1990 Barley Variety Trials
R.L. Dovel and G. Chilcote'
INTRODUCTION
Barley variety trials planted at the Klamath Experiment Station (KES) in
1990 included: the Western Regional Spring Barley trial in cooperation with
Western State plant breeders; the Intermountain Spring Barley trial in
cooperation with University of California research and extension personnel;
and a collection of new and promising lines from the Oregon State University
barley breeding program. The trial in cooperation with OSU was planted at KES
and at two sites in the Lower Klamath Lake area.
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 continuously in spring cereals. All plots at KES were
sprinkler irrigated, while only one organic soil test site was irrigated.
All trials were arranged in a randomized complete block design with either
three or four replications. Trials at the KES were planted between April 25
and 27. Plots at the irrigated organic soil site were planted on May 26 and
the dryland study was established on May 31. Seed was planted to a depth of
one inch at a seeding rate of 100 lbs/A. All plots were fertilized with 100
lbs N, 60 lbs P 2 0 5 , and 44 lbs S/A at time of seeding. Plots measured 5 x 20
feet with a row spacing of six inches. At KES, Bromoxynil and MCPA were
applied at labeled rates to control broadleaf weeds. Chemical weed control at
organic soil sites was achieved using a mixture of 2,4-D and Banvel. Plots
were harvested using a plot combine with a five foot wide head. 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 in the Western Regional Barley Nursery were high in 1990, with the
average yield exceeding the 1989 trial by more than 1,800 lbs/A (Table 1).
There was no evidence of common root rot in the plots in 1990 while this
disease, caused by Cocleolebus spp., definitely lowered yields at KES in the
previous year. Despite higher yields, test weights were lower in 1990 than in
1989. Steptoe had the lowest test weight in the trial (47.5 lbs/bu); however,

it yielded well (6,364 lbs/A). Although there were no varieties that produced
grain yields significantly higher than Steptoe, both OR 2 and OR 3 were
slightly higher in yields (6,849 and 6,803 lbs/A, respectively). Good performance of these two varieties in trials on organic soils is also encouraging.
The release of one of these lines as a feed barley is being considered. The
highest yielding entry in 1990, WP 584118 (6,850 lbs/A), was one of the
lowest yielding entries in the trial in 1989. Further testing is needed to
determine the yield potential of this variety in the Klamath Basin.
OSU Spring Barley Variety Trials
Yields in the OSU Spring Barley Variety Trial at KES were comparable to
those of the Western Regional Spring Barley Nursery. Both Lower Lake sites
were lower yielding. The unirrigated trial received considerable hail damage
with an estimated loss of 30 - 50%. The irrigated organic soil trial exhibited severe signs of stress shortly after emergence. Although plants did
recover, yields were substantially depressed. It was not determined what
caused the stress but both frost and herbicide injury are possible causes.
An experimental line from Idaho, 79 Ab10719-66LC, was the highest yielding
entry at KES (Table 2). When averaged across all three sites it produced
yields significantly higher than Steptoe but only slightly higher than Gustoe
(Table 2-5). The OSU line, ORS 3, was only slightly lower yielding when
averaged across all three locations and was the highest yielding line at the
irrigated organic soil site. These two lines both show promise as feed
varieties for the Klamath Basin. While the malting characteristics of ORS 3
are not appropriate for use in the United States malting industry, further
testing is underway to determine if malting quality of this variety is
appropriate for use in the export malt industry. The 2-row malting line, ORSM
8408, produced yields comparable to Crystal, the new 2-row malting standard,
in all three locations. This selection is currently in plant scale malt
testing.
Another malting variety that looked very promising is Russell. This 6-row
malting variety produced yields equivalent to or superior to Steptoe at all
three locations. This could be a commercially viable option if malt contracts
are offered for this variety in the Klamath Basin.
The two leading commercially available varieties in this trial were Gustoe
and Columbia. Gustoe has consistently out-yielded Steptoe in the Klamath
Basin. Columbia has usually produced yields comparable to or superior to
those of Steptoe. These higher yielding varieties require higher management
levels (especially irrigation management) in order to realize superior yield
levels.
Interest has increased recently in naked barley for use in human food products. Barley has a higher B-glucan content than oats. B-glucans have been
reported to reduce blood cholesterol levels and the use of naked barley in
health food products is possible. Several lines of naked barley were included
in the trials. Nupana, Shonkin, Wanupana, and Washanupana were obtained from
130
Montana State University (MSU). Another line, called Hulless in these trials,
was obtained from a local grower. The MSU lines are all 2-row varieties,
Hulless is a 6-row barley. The yields of the 2-row varieties were 1,000-1,800
lbs/A lower than the average plot yield in all locations . In contrast,
Hulless yield was about 300 lbs/A less than the average plot yield. However,
yields of Hulless were up to 2,000 lbs/A lower than the highest yielding
entries. Incentives would have to be substantial to make production of these
lines economically attractive. Efforts to improve yield potential and marketability of naked barley are currently underway.
Intermountain Spring Barley Variety Trial
Yields in the Intermountain Spring Barley Variety Trial were slightly
higher in 1990 than in 1989 and roughly equivalent to 1988. Grain yields
ranged from 4,317 to 7,337 lbs/A in 1990 (Tables 6 and 7). Test weights
averaged 52.8 lbs/bu, ranging from 50.0 to 56.5 lbs/bu with one exception.
Hulless produced a test weight of 59.0 lbs/bu.
There were no numbered entries with higher yields than the two leading
commercially available varieties in this trial (Gustoe and Columbia) during
the last three years. However, when averaged over a three-year period, OSB
783063, ORSM 8424, and ORSF 8424 had yields which were equivalent to or
superior to Steptoe, a commonly planted variety in the Klamath Basin.
