Cv. 4Mott' dwarf napiergrass has unusually high forage quality for a tropical grass (Sollenberger et al., 1988). Mott has been hybridized with pearl millet, and four of the best triploid F, progeny were selected for comparison with Mott and other non-dwarf Pennisetums. This five year study compared the dry matter yield of seven lines of Pennisetum. and also measured in vitro organic matter digestibility (IVOMD), crude protein (CP) and neutral detergent fiber (NDF). The chromosome number of a triploid Fj^ hybrid was doubled and three of the hexaploid progeny were evaluated at the Beef Research Unit in 1988 and 1989. In general, the hybrids showed similar IVOMD to Mott, but had increased leafiness and lower fiber than the tall napiergrass varieties.
