Using analysis method of the single grain milled rice amylose content, it has been carried out for the genetic studies of amylose content in 5 hybrid rice combinations. The results showed that the segregation ratio of 4 genetypes WxWxWx :WxWxwx : Wxwxwx : wxwxwx was 1 : 1 : 1 : 1 in one combination of hybrid rcie (7001S×P23DaLi), the segregation ratios of amylose content were all 3 : 1 in 3 combinations of hybrid rice, the other was not clear. The hybrid rcie purity tested by the analysis method of single grain milled rice amylose content and the rule selected the parents of the good quality hybrid rice were discussed.
