摘  要:
The sex limited male silkworm isogenic line Xia sch and Qiu sch which could be used in commerce was obtained through the introduction of sex linked chocolate gene into a variety with good economic characters.The combined hybrids Xiafang×Qiu sch and Qiubai×Xia sch are male silkworm variety which showed excellent scores when reared both in laboratory and countryside on a small scale.The newly bred variety can be used in practice,which reduces the production cost of male silkworm variety.
