Introduction
This report summarizes the results of the data collected by the BEP program during the 2000-2001 growing season. Three winter barley and twenty-four spring barley trials were established at eleven locations throughout Idaho during the fall of 2000 and spring of 2001. All trials were harvested but the data from the Western Dryland Spring Barley Nursery at Soda Springs was deemed unusable due to extreme variation caused by drought. Jerome, Parma and Moscow had winter barley trials. Spring trials were grown at all locations listed except Jerome. 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 is 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 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, 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, percent plump and thins 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%
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. Percent thin is that part of the sample that passed through a 5/64
screen after 25 cycles of shaking. Spring stand is reported on a scale of 1-9
with 9 being the best stand. Stand data was taken in selected nurseries that had
differential stand emergence. Selected samples of hulless barley will be pearled
and evaluated for suitability for export market. Additional evaluations for
quality determination may be conducted.
Statistical Interpretation
Most tables have a least significant difference
(LSD) statistic at the bottom of the table. These data are given at the 5% 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%. 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 approximation to a
combined LSD was calculated. The coefficient of variation (CV) statistic 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)
Grain yields at Moscow were significantly lower this year. The entire trial of 50 entries averaged 139.7 bu/A, with 93Ab669 (172.8) the highest yielding entry and 97Ab11 (103.7 bu/A) the lowest yielding entry. Dry summer conditions contributed to these lower yields. Test weights were also lower. Highest test weights were from the 2-rowed varieties Pipkin and Puffin (55.5 and 54.6 bu/A) and 96Ab11 of the 6-rowed entries (52.9). Lowest test weights were WA2684-89, 97Ab23, 96Ab907 and Hundred. All had test weights lower than 49 lb/bu. Two Oregon selections, ORStab 7 and ORStab47, were the earliest to head. Puffin, 85Ab216, 94Ab1269 and 94Ab1274 had the highest percent plump (98%0 and BZ596-21 had the lowest (56%). The plant height in this nursery was unusually short due to lack of moisture. The shortest entry was BZ596-21 (21 inches) and the tallest entry was ORStab 47 (37 inches). Data are in Table 3.
Table 4 and table 5 give the combined data for the Jerome, Parma and Moscow trials. Table 6 gives yield and test weight data over years for those entries in the trials either 2 or 4 years. For all varieties that have at least 4 years of testing, Sunstar Pride has the highest yield followed by 91Ab603. For entries with only two years of testing, Sunstar Pride and 91Ab603 again have the highest yields.
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.
Genesee data
are in Table 7. Grain yield for the entire trial averaged 138.7 bu/acre and
twenty-six entries had yields over 140 bu/acre.
Test weight averaged just over 52 lb/bu, slightly lower than last year.
Highest test weight entries included CDC Helgason, 85Ab2323, Farmington,
94Ab12990, and MT970116, all over 54 lb/bu.
Steptoe had the lowest test weight. Percent plump seed averaged 85
percent with Xena topping the trial with 94 percent. Munsing recorded lowest
percent plump. Munsing, Steptoe,
and BZ594-2089 were earliest to head, and Merit was latest.
MT960099 and Munsing were shortest in height and 94Ab12990, 85Ab2323,
Legacy, and 6B95-2089 were tallest. Most entries had some lodging with a nursery
average of 4 (scale 1-9, 1=best). Twenty-two
entries had a ranking of 5 or greater.
Western Spring Barley Nursery (WSBN)
The WSBN 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 Genesee and Bonners Ferry. Entries in this trial represent the most advanced materials from breeding programs in surrounding states.
The nursery average at Genesee (Table 9) was 137.0 bu/ac with 94Ab13449 (170.4 bu/ac) having the highest yield and eleven additional entries at or above 150 bu/ac. All entries exceeded 110 bu/ac. Test weight was above average for spring barley with an average of 51.2 and a range of 54.6 lb/bu to 47.4 lb/bu. These averages were slightly lower than last year. Percent plump ranged from 89 (BZ596-117) to a low of 39 for Colter. Height ranged from 29 inches (DA587-124) to 42 for Legacy. The trial had severe lodging this year, with almost half of the nursery scoring 7 (scale 1-9, 1=erect) or higher.
Table 10 gives data from Bonners Ferry. This nursery was adversely effected by an infestation of wild oats, and this data will not be included in multi-location or multi-year tables. Yield averaged 33.7 bu/ac with highest yields from MT960228, BZ596-117 and 96SR149C. Drummond, Stander and DA587-124, all less than 23 bu/ac, recorded lowest yields. Test weights were generally good with an average of 49.3 lb/bu with a high of 52.0 for WA8682-96 and ranging down to a low of less than 46 lb/bu for 92Ab5180. Percent plump seed averaged 82 and ranged from, 92 for UT97B1480-1632 down to 64 for Millennium. Steptoe and UT97B1480-1632 were earliest to head. Nebula was the shortest variety and 95SR149C at 23 inches tall, was the tallest. No lodging data was taken because no lodging was present.
