【摘要】 本文论述了选育家蚕高茧层率品种在家蚕育种工作中的重要性及家蚕茧层率遗传的规律。在选育家蚕高茧层品种的实践中,灵活运用个体选择和同蛾区交配的技术和方法,达到提高茧层率的效果。在提高茧层率的运作中,由于蚕体内营养物质分配矛盾,导致体质削弱、产卵量下降的负面效应,创新运用"天平摆动模式"方法,平衡协调被育品种的茧层率与体质、产卵量之间的关系。更多还原

【Abstract】 The importance of breeding silkworm(Bombyx mori) variety with high cocoon shell rate in silkworm breeding field were discussed,as well as the genetic laws of cocoon shell rate.In the practical activity of breeding silkworm variety with high cocoon shell rate,we tried to improve cocoon shell effect by using the technology and method of individual selection and copulation in ’the same area of moths’.In spawning season,due to the contradiction of nutriment distribution,the female silkworm became week with low egg production.The method named balance-swing model was used originally to adjust the balance relationship between constitution and egg production.更多还原
