spring Barley Nursery (WDSBN)

The WDSBN is a regional trial that is grown throughout the western spring barley region.  It is coordinated by USDA-ARS.  This trial contained 50 entries and was grown as part of the BEP trials at Soda Springs and Moscow.  The Soda Springs data are given in Table 5.  Bancroft and MT920073 were top yielding entries with 74 and 70 bu/acre.  Lowest yield was from ND16092.  Camas yield was 64 bu/acre, which compares favorably to Baronesse (69), Chinook (67), Hector (61), Harrington (58), and Steptoe (60).  Highest test weight from non-hulless types was 52.6 lb/bu (Chinook and Harrington), low test weights ranged down to about 47 lb/bu.  For a dryland trial, percent plump was high.  This reflects late season rainfall that helped with grainfill. 

Moscow data are in Table 6.  Grain yield for the entire trial averaged 111 bu/acre with highest yields over 130 bu/acre (93Ab688, UT005828, and Camas).  Low yields were in the mid-80’s.  Test weight averaged just over 47 lb/bu which reflects stress during grainfill.  High test weight entries included Camas, Crest, and 94Ab12990, and CDC Dolly.  Lowest test weights were from Harrington, Merit, and UT005708.  Plump seed percent averaged 68 percent but was variable as indicated by the high CV.  Five entries had plumps over 90 percent and the range was all the way down to 19 percent  for Harrington. 

Table 7 gives the combined data for Soda Springs and Moscow.  Camas and 93Ab688 (98 bu/acre), MT920073 (97 bu/acre), and UT004087 (96 bu/acre) recorded highest average yields.  Highest average test weight was BZ594-35 (55.9 lb/bu).  Munsing was the shortest entry (24 inches) and ND15477 was tallest (34 inches).  Table 8 gives yield and test weight data averaged over years tested.  MT920073, Camas, and Xena had highest yields for the 1998-99 period and Baronesse had the highest average when more than 10 station years of tests were included.  94Ab12271 had the highest test weight averaged over the past two years.

Western Spring Barley Nursery (WSBN)

The WSBN is a regional nursery that is grown throughout the western spring barley region.  It is coordinated by USDA-ARS.  This trial contained 50 entries and was grown as part of the BEP trials at Moscow and Bonners Ferry.  Entries in this trial represent the most advanced materials from breeding programs in surrounding states.  The nursery average at Moscow (Table 9) was 122 bu/acre with 92Ab5697 (147 bu/acre) having the highest yield and 10 additional entries over 130 bu/acre.  All entries exceeded 100 bu/acre.  Test weight was about average for spring barley with a range of 56+ lb/bu to less than 43 lb/bu.  Percent plump ranged from 96 percent (Orca) to a low of 41 percent for Colter and OR2967007.  Height ranged from 25 inches (Gustoe) to 44 inches for Morex.  Most varieties had lodging scores of 1 (scale 1-9, 1 = best) with a high score of 3. 

Table 10 gives data from Bonners Ferry.  Yield was again very good (average 125 bu/acre) with highest yields from 92Ab5697, WA9339-91, and Stander.  Lowest yield was recorded by Millennium (91 bu/acre).  Test weights were generally good with an average of 50.5 lb/bu and a high of 53+ ranging down to a low of less than 46 lb/bu.  Percent plump seed averaged 85 percent and ranged from 98 percent (Orca) down to 54 percent for Millennium.  Many varieties had lodging scores of 2 or 3 (scale 1-9, 1 = best) with a low of 1 and a high of 4 (Morex). 

Combined data for this trial are in Table 11.  Table 12 gives yield and test weight data averaged over years.  92Ab5697, WA9504-94, and WA9339-91 had highest yields over the 1998-99 period and WA 9339-91 had the top yield over the period 1995-99. 

