Abstract


Late leafspot fungal disease caused by Phaeoisariopsis personata is widely prevalent in transitional belt of Karnataka state causing extensive defoliation and yield loss in groundnut. Fifty four known foliar disease resistant germplasm accessions were evaluated for late leafspot disease resistance and productivity for three years. Seven germplasm accessions, namely, PI 259747, ICG 7882, VG 78, VG 101, CS 16, GBFDS 272 and GBFDS 273 were found to be superior to other accessions for resistance, as well as , yield potential, but all these accessions were either late to mature or possessed undesirable pod and seed features making them unsuitable for direct utilization. However, these resistant accessions can be used in the breeding programmes aimed at developing high yielding varieties possessing resistance to late leafspot coupled with acceptable agronomic and pod /seed features.
