White Wheat Grain Quality Changes with Genotype, Nitrogen Fertilization, and Water Stress

The production of hard white winter (HWW) wheats (Triticum aestivum L.) with acceptable protein content and quality over different environments requires the correct combination of genotypes and management practices. The objectives of this study were to evaluate moisture deficit and N management on g...

Zusammenfassung:	The production of hard white winter (HWW) wheats (Triticum aestivum L.) with acceptable protein content and quality over different environments requires the correct combination of genotypes and management practices. The objectives of this study were to evaluate moisture deficit and N management on grain protein and quality of seven HWW and two soft white winter (SWW) genotypes, and to identify genotypes and traits that minimize grain quality variability. Plots were irrigated during grain fill to replace from 100 to
