摘要：
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 13 days in different plants, with duration of stigma receptivity upto 3 days. The protogynous plants produced normal viable pollen but had low seed set on selfing and high fertility index (proportion of seed set on cross pollination compared with that due to self-pollination) confirmed self- incompatibility in the protogynous plants.
