摘要
以互不等位的半矮秆、正常高秆与隐性高秆水稻杂交，研究表明：隐性高秆由隐性的长节间基因ｅｕｉ所决定，除了ｅｕｉ基因之外，隐性高秆还含有ｓｄ１基因，ｅｕｉ与ｓｄ１相互独立．隐性高秆和有ｓｄ１基因的半矮秆杂交Ｆ２表现３半矮∶１高，而与非ｓｄ１基因的半矮秆杂交Ｆ２表现３对基因的互作．２个隐性高秆相互杂交表明它们携带的长节间基因是相同的．
Non allelic genes and their relationship among various semidwarfs, normal tall and recessive tall mutants in rice were studied. Results from F 1 and F 2 generations indicated that recessive tall was controlled by an elongated uppermost internode gene ( eui ). In addition, it carried a common semidwarf gene sd 1 which was non allelic to eui gene. F 2 segregation ratio of recessive tall hybridized to various semidwarfs with the same sd 1 gene showed a good fit to 3 semidwarf∶1 tall. However, some segregation ratio of F 2 generation showed interaction of 3 genes in the crosses of recessive tall with semidwarfs other than sd 1 gene. Two recessive tall mutants carried the same eui gene. It discussed the applications of eui gene in indica japonica hybrid rice breeding.
