油菜化学杀雄技术在西藏的应用与思考
Application and Thinking of Chemical Induced Male Sterility Technology on Brassica napus in Xizang
摘要
Abstract
The heterosis utilization was one of the most effective ways to increase the crop yield.At present,the approaches to utilizing hetero-sis on Brassica napus mainly include the nuclear male sterility(GMS),the cytoplasmic male sterility(CMS),the self incompatibility(SI),and the chemical induced male sterility(CHA).Among these,the chemical induced male sterility was the most economically effective method for rapidly developing new hybrid varieties,due to its lack of cytoplasmic adverse effects,freedom in combination selection,complete sterility,rela-tively simple breeding procedures,and short breeding cycles.Based on the uniqueness of rapeseed cultivation in Xizang,this paper introduces the principle of chemical male sterility of rapeseed,commonly used agents,and the current research situation of chemical male sterility of rape-seed in Xizang.It also analyzes the problems and challenges faced by chemical male sterility of rapeseed in Xizang.关键词
