This experiment was carried out to select the best adaptable varieties of Tall fescue in mountainous pastures of Taekwalyon area. The evaluation was based on the data of varietial differences in the dry weight of plant@W) and yield components of the 2nd growth. Nine varieties of Tall fescue examined were Barcel, Barvetia, Demeter, Enforcer, Forager, Fuego, Johnstone, Safe and Stef. And, the final cutting times were Sept. 30 ($C_1$), Oct.14 ($C_2$),Oct. 28 ($C_3$), and Nov. 11($C_4$). The reults were summarized as follows: 1. Barcel and Forager with many tillers per plant(NT) showed a high dry weight of plant@W) of the 2nd growth. 2. The dry weight of plant(DW) of the 2nd growth indicated significantly positive correlation with the number of tillers per plant(NT), but there was not significant correlation with the dry weight of tiller(WT). 3. The maximum dry weight of plant@W) of the 2nd growth was obtained at $C_3$(28 Oct.). 4. The dry weight of the 2nd growth showed an inverse relations with the dry weight of the 1st growth as affected by various final cutting time in growth period of autumn.