Advanced Yield Nursery (AYN)

The AYN had 70 entries primarily composed of advanced lines from the Aberdeen breeding project.  The trial was grown at two locations in southern Idaho and four locations in northern Idaho. Table 13 gives data from Fairfield, a dryland location.  Little precipitation fell on the area during the growing season and yield was low.  Soil variability in the trial area resulted in high CV values for yield and plant height.  Highest yields were from Colter (44 bu/acre) and 91Ab1348 (41bu/acare).  Lowest yields were 25 bu/acre. Test weights were relatively good considering the lack of growing season precipitation.  Percent plump was down to 68 percent for the nursery average and ranged from a high of 88 percent (Orca and 86Ab1527) to a low of 35 percent for Millennium.  Many entries were very short with CDC Dolly only 13 inches tall and a number of other entries in the 14-15 inch range.  The tallest height recorded was only 21 inches (95Ab11469). 

Parma data is given in Table 14.  Conditions for the Parma trial were generally very favorable and the trial developed well.  High lodging scores were a result of high yields.  Nursery average yield was 131 bu/acre and ranged from 156 (Millennium) to 77 for Morex.  Other entries with high yields included Tankard (152 ), He6291 (154 ), UT005645 (150), and UT005724 (150).  Test weight was very high, averaging 53.6 lb/bu for the entire trial.  Baronesse, CDC Dolly, and Moravian 14 were all above 55 lb/bu.  Lowest test weight was 51.6 (Tango) and 51.8 (UT005724).  Percent plump seed was also very good with overall average 85 percent and a range from 98 to 83 percent.  UT005645, Millennium, and Foster were earliest to head.  Plant height averaged 38 inches with Morex and 96M5611 tallest at 45 inches and Idagold shortest at 30 inches.  Lodging was quite severe in the trial.  Many entries had over 90 percent lodging.  The new Utah variety Millennium and experimentals, UT005645 and UT005724, had best lodging resistance in the trial. 

Table 15 gives over-year yield and test weight averages for the Kimberly and Parma locations.  Entries with highest yield and at least two years of data include Baronesse, Steptoe, Moravian 14, Moravian 22, Tankard, C32, He6291, and Orca.  Moravian 14, CDC Dolly, and Orca were highest in test weight. 

Agronomic data for Craigmont is reported in Table 16.  Yield average was 77 bu/acre with Steptoe, 91Ab6526, and 92Ab5697 having 89 bu/acre.  C32 and He6890 had lowest yields of 65 and 64 bu/acre.  Test weights were good and averaged 51.2 lb/bu.  Several entries, including Camas, had test weights exceeding 53 lb/bu. Plump seed percent averaged 79 percent with a top of 96 percent (96M5611) and a low of 55 percent (96Ab8453).  Among earliest to head were UT005645 and UT005724.  Alexis was latest to head.  Nebula and 96Ab8453 were shortest in height (21 inches) and Morex was the tallest. 

Tammany data are given in Table 17.  Gallatin, Idagold, AC Metcalfe, and Steptoe were highest yielding entries and Morex was lowest yielding.  Test weight was very high with Camas tops at 56 lb/bu and only three entries below 50 lb/bu. Two entries, 86Ab1527 and 96M5611 recorded 100 percent plump and only three entries were below 90 percent (Idagold, Harrington, and Millennium).  UT005645 and UT005724 were again earliest in heading.  Alexis, Idagold, and Moravian 22 were among a group with equal but latest heading dates.  96Ab8453 was shortest (24 inches) and Morex and Steptoe tallest.  Lodging was moderate for the trial and averaged 3 (scale 1-9, 1=best) and ranged from 1 (12 entries) to 6 (Morex and Tango). 

Bonners Ferry data are given in Table 18.  Yield averaged 109 bu/acre and ranged from 139 (AC Metcalfe) down to 64 (Millennium).  Seven entries had test weight over 53 lb/bu and five entries were less than 48 lb/bu.  Percent plump averaged 91 percent and ranged from a high of 99 percent (C37) to a low of 60 percent (Millennium). 94Ab6661 was earliest to head (176 days) and seven entries were later than 190 days.  Crystal II and 96M5611 were tallest (32 and 33 inches) and Millennium and UT005724 were shortest (20 and 21 inches). Lodging was light in most entries, Morex had the highest lodging score. 

