Variability Studies for Yield, Yield Attributes, Water Use Efficiency and Quality Traits in Groundnut (Arachis hypogaea L.)

Abstract

Thirty genotypes of groundnut were studied during kharif, 2017 to estimate variability, heritability and genetic advance for twenty two characters contributing to yield, water use efficiency and quality. Analysis of variance revealed that there was a significant variation among the genotypes for all the characters studied. The characters number of immature pods per plant, number of mature pods per plant, kernel yield per plant, number of pods per plant, number of pegs per plant, total free amino acids and pod yield per plant exhibited high GCV and PCV indicating ample amount of variation among the genotypes. High heritability coupled with high genetic advance as per cent of mean were recorded for the characters plant height, number of pegs per plant, number of mature pods per plant, number of pods per plant, kernel yield per plant, carbohydrate content and total free amino acids indicating the preponderance of additive gene action in expression of these characters and selection would be effective for improvement of these characters.
