Assessment of Variability, Heritability and Genetic Advance in Groundnut (Arachis hypogaea L.)

The present research, entitled “Assessment of Variability, Heritability, and Genetic Advance in Groundnut (Arachis hypogaea L.),” was conducted on 15 genotypes with 16 characteristics. The analysis of variance revealed that genotypic variation was extremely significant for all of the traits under consideration. Additionally, the phenotypic coefficient of variance was larger than the genotypic coefficient of variation in magnitude. Quantitative features include the number of pods and kernels per plant, days to bloom initiation, days to 50% flowering, and days to maturity, test weight, shelling percent, and kernel yield per plant showed high heritability indicating that the variation was caused by additive gene action. The correlation estimates provide a better understanding of yield components and studies on genotypic and phenotypic correlation coefficients of different traits help the plant breeder during selection.
