Abstract

Competitive ability of pollen parents involving ten restorers, three maintainer lines and thirty hybrids were studied at gametophytic and sporophytic level. Three pollen parents (R X-13, R IV-83 and R-857) recorded more than 80 percent pollen germination and more than 50 um pollen tube length ten minutes after incubation in pollen germination media. This indicated differential reaction in pollen viability of the parents at the gametophytic level. This was reflected in high self-fertility percentage in the hybrids involving these three pollen parents at the sporophytic level. Identification of competitive pollen parents at the gametophytic level and its utilization in developing pollen mixture hybrids in lieu of hybrid mixtures is of practical significance in getting higher yields in sunflower.

Keywords: gametophytic, sporophytic, pollen competition