Table 11 gives yield and test weight data averaged over years. Stander and Nebula had highest yields over 1997-2001 period and Millennium had the top yield over the period 2000-01.
Advanced Yield Nursery (AYN)
The AYN had 70 entries primarily composed of advanced lines from the Aberdeen breeding project. The Fairfield nursery included five extra entries at the request of local farmers. The trial was grown in two locations in southern Idaho and four locations for northern Idaho. Fairfield, a dryland location, received very little moisture during the growing season and temperatures were warmer than normal. As a result, growth was restricted throughout the season and yields were low. Parma had favorable growing conditions throughout the season. Craigmont had above average yields of over 90 bu/ac and had favorable growing conditions throughout the season. There were no diseases or insect pests of note. Tammany had very dry conditions causing all soil variations to show up drastically, thus explaining the high CV's in yield. No disease or insect pests were recorded. Growing condition at Potlatch were also drier than normal with lower than average yields. Bonners Ferry was also very dry and had a heavy infestation of wild oats. The soil and weather conditions were adverse for weed control. Because of this situation, data from Bonners Ferry is not included in multi-location or multi-year tables.
Table 12 gives data from Fairfield. Highest yields were from 95Ab11469 (34.4 bu/ac), Hector (33.1 bu/ac), and Colter (32.6 bu/ac). Lowest yield was 12.1 bu/ac from 2B97-4299. Test weight averaged 50.3 lb/bu. PB1-95-2R-522 had the highest test weights at 54.6 lb/bu. Twenty-five entries had 52 lb/bu test weight or greater. Foster, Nebula, Steptoe and 93Ab688 all had less than 46 lb/bu test weight. Percent plump was 66 percent for the nursery average and ranged from a high of 91 for C46 to a low of 29 for Millennium. Many entries were very short with Nebula and DA587-124 only 12 or 13 inches tall. The tallest height recorded was only 20 inches for Walker.
Parma data are given in Table 13. Conditions for the Parma trial were generally very favorable and the trial developed well. Nursery average yield was 138.8 bu/ac and ranged from 193.0 bu/ac for C46 to 99.4 for Legacy. Other entries with high yields included PB1-95-2R-522 (178.7), and C53 (167.2). Test weight was high averaging 53.3 for the entire trial. Twelve entries had weights above 54 lb/bu. Lowest test weights were from 92Ab5180 and Steptoe. Percent plump seed was also very good with overall average 96 percent and a range from 99 percent for Moravian 14 to a low of 87 percent for IdaGold II. 91Ab3148, UT97B1480-1632 and Morex were earliest to head. Plant height averaged 36 inches with 94Ab12990 tallest at 42 inches. DA587-124 was the shortest at 27 inches. Lodging was moderate in the trial. Many entries had a 5 or higher lodging.
Agronomic data for Craigmont are reported in Table 14. Yield average was 91.1 bu/ac with eleven varieties having yields over 100 bu/ac. Steptoe was the highest yielder at 108.2 bu/ac. IdaGold II and 6B95-2089 had lowest yields of 74.9 and 75.8 bu/ac. Test weights were good and averaged 54.1 bu/ac. Two entries, PB1-95-2R-522 and 94Ab12990, had test weights exceeding 56 lb/bu. Lowest test weights were from Nebula, and 92Ab5180. Plump seed percent averaged 90 with a top of 98 percent for Moravian 37 and a low of 64 percent for Millennium. Earliest to head was Moravian 14, C40 and Orca. 95SR316A, C46, C57, 95SR149C and Merit were latest to head. Nebula and DA587-124 were shortest in height (21 or 20 inches) while Morex was the tallest.
Tammany data are given in Table 15. Yields were extremely low and variable due to drought conditions this summer. Yield average was 61.1 bu/ac with only WA8682-96 yielding better than 90 bu/ac. DA587-124 and Millennium had the lowest yields, both less than 40 bu/ac. Test weight was an average of 51.6 lb/bu. Camas had the highest test weight of 54.9 lb/bu and 92Ab5180 at 45.6 lb/bu the lowest. Three entries, Orca, 95Ab11469 and 91Ab6526 recorded 97 percent plump and Galena the lowest plump with 61 percent. Orca, 94Ab13449, Moravian 14, 97Ab8333 and UT97B1480-1632 were earliest in heading. the trial had an average heading date of 159. DA587-124 was shortest (17 inches) and Foster the tallest (34 inches). There was very little lodging, due mostly to the extremely dry summer.
