Genetic diversity in Indian common bean (Phaseolus vulgaris L.) using random amplified polymorphic DNA markers

Abstract

Genetic diversity of twenty-six common bean (Phaseolus vulgaris L.) accessions of diverse geographical origin was studied using Random Amplified Polymorphic DNA (RAPD) markers. Fifteen out of forty four primers screened showed polymorphism across present set of genotypes. A total of 124 amplicons were scored using these 15 primers. Ninety five percent of the amplified products showed polymorphism, indicating fair amount of variation at the DNA level among these accessions. Cluster analysis delineated the genotypes in to four groups. © 2008 Prof. H.S. Srivastava Foundation for Science and Society.
