Abstract:
The present investigation entitled, “Genetic Diversity Studies in Greengram (Vigna radiata (L.) Wilczek)” was undertaken to study the nature and extent of variability present among the genotypes for quantitative characters in greengram and grouping genotypes into various clusters. The knowledge of genetic diversity helps in identification of germplasm, gene stock and establishment of core collection. Genetic diversity is one of the basis of parent selection for breeding programme. Genetic diversity among parent, which is heritable, is a prerequisite for any successful breeding programme. The proper choice of parents in breeding programme is of paramount importance. Generally, plant breeder selects the parents on the basis of phenotypic divergence but for effective breeding knowledge of genetic diversity amongst the parents with respect to characters which are to be improved is essential. All the forty genotypes of greengram were grouped into eight clusters. Cluster II had maximum number of 20 genotypes, Cluster I, Cluster IV and Cluster V had 5 genotypes, Cluster VII had 2, while Cluster II, VI and VIII had single genotype each respectively.
