Aceria Tosichella

Incidence of High Plains Disease (HPD) in a susceptible corn cultivar was examined in relation to planting dates, insecticide treatments, and wheat heading dates during 1994 to 1996. In the High Plains of Texas, this disease of susceptible corn was related to corn planting dates and winter wheat maturity. The incidence of HPD varied greatly from year to year; however, corn planted between 16 and 20 May had the highest disease incidence. Corn planted 10 to 30 days after wheat heading had the highest incidence of the disease. Chemical control of the vector, Aceria tosichella, was ineffective, except by the use of granular insecticides applied at planting, which had some beneficial effects. Results of this study suggest that producers can reduce the incidence of HPD by planting corn before or after the peak migration of wheat curl mite from wheat.

AAC Elevate is a hard red winter wheat (Triticum aestivum L.) cultivar that is well adapted across western Canada and eligible for all grades of the Canada Western Red Winter (CWRW) wheat class. It was developed using wheat×maize-pollen doubled haploid methodology. AAC Elevate was evaluated in the Western Winter Wheat Cooperative Registration trials relative to CDC Osprey, AC Bellatrix, Radiant and CDC Buteo for 3 yr (2011–2013), with Flourish and Moats added as checks in the latter 2 yr. Based on these 35 replicated trials, AAC Elevate produced higher grain yield than all of the checks (103.3–114.4%) and exhibited good winter survival, medium height with excellent straw strength, large kernels, acceptable end-use quality, and broad disease resistance. AAC Elevate expressed moderate resistance to stem rust and common bunt, intermediate resistance to leaf rust, stripe rust and Fusarium head blight, and resistance to colonization by the wheat curl mite vector for wheat streak mosaic virus.

Height Predictions

Winter wheat (Triticum aestivum L.) plant height is an important trait for the diverse environmental conditions found in the Great Plains. It has been related to seedling emergence, lodging, soil erosion, ease of harvest, crop residue and weed control. The hypothesis that transpiration, which integrates atmosphere, soil, and plant processes, could be used to characterize environmental effects on wheat plant height was tested in this research. Data from four commercial winter wheat cultivars (Arapahoe, TAM107, Vista, and Siouxland) and nine environments in Nebraska in 1992 and 1993 were used. The climatic regions represented in this study ranged from sub-humid to semiarid. To test our hypothesis, a spring wheat growth and yield model was modified to predict plant height development (modeled as a sigmoidal function of time) in winter wheat. Daily height increment was based on the ratio of actual to potential transpiration. The model was run for these four cultivars in eight environments. Data from the ninth environment was used to estimate maximum plant height for each cultivar; a necessary input into the model. Modeled plant height predictions were in good agreement with actual measurements for all environments (R2 = 0.80). Based on these results, we conclude that transpiration was a good indicator of environment for plant height development in winter wheat.
