Spring Barley Variety Screening, 1993
R.L. Dovel 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 1993 included
entries in the Western Regional Spring Barley trial done in cooperation with western
states plant breeders, and a collection of new and promising 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. Early selections from
Idaho, Montana, and Washington breeding programs were screened in non-replicated
trials at KES.
PROCEDURES
All small grain variety trials at the KES were on land planted 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 between May 17 and 19. Irrigated and
unirrigated organic soil sites were planted on June 9 and 24, respectively. Seed was
planted to a depth of 1 inch at a seeding rate of 100 lb/A. All plots were fertilized with
100 lb N, 60 lb P2 05 , and 44 lb S/A at time of seeding. 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 late September at the KES
and in late October at off-station sites 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
Western Regional Spring Barley Nursery
Yields were lower in 1993 than in 1991 or 1992 (Tables 1 and 2). This is partially
due to high infestations of both wheatstem maggot and common root rot. Data was not
collected on wheatstem maggot damage on this trial, but in an adjacent study over 50
percent of the tillers were damaged by this pest. Lower than normal yields may also be
due to cooler than normal temperatures throughout the growing season and to later than
normal planting dates due to cool and wet spring weather. Despite lower yields in 1993,
test weights were generally good, averaging 51.9 lb/bu. UT 11640 was the highest
yielding entry in 1993; however, yields of Steptoe, UT 1705L, UT 1705D, and BA 2B885648 were not significantly different than UT 11640 (Table 1). UT 11640 was also one of
the highest yielding entries in 1992 and the highest yielding entry when averaged over
two years (Table 2). Although UT 11640 was high yielding, it produced low test weights
in both 1992 and 1993 (49.5 lb/bu in both years). BA 2B88-5648 produced both high
yields and test weights in 1993 (4,340 lb/A and 55.5 lb/bu).
OSU Spring Barley Trials
OSU spring barley variety trials were established at three different locations. The
24-entry trial was located at the KES on mineral soil and at two organic soil locations on
the Lower Klamath Lake. One organic soil site was irrigated by overhead sprinkler
irrigation. The other site was flood irrigated prior to planting, with no further irrigation.
Yield trends over the past three years at KES were similar to those seen in the
Western Regional Spring Barley Nursery discussed above. Wheatstem maggot damage
was extensive in 1992 and 1993, and undoubtedly reduced yields. Yields were further
reduced in 1993 by a severe infestation of common root rot. Baroness was the highest
yielding entry in 1993 (Table 3). Other entries that were not significantly different than
Baroness include Steptoe, BA 1202, Klages, and ORS 3.
Over a three-year period, top yielding entries include ORS 3, Gustoe, Steptoe,
Maranna, and Columbia (Table 4). Two-row varieties such as Baroness, Bearpaw,
Crystal, BA 1202, and Harrington had test weights above 54 lb/bu (Table 3). Six-row
varieties tended to have lower test weights, averaging about 51 lb/bu. Six-row varieties
with higher than average test weights included Russell and Maranna, which had test
weights of 53.0 and 53.5 lb/bu, respectively.
Colter was the highest yielding entry at the irrigated organic soil site for the fourth
consecutive year (Table 5). Other entries not significantly different from Colter at this
site in 1993 included ORS 3, Gustoe, BA 2601, PH 585-6, and Russell. When averaged
over three years, Colter produced grain yields significantly higher than all entries except
Gustoe and Russell at the irrigated organic soil site (Table 6). Later than normal
planting dates in 1992 and 1993 resulted in lower yields than in 1991 (Table 6). Late
planting and lower than normal temperatures with occasional frosts resulted in very low
test weights at this site in 1993, averaging 42.8 lb/bu (Table 5).
75
Late planting combined with mid-August frosts greatly reduced yield and test weight
at the unirrigated organic soil site. Grain yield averaged just over 1 ton/A and average
test weight was 35 lb/bu (Table 7). In 1993, Colter produced average yields and test
weights at the unirrigated organic site. In 1992, Colter produced significantly more grain
than all other entries in the trial (Table 8). Colter averaged 4,421 lb/A at the unirrigated
organic soil site over a three-year period, significantly more than many other entries in
the trial, but not Excel, Gustoe, Steptoe, or Russell (Table 8).
