| Abstract: | 4 alfalfa （ Medicago sativa L. ） varieties were studied and synthetic evaluated onwinter survival rate, reviving stage, plant height, growth speed,regeneration speed,branchnumber, fresh yield,stem/ leaf during 2005 -2006. The Correlation between the factors ofcomponent yield and quality were analysed using grey rele- vancy and decision making method ofwith weight information of Fuzzy Mathematics, and meanwhile comprehensive evaluation modelwas founded using grey relevancy：ψ=0.1767ζ1＋0.1759ζ2＋0.1567ζ3＋0.1754ζ4＋0.1757ζ5＋0.1395ζ6（ ζ1 = Plant height, ζ2 = Growth speed, ζ3 = regeneration speed, ζ4 = Branch number, ζ5 = Stem/leaf, ζ6 = Fresh yield）. Through account of comprehensive evaluation model Gannong No. 3had good complex character and superiority. |
