摘要
综述了近25年来水稻野败型细胞质雄性不育(CMS-WA)恢复基因的遗传及其分子标记定位研究进展.有学者认为,CMS-WA育性的恢复受1对基因控制;大多数研究者认为受2对基因控制,2对基因间互作方式有加性、重叠和显隐性上位作用,也有的认为2对基因是相互独立的;还有人认为受多基因控制或是一种质量-数量性状.在恢复基因分子标记定位方面,有学者发现为1对恢复基因,并将其定位在第10染色体上,也有定位在第7染色体上;发现为2对恢复基因的学者,将其定位在第1和第10染色体上,或定位在第7和第10染色体上,也有将2对恢复基因都定位在第10染色体上;发现为多对恢复基因的学者,有人鉴别出8个基因位点,其中2个Rf-3和Rf-4为主效基因,分别定位在第3和第4染色体上,6个微效基因分别定位在第1,2,5,6,10和第12染色体上;也有人将2个主效基因定位在第1和第10染色体上;还有学者发现为4个QTLs,其中一个主效基因Rf-10被定位在第10染色体上,3个微效基因分别定位在第1,第7和第11染色体上.
The researching development on genetics and loci of molecule marker for restoring genes of cytoplasmc male sterility of wild abortive（CMS-WA） were described. Researchers have been exploring the quantity and the way genes control the traits of sterility-restoring, Some scholars believe it is controlled by one gene, the others believe it is controlled by two genes, which had joint interaction, presenting the effect of additive, epistasis, and superposition. Also some scholars concluded the trait of sterility was a quality-quantity character. In the loci of restoring gene, some scholars found a pair of genes and located it on chromosome 10 and the other located it on chromosome 7. Some scholars found two pairs of genes and located them on chromosome 1 and 10 or 7 and 10, the other located both on chromosome 10. Of the scholars who found sterility restoring controlled by polygene, some found 8 loci, two of them, Rf-3 and Rf-4, are major genes, and located them on chromosome 3 and 4 respectively, six minor genes were located on chromosome 1, 2, 5, 6, 10, 12. Also some scholars located the two major genes on chromosome 1 and 10. Still some scholars found four QTLs, one of major genes, Rf-10 was located on chromosome 10, three minor genes were located on 1, 7 and 11 respectively.
