Wheat and Barley Variety Screening
in the Klamath Basin, 2007
Richard J. Roseberg and Jim E. Smith1
Introduction
Grain is produced on about 100,000 acres in the Klamath Basin and 60,000 acres
within the Klamath Reclamation Project. Susceptibility to late spring frosts has
historically limited winter cereal production and spring cereals have accounted for the
majority of production. Starting in 2003, a significant shift to production of hard red
winter wheat was observed. With few late spring frosts and frost-free summers, most of
the winter wheat crops produced reasonably good yield and quality in the past few years.
Klamath Basin Research and Extension Center (KBREC) cereal variety
evaluation efforts have focused on spring cereal varieties in the past, but with the
increased acreage of commercial winter wheat, and grower requests for more winter
wheat information, we began planting winter wheat trials at the station in the fall of 2004.
While the first year (2004-05) included only the OSU Elite Winter Wheat Trial, in 200506 and 2006-07 we also planted the Western Regional Soft Winter Wheat and Hard
Winter Wheat trials on the KBREC site mineral soil.
In 2007, small grain variety trials were conducted on-site at KBREC on a mineral
soil, and at a Lower Klamath Lake (LKL) site on a silty clay loam muck (high organic
matter) soil. The Western Regional Soft Spring Wheat Trial and the Hard Spring Wheat
Trial where planted at both the KBREC and LKL sites. The Western Regional Barley
Trial and the Oregon State University (OSU) Elite Spring Wheat Trial were only planted
at the KBREC site. The Western Regional Soft Winter Wheat Trial and Hard Winter
Wheat Trial, along with the OSU Elite Winter Wheat Trial, were planted only at the
KBREC site as well.
Procedures
KBREC Site
KBREC small grain variety trials were conducted on Poe fine sandy loam soil
following 2006 potato experiments. All trials were arranged in a randomized complete
block design with four replications, except for the OSU Elite Spring Wheat Trial and the
OSU Elite Winter Wheat Trial, which had three replications each. Seed was planted one
inch deep at 30 seeds/ft2 with a Kincaid (Kincaid Equipment Manufacturing) plot planter

on October 3, 2006 for the winter wheat trials, and on April 20, 2007 for the spring trials.
The plots were 20 by 4.5 ft, (9 rows at 6-inch spacing), with a harvested area of 14.5 by
4.5 ft.
All winter and spring grain plots were fertilized with 50 lb/acre N, 63 lb/acre
P2O5, and 41 lb/acre S banded at planting (applying 16-20-0-13 fertilizer at 310 lb/acre).
On April 16, the winter wheat trial area was treated with Weedar® 64 (2,4-D amine,
Nufarm Americas Inc.) herbicide at 1.5 pint/ac (0.7 lb ae/ac) tank-mixed with Solution 32
to apply 50 lb N/ac using a conventional ground sprayer. An additional 60 lb/acre N was
applied to the winter wheat area as Solution 32 on May 24 through the irrigation water.
In the spring grain trial area, we applied a tank-mix of Weedar® 64 (2,4-D amine, Nufarm
Americas Inc.) at 2.0 pint/ac (0.9 lb ae/ac) and Solution 32 to apply 50 lb N/ac on May 24
using a conventional ground sprayer.
Solid-set sprinklers arranged in a 40- by 40-ft pattern were used for irrigation.
Crop water use estimates from the KBREC Agricultural Meteorological (AgriMet)
weather station were used to apply irrigation to meet crop needs. The spring barley trial
area received a total of 12.6 inches of irrigation during the season, applied on 15
occasions. The spring wheat trial area received a total of 16.9 inches of irrigation during
the season, applied on 20 occasions. The winter wheat trial area received a total of 7.7
inches of irrigation during the season, applied on 7 occasions. In addition to irrigation,
rainfall totaled 0.73 inch in April, 0.24 inch in May, 0.44 inch in June, 0.57 inch in July,
and 0.18 inch in August. Plots were harvested using a Hege (Hans-Ulrich Hege) plot
harvester with a 4.5-ft-wide header. The OSU Elite Winter Wheat Trial and the Western
Regional Hard Winter Wheat Trial were harvested on August 24. The Western Regional
Soft Winter Wheat Trial was harvested on August 29. The four spring barley and wheat
variety trials were harvested on September 6 & 7.
