Abstract
An experiment was conducted in Karnataka, India, during 2000 kharif season on 548 groundnut genotypes were screened for resistance to stem and pod rot (Sclerotium rolfsii [Corticium rolfsii]). None of the genotypes showed immune reaction. On the other hand, 339 accessions recorded an incidence of less than 10%, which were categorized as highly resistant. A total of 150 genotypes were moderately resistant and 53 were moderately susceptible. Only R8808, a genotype released for general cultivation was highly susceptible for stem and pod rot incidence. A total of 50 genotypes from the highly resistant category were selected and further evaluated against S. rolfsii under field conditions with artificial inoculation of S. rolfsii. Ten genotypes, 3 belonging to Virginia bunch (A. hypogaea var. hypogaea; TCG 1525, P1269710, NCAc 38), and 2 belonging to Virginia runner (A. hypogaea var. hypogaea; Haryanawadi, ND 8-2), 4 belonging to valgaris (A. hypogaea var. fastigiata; SS 34, VRR 472, Tai son (Jewel Nut) and P1268559 (NCAc 10121)) and 2 belonging to Spanish (A. hypogaea var. vulgaris; NCAc 18019 and RR5290) were highly resistant to stem and pod rot pathogen of groundnut
