摘　　要：用６０Ｃｏ—γ射线３００、５００和７００Ｇｙ处理芝麻良种豫芝４号干种子。从大约６万个Ｍ２植株中筛选出１０个雄性不育株。对该１０个雄性不育株Ｍ３、Ｍ４作进一步鉴定，获得了６个不育性状稳定、经济性状较好的雄性不育突变体。初步遗传研究表明，该６个雄性不育突变体为一对隐性基因控制的核型雄性不育突变体。The dry seeds of a high yielding variety Yuzhi No.4 were irradiated by 60Co —γ rays with 300, 500 and 700 Gy. 10 male sterile plants were screened out from 60,000 M 2 plants. Through a further identification of the 10 male sterile plants in M 3 and M 4, 6 male sterile mutants were obtained. Result of a genetic research showed that the 6 male sterile mutants were genic male sterility (GMS).
