摘要
用颜色遗传稳定、经济性状较差的黄茧家蚕品种与经济性状较好的现行白茧家蚕品种杂交,培育成经济性状优良、颜色稳定、茧层颜色分布改善的一代杂交种。其全茧量平均比原种提高71.32％,茧层率提高29.71％,平均纤度为3.23D,其他指标均符合生丝原料茧要求。
F1 hybrid with improved economical character and cocoon color has been bred by crossing colored cocoon silkworm to white cocoon silkworm which is different in economical char-acter from colored cocoon silkworm. The average fibre size of F1 hybrid is 3. 23 D and its whole cocoon weight and the percentage of cocoon shell weight increases by 71. 32 % and 29. 71 % re-spectively over that of the F0. The other characters meet the demand of raue cocoon silk.