LKL Site
LKL spring grain variety trials were conducted on Algoma silt loam soil in a
continuous grain rotation. The field was flooded during the winter to replenish moisture
to the entire soil profile. Both trials were arranged in a randomized complete block
design with four replications. Seed was planted with a Kincaid plot planter as was done
at the KBREC site (above) on May 14, 2007.
All plots were fertilized with 50 lb/acre N shanked in before planting as
anhydrous ammonia, followed by 50 lb/acre N, 63 lb/acre P2O5, and 41 lb/acre S banded
at planting (applying 16-20-0-13 fertilizer at 310 lb/acre). The plots were irrigated by the
grower during the season with the overhead linear move system used for the entire field
(several hundred acres), based on his judgment of water need. Plots were harvested on
September 21 with a Hege plot harvester as was done at the KBREC site.
KBREC and LKL Sites
Due to personnel issues at KBREC, grain harvested from all plots was shipped to
the OSU wheat breeding program in Corvallis for cleaning and analysis in 2007, except
for the barley trial, which was cleaned and analyzed at KBREC. Unfortunately, the two
trials grown at the LKL site (Western Regional Soft Spring Wheat Trial and the Western

Regional Hard Spring Wheat Trial) were accidentally discarded by student employees in
Corvallis before seed cleaning; therefore yield calculation was not possible.
For the trials grown at the KBREC site, grain yield and test weight were measured
for all trials except the two Western Regional Winter Wheat trials, where only seed yield
was measured. For the spring barley trial, percent plumps (percent above 6/64 and 5.5/64
sieves) and thins (pan) were measured in addition to seed yield and test weight. Lodging
percentage was minimal in all trials in 2007. Plant height and maturity (date of 50
percent heading) were not recorded.
All measured parameters were analyzed statistically using SAS® for Windows,
Release 9.1 (SAS Institute, Inc.) software. Treatment significance was based on the F
test at the P=0.05 level. If this analysis indicated significant treatment effects, least
significant difference (LSD) values were calculated based on the student’s t test at the 5
percent level.
Results and Discussion
Soil moisture was good during seedbed preparation, and resulting germination
and stand density were good. There was good availability of irrigation water, lack of
frost, and relatively few hot days during the season. However, weed control was slightly
less than ideal, probably due to use of 2,4-D only. These factors contributed to fair yields
in 2007. By comparing yields of check varieties over the years, we observed several
trends, including: spring barleys generally yielded better in 2007 than 2006; spring
wheats generally yielded less in 2007 than in 2006, and winter wheats were mixed, some
were better in 2006, some in 2007. In most cases for all small grain trials, yields were
greater in 2005 than either 2006 or 2007. More details and year-to-year comparisons are
described below.
Western Regional Spring Barley Variety Trial
Forty entries were included in the 2007 trial, planted at the KBREC site only.
This trial included 17 feed entries (varieties or selections), 15 malting entries, and 8
entries that could be used for either feed or malting. Yields ranged from 3,780 to 6,040
lb/ac with a mean of 5,020 lb/ac (Table 1). These yields were slightly higher than those
observed in the comparable 2006 trial.
Bushel (bu) weights were greater than the 48 lb/bu industry standard for all
entries, indicating good moisture, fertility, and weather conditions during the seed-filling
phase. Only two of the entries had bushel weights below 50 lb/bu. While the overall
mean bushel weight in 2007 was the same as in 2006, the percent of seed retained on the
6/64 screen (the plumpest seed) was greater in 2007, in excess of 98% for all entries.
Multiple-year yield means for all entries that were planted in the 2005, 2006, and
2007 trials at KBREC were calculated (Table 2). Twelve entries were planted all three
years, including five named varieties and seven numbered entries. For these twelve
entries, overall mean yields were greatest in 2005, followed by 2007, with 2006 yields
the lowest. However, some individual entries did not follow this pattern. The yields of
01Ab10062, 02WNZ-1821, and UT99B1670-3458 were greater in 2006 than in 2007.
The yield of Morex was greater in 2007 than either 2005 or 2006.

Individually, feed types Steptoe and Baronesse continued to perform well over
time, with both finishing among the top three in yield for both the 2-year and 3-year
means. Among numbered entries, the malting type 99NZ102 did very well, finishing
second in yield over the 3-year mean, and fourth for the 2-year mean.
