Abstract

Analysis of genetic divergence of sixty four genotypes (39 new germplasm accessions and
25 advanced breeding lines) of groundnut revealed wide range of D2 values ranging between
4.52 and 27.75 suggesting the presence of considerable amount of genetic diversity in the
genotypes studied, which were grouped in to seven clusters where, cluster VII (28) was the
largest followed by cluster I (24) and cluster VI (4). Maximum inter cluster distance was recorded
between IV and VI representing wide divergence among these clusters. On the basis of intercluster
distance and cluster means the genotypes viz., ICGV-05033, ICGV-05052, PAFRGVT-
58, GG-20×ICGV-91114, ICGX-020063-F2-B1-SSD-P20-B1, ICGX-020055-F2-SSD-P37-B1 were
widely diverse therefore may be considered for future breeding programmes.
