Evaluation of Drought Resistance of Winter Wheat Varieties Based on Principal Component Analysis

[Objective]The long growth cycle and wide seasonal span of wheat make it vulnerable to frequent drought stress,which poses a serious threat to wheat production.Selecting drought-resistant varieties is an effective way to improve wheat production.[Method]In this study,275 wheat varieties from different sources were planted separately under normal winter irrigation(well-water,WW)in Yangling,water limited after flowering(WL),and rain-fed conditions in Heyang Ga…查看全部>>
