Abstract:
Background: Genetic variability is a necessary requirement for crop improvement programmes in order to generate high yielding varieties by estimating various genetic parameters such as components of variances, genotype and phenotype coefficients of variability, heritability, and genetic advance. The present investigation was aimed to estimate genetic variability in terms of variance components, heritability and genetic advance in the groundnut genotypes.Methods: During kharif 2020 thirty groundnut genotypes for ten characters were investigated to estimate genetic variability for pod yield and component characteristics. The investigation conducted at Oilseed Research Station, Latur. Results: Analysis of variance revealed existence of quite substantial differences among the genotypes for all the characters examined. The genotypes viz., ICGV00189, ICGV0213 and ICGV00202 demonstrated high mean performance for pod yield and its element features viz., number of mature pods per plant, kernel yield per plant, hundred kernel weight and sound mature kernel. High heritability coupled with high genetic advance as per cent of mean was recorded by the kernel yield per plant, pod yield per plant, number of mature pods per plant and hundred kernel weight making sure that these characters are under additive genetic control and consideration of these traits for the improvement will be lucrative and may rapidly contribute to increase pod yield in groundnut cultivars.
