Description
Through the lower U.S. Gulf Coast, lack of forage production during the typically mild cool season is a major limitation to beef cattle production. The combination of cool temperatures, occasional frosts, and low rainfall in peninsular Florida limit growth of warm-season forage species during the cool season. Temperate forage cultivars have failed to provide dependable cool-season forage, with the perennial species even failing to survive the typically hot, humid, occasionally waterlogged summer conditions of the Gulf Coast Spodosols. Early forage plant screening in Florida (McCaleb and Hodges, 1958) and more recent research in Alabama (Hoveland et al., 1974) have indicated potential for Phalaris germplasm in J:his environment. Recent screening of selected cultivars of reed canarygrass (Phalaris arundinacea) and hardinggrass (Phalaris aquatica var. stenoptera) at Ona, Florida (27° 26'N latitude 81° 55'W longitude) on an Ultic Haplaquod (Spodosol) soil resulted in survival of only a single clump of plants from one cultivar, Auburn reed canarygrass. A series of evaluations of this germplasm was conducted. In addition, the USDA Phalaris germplasm collection of 590 accessions was screened.
