Abstract:
Mung bean (Vigna radiata (L.) Wilczek) is an important grain legume in Asia. Simple Sequence repeats (SSR) are the variable in short tandem repeat of DNA bases, giving codominant markers, which can distinguish between homozygotes and heterozygotes. The study was conducted during the year 2016-2018 using randomized block design of experiment with three replications at Plant Breeding Farm of Annamalai University. Twenty greengram genotypes along with 10 SSR markers were utilized. Only one marker was diallelic producing two distinct alleles among the genotypes while two markers were mono-allelic showing a dominant allele pattern. The genetic distance estimated using DICE dissimilarity co-efficient indicated highest divergence of 0.8 between GG15 and GG17. The dendogram showed five apparent clusters based on marker allele distribution. This SSR marker YMV1 can be used to screen the large germplasm for YMV resistance.
