Abstract

The pollen viability of pearlmillet fertility restorer line (K560 D230) was tested during two consecutive summer seasons. The vishility of pollen was judged in terms of seed setting on the male sterile line (MS 5141A). The pollination with fresh pollen and stored upto 2 hours resulted in good seed setting. Also the stigma receptivity of the male sterile line was tested by starvation and then by open pollination. Starvation upto two days resulted in better seed setting and after which the seed set declined.

Keywords: Hybrid pearlmillet, Pollen viability, Stigma respectivity.
