A
bstract
Statewide barley variety trials were
established in three locations across
Klamath County in 1997, at the Klamath Experiment Station (KES) on mineral soil, at an irrigated
organic soil site, and at an unirrigated organic soil
site. The Western Regional Spring Wheat
Nursery was also establised at KES. Barley
stripe rust (BSR) has been an important factor in
barley yield in the region for the past 3 years.
Several varieties with better resistance to BSR
than commonly grown varieties such as Steptoe
and Colter, have also produced higher yields over
that period. Two-row varieties tended to have
lower BSR infection than six-row lines. The most
commonly planted six-row varieties, Colter,
Steptoe, Gustoe, and Gus had 83, 70, 55, and 53
percent BSR infection at KES, respectively. Ten
two-row entries had 12 percent or less BSR
infection at KES. Six entries in this group produced yields in excess of 5,000 lb/acre;
Baronesse, Idagold, C-22, Galena, Chinook, and
78Ab 10274. Although B 1202 had 22 percent
BSR infestation, it yielded 5080 lb/acre. The
highest yielding entry at the irrigated organic soil
site in 1997 was Nebula, a new variety that has
shown less susceptibility to BSR than most
commercially available varieties. BSR infection
was not as severe at this site as at KES, and
traditional 6-row varieties such as Gustoe, Colter,
and Gus did quite well, ranking 2, 3, and 4 in
yield at this site. Average yield at the unirrigated
organic soil site was only 1,210 lb/acre because
of frost and wheatstem maggot damage. The
highest-yielding entries in the trial in 1997 were
two lines that have been less susceptible to BSR,
Gallatin and 78Ab 10274. Steptoe treated with
Vitivax and Steptoe treated with Baytan were
included in all trials. Baytan treatment resulted in
no significant yield increase at any site.
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 1997 included the Western Regional
Spring Barley trial in cooperation with western
states plant breeders, early variety screening of
barley stripe rust (BSR) resistant lines, and a
statewide barley trial. The statewide trial is a
collection of new varieties and promising lines
from public and private breeding programs. The
statewide trial, in cooperation with a number of
Oregon State University (OSU) scientists, was
planted at KES and at two sites in the Lower
Klamath Lake area.

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, 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 barley trials were arranged in a
randomized complete block design with
either three or four replications. Crops at
KES were planted on May 7 and 8. Irrigated
and unirrigated organic soil sites were planted
on May 14 and May 2, respectively. Seed
was planted to a depth of 1 inch. Seeding
rates in OSU statewide trials were 30 seed/
ft'. All other trials had seeding rates of 100
lb/acre. All plots were fertilized with 20 lb N,
12 lb P 2 0 5 , and 9 lb S/acre at time of seeding. Additional fertilizer was broadcast prior
to planting at 80 lb N, 48 lb P,O,, and 35 lb
S/acre. Plots measured 5x 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, percentage of plumps, and
percentage of thins were measured in only
one replication.

Results and Discussion
OSU Spring Barley Trials
Mineral Soil Site
Two-row Varieties tended to have lower BSR
infection than six-row lines. The most commonly
planted six-row varieties, Colter, Steptoe. Gustoe,
and Gus had 83, 70, 55, and 53 percent infection,
respectively (Table 1). Ten entries had 12 percent or
less BSR infection. Six entries in this group produced
yields in excess of 5,000 lb/acre: Baronesse, Idagold,
C-22, Galena, Chinook, and 78Ab 10274.
Baronesse is commonly planted in the area and has
produced high yields in trials at KES and at organic
soil sites for a number of years. Seed availability is
limited for Galena, Idagold and C-22, varieties
produced by Coors. The recently released BSR
resistant variety 78Ab10274 also has very limited
seed supplies. Seed of Chinook may be available in
small quantities, however, it should be noted that this
variety lodged severely in the trial. Crest produced
4,950 lb/acre and only had 8 percent BSR infection.
Crest had 2 percent lodging. Although B 1202 had
22 percent BSR infestation, it yielded 5080 lb/acre.
The commercially available 6-row entries
with the lowest BSR infection were Gallatin and
Nebula with 17 and 27 percent infection, respectively
(Table 1). These varieties produced 5,270 and
4,990 lb/acre, respectively. Stander produced 5,120
lb/acre and had lower BSR infection than most
6-row entries. UC 960 had the lowest level of BSR
infection of any 6-row entry in the trial. It is being
considered for release by UC Davis researchers.
BSR has been an important factor in barley
yield in the region for the past 3 years. Several
varieties, with better resistance to BSR than commonly grown varieties such as Steptoe and Colter,
have also produced higher yields over that period.
Klamath Experiment Station
Spring Barley Variety Screening, 1997
Baronesse has been the leading producer over a
3-year period, followed by Stander, 78Ab 10274,
and Crest (Table 2).
BSR is a changeable organism: resistance
to the disease in one year does not guarantee
resistance in following years. What we currently
have in commercially available spring barley
varieties is best described as a gradient from less
susceptible lines to very susceptible lines. Choosing varieties that have shown less disease expression in the past may result in less disease in
subsequent years. However, vigilant scouting
programs should be followed and application of
foliar fungicides may be necessary until truly
resistant lines are commercially available.
Irrigated Organic Soil Site
The highest yielding entry at this site in
1997 was Nebula, a new variety that has shown
less susceptibility to BSR than most commercially
available varieties (Table 3). BSR infection was
not as severe at this site as at KES, and traditional 6-row varieties such as Gustoe, Colter, and
Gus did quite well, ranking 2, 3, and 4 in yield at
this site. Orca and UC/NK 2867 produced only
slightly lower yields than the traditional lines and
had almost no disease expression. Over the last
two years, the top yielding varieties at this site
were Gus, Colter, Gustoe, and Russell (Table 4).
Colter produced the highest yield at this site over
3 year despite its susceptibility to BSR.
Unirrigated Organic Soil Site
For the third year in a row, a frost in midAugust 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 1997 so data were
collected. The average yield was only 1,210 lb/
acre in 1997 and 1,650 lb/acre in 1996 and
average test weights were 44.8 and 46.9 lb/acre,
respectively (Tables 5 and 6). The highest yielding
entries in the trial in 1997 were two lines that have
been less susceptible to BSR, Gallatin and
78Ab 10274. The second highest yielding entry
was Baronesse. Baronesse was the highest
yielding entry at this site in 1996, producing 2,970
lb/acre, and was the second highest in percentage
of plump kernels.
Steptoe treated with Vitivax and Steptoe
treated with Baytan were included in all trials.
Baytan treatment resulted in no significant yield
increase at any site. Similar inconclusive results
were obtained from field scale and small plot
studies at three sites in the Klamath Basin in both
1996 and 1997. It appears that late season BSR
infestation occurred after the window of protection provided by Baytan had passed in both
years.
Western Regional Spring Barley Nursery
Seven entries were not significantly lower
yielding than WPB-BZ594-19, the highest
yielding entry in the trial. Other high producing
entries include SK CDC Dolly, UT2120, UT
4603, WA 8772-93, SK TR 128, MT
H 18151195, and ID 90321. All of these entries
produced significantly (P = 0.05) higher yields
than Klages and Stander and all except the last
two produced significantly higher yields than
Steptoe. Top yielding varieties over the last two
years include MT H18151195, WA 9792-90,
Stander, ID90241, and BA 2B91-4947. Over a
three-year period, BA 2B91-4947 was the
highest yielding entry.
