Abstract: In 2003, the USDA NRCS Jamie L. Whitten Plant Materials Center, Coffeeville, MS will be releasing a new cultivar of eastern gamagrass for forage and biomass production, soil stabilization, and water quality and wildlife habitat improvement. The cultivar NRCS accession 9062680, will be named Highlander. The source material for this cultivar was collected in Montgomery County, TN. Chromosome counts indicate that it is a tetraploid (2n = 72). Highlander was tested at various locations throughout the aoutheastern and south central United States and it provided average annual dry matter (DM) forage yields of 16,456 kg ha-1 on a 45-day cutting schedule. Tests at Coffeeville have shown potential DM yields of 13,6850 kg ha-1 when plants were cut once annually for bioenergy fuel production. This cultivar has shown resistance to a devastating root and crown rot that killed mature plants of other eastern gamagrass accessions at Coffeeville. Tentative identification of the causal organisms showed that species of Pythium and Rhizoctonia were present and may have acted together as a disease complex. Highlander seed should be available on the commercial market for the 2005 planting season.
