Establishment of Molecular Identity Card of Elite Rice Resources

The genetic diversity studies in rice resources and the exploration and utilization of elite germplasm resources are the basis of improving varieties of rice and germplasm innovation.The genetic diversity of 27 elite rice germplasm resources were analyzed,the genetic similarity coefficients of them were calculated,and these rice resources were clustered using 24 pairs of SSR primers recommended in the files of the Chinese Ministry of Agriculture rice variety identification(DNA fingerprint method),then the fingerprint of each parent germplasm was constructed and a set of corresponding molecular identity cards were built,and new formulation methods to facilitate the distinction of each germplasm resource were explored.
