Resistance of high quality wheat variety ‘Xiaoyan 54’to environmental stress and diseases in south of Henan Province

‘Xiaoyan 54’was introduced into the south of Henan Province in 1997，and now is grown widely in this area．Investigation on four-year cultivation indicates that‘Xiaoyan 54’has high resistance to freezing，drought，waterlogging stress，and diseases and has high grain yield．We have studied the root morphology，characters of functional leaves and nutrient using efficiencies of‘Xiaoyan 54’．The results suggest that the high resistance of‘Xiaoyan 54’to environmental stresses relates with its powerful root system ，erect flag leaf，and the resistance to lodge．
