Abstract
This study was conducted to select the promising varieties of alfalfa (va.) Venal, Ancho., P5444, DK120, DK125, Horizon, DK135, Luna and Kitawacaba at Daekwanryong branch(altitude 800m a.s.l.) and Namwon branch(altitude 450m a.5.1.) of National Livestock Research Institute Leaf width of alfalfa was broad in all varieties except fer Vernal, and DK125 was flowered the earliest of all varieties. Plant height of Luna was the longest, and winter hardness of P5444 was the greatest with 80.2% of all varieties. In Daekwanryong, dry matter(DM) yield of Luna was the highest and DM yield of vernal was the lowest among the varieties in Namwon. In both areas, dry matter yield ef P5444 was the highest of alfalfa varieties. In Daekwanryong, ADF and NDF concentrations of DK 120 were the lowest of all alfalfa varieties. In Namwon, ADF concentrations of Horizon was the lowest with 26%, and NDF concentrations of DK 125 and Horizon was the lowest with 40.8%. Crude protein concentrations of P5444, Luna and DK 120 were higher than that of different varieties in Daekwanryong and crude protein content of Horizon was the highest with 28.1% in Namwon. Average crude protein yield of both areas was the highest of P5444. The results of this study indicated that Luna, Horizon and P5444 would be the promising alfalfa varieties in Daekwanryong, Namwon and both areas, respectively.
