Item Evaluation of wheat stem sawfly‐resistant solid stem Qss.msub‐3BL alleles in hard red winter wheat(Wiley, 2023-01) Wong, Mei Ling; Bruckner, Philip L.; Berg, Jim E.; Lamb, Peggy F.; Hofland, Megan L.; Caron, Christopher G.; Heo, Hwa‐Young; Blake, Nancy K.; Weaver, David K.; Cook, Jason P.Host plant resistance provided by solid stems has been the most effective means for mitigating wheat stem sawfly (WSS) (Cephus cinctus Norton) damage in spring and winter wheat (Triticum aestivum L.). The solid stem trait originates from the spring wheat cultivar “Rescue” and is associated with a quantitative trait locus allele Qss.msub-3BL.b that explains the majority of the variation for stem solidness. Recently, a new Qss.msub-3BL solid stem allele, designated Qss.msub-3BL.c, was identified in the spring wheat cultivar “Conan”. It produces a solid stem phenotype early in plant development but dissipates during plant growth. The Qss.msub-3BL.c allele provides effective WSS resistance in spring wheat but has not been tested in winter wheat. To examine if the Qss.msub-3BL.c allele provides adequate WSS resistance in winter wheat, near-isogenic lines (NILs) were developed using marker-assisted backcrossing. This enabled comparisons between the hollow stem Qss.msub-3BL.a, solid stem Qss.msub-3BL.b and solid stem Qss.msub-3BL.c alleles for stem solidness, WSS resistance, and agronomic traits in Montana growing environments. Compared to the hollow stem allele, the NILs with the Qss.msub-3BL.c allele increased stem solidness and reduced WSS stem cutting. However, the Qss.msub-3BL.c allele resulted in lower solid stem scores and greater WSS stem cutting compared to the Qss.msub-3BL.b allele. Overall, these findings indicate that the Qss.msub-3BL.c allele failed to provide sufficient WSS resistance in the winter wheat backgrounds tested in this study.Item Registration of ‘Bobcat’ hard red winter wheat(Wiley, 2020-06) Bruckner, Phil L.; Berg, Jim E.; Lamb, Peggy F.; Kephart, Ken D.; Eberly, J.

No. CV-1114, PI 676026) hard red winter wheat (Triticum aestivum L.) was developed and released by the Montana Agricultural Experiment Station in 2015. Northern was derived from a composite of two crosses, MT9982//MTW0072/NW97151 and MTW0047//MTW0072/NW97151. Northern was developed using a modified bulk breeding method and selected as an F-5:7 headrow. Northern was tested under the experimental number MT0978 in Montana yield trials from 2009 to 2015. Like predominant cultivar Yellowstone, Northern is a high-yielding, winter-hardy hard red winter wheat cultivar with medium to late maturity, medium to high grain protein, and acceptable milling and baking quality. Northern was released for its excellent performance in winter wheat production environments of north-central Montana, reduced plant height, and improved grain volume weight and resistance to stem rust (caused by Puccinia graminis Pers.: Pers. f. sp. tritici Eriks. & E.

The 2000 no-till recrop oat trial was seeded into barley stubble. Soil moisture was fair to good for seeding in the spring. The surface soil was almost mud due to the shade and shelter provided by the standing stubble and chaff. The no-till recrop yields were slightly reduced due to the low precipitation levels during the 2000 crop year. The combination of good vegetation control and the water conservation provided with no-till provided for good yields in a dry year.Item Winter Wheat Variety Evaluation in Off-Station and Re-Crop Trials Near Moccasin, Denton, Fort Benton, Moore, and Winifred (2000)(Central Agricultural Research Center, 2000) Berg, Jim E.; Bruckner, Phil L.; Philips, Dave; Sharp, Gail L.; Vavrovsky, Joe; Wargo, Judee; Wichman, David M.This report evaluates the performance of winter wheat varieties in environments and cropping methods. Dry conditions resulted in lower than average yields at all sites with the exception of Moccasin where re-crop wheat followed barley. Growing season precipitation of 3.9 inches at the Fort Benton site contributed to low yields ranging from 8.8 to 12.6 bu/a. Yields were highest at the Moccasin site ranging from 35.8 to 46.2 bu/a. No yields were recorded at the Denton site due to a plugged opener during seeding that resulted in non-uniform plots. Grain protein was lowest at the Denton site and highest at the Fort Benton site. Although moisture for the 2000 crop season was generally higher than that received the previous year, timing of rainfall contributed to a lower than average yield at most sites. Yields at the Moccasin site met the seven-year average for cultivars grown at that site. Yields at all other sites were well below their ten-year averages as noted in multi-year yield summaries for each site. seeded into spring wheat stubble. The Moccasin trial was seeded into barley stubble. All cultivars had acceptable test weights averaging 61.2 lbs/bu across all sites and all cultivars. TestItem Evaluation of Experimental Winter Triticale Lines for Adaptation in Montana (2001)(Central Agricultural Research Center, 2001) Berg, Jim E.; Hensleigh, Pat F.; Hybner, Roger M.; Kephart, Ken D.; Kolding, Matt; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.This report documents the observations of winter triticale lines to determine if any perform well in Central Montana. Triticale plots were seeded on a west-facing slope to obtain maximum exposure to winter temperatures and wind. Plant densities and percent stand indicate no significant differences among the triticale lines in their ability to survive winter. Triticale lines did not differ significantly from Tiber winter wheat in winter hardiness or in grain yield. Grain yields averaged 2520 lbs/a and test weights were above average at 53.6 lbs/bu. Similar results were obtained in the Statewide Triticale Nursery planted in a more protected area on the research center. Triticale lines tested had a wide range of heading dates and test weight values. Early maturing lines with acceptable test weights and yields comparable to Tiber winter wheat can be selected for and continued in subsequent yield trials.Item Statewide Winter Triticale Trial (2001)(Central Agricultural Research Center, 2001) Berg, Jim E.; Hensleigh, Pat F.; Hybner, Roger M.; Kephart, Ken D.; Kolding, Matt; Sharp, Gail L.; Vavrovsky, Joe; Wichman, David M.This report evaluates winter triticale selections which exhibit high yield, good quality, and winter hardiness in environments and cropping methods representative of Montana. To develop a winter feed grain adapted to livestock production areas in eastern Montana because seeding spring grains conflicts with calving and lambing. Differences in yield between cultivars were not significant at the Bozeman or Huntley sites and no single cultivar was the highest yielding at all sites. Test weights for the triticale entries ranged from 48.7 to 57.3 lbs/bu based on a standard of 50 lbs/bu. The average test weight for all entries and all locations was 54.7 lbs/bu, well below that of Tiber winter wheat but above the standard of 50 lbs/bu. Grain protein levels ranged from 14.0 to 19.1 percent and nursery averages were generally one percent lower than that of Tiber winter wheat.
