TAILIEUCHUNG - Studies on genetic variability for yield, yield attributing traits, physiological and quality traits in groundnut [Arachis hypogaea L.]

An experiment was carried out to estimate the genetic parameters such as variability, heritability and genetic advance, for yield, physiological and quality traits in 30 genotypes of groundnut. The genotypic coefficient of variation for all characters studies were less than the phenotypic coefficient of variation indicating the interaction of genotype with the environment. High heritability coupled with high genetic advance as per cent of mean was observed for specific leaf area at 45 DAS, plant height, number of primary branches per plant, number of mature pods per plant, number of secondary branches per plant, 100-pod weight, 100-kernel weight, total soluble sugars, sucrose 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. High heritability with moderate genetic advance as per cent of mean was exhibited by the characters sound mature kernel per cent and harvest index. Moderate heritability coupled with high genetic advance as per cent of mean was exhibited by the characters viz., dry haulms yield per plant, pod yield per plant and kernel yield per plant suggesting that phenotypic selection can be used for improvement of these characters. | Studies on genetic variability for yield, yield attributing traits, physiological and quality traits in groundnut [Arachis hypogaea L.]
