A protogynous line identified in Indian mustard was examined to study the interval of protogyny, stigma receptivity, pollen viability, fertility index and seed set. The results revealed that the protogynous interval was up to seven days in different plants, which showed stigma receptivity upto 3 days. The protogynous plants produced normal viable pollen but low seed set on selfing and high fertility index indicated self- incompatibility nature of the protogynous plants.
