Abstract：Zhong 221 , widely popularized Gossypium hirsutum variety in cotton production , was hybrid-ized with Gossypium barbadense cultivar Hai 1.The progenies were backcrossed with Zhong 221.After succes-sive inbreeding , the chromosome segment substitution lines containing genes from G.barbadense on the genetic background of G.hirsutum were established combined with SSR molecular marker technology .The yield and fiber quality related traits of BC 4 F4 were analyzed by phenotypic principal component analysis method .The re-sults showed that there were contradictions between yield traits and fiber quality characters which were difficult to reconcile .And their genetic correlations could be reflected by the relationship of boll weight and fiber length.
