Abstract

This study was carried out to select superior soybean cultivars for forage production for soybean forage production in Jeju. The results obtained are summarized as follows; Eighteen soybean cultivars were grown from May 11 to September 11 in 2002 in Jeju to select superior cultivars for forage production. Days to flowering was shortest(58 days) for Seokryangkong and Keunolkong, and longest(93 days) for Danpaheukdu. Days to flowering for other cultivars ranged from 65 to 69 days. Pureunkong and Namhaekong had greater heights(129.3 and 124.6 cm, respectively) while Keunolkong, Hwaeomkong and Seokryangkong had shorter heights. The number of branches per plant was gratest for Sobaekkong, Manrikong, Pungsankong, Kwangankong and Geumgangkong. The number of leaves per plant was geatest for Sobaekkong, Iksankong and Namhaekong. Rueunkong and Jangmikong had thicker stems. Fresh forage yield was greatest for Iksankong, Sobaekkong and Namhaekong(39.5, 39.3 md 38.0 MT/ha respectively). DM yield of forage was featest for Baekunkong, Hnrunkong and Danpaheukdu. Danwonkong, Dawonkong, Seokryanfong and Pungsankong had ueatest forage crude protein content. Duyukong and Kwangankong had featest forage crude fiber content. Jangmikong and Keunolkong had feater crude fat content, while Sobaekkong and Kwangankong had greater crude ash content. Namhaekong, Seokryangkong, Keunolkong and Jinpumkong had greater NFE contents ranging 40.0 to 43.5 and TDN was featest in Keunolkong, Danpaheukdu, Namhaekong and Seokryangkong had greater NFE contents ranging from 59.8 to 60.9%. The best cultivars in Jeju for forage soybean appear to be Namhaekong, Danpaheukdu md Baehukong on the basis of crude protein, TDN, and dry matter yields.
