摘　　要：采用杂交、兄妹交和自交等育种方法，育成无蜡粉的显性核不育纯合两型系。利用该两型系进行全不育系制种，无蜡粉可作为苗期育性的指示性状，能有效地区别因纯合两型系内可育株迟拔或漏拔而产生的杂株，从而提高全不育系和杂交种的纯度。The w axless hom ozygous tw o type line of dom inant genic m ale sterility in Brassica napus L.has been bred by cross,sib m ating and selfing.The w axless character as a genetic m arker can be easily used to distinguish fertile plants from sterile plants in full sterile line during the seedling period.So it can be easier to produce purer full sterile line and hybrid seeds.