Data for Potlatch are found in Table 16. Merit had the highest yield with 97.3 bu/ac. Colter had the lowest yield at 61.5 bu/ac. Test weight was lower this year with an average of 52.7 lb/bu topped by 98Ab11771 at 55.2 lb/bu. UT95B1216-4087 had the lowest test weight. Percent plump was good with an average of 91 percent. Three entries, Moravian 37, C56 and C40 shared top spot with 98 percent and UT95B1216-4087 and Millennium were lowest with 69 percent. C40 was the earliest in heading and 95SR149C was latest. Nebula and DA587-124 were shortest and Morex was the tallest. Lodging was insignificant.

Over four years, the highest test weight was recorded by Camas at 52.9 lb/bu. Highest average test weight during the 2000-2001 period was SL95511 at 53.9 lb/bu.
Stripe Rust and Russian Wheat Aphid Resistant Barley Nursery
Two trials were grown this year, both at two locations, Soda Springs and Genesee. The main trial contained 60 entries. The second trial was a back-crossed trial that contained 200 entries. The 200 entry trial is a cooperative effort led by Drs. Dolores Mornhinweg and Phil Bregitzer.to introduce genes for RWA resistance, that have been identified in barley accessions from the National Small Grains Collection, into cultivated germplasm. The data produced from this nursery, in conjunction with other nurseries grown in other locations, will be used as the basis for a series of germplasm releases, of superior lines from each of the germplasm resistance source combinations. Both nurseries originated mainly from Aberdeen breeding programs.
Data from Soda Springs are given in Table 33. 98ID180 and Steptoe had the highest yields (61.8 and 61.6 bu/ac) and 95SR176B the lowest (36.8 bu/ac). The nursery average was 53.8 bu/ac. Test weight averaged 50.7 lb/bu and ranged from 52.7 fir 98ID243 to 47.2 for Steptoe. Plump averaged 87 percent for the trial. 96RWA1194, 96RWA1192 and Stander were among the earliest to head. The latest entries were about 5 days later than the earliest. There was only four inches difference between the tallest and shortest entries.
Genesee data are given in Table 34. Average yield for this nursery was 88.0 bu/ac and ranged from a high of 102.3 for Garnet to a low of 65.6 for Colter and Steptoe. Test weight averaged 52.6 lb/bu. Average plump was 87 percent. Steptoe was the earliest to head, 95SR19D and 98ID63 were the shortest at 24 inches tall and Morex at 35 inches tall, the tallest. There was very little lodging.
Combined data for the Stripe Rust and Russian Wheat Aphid Resistant nurseries are given in Tables 35 & 36. Baronesse and Camas ranked 1st and 11th in yield for the combined location average indicating many of the entries have good yield potential. Test weight, percent plump and other agronomic data are in line with the check varieties.
Table 37 contains the multi-year data for the Stripe Rust and Russian Wheat Aphid Resistant nurseries. Data are given for the 2-year period 2000-01 and four-year period 1998-2001. Baronesse had the highest yield over both the 2-and 4-year period. All experimental entries have higher yield for the 4-year period than Colter. 95SR296C had the highest test weight over the 4-year period and Camas had the highest test weight over the 2-year period.
Table 38 contains the data from the backcrossed nursery at Soda Springs. Yield ranged from 69.8 bu/ac (00ST1156) to 22.6 bu/ac (99ST1151). Harrington had the highest yield (129.6 bu./ac) fro the check varieties that were randomly placed throughout the trial for comparison purposes. Test weights ranged from 54.1 to 21.0 lb/bu.
Table 39 contains the data from the backcrossed nursery at Moscow. Yield ranged from 139.7 bu/ac (97ID1269A) to 48.2 bu/ac (00ST2067). Garnet had the highest yield (129.6 bu/ac) for the check varieties that were randomly placed throughout the trial for comparison purposes. Test weights ranged from 55.3 to 45.3 lb/bu.
Hulless Barley Nursery (HBN)
Two hulless trials were grown in 2001. The main trial (HBN) contained 30 entries, the majority of which originated from breeding programs at Aberdeen and CDC Canada. This trial was grown at Soda Springs, Aberdeen, Genesee, and Bonners Ferry. An additional (CHBN) trial with 25 entries of Canadian origin was grown at Soda Springs and Bonners Ferry. The main trial is described first.
Table 40 gives data for the Soda Springs location. The yield averaged 57.8 bu/ac with the hulled checks Baronesse (65.1 bu/ac) and Camas (63.1 bu/ac) and CDC McGwire (57.4 bu/ac) highest in yield. 96M5505 (50.8 bu/ac) and CDC Candle (51.9 bu/ac) were lowest in yield. Test Weight averaged 59.8 lb/bu, which reflects the higher test weight of hulless varieties. The highest test weight was 62.5 lb/bu from CDC McGwire. Twenty-one of the lines had a test weight of 60 lb/bu or more. Plump averaged 87 percent. 96AH930-1 was highest (95 percent) and 99AHF4-770 was the lowest with only 68 percent plump.