Combined data for Craigmont, Tammany, and Bonners Ferry is given in Table 19.  Eleven entries had average yield above 100 bu/acre.  Camas ranked 4^th highest at 104 bu/acre and had the highest average test weight (54 lb/bu).  96M5611 had highest percent plump (98%), UT005724 was earliest to head (171 days), and 96Ab8453 and He6291 were shortest (23 inches).  Yield and test weight over-years average is given in Table 20.  Merit, AC Metcalfe, and 95Ab11469 had highest yields over the 1998-99 period.

Preliminary Yield Nursery (PYN)

There were 70 entries in this trial.  Entries represent the breeding programs of Coors, Western Plant Breeders, Plant Breeders 1, and the USDA-ARS program.  The nursery was grown at Soda Springs, Moscow, and Tetonia (data courtesy of USDA-ARS and Tetonia R&E Center).  Soda Springs data are given in Table 21.  Average yield was 52 bu/acre with a high of 66 bu/acre (Colter) and a low of 36 bu/acre (97Ab7524).  Five entries had test weight of 53 lb/bu or greater and Steptoe had the lowest with 45.7 lb/bu.  Percent plump was relatively good with an average of 90 percent.  Range was from 98 percent (BZ594-20) to 63 percent (Harrington).  Foster and Morex were earliest to head (199 days).  Many entries failed to fully exert the heads due to drought stress, which may have resulted in some errors in recording heading date.  Several entries had heights only in the mid to high teens.  The tallest entries were Colter, Foster, and Morex (26-29 inches). 

Tetonia data are in Table 22.  Xena and 95M4623 (98 bu/acre) were highest yielding.  Yield ranged to under 70 bu/acre for some experimental lines.  Test weight averaged 52.3 lb/bu and was topped by five entries over 54 lb/bu and ranged down to about 49 lb/bu for several entries.  Percent plump averaged 94 percent and ranged from a high of 99 percent (nine entries) to a low of 73 percent for Harrington. 

The Moscow trial averaged 120 bu/acre (Table 23) with highest yields from Merit (135 bu/acre) and 95SR7A (134 bu/acre).  Test weight ranged from 44.8 lb/bu (Nebula) to 53.8 lb/bu (SL95511).  Percent plump averaged 90 percent, with five entries having 95 percent and Harrington the lowest at 73 percent.  Earliest heading date was recorded by PH596-086SSR (173 days) and the latest by PB1-97-2R-7065 (187 days), a spread of 14 days.  Lodging was light with only Morex having a rating below 2.

The combined averages for all three locations are given in Table 24.  Colter, Xena, Baronesse, CDC Lager, 95SR7A, and 95M4623 had highest yields (92+ bu/acre).  Four entries had test weight over 53 lb/bu (BZ594-20, SL 95511, C93-306, and PB1-97-2R-7090).  Foster, C95-54-9, and Morex were earliest to head and PB1-97-2R-7090 was latest. PH596-086SSR was the shortest and Morex tallest.  Table 25 gives the over-year average yield and test weight data.  Baronesse, 91Ab3332, Colter, 95M4623, and Xena had highest average yield for the 1998-99 period and C93-306 the highest test weight for the same period.   

Stripe Rust Barley Nurseries (ASRBN and OSRBN)

Entries from Aberdeen and Oregon that are thought to be resistant to Barley Stripe Rust were evaluated at Bonners Ferry and Moscow.  Table 26 gives results of the Moscow nursery for Aberdeen lines.  Stripe rust did not develop in 1999 in sufficient levels to rate varieties, so no rust data are given.  Two of the highest yielding experimentals were 94GH21-6 and 94GH51-4, which had similar yields to Baronesse and had better test weight.  Baronesse was highest yielding of the released varieties in the trial.  30 entries were in the trial. 

