| 摘 要： | 对家蚕和野桑蚕远缘杂交后代茧丝遗传分析表明:两亲本茧丝性状差异远远大于家蚕品种间差异;全茧量、茧层率、丝长、纤度杂种F_1代偏向野桑蚕,没有杂种优势存在;回交一代接近家蚕,F_2代呈中间类型,各性状的趋势表现为野桑蚕

| Abstract: | Progenies of outbreeding between domestic silkworm and wild silkorm were observed. Theresults showed that cocoon weight, cocoon shell weight, cocoon shell ratio, filament length andsize of F_1 were similar to those of their wild parent, the characters of BC_1 took after those of thedomestic silkworm parent, and those of F_2 were between those of parents, the general trend waswild silkworm
