This study was conducted to evaluate forage yield and quality for the accessions derived from inter-specific cross between wild and cultivated soybeans. First of all, three soybean lines (W02, W09 and W11) derived from PI483463 (Glycine soja) x Hutcheson (G. max) and three cultivated soybeans (Daewon, Pungsannamul and Bosug) were evaluated to determine forage yield and quality at the R2 (full bloom stage), R4 (full pod stage) and R6 (full seed stage) stages of development. Based on forage yield and quality, R6 was determined the optimal harvest stage to provide forage of high quality and adequate quantity for animals in both lines derived from G. soja × G. max and cultivated soybean.

Second, 25 selected lines from PI483463 × Hutcheson or S-100 (G. max) × PI483463 and four common seed-type cultivars (Bosug, Pungsannamul, Taekwang and Hutcheson) were evaluated to determine forage yield and quality at stage R6 in 2010. Hutcheson had the highest forage yield with 24.7 t/ha in fresh weight (FW) and 6.6 t/ha in dry matter (DM) among cultivated grain soybeans. A selected line W11 had highest FW (25.7 t/ha) and DM (6.2 t/ha) among G. max × G. soja selections. Five selected lines (W02, W06, W11, W13 and W18) had similar forage yield compared to Hutcheson. Generally the 25 selected lines derived from G. soja × G. max had thinner main stems and branches which lead to get more edible forage than cultivated soybeans. When selected lines were evaluated for their feed quality as per forage grade by American Forage and Grassland Council, 23 lines had a crude protein with more than 19%; 9 lines had a neutral detergent fiber below 40%; 23 lines had an acid detergent fiber below 31%; 24 lines had a digestible dry matter of more than 65%; 13 lines had a dry matter intake of more than 3.0%, and 17 lines had an relative feed value higher than 151 or were equivalent to prime grade. And all of 25 inbred lines were equivalent to Grade 1. Therefore, inter-specific cross between G. max and G. soja will be an excellent way to develop forage soybean with good yield and quality.
