摘　　要：分析了家蚕15个经济性状在不同年份和季节饲养的5次试验的杂种优势表现。得出:在不同的环境条件下,家蚕经济性状的杂种优势率的均值和均方均存在着明显的差异,因而可以把家蚕的经济性状根据其杂种优势的表现不同分成几类,文章讨论了各类性状对组配杂交组合的影响。Analysis of heterosis phenomena of 15 economic traits of silkworm Bombyx mori in different years and seasons showed that mean heterosis and mean variance of economic traits of silkworm were varied signifivcantly in different environmental conditions. Therefore, the economic traits of silkworm can be divided into several categories based on the performance of heterosis. Effect of each type of heterosis on pairing of hybrids was also discussed in the present paper.