Bonners Ferry results for Aberdeen lines are in Table 27.  Baronesse and Crystal II were highest yielding released varieties with yields of 113 and 114 bu/acre.  Ten experimental lines exceeded these yields with 94GH89-5 producing the highest yield of 136 bu/acre.    Test weights were good with an average of 52.6 lb/bu and many of the lines were over 53 lb/bu.  Percent plump averaged 91 percent with a range of 98 to 77 percent.  Date of heading, height, and lodging all had the normal range for spring barley varieties. 

Table 28 gives the combined data for the Moscow and Bonners Ferry locations.  Several experimental lines compare favorably with the best of the released varieties. 

Tables 29, 30, and 31 give data for the lines from Oregon that were grown at Moscow and Bonners Ferry.  The Moscow trial had high yields (average 117 bu/acre) but low test weights (average 48.3 lb/bu).  The highest test weight was only 50.2 lb/bu (Orca) and ranged down to 44.9 lb/bu for Tango. 

Bonners Ferry yield averaged 104 bu/acre and ranged from 92 bu/acre (BCD 47) to 122 bu/acre for Baronesse.  Test weight averaged 51.1 lb/bu and ranged from 47.2 (Tango) to 52.3 for Acuario. 

For the combined data Table 31, Baronesse, Camas, and Harrington had top yields.  Crest and Harrington had highest lodging ratings. 

Stripe Rust and Russian Wheat Aphid Resistant Barley Nursery (SR/RWARBN)

These trials had 70 entries that mainly originated from Aberdeen breeding programs.  Results for Soda Springs are given in Table 32.  Bancroft and 95SR280C had highest yields (70 and 71 bu/acre) and MxDwarf the lowest (37).  The nursery average was 57 bu/acre.  Test weight averaged 50.3 lb/bu and ranged from 52.9 for Harrington to 36.0 for MxDwarf.  Percent plump averaged 94 percent for the trial.  All but eight entries were 90 percent or more.  Date of heading and height showed the normal range expected from a range of genotypes. 

Moscow data are given in Table 33.  Average yield for this nursery was 81 bu/acre and ranged from a high of 112 for Baronesse to a low of 58 for 95RWA241.  Test weight only averaged 47.6 lb/bu.  All entries were lower than normal as evidenced by Baronesse and Harrington, both with test weights less than 48 lb/bu. 

Combined data for the stripe rust and Russian wheat aphid nurseries are given in Table 34.  Baronesse, Steptoe, and 955R344B had the highest yields.  Test weight averaged 49.0 lb/bu and ranged from 40.4 (MxDwarf) to 52.0 for 95RWA82.  Percent plump averaged 73 percent with a range of 94 to 52 percent.

Hulless Barley Nursery (HBN and CHBN)

This nursery contained 50 entries that mainly originated from breeding programs at Aberdeen, Western Plant Breeders, and CDC Canada.  The trial was grown at Soda Springs, Aberdeen, Moscow, and Bonners Ferry.  An additional trial with 18 entries of Canadian origin was grown at Bonners Ferry.  Table 35 gives data for the Soda Springs location.  The yield averaged 43 bu/acre and was topped by hulled checks of Baronesse and Camas and the experimental line 97M5416, all with 51 bu/acre.  Godiva (22 bu/acre) and 95M3583 (29 bu/acre) were lowest in yield.  Test weight averaged 57.8 lb/bu, which reflects the higher test weight of hulless varieties.  The highest test weight was 62 lb/bu from CDC Candle.  A number of lines had a test weight of 60 or more.  Percent plump averaged only 45 percent.  Camas and Baronesse were highest (92 and 88 percent) and CDC Candle was lowest with only 7 percent plump. 

