Technical Abstract: Thirteen soybean [Glycine max (L.) Merr.] lines developed for forage production and five check cultivars developed for grain production were compared for forage quality at Ames, IA. Plants were grown in 76-cm rows and samples were collected every other week. Samples were separated into leaf, stem, and pod. Forage quality was measured using NIRS. The average leaf IVDMD, NDF, and ADF of forage soybeans were similar to those of the check cultivars, 716 g kg**-1, 302 g kg**-1, and 204 g kg**-1, respectively. Stem NDF, ADF, and ADL of forage soybeans tended to be lower than those of the adapted cultivars, 'Pella-86' and 'Kenwood'. The stem IVDMD, NDF, ADF, and ADL of the highest yielding forage line, OR 14-13-2, were 478 g kg**-1, 661 g kg**-1, 552 g kg**-1, and 102 g kg**-1, whereas those of the highest yielding grain cultivar, 'Sherman', were 506 g kg**-1, 651 g kg**-1, 545 g kg**-1, and 100 g kg**-1, respectively. The pod of OR 14-13-2 was less developed and the forage quality tended to be lower than that of 'Sherman'. Based on their forage quality and their biomass yield, forage soybeans have potential for use as an annual forage.
