Technical Abstract: Common dallisgrass (Paspalum dilatatum Poir.) is an important forage grass in the southeastern U.S. Besides common, there are several other dallisgrass biotypes but little is known about their forage potential. Five apomictic dallisgrass biotypes (common, prostrate, Torres, Uruguaiana, and Uruguayan) were grown at College Station, Texas, and Baton nRouge, Louisiana, to learn more about their forage production, quality, an persistence. Torres and Uruguaiana biotypes did not persist at either location. In Texas, the forage yields of the common, prostrate, and Uruguayan biotypes were similar; however, in Louisiana, prostrate and Uruguayan produced significantly more forage than common because of its poor persistence. At both locations, there were not significant differences in mean CP, NDF, ADF, and IVTD for common, prostrate, and Uruguayan. Uruguayan and common were evaluated under grazing at Jeanerette, Louisiana, and the Uruguayan biotype was more persistent than common.
