南新不育系,系我院用C系统不育材料与粳稻品种“新西兰”杂交育成。该材料已回交到第五代,不育性能稳定;经初测,出现了具有恢复和部分恢复的籼粳稻品种;杂种第一代的优势明显。“三系”已经配套,目前正在转育和小量繁殖试验。一试验目的和意义我国水稻雄性不育利用的研究,进展极快,成绩显著,已赶上和超过世界先进水平。但是,在理论和实践上,尚有许多问题。在理论上,对水稻雄性不育的遗传实质的认识,一直在激烈的争论。一种意见认为,水稻雄性不育是由细胞质、细胞核里的不育基因所控制。在基因理论的基础上,提出了二型学 South new sterile line, Department of our hospital C system sterile materials and japonica varieties “New Zealand” hybrid breeding. The material has been back handed to the fifth generation, sterile performance is stable; After preliminary testing, there is recovery and partial recovery of indica and japonica varieties; hybrid first generation has obvious advantages. The “three lines” have been matched and are currently being transplanted and small-scale breeding trials. A test purpose and significance of China’s use of male sterile rice research, the progress is extremely fast, the result is remarkable, has caught up with and surpassed the world’s advanced level. However, there are still many problems in theory and practice. In theory, there has been a heated debate over the genetic reality of rice male sterility. One opinion is that male sterility in rice is controlled by the cytoplasm and the sterile gene in the nucleus. On the basis of gene theory, proposed the second type
