Abstract: This study compared six common cultivars or crossbreeding varieties (lines) of resistance to drought, and the results identified could not only be utilized to provide a basis for selection and variety deployment, as parent materials in breeding for drought resistance. It studied the differences of the drought resistant ability by taking plant growth, drought, leaf water potential, electrical conductivity and the condition of root under water stress. The results suggested that‘Flame Seedless’and‘Centennial Seedless’had severely inhibited growth, the drought were serious, the conductivity were changed greatly, the root growth were bad, individual had been dried;‘Wen Suhong’,‘Xinyu’and‘Thompson Seedless’showed relatively ideal;‘SP522’low under severe water stress. Consequently,‘Wen Suhong’,‘Xinyu’and‘Thompson Seedless’were strong,‘SP522’ranked low, and‘Centennial Seedless’and‘Flame Seedless’ranked lower.
