Spring Small Grain Variety Trials
in the Klamath Basin, 1988
R.L. Dovel and G. Chilcotel
INTRODUCTION
In 1988 small grain variety trials were conducted at the Klamath
Experiment Station in cooperation with plant breeding and evaluation
programs at Oregon State University, Washington State University, the
Tulelake Field Station (University of California at Davis), and several
Western Region evaluation programs. Cold-tolerant, short-season cultivars
are needed in the Klamath Basin due to a short growing season with the

general there is little disease or insect pressure on small grains in the
Klamath Basin. However, the introduction of the Russian Wheat Aphid could
greatly alter that situation.
PROCEDURES
Most trials were established at the KES; however, an alternative site
on organic soil was also used for several trials. All small-grain trials at
the KES were planted 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. All plots at both sites were
sprinkler 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. All plots at the organic soil site were planted on May 26.
Seed was planted to a depth of one inch. The seeding rate for wheat trials
was 80 lbs/A while the barley and oat trials received 100 lbs/A. All plots
were fertilized with 100 lbs N, 60 lbs P205, and 44 lbs S/A at time of
seeding. Plots measured 5 x 20 feet with a row spacing of six inches.
Bromoxynil and MCPA were applied at labeled rates to control broadleaf
weeds. Chemical weed control at the organic soil site was achieved using a
mixture of 2,4-D and Banvel.

RESULTS AND DISCUSSION
Comparison of Barley Varieties At Two Locations
Only one released variety, Gustoe, and one numbered line, OSB 783063,
had significantly higher yields than Steptoe on the mineral soil site (Table
1). Two lines, OSB 74289-5K and OSB 77289-5W, had higher yields than Steptoe on the organic soil site. Other released varieties which had yields
comparable to Steptoe at both sites included Advance, Blazer, Gus, Micah,
and Fiesta.
1988 Intermountain Regional Spring Barley Trial
Steptoe continues to be one of the highest-yielding spring barley varieties for this area. Four varieties (Columbia, Gustoe, ORSM 8423, and OSB
783063) had significantly higher yields than Steptoe, which yielded 5333
All these varieties had 3 percent or less lodging, comlbs/A (Table 2).
pared to 68 percent lodging in Steptoe. The greater yields and increased
lodging resistance of the two released cultivars mentioned above should
encourage their further adoption as replacements for Steptoe in the area.
ORSM 8423 and OSB 783063 have been included in the Spring Malting Barley
Elite Yield trial for two years and ranked first and fourth in total yield

further to determine if their release is warranted.
Spring Malting Barley Elite Yield Trial
This was the second year for this trial to be conducted. High-yielding
malt-quality barley varieties which are better adapted to the Klamath Basin
are needed. Four varieties included in this trial are under consideration
as malting varieties and have passed various levels of malt-quality testing.
The two-row variety, ORSM 8408, has been approved for plant scale testing.
Yields of this variety have been comparable to Klages at KES and in statehowever, ORSM 8408 is much more resistant to lodging than
wide testing;
Another two-row line, ORSM 8411, has a yield potential

similar to Klages, but is no more resistant to lodging than Klages (Table
3). ORSM 8411 has passed pilot scale brewing and is being considered for
plant scale testing. The short-strawed two-row line, ORSM 8623, has shown
high malt quality and has passed pilot scale malting tests. Yields are
superior to Klages and no lodging has been seen in this line at the KES.
The highest yielding line at KES, 2860254, averaged 7,197 lbs/A over a twoyear period. This is roughly equivalent to Steptoe, which yielded 6,998
lbs/A over the same period. There has been some objection to this line due
to excessive thins. However, this is a longer-season variety and management
may be the cause of the high percentage of thins. The excellent yields
certainly warrant further investigation.
Washington Source Spring Barley trials
This was the first year that Washington source material has been evaluated at the KES aside from the regional trials. This is a cooperative
effort of OSU and WSU. The major breeding emphasis at OSU will be on winter
barley and the major emphasis at WSU will be on spring barley. Three 6-row
WSU lines exhibited high yields (Table 4). WA007588 was slightly lower in
66
yield than WA007573 and WA007572, but had a higher test and very few thins.
The outstanding 2-row selection was WA007345 (Table 5). It produced the
highest yield with high test weight and a low percentage of thins.

Discovery yielded significantly
It is
higher than all other hard red varieties at the organic soil site. obvious that the higher-yielding hard red varieties included in this trial
could be viable alternatives to Yecoro Rojo provided quality of these
varieties is equivalent to Yecoro Rojo.
1988 Intermountain Regional Spring Wheat Variety Trial
The top three yielders in this trial were OSU numbered varieties - one
hard white wheat and two hard red varieties (Table 7). Demand for hard
white wheats for export to the Asian Rim countries has increased in recent
years. Klasic is the standard hard white variety currently being exported.
The variety ORS 8413 was the highest yielder in the trial, more than
doubling the yield of Klasic. Another OSU hard white variety, PC 790647,
substantially outyielded Klasic. Milling and bread-making quality of these
two varieties will be analyzed and compared to Klasic to evaluate their
potential to replace Klasic in the Intermountain Region.
The two varieties OSR 8509 and ORS 8511 were the highest-yielding hard
red varieties in the trial (Table 7), outyielding the current standard
varieties in the area, Yecoro Rojo and Westbred 906R. ORS 8509 and ORS 8511
were also top yielders in the variety trial at the Tulelake Field Station.
Further quality testing is needed to determine if these two promising
varieties have quality to compete with current varieties.
1988 Western Regional Spring Wheat Trial
The highest-yielding line in 1988 was a soft white line from Idaho, ID
372 (Table 8). This was its first year in the regional trial. The three
next highest-yielding lines were hard red varieties, WA 7075, ID 366, and UT
884. ID 366 was also in the 1987 regional trial and yielded similarly to
Spillman, a promising new hard red spring wheat. Further yield and quality
testing is needed to fully assess the value of these promising lines to the
Klamath Basin.
1988 Hard Red Sprino Wheat Variety Trial
Promising lines based on a two-year average include ORS 8518, ORS 8509,
ORS 8511, and ORS 8512. All of these lines yielded an average of over 900
67
lbs/A more than 906R and over 1,200 lbs/A more than Yecoro Rojo over that
period (Table 9). Due to the importance of grain quality in the acceptance
of hard red spring wheats, further testing of grain quality will be required
to assess the suitability of these promising lines for commercial production. The only released variety to place in the top five yielding lines in
the 1988 trial was Borah. It has consistently outyielded both Yecoro Rojo
and 906R in test plots for several years; however, adoption of this variety
by producers has been minimal due to the failure of field-scale plantings to
produce the high yields experienced in plot trials.
1988 Uniform Northwestern States Oat Nursery
Yields were very low this year due to frost and bird damage. Lodging
was also very severe. Due to problems with lodging in oats, short-statured
varieties are of special interest. In 1987 two semi-dwarf oat varieties,
Riel and Steele, were the top yielders in this trial, yielding 24 and 30
percent more than Cayuse, respectively. Both Riel and Steele had slightly
higher yields than Cayuse in 1988 (Table 10); however, the difference was
not significant. Cayuse had 58 percent lodging in 1988 compared to no
lodging for either Riel or Steele. The shortest variety, NPB 86803, had the
highest yield; however, this was the first year that NPB 86803 has been in
the trial and further evaluation is needed to determine its adaptation to'
the Klamath Basin.
