随着棉花育种工作的发展,为了改变棉花种性,选出具有突破性状的新品种。必须通过种间杂交,引入新的种质。因此,棉花的育种方法,也由系统育种、品种间杂交,转向以种间杂交为主的综合育种。所以棉花的远缘杂交受到国内、外研究者的普遍重视,并已取得成效。从1927年Zaiger首次报道得到非洲棉(G.herbaceum)和陆地棉(G.hirsutum)种间杂交种以来,棉花育种工作者应用种间杂交方法,培育出一些新品种(类型)。如我国用 With the development of cotton breeding, in order to change the cotton variety, select the new varieties with breakthrough traits. New germplasm must be introduced through interspecific crossing. Therefore, cotton breeding methods, but also by the system of breeding, hybrids between varieties, turned to interspecific hybrids based breeding. Therefore, distant hybridization of cotton has been widely valued by domestic and foreign researchers and has achieved some success. Since Zaiger first reported the crossbreeding of G.herbaceum and G. hirsutum in 1927, cotton breeders have developed some new varieties (types) by means of interspecific hybridization. If my use
