Abstract

Pollen grain embryogenesis in anther cultures of Brassica juncea cv. PR-45 was considerably enhanced by treating the donor plants with 4 mll-1 (v/v) of ethrel or delayed sowing of the donor plants, the latter treatment being superior. The anthers derived from plants sown about two months after the normal sowing period showed 18% androgenesis as compared to 3.5% in the control.
