Wheat and Barley Variety Screening
in the Klamath Basin, 2006
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 a frost-free summer in 2006,
most of the winter wheat crops produced reasonably good yield and quality.
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 entries, in 200506 we also planted the Western Regional Soft Winter Wheat and Hard Winter Wheat
Trials at the KBREC site.
In 2006, 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 Spring Barley Trial, Soft Spring Wheat Trial, and
Hard Spring Wheat Trial where planted at both the KBREC and LKL sites. The Oregon
State University (OSU) Elite Spring Wheat Trial was also planted at both sites. The
Western Regional Soft Winter Wheat Trial and Hard Winter Wheat Trial, as well as the
OSU Elite Winter Wheat Trial and Winter Barley Trial, were planted only at the KBREC
site.
Procedures
KBREC Site
KBREC spring small grain variety trials were conducted on Poe fine sandy loam
soil following 2005 potato experiments. The winter wheat trials followed teff that was
interseeded into winter triticale in 2005. 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 September 22 and 26, 2005 for the winter wheat trials, and on April 19
and 20, 2006 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 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). In the winter wheat
trial area, an additional 50 lb/acre N was applied as Solution 32 on May 16 with a
conventional ground sprayer in a tank mix with the premixed broadleaf herbicide
Weedmaster® (dicamba + 2,4-D amine, BASF) at 2.0 pint/ac, thus applying dicamba at
0.25 lb ai/ac plus 2,4-D at 0.72 lb ae/ac. In the spring grain trial area, an additional 50
lb/acre N was applied as Solution 32 on June 5 with a conventional ground sprayer in a
tank mix with Weedar® 64 (2,4-D amine, Nufarm Americas Inc.) at 2.0 pint/ac, thus
applying 0.9 lb ae/ac 2,4-D.
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 12.0 inches of irrigation during the season, applied on 14
occasions. The spring wheat trial areas received a total of 13.8 inches of irrigation during
the season, applied on 15 occasions. The winter wheat trial area received a total of 6.2
inches of irrigation during the season, applied on 6 occasions. In addition to irrigation,
rainfall totaled 0.89 inch in April, 0.11 inch in May, 0.35 inch in June, 0.01 inch in July,
and 0.28 inch in August. Plots were harvested using a Hege (Hans-Ulrich Hege) plot
harvester with a 4.5-ft-wide header on August 21-23 for all trials.
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. All trials were arranged in a randomized complete block design
with four replications, except for the OSU Elite Spring Wheat Trail, which had three
replications. Seed was planted with a Kincaid plot planter as was done at the KBREC
site (above) on April 19 and 20, 2006.
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 320 lb/acre). Due to a misunderstanding
with the grower, broadleaf post-emergence herbicides were not applied in 2006, unlike
our normal practice on variety trial research plots. 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
12 with a Hege plot harvester as was done at the KBREC site. Because of the herbicide
misunderstanding, weed pressure at the LKL site was much higher than normal. As a
result, it was decided that only the Western Regional Spring Barley Trial would be
harvested, as the wheat trials were too compromised by excessive weed pressure to obtain
meaningful data at the LKL site.

20 06 Annual Report
KBREC and LKL Sites
For both sites, data collected included grain yield and test weight. Lodging
percentage was minimal in all trials. Plant height and maturity (date of 50 percent
heading) were not recorded. For the barley trials, percent plumps (percent above 6/64 and
5.5/64 sieves) and thins (pan) were also measured. For all trials, grain moisture was
measured and used to adjust yield to industry standards (10% percent moisture by
weight).
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. Good availability of irrigation water, lack of frost,
relatively few hot days during the season, and good weed control at the KBREC site all
contributed to fair yields in 2006. At the KBREC site yields for the Western Regional
Spring Barley Trial and the Western Regional Soft Spring Wheat Trial were quite a bit
lower for all entries in 2006 compared to 2005. However, overall yields for the Western
Regional Hard Spring Wheat Trial were only slightly lower in 2006 compared to 2005,
with a few entries exhibiting higher yields in 2006. Looking at check varieties that have
been planted in these trials for many years, in general the 2006 wheat and barley yields
were usually slightly lower than the long-term average, but were not close to the poorest
trial yields observed in some prior years. The relatively low yields in the winter wheat
trials at KBREC in 2006 were probably due to less-than-ideal irrigation management and
location in a part of the field with generally poorer soil. At the LKL site initial irrigation
was delayed due to equipment repairs. This, combined with unusually high weed
pressure, resulted in yields that were quite a bit lower in 2006 than in 2005 at that site. As
such, LKL yields reported here should be viewed with caution.
