现已证明,能使数量性状改变的微突变对于改良家蚕的经济性状是有用的。诱导家蚕的有利突变在二化性品种上已有成功的试验,还需对印度卡纳塔克地区大量饲养的多化性迈索尔纯种的经济性状进行改良。因此,用迈索尔纯种进行了突变育种试验。材料与方法不同品系的多化性家蚕迈索尔纯种饲养在标准实验室条件下,调查其经济性状,选得其 It has been demonstrated that micro-mutations that allow quantitative trait changes are useful for improving the economic traits of silkworms. Successful mutagenesis to induce silkworms has been successfully tested on two sex varieties and the economic traits of the pleomorphic Mysore, which is largely reared in Karnataka, India, need to be improved. Therefore, a mutation breeding test was conducted with Mysore purebred. Materials and Methods Variety of different strains of silkworm Mysore purebred reared under standard laboratory conditions, to investigate the economic traits, choose its
