Genetic diversity and population structure of 93 rice cultivars (lines) (Oryza sativa Xian group) in Qinba in China by 3 types of genetic markers

Abstract

The population genetic variation explained by SNPs was larger than that explained by SSRs. The gene flow of 93 samples used in this study was larger than that of naturally self-pollinated crops, which may be caused by long-term breeding selection of Indica rice in the Qinba region. The genetic structure of the 93 samples was simple and lacked rare alleles.
