ABSTRACT

 

The use of advanced molecular technologies is one possible approach to understand their diversity. A study was undertaken to evaluate forty two rice genotype including six checks during kharif 2019. The result of the investigation was allele number was recorded for the five markers with an average of 2.6 allele per locus. Out of twenty five markers 12 markers showed highly PIC value. However, UPGMA cluster diagram mean of 67% level of similarity showed forty two accessions into 10 distinct clusters. Maximum cluster II had 13 genotypes followed by cluster IV, X, III and IX consisting of eleven, six three and two genotype respectively. Population structure analysis population inferred ancestry, 10 pure accessions were assigned to subgroup SG1 whereas 30 pure accessions were assigned to subgroup SG2 and two lines were assigned to admixture (AD). It was observed that the genotypes of subgroup 1 have brown planthopper resistant, whereas the genotypes of subgroup 2 have high yielding.

Keywords    Genetic diversity, Rice genotypes, SSR marker, Marker trait association.
