Technical Abstract: Napiergrass or elephantgrass (Pennisetum purpureum Schumach) is a tall C4 grass that is used throughout the world as a forage crop. Breeding efforts at the University of Florida and with USDA-ARS at Tifton, GA produced high yielding cultivars (Merkeron) and breeding lines during the 1980’s. Yields have been reported as high as 40 Mg ha-1yr-1 in Florida. Merkeron had significantly higher yields than switchgrass cultivar Alamo over 6 years and at three locations in Georgia. A nursery with approximately 100 napiergrass plant introductions were evaluated for phenotypic traits related to biomass production and cell wall composition. Genetic variability was also assessed via AFLP analyses. A substantial range was found among accessions for leaf and stem neutral detergent fiber (NDF) and acid detergent fiber (ADF). The dendrogram constructed from AFLP analyses show clustering of accessions by country as well as significant heterozygosity within accessions.
