Genetic variation and the effectiveness of early-generation selection for soft winter wheat quality and gluten strength
Selection for milling and baking quality in wheat (Triticum aestivum L.) head-rows could increase the efficiency of most soft winter wheat (SWW) breeding programs. We evaluated whole grain-wheat meal (WM) assays for their ability to select lines with acceptable SWW quality and high gluten strength in early-generations and estimated heritability of SWW quality and gluten strength. One hundred ...

Land application of sugar beet by-products: effects on Nitrogen mineralization and crop yields
Land application of food processing wastes has become an acceptable practice because of the nutrient value of the wastes and potential cost savings in their disposal. Spoiled beets and pulp are among the main by-products generated by the sugar beet (Beta vulgaris L.) processing industry. Farmers commonly land apply these by-products at rates >224 Mg ha–1 on a fresh weight basis. However, ...

Cattle gain and crop yield for a dryland wheat-sorghum-fallow rotation
Increasing pumping costs and declining well capacities in the U.S. Southern High Plains have led to greater reliance on less productive and inherently riskier dryland cropping systems. Dryland wheat (Triticum aestivum L.) and grain sorghum [Sorghum bicolor (L.) Moench] are typically grown in a 3-yr wheat-sorghum-fallow (WSF) rotation that may be intensified by integrating cattle (Bos taurus) ...

Hierarchical modelling applied to agriculture: wheat planting decisions in the Pacific Northwest
This paper presents a hierarchical decision model that predicted Alturas soft white spring wheat would be the best spring wheat variety to plant in the Pacific Northwest in 2006. Profitability depends on changing market demands and competition with other crops. The challenge of wheat farming is sustaining profitability. A four level hierarchical decision model approach was selected for this ...

Effect of dwarfing Rht genes on Fusarium head blight resistance in two sets of near-isogenic lines of wheat and check cultivars
Reduced height (Rht) genes are used in wheat (Triticum aestivum L.) breeding throughout the world. Fusarium head blight (FHB) is one of the most destructive wheat diseases caused by Fusarium graminearum (Schwabe) and F. culmorum (W.G. Sm.) Sacc. Objectives of this study were to analyze the effects of (i) specific Rht dwarfing genes on FHB reaction using two sets of near-isogenic lines (NILs) and ...

Genetic analysis of slow-rusting resistance to leaf rust in durum wheat
Leaf rust (caused by Puccinia triticina Eriks.) is a widespread disease of wheat (Triticum spp.) that can be controlled effectively through the use of genetic resistance. Little is known about the slow-rusting type of resistance to leaf rust in durum wheat [Triticum turgidum L. ssp. durum (Desf.) Husn.]. The genetic basis of slow-rusting resistance was investigated in eight International Maize ...

Chilling tolerance of Wheat seedlings is related to an enhanced alternative respiratory pathway
Pretreatment with exogenous hydrogen peroxide (H2O2) mitigated the water loss of wheat leaves exposed to 4°C for 24 h. The same treatment also partially reduced the increases of electrolyte leakage and H2O2 production of the chilled plants. These observations suggest that H2O2 pretreatment could effectively induce chilling tolerance. The capacity of the alternative respiratory pathway and the ...
