| 摘 要： | 三眠性家蚕具有茧丝纤度细、可缫制高品位生丝(5~6A级)的优点,细纤度生丝可全部用于出口,是我国家蚕品种研究的主要方向之一。通过对贵州地方三眠家蚕与普通四眠蚕的遗传显隐性表现研究,鉴定了贵州三眠蚕品种"202"对普通四眠蚕品种781、丰1、渝1、782等的遗传强势性。同时从鉴定的杂交组合中选择具有生产性能优的组合进行定向培育,选育出适应贵州条件的三眠蚕品种材料,结果培育了4个性能优良的品种材料,为实用三眠蚕品种的育成完成了前期研究工作。

| Abstract: | The breeding of trimolting silkworm is one of main directions in silkworm breeding because the quality raw silk can be made from cocoons of trimolting silkworms.Guizhou 202,a trimolting silkworm variety has the strong heredity in crosses between Guizhou 202 with trimolting and 781,feng 1,yu 1 and 782 with tetramolting.Four quality silkworm breeding materials with trimolting were selected,which provides the basic for breeding of practical trimolting silkworm in Guizhou. |
