Synopsis

The genotype ICGV-99171, ICGV-98089, ICGV-97100, Baidehi, ICGV-00440, and B-4 performed better under drought condition tolerance with high pod yield. Hence, it is suggested that these genotypes could be grown under regions of limited rainfall. These lines may be used as parents in breeding program for developing drought tolerant groundnut cultivars. The results indicated that genotype ICGV-91074, ICGV-88473, ICGV-92173, B-4, Rajashri, ICGV-91104 and ICGV-98089 had lower level of Cercospora leaf spot disease incidence. Genotypes ICGV-91074, ICGV-98089, ICGV-92173 and ICGV-88473 produced higher pod yield and also had lower Cercospora leaf spot incidence. Genotypes ICGV-91104, ICGV-92173, B-4 and ICGV-91074 produced higher haulm yield and had the lower Cercospora leaf spot incidence. This study indicated that development or selection of tolerant/ resistant genotypes against leaf spot disease should be based on their level of disease incidence. Therefore, potential source of genetic resistance to this disease exist for selection among genotypes used in this study. Pod yield showed highly significant positive association with days to maturity, haulm yield and pod length.
