Adaptability evaluation of 12 perennial forage cultivars in alpine region of Diqing

To select suitable perennial forages cultivating in alpine region of Diqing, the introduction adaptability of 12 perennial forage grasses was studied in this research, and the grey correlative degree analysis was used to evaluate the production performance of these 12 perennial forage grasses. The results showed that the order of production performance of 12 perennial forage grasses was Medicago sativa cv. Amerigraze401+Z > Cichorium intybus cv. Commander > Dactylis glomerata cv. Anmba > Lolium perenne cv.Yatsyn > Trifolium repens cv.Prop > Trifolium pratense > T. repens cv. Haifa > M. sativa cv. Eureka > M. sativa cv. WL-525 > Bromus willdenowii cv. Grasslands Matua > M. sativa cv. Hunterriver >Elymus sibiricus cv. Tongde. The production and adaptability of M. sativa cv.Amerigraze401+Z, Cichorium intybus cv. Commander, D. glomerata cv. Anmba, L. perenne cv. Yatsyn, T. repens cv. Prop, T. pretense and T. repens cv.Haifa were relatively better, which were preferred varieties used in establishing artificial grassland and modifying natural grassland in Diqing area.
