QTL Analysis of Fiber Yield and Quality and Resistance to Verticillium Wilt Using Gossypium hirsutum and G.barbadense Advanced Backcross Populations

摘要

To introgress elite QTL alleles of Gossypium barbadense L.for fiber yield and quality and resistance to Verticillium wilt into G.hirsutum L.,enlarge the genetic base of G.hirsutum,and provide new germplasm resources for the variety development,the cultivars Zhongmiansuo 36,G.hirsutum,and Hai 1,G.barbadense,were used as recurrent and donor parent,respectively,to produce BC1 F1,BC1S1,and BC2F1 populations.QTL analyses of fiber quality,yield-related,Key words: interspecific backcrosss; AB-QTL; fiber quality; yield; Verticillium wilt resistance
