| Abstract: | The genetic diversity of 18 rice varieties from northeast China and 13 rice varieties from Japan were investigated by 20 phenotypic traits and SSR assay with 40 pairs of primers. The results showed that 82 phenotypic variation and 108 alleles were detected. With an average of 2.54 alleles on every locus the phenotypic variation and alleles in northeast China were 72 and 103, respectively, and 63 and 94 were respectively with an average of 2.32 alleles on every locus in Japanese varieties. Genetic variation among different varieties varied greatly and among different groups varied slightly. Genetic diversity of varieties in northeast China was much higher than those in Japan, and 94.7% of the alleles from Japanese varieties were included in the varieties from northeast China. The available specific alleles were already very limited in the varieties from Japan and can not meet the rice breeding requirements for northeastern China. |
