利用高秆隐性水稻Grlc与几个矮秆籼稻杂交、回交,调查其F_2与F_1的株高表现。研究结果表明,高秆隐性水稻Grlc的株高性状受一对隐性主效基因控制,当其与Sd_1基因的矮秆籼稻杂交,F_2株高的高、矮秆分离比例为1:3,用隐性亲本回交F_1,高、矮秆分离比例为1:1。卡方测验结果一致。Grlc与Sd_1基因等位。 The high stalk recessive rice Grlc was crossed with several dwarf indica rice and backcrossed to investigate the plant height phenotype of F_2 and F_1. The results showed that the plant height trait of high stalk recessive rice Grlc was controlled by a pair of recessive major genes. When crossed with the dwarf indica rice of Sd_1 gene, the plant height and dwarf segregation ratio of F_2 were 1: 3, With recessive parent back F_1, high, short stalk separation ratio of 1: 1. Chi-square test results are consistent. Grlc and Sd_1 gene alleles.
