(一) 关于水稻“三系”育性遗传的研究,一般认为,雄性不育性受细胞核、质里的育性基因所控制,并将此分为孢子体不育与配子体不育两大类型。近年来对野败三系育性控制作了大量遗传分析。兹将部分所得结果简要地列于表1。 从表1,结果来看,多数研究者认为水稻雄性不育性受两 (1) Studies on the fertility inheritance of “three lines” in rice are generally believed that male sterility is under the control of the fertility genes in the nucleus and quality of the rice. This is divided into two major types of sporophyte infertility and gametophytic infertility . In recent years, a lot of genetic analysis has been done on the control of wild-type three-line fertility. Some of the results obtained are summarized in Table 1 below. From the results in Table 1, the majority of researchers believe that male sterility in rice is affected by two
