Studies on Genetic Variability, Heritability and Genetic Advance in Genotypes of Okra [Abelmoschus esculentus (L.) Moench]

Abstract

Genetic variability analysis on 29 genotypes of okra revealed high magnitude of genetic variability and high degree of transmission of majority of the growth, earliness and yield associated traits under study. High magnitude of genotypic coefficient of variation (>20%) for number of marketable fruits per plant, marketable yield per plant and yellow vein mosaic virus infestation indicated high degree of genetic variability offering great scope for selection of these characters. High heritability (>60%) coupled with high expected genetic advance (>20%) for number of marketable fruits per plant, marketable yield per plant and yellow vein mosaic virus infestation indicated the involvement of additive gene action and more chances of fixing by selection to improve such traits.
