【摘要】 在安徽省农科院作物所试验基地发现了芝麻雄性不育株 ,将其与可育株特征进行观察研究 ,结果表明 :二者主要区别是不育株雄蕊败育彻底 ,雌蕊发育正常 ,具有正常的结实能力 ,镜检后花粉败育率为 99.9% ,而可育株雄蕊、雌蕊、结实均正常 ,花粉败育率仅为 2 .0 %。初步的遗传分析表明 ,控制雄性不育的遗传物质在细胞核中 ;在不同的基因型中 ,雄性不育性状受 1～ 2对隐性基因控制 ;在某些基因型中 ,雄性不育性状可能受两个以上基因位点控制。更多还原

【Abstract】 Some sesame male sterile plants were discovered in our experiment base.The observation showed that the male abortion was complete,the female fertility was normal and the ration of the abortion pollen of male sterile plant was 99.9%.The primary hereditary analysis proved that heredity material controlling the male sterility was in cell nucleus.The male sterility was controlled by 1～2 gene alleles in the different genotypes.In some genotypes,the male sterility could be controlled by more than two gene alleles.更多还原
