ĐÁNH GIÁ ĐA DẠNG DI TRUYỀN MỘT SỐ MẪU GIỐNG LÚA THU THẬP TẠI LÀO BẰNG CHỈ THỊ PHÂN TỬ SSR

Genetic diversity is the diversity of gene segments between individuals of the same species and between different species; the diversity of genes can be inherited in a population or between populations. This study the genetic diversity and DNA fingerprinting of rice samples collected from Laos PDR were elucidated by using 22 SSR markers. There were ten SSR markers show that polymorphism and twelve markers was monomorphic. A total of 41 alleles were detected at 10 SSR marker loci with average 4,1 alleles per locus. With the genetic similarity coefficient of 0,79 the rice samples were grouped into 4 main clusters. As a result, the varieties VL27 and VL33 of the varieties were shown very similar to each other.