Western Regional Spring Barley Variety Trial
Thirty-six entries were included in the 2006 trial. This trial included 16 feed
varieties, 13 malting varieties (or numbered selections), and 7 varieties that could be used
for both feed or malting. At the KBREC site, yields ranged from 3,580 to 5,780 lb/acre
with a mean of 4,534 lb/acre (Table 1). At the LKL site, yields ranged from 2,440 to
4,810 lb/acre with a mean of 3,840 lb/acre (Table 2). Yields at the KBREC site were
probably higher than the LKL site in 2006 due to more timely early irrigation at KBREC
and unusually high weed pressure at LKL, as mentioned above.
Comparing results for the two sites demonstrated how some varieties are bettersuited for more specific growing conditions, while others are more widely adapted to
dissimilar growing environments. For example, Baronesse, 01ST1758, and 01NZ706
yielded very well at both sites relative to other entries, while 01ID435H and ND21863
had low yield at both sites. Most varieties did somewhat better at one site or the other, but
a few had radically different yields at the two sites. For example, WA 7330-00 had the 7th
______________________________________________________________________________

highest yield in the mineral soil, but it had the 3rd lowest yield in the organic soil.
Similarly, 02WNZ-1821 had the 5th highest yield in the mineral soil, but it had the 6th
lowest yield in the organic soil. Conversely, Harrington had the 4th highest yield in the
organic soil, but it had the 8th lowest yield in the mineral soil. Similarly, 01Ab110055 had
the 8th highest yield in the organic soil, but it had the 6th lowest yield in the mineral soil,
and YU501-312 had the 6th highest yield in the organic soil, but it had the 7th lowest yield
in the mineral soil.
Bushel (bu) weights were greater than the 48 lb/bu industry standard for all
entries at both sites, indicating good moisture, fertility, and weather conditions during the
seed-filling phase. This was especially true at the KBREC site, where the percent of seed
retained on the 6/64 screen (the plumpest seed) was very high (trial mean of 95.1%,
Table 1). The trial mean of seed retained on the 6/64 screen at the LKL site was 92.4%,
still an acceptable value. This pattern is the opposite of what was observed in 2005,
where the percent of seed retained on the 6/64 screen was 7.0% higher at the LKL site.
Multiple-year yield means for all entries that were planted in the 2004, 2005, and
2006 trials at KBREC were calculated (Table 3). Nine varieties were planted all three
years, including five named varieties and four numbered entries. Interestingly, the
excellent 2004 growing conditions were reflected in dramatically higher yields in 2004
for the five named varieties, but not for the four numbered entries. For those four
numbered entries, yields were highest in 2005. Yields in 2006 were lower than 2004,
2005, or both for all nine entries. The named varieties Baronesse, Stander, and Steptoe
had the highest 3-yr mean yields, but only Steptoe was among the leaders for two-year
mean yield (2005-2006), suggesting that Baronesse and Stander have the potential to
excel under excellent conditions such as occurred in 2004, but are not necessarily better
than some newer experimental varieties under less-than ideal conditions.
OSU Elite Winter Barley Variety Trial
This trial was planted only at the KBREC site. Winter barley is not planted on
many acres in the Klamath Basin, but because a winter barley trial had not been planted
at KBREC since the 1992-93 season, we agreed to plant a small trial after consultation
with OSU barley breeder Dr. Pat Hayes and local grain industry staff.
There were four named barley varieties and two experimental lines (Kab47 and
Stab113) in this trial. Recently, Stab113 was licensed to AgriSource and sold as the
variety “Maja”. Yields ranged from 3,460 to 4,010 lb/acre, with a mean of 3,785 lb/acre,
but there was no statistical difference in yield between any of the varieties (Table 4).
Unlike the regional spring barley trials, the only factor we measured with statistically
significant differences between treatments was bushel weight. Bushel weights were well
above the 48 lb/bu industry standard for all entries. The percent of seed retained on the
6/64 screen was not very high (trial mean of 76.3%). Overall, the performance of these
winter barley varieties was not particularly impressive.
