A survey was conducted for collar rot disease incidence in southern Karnataka showed that Tumkur district recorded highest collar rot disease incidence of 14 percent followed by Chamarajanagar (8.50%) whereas Kolar recorded least disease incidence of 3.3 percent in Kharif. During summer 3.3 percent disease incidence was observed in Davangere district. Collar rot of groundnut pathogen was isolated by following standard tissue isolation method and the culture was identified through morphological and cultural characters. Pathogenicity was proved by blotter paper technique and sick pot method and the culture was compared with original culture. Among sixty four genotypes screened for collar rot, five genotypes viz., ICG 1994, ICG 2734, ICG 4749, ICG 13856 and ICG 7190 showed moderately resistant reactions. K-6 recorded least percent disease incidence (1.0 %) with highest pod yield of 10.5 q/ha compared to control TMV 2 with more disease incidence (2.30 %) and less pod yield of (7.7 q/ha).
