Performance of Elephant Grass Biograss as In Vitro Breeding Result in the Highlands of Bogor Regency, West Java, Indonesia 1)Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD) Abstract Low productivity of ruminants is mainly caused by the limited availability of high quality forages. Therefore, it is a necessary to generate a new superior variety of forages that are easily planted, adaptable to dry land, high productivity, and yielded. Biograss as a forage is a prospective strain, as a result of in vitro breeding that has high productivity and quality. This research aimed to determine the productivity and quality of Biograss in the highland of Bogor, West Java compared to local Elephant and Odot grass. The results showed that the speed of growth of Biograss cuttings buds was not significantly different from the speed at which local elephant grass buds and odot appeared. The bud color of the leaf petals appeared reddish in Biograss while the local Elephant grass and Odot were green. The number of tillers and local Elephant grass were 3-5 tillers while the number of Odot tillers were 5-7 tillers. Fresh weight of Biograss and Odot was 40 kg resulted from without fertilizing urea treatment and 60 kg with fertilizing urea treatment. Meanwhile, fresh weight of local Elephant grass was 60 and 90 kg, respectively based on urea treatments. Proximat analysis showed that the highest crude protein content (PK) of the Biograss was 17.95% with the NDF and ADF value of 61.79 and 37.27%. Whereas PK of local Elephant grass was 15.38% with NDF/ADF value of 63.15 and 39.01%; and PK of Odot grass was 16.30 with NDF/ADF value of 33.64%.
