【Abstract】 This paper briefly described the achievements on herediary laws of fluorine-resistance,the relationships between combining ability of varieties and characters of development and fluorine-resistance,improving the ability of varieties to fluorine-resistance with silkworm pedigree breeding and improved way by cross breeding,and also selecting and breeding a number of new varieties of resistance to fluorine recently in China.Improved way by cross breeding was better than the method of pedigree breeding in improving the ability of silkworm varieties to fluorine-resistance.更多还原
