He-Ne激光辐照野桑蚕子代变异体继代遗传的研究
Research of Successive Inherit of Filial Variant of Bombyx mandarina Radiated With He -Ne Laser
【摘要】 He -Ne激光辐照野桑蚕蛹的子代 ,获得长茧丝 (SC)和斑纹变异 (BW)个体 ,经继代饲养 ,对其发育、形态性状、茧质和丝质进行调查、统计和F测验 ,SC区的丝长和纤度与对照区差异达到显著和极显著程度 ,而BW区表现为变异谱扩大 ,产生变异油蚕。因此He -Ne激光对野桑蚕具有遗传诱变效应 ,诱变出长茧丝、细纤度特殊经济性状的个体 ,在育种上有实用意义
