Genetic variability, heritability and genetic advance in some exotic genotypes of groundnut (Arachis hypogaea L.)

摘要

Thirty exotic groundnut genotypes collected from National Research Centre for Groundnut, Junagarh, Gujarat were used to study their performance, genetic variability, heritability and genetic advance for yield and yield contributing characters. Significant variations were observed for all the characters in all the genotypes used in the experiments. Higher phenotypic and genotypic coefficients of variations were observed for pods/plant, pod length, number of kernels/plant, kernel yield/plant, fodder/plant, harvest index and pod yield/plant. Characters like days to flowering, pod length, kernel length, 100-pod weight and dry matter/plant showed high heritability. The highest genetic advance as percentage of mean was recorded for kernel yield/plant, fodder/plant, harvest index and pod yield/plant.
