摘要
试验用新九与伴1等4个温敏性的品种杂交，将其F1代蚕种用高温干燥条件催青，结果雄蚕正常孵化，雌蚕几乎不孵化，表明伴1等品种具有控制催青温敏性表达的基因存在。用华1与伴1组配的F1、F2及F1与亲本回交的14个组合作遗传分析，认为催青敏感性状由位于Z性染色体上的一个主基因控制，呈隐性的伴性遗传。
The experiments were conducted by crossing xin-9 with ban-1 and three other temperature-sensitive varieties, then incubating their F1 eggs under high temperature andlow humidity conditions. The results showed that the male eggs hatched normally,whilethe female eggs scarely hatched. It suggested that genes controlling temperature--sensitivity expression existed in these four varieties,namely,Ban-1,Ban-2,K05, S-ban. Genetic analysis was done on 14 hybridized forms of Hua-1 with Ban-1, including F1,F2 and F1backcrossing with their parents. It is considered that the temperature sensitive characteris controlled by a major gene, located in Z chromosome, which shows recessive sexlinked inheritance.
