Technical Abstract: Common dallisgrass (Paspalum dilatatum Poir.) is an apomictic, pentaploid forage grass that is grown throughout the southern U.S. Besides Common, there are several other dallisgrass biotypes, but little is known about their forage production and quality characteristics. To determine the yield, forage composition, and persistence of three hexaploid dallisgrass biotypes (Uruguayan, Uruguaiana, and Torres), clipping studies were established at College Station, TX, and Baton Rouge, LA. At both locations the Uruguaiana and Torres biotypes failed to persist. At CS the forage yield of the Uruguayan biotypes was similar to Common dallisgrass, while in LA the Uruguayan biotypes produced significantly more forage due to the poor survival of Common. No significant difference in mean CP, NDF, ADF, and IVTD were observed among the hexaploid accessions or between the hexaploid accessions and Common dallisgrass.
