| Abstract: | A wild ecotype of Elymus nutans was evaluated under alpine grassland conditions at Luqu county for three years. The results showed that the plant can grow for 128 days and wintering rate was 91% under the local environments. The herbage dry matter yield for the first, second and third year was 3170, 2453, and 2 560 kg/ha respectively. It is concluded that the Elymus nutans is a suitable variety for local environment. |
