Molecular characterization of selected aromatic short grain genotypes of rice (Oryza sativa L.)

Abstract

Fifty four selected genotype accessions of short grain aromatic rice (Oryza sativa L.) along with three checks were molecularly characterized by 10 selected markers identified for aroma and present on chromosome number 8. This was carried out in MAS Lab, Dept. of Genetics and Plant Breeding, RRH Lab, IGKV, Raipur. The data were recorded for all 10 SSR markers by Jaccard’s similarity coefficient and Euclidean distance using NTSYS PC programme to study diversity among selected genotypes. Jaccard's similarity coefficient ranges from 0.40 to 0.99 with highest similarity coefficient between 5 groups at more than 0.99. Highest dissimilarity showed by Akbar badshah and Bassabhog from rest all of the genotypes. Total 57 rice genotypes taken under study were also divided into 5 main clusters, at 0.55 Jaccard’s similarity coefficient.