Aberdeen data are given in Table 41. Average yield was 135.2 bu/ac with the highest hulless variety yielding 159.8 bu/ac (Camas, a hulled check variety was 180.6). Test weight fot he trial averaged 55.3 lb/bu with 96M5608 and CDC Freedom having the highest test weight of 59.4 lb/bu. Plump averaged 56 and ranged from 85 to 26 for hulless entries. Plant height averaged 32 inches and ranged from a high of 37 to a low of 24 inches.
Genesee data are given in Table 42. 96AH930-1 had the highest hulless yield at 101.2 bu/ac. This compares to check varieties Baronesse and Camas with 89.6 and 82.3 bu/ac. Test weight averaged 58.8 lb/bu with 96AH930-1 having the highest (62.3 lb/bu). Plump averaged 52 percent with hulless lines ranging from 79 to 23 percent. Plant height averaged 29 inches, the check varieties Baronesse and Camas were 26 and 27 inches tall. Lodging scores averaged 1 (scale of 1-9 with 1=erect).
The Bonners Ferry trial (Table 43) averaged 28.3 bu/ac. Highest yielding hulless entries were 99AHF4-752 and 96AH545 at 43.58 and 38.3 bu/ac, respectively. Test weight averaged 56.4 lb/bu and the highest test weight was 60.8 lb/bu. Average plump was 60 percent and had a range from 87 to 34 percent. There was no lodging. Date of heading and height were in an acceptable range of variation for the entries. This nursery was adversely effected by an infestation of wild oats, and this data will not be included in multi-location or multi-year tables.
Tables 44-48 give the combined averages for Aberdeen, Soda Springs and Genesee. Highest combined yields were obtained from Camas at 108.7 bu/ac, followed by Baronesse at 105.5 bu/ac. Highest combined yield for the hulless varieties was 96AH930-1 (97.9 bu/ac). Highest average test weight was from 96M5608 (61.1 lb/bu) and 96M5610 (60.7 lb/bu). Plump averaged 65 percent across all locations with Soda Springs having the highest average. 96M5607 had the highest plump average of all hulless entries. Ten hulless entries were earlier to head than Baronesse, the earliest hulled check. Four hulless entries were shorter than Baronesse.
Table 49 gives yield and test weight data of the HBN averaged over years for Aberdeen, Soda Springs, Genesee and Bonners Ferry locations. Over the four-year period from 1998-2001, 96M5288 was the highest yielding hulless variety at 84.5 bu/ac. Over the 2-year period 2000-01, 96M5288 was again the top yielding hulless entry and had a yield of 88.8 bu/ac compared to 101.6 for Camas. 96M5608 had the highest test weight over both the 4-year and 2-year period with 59.3 lb/bu and 60.4 lb/bu.
Table 50 gives the data for the CHBN nursery as Soda Springs. CDC Dolly was the hulled check used in the trial. Average yield was 48.4 bu/ac with entry HB111 having the highest yield at 57.1 bu/ac (for hulless entries), CDC Dolly had a yield of 52.6 bu/ac. Test weight averaged 60.1 lb/bu and ranged from 62.7 to 52.9 lb/bu.
Table 51 gives the data for the CHBN nursery at Bonners Ferry. Yield ranged from 39.6 bu/ac for HB367 down too 14.1 bu/ac for the lowest yield. The hulled check CDC Dolly had a yield of 31.1 bu/ac. Location average was 28.0 bu/ac. Test weight averaged 55.8 lb/bu and ranged from 61.1 down to 47.1 lb/bu. HB515 had the lowest test weight.
Non-replicated Barley Nurseries
These two trials contained 241 entries, originating primarily from private regional breeding programs. Non-replicated trials are grown to give breeding organizations preliminary agronomic data from areas where they would otherwise not obtain data. This will allow them to more effectively eliminate lines with poor adaptation. Selected check varieties were randomly placed throughout the trial for comparison purposes.
Table 52 contains data from the non-replicated nursery grown at Soda Springs. This trial had 37 entries. Yield ranged from 52.0 bu/ac (99ST1352) to 27.2 bu/ac (99ST1113). Camas had the highest yield for the check varieties and ranked 2nd.
Table 53 gives the data for the Genesee nursery. This trial had 204 entries. Yields ranged from 178.6 bu/ac (SAL 8) to 65.0 bu/ac for a hulless selection 00AH3778. The highest yielding check variety was ranked 15th.
