STUDIES ON THE RICE NOVEL CYTOPLASM OF MALE STERILITY──COMPARATIVE STUDIES ON GENETICS OF STERILITY OF NOVEL RICE CYTOPLASMIC MALE STERILITY MAXIE A WITH ZHENSHAN 97A

    摘要
  • 摘要: 采用套袋自交结实率和自然结实率为主, 花粉育性和田间目测整株育性为辅的综合性状, 判定新型细胞质雄性不育系马协A以及它与明恢63的杂种F1、F2和BF1的植株育性, 并以野败型珍汕97A作对照, 比较研究了其不育性的遗传规律。结果表明, 马协A与珍汕97A不育性的遗传均由两对基因控制, 但新型细胞质雄性不育系马协A两对基因的作用方式与珍汕97A不同。前者F2群体的育性分离符合9:3:3:1的比例, BF1符合1:2:1的比例; 后者相应群体则符合12:3:1和2:1:1的比例, 两对基因间表现为显性上位。斯米尔诺夫检验也表明马协A/明恢63和珍汕97A/明恢63的F2群体的结实率频率分布差异显着(P<0.01).并讨论了细胞质雄性不育的遗传机理及分子基础。

     

    Abstract: Maxie Aand Zhenshan 97Awere crossed with Minghui 63.Their hybrids were backcrossed with Maxie Band Zhenshan97Brespectively.The F1, F2 and BF1 plants were sown and identified by means of bagged seed setting rate, natural seed setting rate, pollen fertility and individual-observed fertility in field.The genetics of sterility of Maxie Aand Zhenshan 97Awere comparatively studied.The results show that their Sterility is controlled by two pair genes. But the intertiction of those genes in Maxie Ais different from that in Zhenshan 97A, which appears to be dominant epstasis. The fertility segregation of the former comforms with geneticical ratio of 9:3:3:1 in F2, 1:2:1 in BF2, the later, 12:3:1 and 2:1:1 in the respective populations. Smirnov tests indicate the frequency distribution of seed setting ratio in F2 of Maxie A/Minghui 63 and Zhenshan 97A/Minghui 63 is different(P< 0.01).The genefic mechanism and molecule basis of cytoplasmic male sterility are discussed.
