Studies on pollen storage procedure and opt. time of pollination were carried out in 2 Pennisetum americanum inbreds and their reciprocal hybrids. The viability of pollen was judged by the percentage of seed set on male sterile line Tift. 23-A. A considerable reduction in pollen viability with the pollen stored for 24 h at ambient temp. (89 deg F) was noted, while no significant differences in seed set were observed between fresh pollen and pollen stored for 1 day at 40 deg and 2 days at 58 deg with almost 100% RH. The pollen stored at 58 deg had greater longevity for 14 days than that stored at 40 deg , where considerable reduction in seed set was observed after the 4th day. No appreciable differences were observed with the pollination done at 1000 h and 1300 h, while reduced seed set was observed when pollination was delayed till 1700 h. The differences in storage capability of pollen of different genotypes and effect of maternal parent on pollen storage capability of hybrids were apparent
