【摘要】 雄蚕生命力较雌蚕强,食桑少,叶丝转化率和茧层率高,雄蚕丝的纤度细,丝质优,容易缫制高品位的生丝。专养雄蚕是蚕业未来发展的主要方向,利用性连锁平衡致死基因控制蚕的性别以实现专养雄蚕是一项高新技术,已达到实用化水平。本文在总结实际操作经验的基础上,对利用性连锁平衡致死系进行雄蚕品种选育的方法进行了简要的阐述,有助于科研工作者在该领域内积极地进行探索和交流。更多还原

【Abstract】 Compared with female silkworm,male silkworm is stronger,less food,higher the leaf-silk conversion rate and cocoon shell rate.The silk of male silkworm,with small size and excellent characters,is to be easy to reel high-grade raw silk.Rearing male silkworm only is the main direction of sericulture development in the future,The high-tech,using sex-controlled lethal genes balanced on silkworm sex chromosome to achieved only rearing male silkworm,has reached a practical level.Based on the practical experience,methods of the breeding of male silkworm Varietis by sex-linked lethal balancing lines have been expatiated,and it will be benefit to investigators actively exploring and exchanging in the field.更多还原
