• Ecotypic Variation in Tripsacum dactyloides Evaluated in Texas

      Schliesing, T. G.; Dahl, B. E. (Society for Range Management, 1983-09-01)
      Eastern gamagrass collections (26) from throughout Texas, except the Trans-Pecos, and from southern Oklahoma (3) were evaluated in a common garden at Uvalde, Texas, to select an ecotype suitable for planting in central and south Texas. Four potential ecotypes existed among the collections with a fifth existing in collections from extreme southeast Texas. The characters of this latter type overlapped those of collections from north Texas making it less distinct from the others. Collections (Type C) from central and west Texas were superior to all others in forage production, crude protein, and chlorophyll content. Collections from near Baird and Bracketville were outstanding and further field evaluation is warranted.
