摘要: 水稻亚种间杂种不育性是一种普遍现象,但其遗传基础复杂.目前在亚种间杂种不育性遗传上,不同研究者的结论不尽一致,即使对亚种间杂种不育性主要表现为雄性不育还是雌性不育也存在争论.本文对证明水稻亚种间杂种存在和不存在雌性不育的研究进行了综述与分析,从中可以看出无论是认为水稻亚种间杂种不育性表现为雄性不育还是雌性不育的结论都有一定的片面性;尤其是Sano证明基因座S-5不存在的研究存在较大的缺陷.因此,水稻亚种间杂种雌雄配子败育对小穗育性影响的大小有待进一步研究。
Abstract:Hybrid sterility in the Fl populations of wide crosses in rice is a common phenomenon but the genetic basis of the sterility is complex.Whether male or female sterility is the main cause of the hybrid sterility remains controversial.This paper summarized the experiments which support or negate the existence of female sterility,analyzed the experimental ideas and inference methods of these experiments,especially Sano' s;and concluded that the conclusion that the hybrid sterility is only caused by male or female sterility is a one - sided view,therefore attention should be paid to the genetics of both female and male sterility.
