Genetic Divergence Studies in some Indigenous Rice ( Oryza sativa L.) Germplasm of Northern Dry Zone of Karnataka using Simple Sequence Repeats (SSR)

Simple Sequence Repeat (SSR) among twenty-four rice genotypes, comprising of the land race (1), germplasm (11), INGER breeding lines (8) and Local cultivars (4) was characterized by 14 primers of SSR out of 14 primers, and 13 were polymorphic. The PIC value ranged from 0.076 (RM408) to 0.80 (RM212) with an average of 0.57 per marker. The simple matching similarity coefficient ranged from 0.30 to 0.96. The genotypes were grouped into ten clusters. At the genetic similarity of 85%, allelic variability among the SSR markers was high and sufficient to categorize rice genotypes into ten clusters formed through SSR, data revealed that the genotypes exhibit high genetic diversity since, very much useful in the breeding programme
