Introduction
Spring wheat is grown on approximately 8,500 acres annually in the
Klamath Basin. Soft white (SW) and hard red (HR) selections predominate;
however, interest has grown recently in the hard white (HW) class. In 1994,
spring wheat variety trials were conducted at the KES in cooperation with
Oregon State University and western regional plant breeding and evaluation
programs. Cold-tolerant, short-season cultivars are needed in the Klamath
Basin due to a short growing season with the possibility offrost throughout the
growing season. Entries evaluated in these trials included SW, HW, and HR
selections. Historically, there has been little disease or insect pressure on small
grains in the Klamath Basin. However, the recent introduction ofthe Russian
wheat aphid has altered this situation. Wheat stem maggot is endemic in the
area and generally causes only slight damage at the KES. Under mild winter
and warm spring conditions in 1992 and 1993, significant damage to cereal
crops was experienced, with up to 50 percent of the tillers affected at KES
and with serious crop losses in several commercial fields 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 ofwhich have a fine loamy to sandy texture and are moderately
deep and somewhat poorly drained. All plots were sprinkler irrigated.
All trials were arranged in a randomized complete block design with
three or four replications. Plots at the KES were planted on April 21. Seed
was planted at a depth of 1 inch. The seeding rate for wheat trials was 80 lb/
acre. All plots were fertilized with 100 lb N, 60 lb P 2 0 5 , and 44 lb S/acre at
time of seeding. Plots measured 5 x 20 feet, with 10 rows at 6-inch spacing.

Bromoxynil and MCPA were applied at labeled rates to control broadleaf
weeds. Plots were harvested in late September using a plot combine with a 5foot wide header. Grain yield was recorded for all plots. Test weight was
measured in only one replication.
Results and
Discussion
Western Regional Spring Wheat Nursery
Penawawa was the highest yielding entry in the western regional spring
wheat nursery (Table 1). Penawawa has consistantly been a top yielding
variety for several years and is the highest yielding variety over a three-year
period (Table 2). Centennial, a recently released SW variety, produced
yields which were not significantly different from Penawawa. Further investigation of Centennial is warrented due to its performance in this and other
trials. Other entries with yields not significantly different than Penawawa in
1994 include OR 895181, ID 450, ID 448, SDM 405, and SDM 406.
Alpowa is a recent SW release from Washington State. It produced yields
lower than Penawawa in 1994 and over a three-year period, but more than
the trial average.
The HW line ID 377S was the second highest yielding entry in the trial
over a three-year period. It has good milling and baking quality and is being
considered for release by the University of Idaho.
OSU Hard White Spring Wheat Variety Trial
The highest producing entry in the OSU hard red spring wheat variety
trial in 1994 was SERI 82 (Table 3). This was the only entry in the trial to
produce significantly more grain than Klasic, the HW industry standard.
Other high yielding lines not significantly different from SERI 82 in 1994
included: OR4870453, ID377S, OR918049, OR4870255, and
OR4895181. Both SERI 82 and OR4870453 produced significantly more
grain than Westbred 906R and Westbred 926, the two HR standards included in the trial. SERI 82 has only been in the trial for two years, but over
that period it has produced more grain than any other entry in the trial (Table
4). Other entries which produced significantly more grain than Klasic over
the same two-year period included: OR4870453, OR918049, OR4895181,
126 Klamath Experiment Station
Spring Wheat Variety Screening
0R918050, and 0R918085. Over a three-year period, OR4870453 and
OR4895181 yielded significantly more than Klasic (Table 4). OR 4870279
produced yields equivalent to Klasic in this trial over a three-year period, and
much higher yields in the western regional trial. This HW line has good baking
quality and may be released if yields in other areas of the Pacific Northwest
justify it.
OSU Hard Red Spring Wheat Variety Trial
Standard HR spring wheat varieties in the Klamath Basin are Westbred
906R and Yecora Rojo. Spillman, a recently released variety, is increasing in
acreage. There was not a significant difference in grain yield among these
varieties in the 1994 trial (Table 5). Yields of nine entries, including McKay
and Spillman, were not significantly less than OR 4920002, the highest
yielding entry in the 1994 trial. Yecora Rojo and Klasic reached 50 percent
heading earlier than all other entries in the trial. Over a three-year period, only
0R4870400 produced significantly higher yields than Spillman and McKay,
the two highest yielding standard varieties in the trial (Table 6). Grain baking
quality is an important consideration in the selection of HR wheat varieties.
Further testing examining baking quality oftop yielding entries will be needed
prior to release of these lines.
Soft White Spring Wheat Variety Trial
Centennial was the highest yielding entry in the trial in both 1993 and
1994 (Tables 7 and 8). Centennial is a recent release from the University of
Idaho, which was planted in joint trials at KES and the Intermountain Research and Extension Center from 1989 to 1991. Yields ofthis line were
comparable or superior to all released SW varieties at both locations. This
new SW variety produced significantly more than all other entries in the trial
over that two-year period. Centennial is also an earlier maturing variety. It
reached 50 percent heading earlier than any other entry in the trial in 1994
(Table 7) and was second earliest in 1993. SW wheat varieties have been
slow to mature in the cool fall conditions common in the Klamath Basin. The
development of a earlier maturing, high yielding SW variety should help
Klamath Experiment Station 127

producers who choose to grow this commodity in the Basin. Further plot
scale testing and small field scale testing is warrented and should be undertaken prior to large field scale planting ofthis variety.
OSU State Wide Spring Wheat Variety Trial
Centennial was the highest producing entry in this trial at KES over the last
two years (Table 9). As in the trial mentioned above, Centennial produced
significantly more grain than any other entry in the trial over a two-year
period. The next highest producing group of entries included Owens, a SW
wheat, Klasic, a HW wheat, and Treasure, a SW wheat. This trial was also
established on two organic soil sites in 1994. Centennial was the highest
producing entry at all three sites in 1994 (Table 10). The two triticale entries
in the trial failed to produce grain yields equal to the higher producing SW or
HW entries at any location.
