1978年春在武汉地区“慈惠白”萝卜留种群体中发现了雄性不育株,其出现频率为0.025%。通过定向选育,育成了392A雄性不育系,该雄性不育系雄性器官退化,花药干瘪、不开裂,小孢子畸变,完全不育;但雌性器官发育正常,授粉后结实良好。研究结果还表明,392A雄性不育系为胞核质型不育系,具有与41-5A雄性不育系不同的细胞质类型。 In the spring of 1978, a male-sterile strain was found in the remaining populations of radish in the “Cihui white” region of Wuhan. Its frequency of occurrence was 0.025%. Through directional breeding, 392A male sterile line was bred. Male sterile lines of male sterile lines degenerated, anthers shriveled, did not crack, microspore aberrations and completely sterilized. However, the female organs developed normally with good fruiting after pollination. The results also show that the 392A male sterile line is a cytoplasmic male sterile line with a different cytoplasmic type than the 41-5A male sterile line.