Western Regional Soft Spring Wheat Variety Trial
Four standard named varieties and 16 numbered selections were included in both
the KBREC and LKL trials in 2006. Eighteen of the entries were soft white spring types,
and two were club types. At the KBREC site, yields ranged from 4,140 to 6,800 lb/acre,
______________________________________________________________________________
Klamath Basin Research and Extension Center
Wheat and Barley Variety Screening in the Klamath Basin, 2006 Page 4
Research in the Klamath Basin
20 06 Annual Report
with a mean of 5,395 lb/acre (Table 5). Yield differences were not statistically significant
at the P=0.05 level. Yields in 2006 were much lower than in 2005 overall. The three
highest-yielding entries were named varieties (Alturas, Nick, and Louise). The LKL site
was not harvested due to excessive weed pressure, as described above.
Differences in bushel weight were statistically significant. At the KBREC site, all
but two entries were above the 60 lb/bu industry standard. Overall bushel weights in 2006
were lower than in 2005, with a mean of 61.8 lb/bu. Top entries included Alpowa,
ID0645, ID0630, Alturas, and ID0629. Alturas had the best overall combination of yield
and bushel weight, ranking first in yield and fourth in bushel weight.
Multiple-year yield means for all soft white spring wheat entries that were planted
in the 2004-2006 trials at KBREC were calculated, although only two entries were
planted all three years (Table 6). Of the eleven varieties that were planted in both 2005
and 2006, every single one had a higher yield in 2005. Over those two years, Alturas and
Alpowa had higher average yields than the other entries.
Western Regional Hard Spring Wheat Variety Trial
This trial evaluated twelve 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 not statistically significant. Total yields at the KBREC site
ranged from 4,860 to 7140 lb/acre, with a mean of 5,965 lb/acre (Table 7). HRS and
HWS varieties were both represented among the highest- and lowest-yielding entries.
Top entries included ID0647, WQL9HDALP, OR4990114, IDO377S, and IDO628.
Overall yields were somewhat lower than in 2005, but were not far below the long-term
average, as described above. The trial at the LKL site was not harvested due to unusually
heavy weed pressure, as described above.
Differences in bushel weight were statistically significant. Bushel weights were
above the industry standard of 60 lb/bu for all entries at KBREC, with a mean of 63.3
lb/bu. Although this was well above the standard, the mean was 1.0 lb/bu lower in 2006
than in 2005. Of the entries planted in both 2005 and 2006, only IDO377S was among the
highest bushel in weight both years (2nd highest in 2005 and tied for 3rd in 2006). Four of
the top five highest bushel weights were HWS varieties, but the HWS and HRS were
fairly evenly distributed throughout the remainder of the ranking.
In the multiple-year rankings, six varieties were grown in the three-year period
(Table 8). IDO377S had the highest mean yield for the three years, just as it also had the
highest three-year yield for previous three-year comparisons (2002-2004 and 2003-2005).
This consistently excellent performance is worth noting, especially since it was not the
highest yielding variety in any of the individual years. Other varieties followed a similar
pattern in their ranking regardless of whether the comparison was over two or three years,
suggesting their likely long-term relative performance under these conditions is fairly
predictable.
OSU Elite Spring Wheat Variety Trial
Thirty-four entries were planted in this trial, including 19 named varieties and 15
experimental lines. At the KBREC site, yields ranged from 4,278 to 7,080 lb/acre, with a
mean of 5,892 lb/acre (Table 9). Yield and bushel weight differences between varieties
______________________________________________________________________________

were both statistically significant. The LKL site was not harvested due to unusually high
weed pressure, as described above. Unlike some of the other trials, yields in 2006 were
higher overall than in 2005. Because this trial was planted in the same field and managed
identically to the other wheat trials at KBREC, we can think of no particular reason for
the relatively better performance of this trial compared to the other spring wheat trials.
All but two entries had bushel weights above the industry standard of 60 lb/bu;
ranging from 57.1 to 63.9 lb/bu, with a mean of 62.3 lb/bu, slightly lower overall than in
2005.
