Gene action in bhindi

Abstract

Estimates of components revealed that both additive and non-additive type of gene actions were operating for all three characters. Number of fruits per plant showed predominantly additive gene action while days to flower and plant height showed non-additive gene action. Dominance was found to be acting in the direction of earliness, tallness and greater number of fruits per plant. Asymmetrical distribution of positive and negative alleles wiu observed for all the characters in all the generations. Days to flowering and number of fruits per plant were controlled by one to three groups of dominant genes while it was four to fiive for plant height. Overdominance was observed for all the three characters.