Aberdeen data are given in Table 36.  This location had high yields and very good overall growing conditions.  A severe windstorm occurred just as the trial was emerging and caused some stand loss in scattered plots, but the remaining plants tillered well and helped to give good overall production.  Highest yielding hulless lines were over 130 bu/acre with the highest yield 147 bu/acre (Baronesse was 149).  Test weight for the trial averaged over 60 lb/bu with highest entries having test weights in excess of 63 lb/bu.  Percent plump averaged 81 percent and ranged from 96 to 54 percent for hulless entries.  Plant height averaged 36 inches and ranged from a high of 41 inches to a low of 26.  Quite a few entries had lodging scores 4 and below. 

Moscow data are given in Table 37.  Top yields of hulless entries were in excess of 120 bu/acre compared to Baronesse and Camas with 138 and 137 bu/acre.  Test weights were more moderate, compared to Aberdeen, with an average of 52.9 lb/bu, which reflects some stress during the grain filling period.  Percent plump averaged 75 percent.  Plant height averaged 36 inches, the same as at Aberdeen.  Lodging scores were less at Moscow with an average of 2 compared to an average of 3 at Aberdeen. 

The Bonners Ferry trial (Table 38) averaged 104 bu/acre.  Highest yielding hulless entries were again in the 120 bu/acre range.  Test weight averaged 54.1 lb/bu and percent plump was 78 percent.  Lodging scores were similar to Moscow and averaged 2. 

Table 39 gives the combined averages for Moscow and Bonners Ferry.  Highest average yields were obtained from 97M5194 (126 bu/acre), 96AH920 (122 bu/acre), and 98AH444 (121 bu/acre).  Highest average test weight was from Godiva (58.7 lb/bu) and HB 347 (59.0 lb/bu).  Many entries had plump percentages over 80.  Date of heading and heights are in the normal range of spring barley entries. 

Table 40 gives yield and test weight data averaged over years entries have been in trials for Soda Springs, Moscow, and Bonners Ferry.  Averaged over the 1998-99 seasons, 96AH886 is the top yielding hulless entry and had a yield of 80 bu/acre compared to 91 for Baronesse. 

Table 41 gives the data for the Canadian hulless nursery.  CDC Dolly was the hulled check used in the trial.  Highest yielding hulless entries were about 12 bu/acre lower  compared to the check.  Test weights ranged from 61 lb/bu down to the lower 50’s.  Falcon was lowest yielding and HB903 had the lowest test weight. 

Non-replicated Barley Nursery (NRBN)

Table 42 contains data from the non-replicated nursery that was grown at Moscow.  This trial contained 380 entries and originated from many regional breeding programs.  Entries were mostly hulled but a significant number were hulless or were segregating for the hulless condition.  Selected check varieties were used periodically as comparisons for the entries.  Yield levels were quite high for this nursery, giving good spread to performance numbers and will allow good progress in eliminating lines with poor performance potential. 

Uniform Northwestern States Oat Nursery

The uniform regional oat trial contained 28 entries.  Entries originated from many regional breeding programs.  The trial was grown at Moscow and Bonners Ferry.  Moscow data are given in Table 43.  Average yield was 158 bu/acre and ranged from 182 (87AB5632) to 145 bu/acre for 87Ab4983, 90Ab1322, and Prairie.  Test weight was good as indicated by the average of 37.3 lb/bu.  There was little lodging in the nursery. 

Bonners Ferry data are given in Table 44.  Yields ranged from 169 bu/acre (94Ab5543) to 106 bu/acre (Rio Grande).  Test weight was a good 40.4 lb/bu and all entries were 39 lb/bu or more.  Lodging was not severe in the trial. 

Table 45 gives the combined data for Moscow and Bonners Ferry.  Highest average yield was from 94Ab5543 with 161 bu/acre.  Highest yield for a released variety was 152 bu/acre for CDC Pacer.  ND860416 and ND910569 had highest test weights averaging over 41 lb/bu.  Ajay was the shortest entry at 27 inches tall and Derby the tallest at 41 inches. 

Yield and test weight data averaged over-years are given in Table 46.  ND930122 and AbSP9-2 have the highest yield averaged over the 1998-99 growing seasons.
