【摘要】 1975年在中国萝卜（Raphanus sativus L.）上发现雄性不育株后,采用测交、连续回交和父本株自交的方法,已先后育成了77-01A（白皮）,7416A（绿皮）、64A （红皮）、01-11A（绿皮）等不同类型的雄性不育系,用于F₁的种子生产。在测交过程中,发现不同品种对雄性不育性的保持能力差异显著。 我们的研究结果表明,萝卜雄性不育性的遗传属于核、质互作控制类型,细胞核内有两对ms基因,雄性不育系的基因型为Sms₁ sm₁ sm₂ ms₂,保持系的基因型为Nms₁ ms₁ ms₂ ms₂。初步证明,国内的48A、4-01A、青A、7416A等雄性不育系的基因型是相同的。根据以上研究结果,提出了萝卜雄性不育系的转育方案。更多还原

【Abstract】 Since the male sterile plant of Chinese radish （Raphanus sativus L.） was found in 1975, several male sterile lines of 77-01A （white rind）, 7416A （green rind）, 64A （red rind）, 01-11A （green rind） etc. in different types have been developed in succession by means of test cross and backcross and seefing of paternal plant and used to produce seeds of F₁ In the process of the test cross, the different maintaining ability of male sterility has been found among diverse varieties.It is concluded that inheritance of male sterility of Chinese radish is controlled by the genic interaction from both cytoplasmic and nucleus genes. There are two pairs of of ms genes in the nucleus. The genotype of the male sterile is Sms₁ms₁ms₂ms₂, and the maintenance line Nms₁ms₁ms₂ms₂. It is preliminarily verified that some radish male sterile lines of 48A, 4-01A, 7416A, etc. in China have the same genotype. Based on the experimental results mentioned above, a breeding project for the development male sterile line of Chinese radish has been proposed.更多还原