Western Regional Soft Spring Wheat Variety Trial
Four standard named varieties and seven numbered selections were included in
both the KBREC and LKL trials in 2006. All were soft white spring types. At the
KBREC site, yields ranged from 4,826 to 5,685 lb/acre, with a mean of 5,292 lb/acre
(Table 3). Yield differences were not statistically significant at the P=0.05 level. As in
2006, Alturas was among the highest yielding entries. Unlike 2006, Nick and Louise had
among the lowest yields in 2007.
Differences in bushel weight were statistically significant. Overall bushel weights
in 2007 were lower than in 2006 or 2005, with a mean of 59.9 lb/bu. Top entries
included Alpowa, ID0669, ID0630, IDO668, and Alturas. As in 2006, Alturas, IDO630
and IDO669 had very good combinations of yield and bushel weight.
Multiple-year yield means for all soft white spring wheat entries that were planted
in the 2005-2007 trials at KBREC were calculated (Table 4). As noted above, 2005 was
a good year for small grains, and the 2005 yield was greater than either the 2006 or 2007
yields for all six entries that were planted all three years. Of the nine entries that were
planted in both 2006 and 2007, most had a higher yield in 2006. Alturas continued to do
well over time, with both the greatest two-year and three-year yield.
Western Regional Hard Spring Wheat Variety Trial
This trial evaluated five hard white spring (HWS) and ten hard red spring (HRS)
wheat experimental lines and named varieties at both the KBREC and LKL sites.
Differences in yield were statistically significant at the P=0.05 level. Total yields at the
KBREC site ranged from 3,392 to 5,646 lb/acre, with a mean of 4,786 lb/acre (Table 5).
HRS and HWS varieties were both represented among the highest- and lowest-yielding
entries. Overall yields were somewhat lower than in 2006, but were not far below the
long-term average, as described above.
Differences in bushel weight were statistically significant. The overall mean
bushel weight was equal to the 60.0 lb/bu industry standard, but were lower than those
observed in 2006, when mean bushel weight was very high (63.3 lb/bu). Of the entries
planted in 2005, 2006, and 2007, only IDO377S was among the highest in bushel weight
all three years (2nd highest in 2005, and tied for 3rd in 2006, and 4th in 2007). The five
highest bushel weights were HRS varieties in 2007, nearly the opposite trend observed in
2006.
In the multiple-year rankings, only four entries were grown in all three years
(Table 8). IDO377S had the second-highest mean yield for the three years. In previous
reports, we noted that IDO377S had the highest three-year mean yield for previous threeyear comparisons (2002-2004, 2003-2005 and 2004-2006). This consistently excellent
performance is worth noting, especially since it was not the highest yielding variety in
any of the individual years.

OSU Elite Spring Wheat Variety Trial
Thirty entries were planted in this trial at the KBREC site only, including 16
named varieties and 14 experimental lines. Yields ranged from 3,594 to 5,772 lb/acre,
with a mean of 4,650 lb/acre (Table 7). Yields were somewhat lower overall in 2007
than a similar trial in 2006. Yield and bushel weight differences between varieties were
both statistically significant. Bushel weights ranged from 57.1 to 61.1 lb/bu, with a mean
of 59.6 lb/bu. The lowest value was equal to that observed in 2006, but the trial mean
and highest values were higher than observed in 2006.
Western Regional Soft Winter Wheat Variety Trial
Thirty-five entries, including four named varieties and 31 experimental lines,
were planted in the trial at the KBREC site only. Differences between varieties were
statistically significant for yield. Bushel weight was not measured by staff in Corvallis.
Yields ranged from 963 to 5,469 lb/acre, with a mean of 3,194 lb/acre (Table 8). Yields
for this trial were lower in 2007 than 2006, possibly due to the trial location having a
surprisingly large quackgrass infestation. Unlike 2006, when the decades-old ‘Stephens’
variety had the highest yield, in 2007 the only named variety in the top half of entries was
Brundage96, which had the sixth highest yield.
