ABSTRACT

Forty diverse genotypes of Spanish bunch groundnut were evaluated during kharif 2017 for variability studies. The genotype TCGS-1847 registered higher mean values for pod yield per plant, kernel yield per plant, harvest index, shelling per cent, number of mature pods per plant, number of primary branches per plant and desirable low specific leaf area at 60 DAS. The estimates of PCV were higher than the estimates of GCV for all the characters. Moderate GCV and PCV values were observed for pod yield per plant, kernel yield per plant, number of mature pods per plant, dry haulms yield per plant, hundred kernel weight and hundred pod weight. Moderate heritability coupled with moderate genetic advance as per cent of mean was recorded by number of primary branches per plant, hundred pod weight, hundred kernel weight and dry haulms yield per plant.
