Sex modification in female cultivars like Kajli and S36 by foliar application of GA3 at 100, 200 and 400 ppm concentrations was studied. The height of the plants increased and the number of days decreased with increasing concentration of GA3. Gibberellic acid, at all concentrations decreased the production of female and increasing of male and mixed flowers respectively. The pollen viability is moderate and seed set percentage decreased with increasing concentrations of GA3.
