Abstract The cultivated Groundnut or peanut is an annual self pollinated legume crop. It is the major oilseed crop in India and in Andhra Pradesh. The genotypes viz., TCGS-1865 showed higher performance for pod yield per plant and number of mature pods per plant. TCGS-1868 performed better for shelling per cent, kernel yield per plant and 100 kernel weight. The genotype, TCGS-1858 had short stature plant type. Greeshma came to flowering early and also matured in early. TCGS-1875 had recorded more number of primary branches per plant. The genotype, TCGS-1873 had shown low incidence of 2.0% followed by TCGS-1862 (2.1%) for stem rot. Hence these genotypes were found as promising donors and these genotypes could be exploited for improvement of yield and its contributing characters in the breeding programme as donors. High heritability was recorded by days to 50% flowering, days maturity, sound mature kernel per cent and rust incidence. Higher genetic advance as per cent of mean was recorded for number of secondary branches per plant, number of mature pods per plant, 100 pod weight, 100-kernel weight, late leaf spot disease, rust disease, stem rot, kernel yield per plan and pod yield per plant indicating that the effect of environment is least in expression of these characters.
