Induced quantitative variation for yield and its components in okra [Abelmoschus esculentus (L.) Moench]

Highly significant variation was observed in mutagen treated okra populations as compared to their respective controls. Mean values of all the yield and yield atributing characters showed shift towords both the direction (positive and negative) in both the generations (M₂ and M₃) in all the genotypes. In general, the mean for various characters increased with the lower doses of mutagens in both the generations in all the genotypes. The magnitude of range and coefficients of variation (CV) in treated population was generally higher as compared to the control for all the characters under study in both the generations. The magnitude of variability declined from M₂ to M₃ generations. High genotypic and phenotypic coefficients of variation were observed for number of fruits/plant and yield/plant. High heritability with high genetic advance were found for yield/plant, plant height, and number of seeds/fruit in both the generation for all the genotypes.
