This experiment was conducted to evaluate the forage yield and quality potential of Festulolium braunii (Festuca pratensis Huds. $\times$ Lolium multiflotum Lam) as forage source in Korea. The experimental design was a split plot design with four replications from Feb. 1994 to Jan. 1996 at Hohenheim uniwrsity. Main plots were three forage species {Fesruca pratensis(Cosmos), Lolium mult~~orum(Lemtal) and Festulolium braunii(Pau1ita)) and subplots were three N levels (150,300 and 450kgha). No differences in dry matter(DM) yields were noted between Festulolium braunii and Lolium multj7orum, but DM yields for Festulolium braunii was 138 more than for Fesruca prafensis(P<0.01 ). Total DM yields over all species increased linearly with increasing N levels. The peak of DM yields over 2 years mean at 450kglha N levels were higher for Lolium mulriJotum(l5,724kg) than for Festulolium braunii(14,730kg) and for Festuca pratensis(l3,68 l kg) (P<0.01). OMD, ME, NEL and other minerals of Fesrulolium braunii were slightly higher and CP, Ca and Mg slightly lower than thsoe of Fesruca pratensis, but CP, OMD, NEL and minerals were absolutly higher for Fesrulolium braunii than for Lolium mulriflorum(P<0.01). It appears that Festulolium braunii has higher potential for improvement of the forage quality than Fesruca prarensis or Lolium rnulrijlorum. The content of CP, CF and minerals were increased, wherease OMD, ME and NEL were decreased in all species with increasing N levels. Yields of CP, DOM and NEL over 2 yean mean were increased in all species with increasing N levels. CP, DOM and NEL yields of Festulolium braunii were higher than those of Lolium multiflorum or Festuca pratensis(P
