Spring Barley Variety Screening, 1996 R.L. Dovel l , R.S. Karow 2 , and G. Chilcote l Introduction Spring barley accounts for about 80 percent of cereal crops grown on over 100,000 acres in the Klamath Basin. Both feed and malting types are important in the region. Barley variety trials planted at the Klamath Experiment Station (KES) in 1996 included entries in the Western Regional Spring Barley trial done in cooperation with western states plant breeders and a collection of new lines from the Oregon State University (OSU) barley breeding program. The trial, in cooperation with OSU, was planted at KES and at two sites in the Lower Klamath Lake area. Screening of early selections from Idaho, Montana, and Washington breeding programs was also conducted in non-replicated trials. Procedures All small grain variety trials at the KES were planted on land that was cropped in potatoes the previous year. Soils at the station include Poe, Fordney, and Hosley series, all of which have a fine-loamy to sandy texture, and are moderately deep and somewhat poorly drained. The off-station trials were on very deep, poorly drained, lake bottom soils with high organic matter content. These fields are cropped in spring cereals continuously. All plots at KES were sprinkler irrigated. Only one organic soil site was irrigated. All trials were arranged in a randomized complete block design with four replications. Crops at the KES were planted on May 7 and 8. Unirrigated and irrigated organic soil sites were planted on May 2 and 30, respectively. Seed was planted to s a depth of one inch at a seeding rate of 100 lb/acre. All plots were fertilized with 20 lb N, 12 lb P205, and 9 lb S/acre at time of seeding. Additional fertilizer was broadcast prior to planting at 80 lb N, 48 lb P2O5, and 35 lb S/acre. Plots measured 5 x 20 feet with a row spacing of 6 inches (10 rows). At KES, bromoxynil and MCPA were applied at labeled rates to control broadleaf weeds. Weed control at organic soil sites was achieved with a mixture of 2,4-D and Banvel. Plots were harvested in mid to late September using a plot combine with a 5-foot wide header. Grain yield was recorded for all plots. Test weight, percent plumps, and percent thins were measured in only one replication. Results and Discussion OSU Spring Barley Trials Mineral Soil Site Average yield was similar to that in 1995 but lower than in 1994. A late season infestation of barley stripe rust (B SR) reduced yields slightly. Stander was the highest yielding entry in the trial in 1996 (Table 1). It produced significantly higher yields than eight entries in the trial, including Steptoe. Due to high variability in the trial, more precise mean separation was 1 / Associate Professor, and Research Technician, respectively, Klamath Experiment Station, Klamath Falls, OR.

Other varieties in the trial that produced in excess of 5,000 lb/acre included BA 1202, Ab-2317, Baronesse, Foster, Maranna, and Galena. Test weight averaged 50.9 lb/bu at this site. Both WPB BZ489-74 and WA 11045-87 had exceptionally high test weights, but lower than average yields. Crest, BA 1202, and Baronesse had 25, 12, and 3 percent lodging compared to 15 percent for Steptoe. Serious lodging was observed in three experimental lines (Table 1). Other high yielding lines did not lodge. When yield is averaged over the last two years, Baronesse is the highest yielding entry, followed by Stander, Maranna, and Colter (Table 2). Over a three-year period Maranna is the highest yielding entry followed by Baronesse, Colter, and Russell. Colter is extremely susceptible to BSR. Its yields and relative ranking have declined since the disease was introduced into the area in 1995. Two hulless lines, WPB BZ489-74 and Waxbar, had significantly higher grain protein concentrations than other trial entries. Irrigated Organic Soil Site Gus was the highest yielding entry at this site in 1996 (Table 3), followed closely by UCD 92-10591R-117, a BSR resistant line. Both of these entries produced significantly higher yields than Steptoe. Four European lines, Alexis, Tyne, Optic, and Chariot, were included in the organic soil sites and in a separate trial at KES. These late maturing two row lines were as susceptible to BSR as domestic spring barley varieties. Due to later maturity, these varieties had lower than average yields. Several varieties produced low test weights. The hulless variety, Bear, was highest in test weight due to the absence of hulls, but also had fewer plumps for the same reason. Similar results were observed at all three sites. The top yielding varieties at this site over the last two years were Colter, Gus, Stander, and Russell (Table 4). Colter produced the highest yield at this site over three years. 90 Unirrigated Organic Soil Site For the second year in a row, a severe frost in mid-August damaged heads in the early stages of grain fill, resulting in low test weights and yields. The trial was not harvested in 1995, but damage was less severe in 1996 and data were collected. The average yield was only 1,650 lb/acre and average test weight was 46.9 lb/bu (Table 5). The highest yielding entry in the trial, Baronesse, produced 2,970 lb/acre and was second highest in percent plump kernals. Colter and Russell produced yields that were not significantly different than Baronesse. Yields of later maturing varieties were especially low. Steptoe treated with Vitivax and Steptoe treated with Baytan were included in all trials. Baytan treatment resulted in substantially higher yields at the mineral soil site, similar yields at the unirrigated organic soil site, and slightly lower yields at the irrigated organic soil site. Similarly inconclusive results were obtained from field scale and small plot studies at three sites in the Klamath Basin. It appears that late season BSR infestation occured after the window of protection provided by this fungicide had passed in 1996. Western Regional Spring Barley Nursery Yields were low and variability was high in the 1996 trial (Table 6). The trial average yield was the lowest since 1989, when common root rot severely reduced yields. Common root rot and BSR were present in 1996. Although barley stripe rust infestation occurred late in the season, the combination of both diseases reduced yields to 60 percent of expected levels. High producing entries that were in the trial the previous two years also produced relatively higher yields in 1996, but mean separation was not possible due to high variability in the trial. Top yielding varieties over the last three years include BA 2B914947, MT 890008, BA 2B89-4311, and ND 11055 (Table 7).
