Abstract

The research work was carried out at Dry land farm, Regional Agricultural Research Station (RARS), Tirupati during Kharif, 2022 comprising of thirty genotypes and genetic parameters viz., genetic variability, heritability (broad sense) and genetic advance as per cent of mean were estimated for ten characters. Analysis of variance showed that there were significant differences for all the ten characters studied indicating the presence of variability among the genotypes. Among all the characters studied, phenotypic coefficient of variation (PCV) was greater than the genotypic coefficient of variation (GCV) suggesting that the environment strongly influenced these characters. Pod yield plant-1 and Kernel yield plant-1 exhibited high PCV and GCV values (>20%) indicating that these traits can be considered for direct selection which leads to genetic improvement. Pod yield plant-1, kernel yield plant-1, 100 pod weight, 100 kernel weight and kernel length were governed by additive gene action which indicates selection of these traits is rewarding as they recorded higher estimates for both heritability (>60%) and high genetic advance as per cent of mean.

Peanut, Genetic variability, Heritability, Genetic advance

Conclusion

The higher estimates of GCV and PCV were found for Pod yield plant-1 and Kernel yield plant-1 which make these particular traits appropriate for selection. High heritability combined with high genetic advance as per cent of mean were recorded for Pod yield plant-1, kernel yield plant-1, 100 pod weight, 100 kernel weight and kernel length indicating the dominance of additive gene effects and hence direct selection can be used to enhance these traits.
