Abstract:
... BACKGROUND: Evolution and spread of resistance to glyphosate in kochia [Bassia scoparia (L.) A.J. Scott] is a major challenge for the sustainability of glyphosate‐resistant crop technology in this region. Dicamba offers a viable option to manage glyphosate‐resistant kochia. However, the recent and rapid evolution of dicamba resistance in glyphosate‐resistant kochia populations in Kansas (KS), and ...

Abstract:
... Foliar fungicides can account for a large portion of the yield gap in winter wheat (Triticum aestivum L.); however, their impacts on yield have been inconsistent in rainfed environments. We compiled a database of replicated field experiments and producer-reported fungicide and yield data from commercial fields to quantify the effects of fungicide application on winter wheat yield and yield stabili ...

Abstract:
... Kochia [Bassia scoparia (L.) A. J. Scott] is one of the most troublesome weeds throughout the North American Great Plains. Herbicides such as glyphosate and dicamba have been used widely to control B. scoparia for decades. However, many B. scoparia populations have evolved resistance to these herbicides due to selection. Especially, dicamba-resistant B. scoparia populations are often also found to ...

Abstract:
... Resistance to wheat spike blast (WSB), caused by the Magnaporthe oryzae triticum pathotype (MoT), has relied upon a single major source: the 2NᵛS translocation introgressed from the wild relative Aegilops ventricosa Tausch. However, this resistance is partial and recently partially overcome by newer MoT races. To characterize potential novel loci conferring resistance to WSB, we conducted a genome ...

Heat stress is one of the major environmental constraints for wheat production worldwide. Temperatures above 25°C during the grain filling stage significantly reduced wheat yield and quality. This reduction was reported due to the inactivation of the soluble starch syntha ...

Abstract:
... Wheat (Triticum aestivum L.) grain contains phenolic compounds that act as antioxidants when the bran is included in the human diet. Plants produce phenolics as a defense response to, among other factors, insect and fungal attack, presumably acting through systemic acquired resistance (SAR). This study investigated this hypothesis using synthetic elicitors of SAR. Elicitor solutions known to expre ...

Abstract:
... Wheat (Triticum aestivum L.) cultivars must possess suitable end‐use quality for release and consumer acceptability. However, breeding for quality traits is often considered a secondary target relative to yield largely because of amount of seed needed and expense. Without testing and selection, many undesirable materials are advanced, expending additional resources. Here, we develop and validate w ...

Abstract:
... Pre-harvest sprouting (PHS) in wheat can cause substantial reduction in grain yield and end-use quality. Grain color (GC) together with other components affect PHS resistance. Several quantitative trait loci (QTLs) have been reported for PHS resistance, among which one gene responsible for PHS resistance on chromosome 3AS (TaPHS1) has been cloned. To determine genetic architecture of both traits a ...