Western Regional Hard Winter Wheat Variety Trial
The Western Regional Hard Winter Wheat Trial was planted at the KBREC site
only. Unlike 2006, when this trial had only three entries, in 2007 this trial had 26 entries,
including three named varieties and 23 experimental lines. Yields ranged from 574 to
5,372 lb/acre, with a mean of 3,742 lb/acre (Table 9). Not surprisingly with the
dramatically increased number of entries, both the lowest and highest yields were more
extreme in 2007 compared to 2006. Bushel weight was not measured by staff in
Corvallis. Yield differences between varieties were statistically significant. Mean yield
of this trial was slightly higher than the mean of the Western Regional Soft Winter Wheat
Trial. Comparing results with the prior year, the yield of Finley was slightly higher in
2007, but the yields of Boundary and Kharkof were quite a bit lower in 2007 than 2006.
OSU Elite Winter Wheat Variety Trial
After an absence of an elite winter wheat trial for many years here, we began
planting Dr. Jim Peterson’s OSU Elite Winter Wheat Trial in 2004-05 due to growers’
increased interest in winter wheat information. We repeated this trial in 2005-06 and
2006-07 using Dr. Peterson’s updated entry list.
Thirty-seven entries, including 16 named varieties and 21 experimental lines,
were planted in the trial at the KBREC site only. Of these, four entries were club types
and 33 were soft white types. Yield and bushel weight differences between varieties
were both statistically significant. Yields ranged from 2,826 to 5,886 lb/acre, with a
mean of 4,098 lb/care (Table 10). These yields were somewhat higher in 2007 compared
to this trial in 2006. It is interesting that ORSS-1757 and ORH010085 had the lowest and
third-lowest yields in 2007, whereas they were among the top yields in 2006. As was

true in 2006, all bushel weights were below the industry standard of 60 lb/bu in 2007.
They ranged from 52.9 to 58.5 lb/bu, with a mean of 55.7 lb/bu. Bushel weights overall
were lower than the previous year. This continues a trend where bushel weights of winter
wheats tend to be lower than spring wheats in KBREC trials.
Using data from the 2004-05, 2005-06, and 2007 OSU Elite Winter Wheat trials,
as well as the 2005-06 and 2006-07 Western Regional trials, we can compare multipleyear yield means for 38 named and experimental winter wheat varieties (Table 11). As
noted previously, yields were higher in 2005 than for the other two years. For entries that
were planted all three years, yields were higher in 2007 for some, but were higher in 2006
for others. Of the 16 named varieties, eight had greater yields in 2006 than in 2007. Of
the 18 entries that were in the trials for the past three years, only Brundage96 (1st) and
Stephens (5th) were among the top third in 3-year mean yield.
Summary
The Western Regional Spring Barley and OSU Elite Winter Wheat trials
produced generally higher yields in 2007 than in 2006, the Western Regional Hard
Winter Wheat Trial was somewhat similar between years, and the remaining trials
produced generally lower yields in 2007 than in 2006. Even so, the yields in 2007 were
only slightly below the long-term trial average for this location. It is clear that
unexpected growth of quackgrass in the winter trial area contributed to reduced yields in
some cases. Unfortunately, due to the accidental loss of data from the LKL site, we
cannot compare the results between locations for the Western Regional Soft Spring
Wheat and the Western Regional Hard Spring Wheat trials.
Crop rotation has some influence on the results of these trials and with grain
production in the Klamath Basin in general. Spring grains can easily follow potatoes
grown the previous year, benefiting from typical potato management such as high rates of
fertilization and common use of fumigants, which also reduce weed seeds. Even where
spring grain follows grain the year before, spring moisture, tillage, and use of grain
herbicides often results in good stands with low weed pressure levels. Winter grains,
however, generally follow either a shorter season crop such as grain or canola, or at times
it can follow a forage crop such as alfalfa. To follow alfalfa, however, generally means
not taking a final cutting in September, spraying the alfalfa with herbicide, extensive
tillage, or some combination of the three, all during a time of year when irrigation water
may be less available, which can make tillage more difficult and timely germination more
problematic. With these rotations, the potential for weed infestation is also greater than
following potatoes where fumigants or herbicides are used, or following grain where
additional time between crops can be used in tillage, herbicide application, or both to
reduce weed pressure. Therefore, except where rotations and low weed pressures make it
feasible, it is often easier and more economical to simply grow spring grains in rotation
with potatoes or spring grains, rather than trying to prepare and grow fall-planted grains.
