Genetic variability and components of variance in biparental mating populations of okra (Abelmoschus esculentus (L.) Moench)

Abstract

Studies on genetic variability and components of variance in four biparental mating populations of okra revealed high PCV, GCV for the traits like number of branches per plant, number of fruits per plant and fruit yield per plant, indicating greater scope for selection. Population P1 exhibited high PCV, GCV, heritability, genetic advance for most of the yield attributing traits, followed by P4 population. Other two populations P2 and P3 did not exhibit much variation for yield and related traits. Populations P1 and P4 exhibited highest between and within family variance for yield related traits, indicating potentiality of these cross combinations to release variability and provide ample scope for selection. Similarly P1 and P4 populations showed low narrow sense heritability indicating the predominance of non additive variance for number of fruits per plant and fruit yield per plant
