To investigate the variety characteristics of fodder rice, we did cultivation test about 10 varieties and on container and rice fields about heading date, growth, yielding ability, beta-carotene content, sugar content, and fermentation quality. As a result, the change of the heading date caused by transplanting date was large on normal variety Bekoaoba, small on later varieties. Whole dry matter production (t/10a) in yellow-ripe stage was highest Kusanohoshi was 2.5t, then Hokuriku 193 was 2.2t, Leaf star was 2.1t. An ear dry matter production (t/10a) in yellow-ripe stage was highest Hokuriku 193 was 1.0t, then Kusanohoshi and Bekoaoba was 0.9t. Beta-carotene content was 99-187 mg/kg at dry matter in milk-ripe stage, and average was 122 mg/kg, 59-143 mg/kg in dough-ripe stage, and average was 99 mg/kg, 43-100 mg/kg in yellow-ripe stage, and average was 69 mg/kg. There is some possibility of a way of beta-carotene contents shift from milk-ripe to yellow-ripe stage. Sugar content in the yellow-ripe stage was 1.0-5.6% in dried in 10 varieties. Chuugokushi 198 was highest, next Hamasari was. There was a strong relationship between the sugar content in fresh matter production and V2-SCORE(r=0.8899, p0.01).
