Spring Small Grains Variety Trials
in the Klamath Basin, 1987
R.L. Dovel, G.E. Carter, and G. Chilcote 1
Introduction
Spring barley, wheat, and oats varieties were evaluated at the Klamath
Experiment Station (KES) in cooperation with plant breeding programs at
Oregon State University, Tulelake Field Station, University of California,
and regional evaluation programs. The various yield trials were conducted
to identify released and soon-to-be released varieties best adapted to the
Klamath Basin and aid in evaluation of germ plasm to be used throughout the
western region. There is little insect or disease pressure imposed on small
grains in the Klamath Basin; however, the high spring winds, short growing
season, and late spring frost typical of the area require the development of
cold tolerant, lodging resistant, short season small grain varieties.
Procedures
Most trials were established at the KES; however, the commercial source
spring wheat and barley trials were established at three sites - the KES on
mineral soil and at two locations on organic soils. All small-grain trials
at the KES were planted on ground previously planted to potatoes. Although
soil type varies at the KES, all have fine loamy to sandy texture and are
moderately deep and somewhat poorly drained. Trials off the station were on
organic soils described as very deep, poorly drained, lake bottom soils.
Both sites are continuously planted to small grains. All plots at the KES
were irrigated, while only one organic soil site was irrigated.
All spring small-grain variety trials were arranged in a randomized
complete block design with four replications. All trials at the KES were
planted between April 27 and 29 using a modified Kincaid planter. Cereals
were planted on the irrigated organic soil site on May 19, while the nonirrigated organic soil site was not planted until June 8. Seed was planted
to a depth of one-inch at a rate of 100 lbs/A. All plots were fertilized
with 100 lbs. N, 60 lbs. P205, and 44 lbs. S at time of seeding. Plots
measured 5 x 20 feet with a row spacing of 6 inches. Bromoxynil was applied
at the labelled rate to control broadleaf weeds.

Although this trial was designed to test the productivity of released
varieties on mineral soils in the Klamath Basin, some promising numbered
varieties were included. The OSU variety OSB 763128 gave the highest yield
over a three-year period. It outyielded Steptoe, the standard variety in
the Klamath Basin, by an average of almost 500 lbs/A. OSB 763128 also
exhibited a higher resistance to lodging than Steptoe (0 and 29 percent
lodging in 1987, respectively). Released varieties which exceeded or
equalled Steptoe over a three-year period included Gustoe, Gus, Blazer, and
Teton. Cougbar, which has been in the study for only two years, looks
promising in the Klamath Basin. It produced an average of over 600 lbs/A
more than Steptoe with only 5 percent lodging in 1987.
Commercial Source Variet/TlialsiTabiell
A reduced number of released varieties of spring barley were planted
at three different sites. The relative performance of the taller varieties,
especially Steptoe and Teton, was better on organic soils compared to the
mineral soil site. In contrast, the shorter varieties, Gustoe and Gus, were
ranked first and second on the mineral soil, but dropped to 10 and 8 on the
irrigated organic soil site and 7 and 8 on the non-irrigated organic soil
site.
Spring Malting Barley Elite Yield Trial (Table 3)
All but one numbered variety outyielded both Morex and Klages and
most showed an improvement over these two standard varieties in lodging
resistance. OSB 783063 demonstrated a yield potential that exceeded that of
Steptoe by 11 percent in 1987. This variety also outyielded Steptoe in
trials planted on the station in 1985 when it exceeded Steptoe by 15 percent.
OSB 783063 may prove to be a useful feed barley for the Klamath Basin even
if it is not accepted as a malting variety.
Early Spring Barley Elite Yield Trial (Ile4)
OSB 783063 grain yields exceeded Steptoe by 22 percent. Other varieties
to outyield Steptoe by more than 15 percent included Mex 793023X-F4K1, OSB
763058, and IBON 82029.
Western Spring Barley Yield Trial (Table 5)
Three lines outyielded Steptoe by over 15 percent, OR 8408, SF 8623, and
SM 8618. Interestingly, OR 8408 was tested in 1985 and yielded only 3 percent more than Steptoe. All three lines appear to be more lodging resistant
than Steptoe.

