Description Groundnut (Arachis hypogaea L.) is an important annual oilseed legume crop, valued as a rich source of proteins,
minerals and vitamins. It is an unpredictable crop due to its underground pods development. For improvement
of yield in groundnut direct selection is often misleading. The knowledge of existing variability is essential for developing high yielding genotypes in groundnut. An experiment was conducted with 43 gronudnut genotypes at college of agriculture, Vijayapura, UAS Dharwad, during kharif, 2013-14 to study the genetic diversity for IDC
resistance related traits, yield and its component characters. The estimates of GCV and PCV were high for net plot
yield (22.722 and 47.915) and low heritability with moderate GA as % mean was observed for net plot yield
(22.5 and 22.197). The genotypes were highly diverse for IDC resistance and classified into 18 clusters. The
diversity among the genotypes measured by intra-cluster & inter cluster distance in the present investigation was
adequate for improvement of groundnut genotypes for IDC resistance by hybridization and selection. Seventeen
clusters found to be solitary these can be used as promising parents for hybridization programme for obtaining high heterotic response for IDC resistance and thus better sergeants in groundnut.
