Description
Hybrid pennisetum is an interspecific hybrid between pearl millet (Pennisetum americanum) and napier grass (P. purpureum). The combing of good characteristics of these two species by hybridization was reported (Cheng, 1984). The hybrids are triploid, 2n = 21, and propagated vegetatively. Thus a fertile hybrid would offer opportunities for seed production and forage improvement through hybridization. 2n gametes has been used recently as an alternative method to chemical treatments in a breeding program. The objectives of this investigation were to search for triploid hybrid pennisetum which would produce 2n pollen and to determine the cytological and histological origin of 2n pollen.