Western Regional Soft Winter Wheat Variety Trial
The Western Regional Soft Winter Wheat trial was planted at the KBREC site
only. Thirty-four entries, including four named varieties and 30 experimental lines, were
planted in the trial. Differences between varieties were statistically significant for both
yield and bushel weight. Yields ranged from 3,190 to 6,570 lb/acre, with a mean of 4,880
lb/acre (Table 10). It is interesting that Stephens, a variety released by OSU decades ago,
had the highest yield. Chukar had a very high yield for a club wheat.
Bushel weights were low in 2006 compared to the OSU Elite Winter Wheat Trial
in 2005, but were similar to the 2006 OSU Elite Winter Wheat Trial results. They ranged
from 55.5 to 59.6 lb/bu, with a mean of only 57.3 lb/bu. The relatively low yields and
bushels weights were attributed to a relatively poor soil in the area where this trial was
planted, as well as possibly less than optimum irrigation management.
Western Regional Hard Winter Wheat Variety Trial
The Western Regional Hard Winter Wheat trial was planted at the KBREC site
only. This was a small trial, as only three named varieties were included. Yields ranged
from 4,070 to 5,050 lb/acre, with a mean of 4,673 lb/acre (Table 11). Bushel weights
were all above 60 lb/bu. They ranged from 61.1 to 63.4 lb/bu with a mean of 62.1 lb/bu.
Not surprisingly for such a small trial, the differences between varieties were not
statistically significant for either yield or bushel weight. Mean yield was similar to the
Western Regional Soft Winter Wheat Trial, but bushel weight mean was much higher in
the Western Regional Hard Winter Wheat Trial.
OSU Elite Winter Wheat Variety Trial
Due to growers’ increased interest in winter wheat information, for the first time
in many years KBREC began testing entries from Jim Peterson’s OSU winter wheat
breeding program during the 2004-2005 growing season, as noted above. We repeated
this trial in 2005-06 using Dr. Peterson’s updated entry list.
In the 2006 trial at the KBREC site, there were 40 entries, including 13 named
varieties and 27 experimental lines. Of these, 5 entries were club varieties and 35 were
soft white varieties. Yield and bushel weight differences between varieties were both
statistically significant. Yields ranged from 2,574 to 4,836 lb/acre, with a mean of 3,894
lb/acre (Table 12). Top entries included OR202787, OR9901619, ORSS-1757,
ORH010085, and ID99-419. Yields overall were much lower than the previous year; in
2005 the mean yield was 5,900 lb/acre. As mentioned above, the winter wheat trials were
______________________________________________________________________________

put in an area of restively poor soil compared to the rest of the station, and irrigation may
have been less than optimal.
All bushel weights were below the industry standard of 60 lb/bu. They ranged
from 54.9 to 59.5 lb/bu, with a mean of 56.9 lb/bu. Bushel weights overall were much
lower than the previous year; in 2005 the mean bushel weight for this trial was 62.7. The
2006 bushel weights in this trial were similar to those in the Western Regional Soft
Winter Wheat Trial, suggesting the growing conditions were uniformly worse for winter
wheat in 2006 compared to 2005, for possible reasons described above.
Using data from the 2004-05 and 2005-06 OSU Elite winter wheat trials, as well
as the 2005-06 Western Regional trials, we can compare multiple-year yield means for 26
named and experimental winter wheat varieties (Table 13). As expected based on results
described above, yields in 2005 were better overall than in 2006, but not for all entries.
Five entries (including the two named varieties Stephens and Chukar) had higher yields
in 2006 than in 2005. Interestingly, even though Stephens was released by OSU decades
ago, it remained in the top 5 for two-year mean yield.
Summary
Trial results for 2006 exhibited somewhat poorer overall growth and yield than in
2005, for the reasons described above. Clearly the serious weed problem at the LKL site
affected the plots there to the point where wheat plots were not harvested and barley plots
were impacted, though harvestable. At the KBREC site, generally poorer growing
conditions due to soil type and irrigation for the winter trials undoubtedly contributed to
the lower than average yields. The spring trials were closer to long term averages for
check varieties, although clearly 2004 and 2005 were better years for small grain
production than 2006. Nonetheless, a few entries did better in 2006 than in 2005,
illustrating how some varieties do very well under better growing conditions, whereas
other varieties with lower absolute potential are able to produce reasonably good yields
under poorer conditions.
