Abstract

Yield and nine components of yield were studied in seventeen semi spreading groundnut varieties. The coefficient of variability, heritability, genetic advance and phenotypic correlations were worked out. High heritability estimates combined with high genetic advance was observed in number of flowers, yield of pod. 1000-pod weight and 1000-kernel weight. The height of main stem had high heritability value with moderate genetic advance as well as positive and strong association with 1000-pod weight and kernel weight.
