Abstract


Groundnut (Arachis hypogaea L.) is a legume crop, a member of the Fabaceae family cultivated for food and one of the cash crop across the world. Selected 10 genotypes viz., CO 7, ICGV 07222, VRI 6, VRI8, GPBD 4, VRI 3, Chico, Gangapuri, ICGV 91,114 and ICGV 93,468 varying in maturity duration from short to long were clustered at molecular level through SSR markers. The selected genotypes were clustered into four clusters by D2 analysis and six clusters through NTSys analysis, grouping the early maturing varieties and high yielding varieties, separately. The trait kernel yield per plant contributed the maximum towards divergence among the selected genotypes of 38.50% followed by hundred pods weight with a contribution of 12.6%. The analysis of SSR markers on 10 genotypes, the primer GM 2637 exhibited maximum number of alleles (7) with higher PIC value (0.79).
