Abstract: Under potting drought stress condition , drought resistance of eleven accessions of eight Chinese wild Vitis species and 107 F₁ hybrids of V. yeshanesis ×V. riparia was identified based on the evaluation methods
of degree of etiolating (DE) , relative water content (RWC) , and plasma membrane permeability ( PMP) in the leaves. The results showed that the accession of ‘Yanshan21’of V. yeshanesis was the highest resistant to the
drought stress ; the accession of ‘Taishan21’of V. adsricta had middle resistance ; the accessions of ‘Anlin22’of V. adstricta , ‘Taishan211’of V. amurensis , ‘Jiangxi22’and ‘Pingli27’of V. romanetii , ‘Gansu291’
and‘Nanzheng22’of V. piasezkii ,‘Weinan23’of V. quinquangularis , and‘Guangxi21’of V. pseudoreticule lata had lower resistance ; ‘Tangwei’of V. davidii is susceptible to the drought stress. There are demonstrated continuous genetic segregation of drought resistance in F₁ progenies of V. yeshanesis ×V. riparia. Specifically , a few hybrids showed higher heredity than resistant parents in the tolerance to drought stress.
