| 摘 要： | 在本研究中,首先在二十个籼粳亚种四倍体水稻F1代中筛选出高结实杂交组合:Dur/Sg9912 (命名为PSR120),然后在田间随机取样的200多株PSR120F2代植株,并考察其结实率。用统计软件分析结实率,结果表明,多倍体水稻F2结实率变异大,分布不对称。

| Abstract: | In this paper,we first screened a polyploid recombination Dur/Sg9912 (donated as PSR120)which with high seed-setting from twenty indica-japonica polyploid hybrids. More than two hundred PSR120 F2 plants were selected randomly for investigation of seed-settings. Analyses the seed-setting, it shows that the seed-setting of F2 of polyploidy paddy rice PSR120 is in a large variation and asymmetry distribution. |