Commercial Source Spring Wheat Variety Trial - Mineral Soil (Table 6)
The Oregon State University experimental line PC 790647 has been the
highest yielding hard red spring wheat in this study over a three-year
period.. It outyielded Yecoro Rojo, the standard variety in this area, by
over 37 percent. The second highest yielding variety, Sawtell, appears to
have low quality as indicated by test weight and initial protein content
determination. Powell is another variety that may be a good choice for the
Klamath Basin. However, further quality testing is needed to determine if
high yielding lines are of adequate quality to meet market requirements to
qualify for the higher prices currently given for high protein hard red
spring wheat.
The soft white wheats generally outyielded the hard red varieties.
Waverly was the highest-yielding released variety in this trial. It outyielded Fieldwin, the standard white wheat for this area, by over 6 percent.
The highest-yielder in the trial was a Washington numbered variety, WA 6298,
which outyielded Fieldwin by over 13 percent.
Commercial Source Spring Wheat Variety Trial (Table 7)
ORS 8511 was the highest-yielding hard red spring wheat at all three
sites in 1987. However, data on ORS 8511 has been collected at the mineral
soil site for only one year and was not included in the table. Over a twoyear period ORS 8511 was the highest-yielding hard red spring wheat on the
non-irrigated organic soil site and the second-highest yielder on the irrigated organic soil site. Although Sawtell was the highest-yielding hard red
spring wheat, excluding ORS 8511, at all three sites, low quality will
probably prevent the adoption of this variety. Further quality testing is
needed to ascertain if ORS 8511 has the quality required to command the
premium prices obtained by lower-yielding varieties such as Yecoro Rojo and
906R.
Twin appeared to have a distinct yield advantage over the other two
soft white wheats on both organic soil sites. No significant differences in
yield between the three white wheat varieties were observed at the mineral
site.
Intermountain Spring Wheat Variety Trial (Table 8)
This trial was conducted in cooperation with the Tulelake Field Station
and included released and numbered spring wheat varieties currently being
tested in Northern California which were not incorporated into existing
trials on the KES. Spillman was the highest-yielding hard red spring wheat.
It is a quality hard red spring wheat which outyielded 906R, the standard
hard red spring wheat in this trial, by over 21 percent.
This trial included several very promising white wheats including, in
order of yield, Treasure, Discovery, Bliss, Fieldwin, and Blanca.

Hard Red Spring Wheat Elite Variety Trial (Table 9)
The highest-yielding variety, MPC791432, outyielded Yecoro Rojo by over
52 percent. MPC770062 and 16IBWSN83 both outyielded Yecoro Rojo by more
than 42 percent. Although there is only one year of data on these three
lines, the yields are impressive. Further yield testing and quality
analysis are needed to ascertain if these lines are capable of consistently
producing high yields of quality wheat in the Klamath Basin.
Western Regional Spring Wheat Trial (Table 10)
Spillman, which was the highest-yielding hard red winter wheat in the
Intermountain Spring Wheat Trial, was the seventh-highest hard red spring
wheat in this study. The lines outyielding Spillman, in order of yield,
were ID 365, OR 8511, UT 461941, ID 303, ORS 8512, and ID 366.
Spring Oats Variety Trial (Table 11)
In this trial the three leading lines over a three year period were
numbered lines. In order of yield they were WA6160, 76AB6843, and WA6166.
Appaloosa and Cayuse were fourth and fifth, respectively, and are the main
cultivars currently planted in the Klamath Basin.
Uniform Northwestern States Oat Trial (Table 12)
The highest-yielding varieties in this trial were Steele and Riel,
yielding over 30 and 24 percent more than Cayuse, respectively. These
varieties also showed a marked improvement over Appaloosa in lodging
resistance. However, both Steele and Riel had lower test weights than other
high-yielding varieties in the trial. Further testing is needed to substantiate the yield potential, lodging resistance, and quality of these promising lines in the Klamath Basin.
