OBJECTIVES: To provide wheat growers in south central Montana with a reliable, unbiased and
up-to-date source of information that will permit valid comparisons among
improved winter wheat varieties. This information should help winter wheat
producers in south central Montana select varieties best suited to their particular
area and growing conditions.
METHODS: The 2018 off-station winter wheat trials were established under irrigation at Huntley
and under dryland conditions near Molt; Fort Smith, Hardin, Hysham, and Rapelje
under no-till, chemical fallow conditions (Fig. 1). Each trial contained 25 winter
wheat cultivars (14 commercial, 11 experimental), and was planted using a
partially-balanced lattice design under dryland and irrigated conditions with three
replications. All entries were seeded at approximately 1 million seeds per acre
under dryland conditions (~60 lb/a) and 1.5 million seeds per acre under irrigation
(~90 lb/a). Dryland test plots consisted of a 16-foot, 4-row plot with 15-inch row
spacing. Irrigated test plots consisted of a 16-foot, 7-row plot with 7-inch row
spacing. All rows of each harvested test plot were trimmed 36 inches and
harvested using a plot combine.
Recorded grain yields were adjusted to 13% grain moisture content, and are
reported in bushels per acre based on a 60 pound standard bushel weight. Two
year (2017-18) and three year (2016-18) yield averages are provided for cultivars
tested during previous years. Test weight (pounds per bushel) and grain

moisture content (percent) were obtained for each plot using a Dickey-john GAC
2100 grain analyzer. Grain protein content (percent) was determined by near-
infrared reflectance for each harvested sample, and adjusted to 12% grain
moisture content. Plant height was measured in inches from the soil surface to
the top of the head, excluding the awns if present. Corresponding calendar dates
also are presented. Information pertaining to the specific cultural management of
each study site is listed at the bottom of their respective data table (Tables 1
through 8).
RESULTS: The 2018 winter wheat test sites had above average rain or snow accumulation
during winter months except in October. Precipitation during the months of
September and November provided adequate soil moisture for winter wheat
planting and emergence. Above-average precipitation from March through June
resulted in good stand establishment and higher grain yield. However, above
average rainfall in August and below average temperature throughout the 2018
growing season, except in May, delayed wheat maturity. Moreover, winter wheat
crop was lost due to a severe hailstorm at Hysham
Irrigated winter wheat trial was established at Huntley in 2018. Winter wheat stand
was excellent but lodging resulted in reduced yield for some entries at this location.
Grain yield averaged 100 bu/ac and ranged from 76 bu/a for experimental line
‘MTF1435’ to 135 bu/a for cultivar ‘LCS Jet’ (Table 1). Cultivar ‘Keldin’ produced
yield that was statistically equal to the yield of highest yielding cultivar. Test weight
values under irrigated conditions, averaged only 59.2 lb/bu. Test weight ranged
from 56.3 lb/bu for ‘WB4483’ to 61.8 lb/bu for Keldin. Grain protein content was
excellent and all entries have protein content above 13 percent. Protein content
averaged 13.9 percent. Two- (2017-18) and three-year (2016-2018) average yield
for winter wheat varieties tested at Huntley was 103 and 104 bu/a respectively.
‘Keldin’ was the highest yielding cultivar averaged over the last two- and three
years.
Average yield under dryland conditions at Rapelje in 2018 was excellent, average
119 bu/a (Table 2), twice the winter wheat yield observed at this site in 2016 and
2017. Rapelje was the highest winter wheat yielding site in 2018. Grain yield
ranged from 96 bu/a for forage entry MTF1435 to 139 bu/a for ‘SY Monument’.
Three other entries produced yield that was statistically equal to the yield of highest
yielding cultivar. Test weight was good and averaged 61.5 lb/bu. All entries except
LCS Jet, ‘MT1642’, and ‘Ray’ produced test weight over 60 bu/ac at this site. Grain
protein was good and averaged 13.4 percent and ranged from 12.5 percent to 14.6
percent. Two-year average yield for winter wheat varieties tested at Rapelje during
2017 and 2018 was 89 bu/a. Three-year average yield 2016 through 2018 was 78
bu/a.
Winter wheat yield under dryland condition at Hardin during 2018 was significantly
higher compared to previous years and averaged 100 bu/a (Table 3). Higher than
normal precipitation and cooler temperature contributed to higher yield at this
location. Yield ranged from 73 bu/a for ‘MTF1435’ to 114 bu/a for Keldin. Test
weight averaged 60.9 lb/bu. Test weight ranged from 55.6 to 64.5 lb/bu. Grain
protein content averaged 12.5 percent. Protein content ranged from 11.8 percent
for ‘MTW1491’ to 13.8 percent for MTF1435. Two-year average yield for winter
wheat varieties tested during 2017 and 2018 was 69 bu/a. Three-year average
yield for winter wheat varieties tested from 2016 to 2018 was 62 bu/a.
Average yield under dryland conditions at Molt was 56 bu/a (Table 4) about 3 bu/ac
lower than last year. Chickpea was planted at this location in 2017 and chickpea
seed left in the field in the fall, emerged in late spring (April-May) in 2018. This
negatively affected the winter wheat stand and increased competition with
volunteer chickpea resulted in reduced yield at this location. Yield ranged from 41
bu/a for MTF1435 to 73 bu/a for LCS Jet. Cultivars ‘Decade’ and ‘Northern’
produced yield that was statistically equal to the yield of LCS Jet. Test weight
averaged 61.1 lb/bu and ranged from 58.9 to 63.5 lb/bu. Grain protein content
averaged 11.2 percent. Two-year average yield for winter wheat varieties tested
at Molt during 2017 and 2018 was 58 bu/a, while three-year average yield during
2016 to 2018 was 57 bu/a.
Average yield under dryland conditions at Fort Smith was 83 bu/a (Table 5). Yield
ranged from 56 bu/a for ‘Brawl CLP’ to 97 bu/a for Keldin. Eleven other entries
produced yield that was statistically equal to the yield of highest yielding cultivar.
Test weight was relatively low and averaged 59.1 lb/bu. Test weight ranged from
56.4 lb/bu to 61.6 bu/a. Grain protein content averaged 13.2 percent and ranged
from 12.2 percent to 15.4 percent. Two-year average yield for winter wheat
varieties tested at Fort Smith in 2016 and 2018 was 68 bu/a, with Keldin being the
highest yielding cultivar producing 80 bu/a grain yield.
SUMMARY: In 2018 adequate soil moisture at planting time resulted in good winter wheat
stand. Above-average precipitation during the 2018 wheat growing season
resulted in higher grain yield at all dryland locations except Molt, MT. Grain
production at dryland test sites ranged from 55 bu/a at Molt to 119 bu/a at Rapelje
(Table 6). LCS Jet was the highest yielding cultivar under dryland conditions,
producing 100 bu/a (Table 8) and averaged the highest yield of 107 bu/a across
all test locations in 2018 (Table 7). Keldin and Northern were also top yielding
cultivars, followed by SY Monument. Since 2016, in experiments representing 14
location-years in southcentral Montana, Keldin was the highest yielding cultivar
producing 77 and 67 bu/a over the past two- and three-years respectively across
all dryland locations (Table 8).
