Abstract
The effect of gibberellic acid and kinetin on seed set was studied aft er applying these hormones on flowers before and after pollination in wheat-barley crosses. The maximum seed set obtained in UP 2121 x Jagra ti was 2.5 per cent when gibberellic acid was applied 5 min after poll ination followed by another application after 24 hr. In the reciprocal cross it was maximum (11.86 per cent) with the same treatment. Multip le pollinations and application of a mixture of hormones resulted in a higher percentage of seed set than control in both the crosses.
