Indica Genetic Constitution and Genetic Diversity Analysis in Maintainer Line of Dian type Japonica Hybrid Rice

In this research, we analyzed the Indica genetic component ratios and genetic diversity of 231 maintainer line materials of Dian-type Japonica hybrid rice from Rice Research Institute of Yunnan Agricultural University with 23 insertion/deletion (InDel) polymorphic markers screened. We found that indica genetic component ratios ( Fi ) of all the materials were low and Fi ≤ 0.25. The percentage of 0 RRI-YAU > East China > Overseas > other places of Yunnan > CAAS > YAAS.
