Three festulolium (x Festulolium braunii) cultivars, Felina (fescue type), Paulita (ryegrass type), and Evergreen (ryegrass type : already marketed), were compared in yield and feeding characteristics with advancing growth of the first crop in Morioka (northeastern Japan) for 4 years from 2001 to 2004. The dry matter yields of the first crop were similarly high in Paulita and Evergreen for 4 years while those of Felina tended to be lower than the other cultivars. Fiber contents appearing in organic cell wall (OCW) and low-digestible cell wall (Ob) fractions increased with advancing growth in every variety. The increases in the fiber contents of OCW and Ob with advancing growth were higher in Felina than in the other 2 varieties. From these results, Felina is suitable for the fiberous herbage production, and for regions where the processing season of the first crop usually suffers unstable weather. On the other hand, Paulita is suitable to the high-nutritious herbage production for dairy cows. In conclusion, farmers should select the most suitable cultivars of festulolium for their necessity in feeding characteristics.
