Abstract:Inorder to screen suitable varieties of alfalfa(Medicago satioa L.)for planting in the semi-arid area of Hexi Corridor,this study measured and analyzed the production performance and nutritional quality of 12 introduced alfalfa varieties. The results showed that the hay yield of‘Nanmu 7O1’was the highest,with an annual hay yield of 2.08kg⋅m-2 ,significantly higher than other varieties( .P<0.05⋅ ;There was significant difference in the fresh to dry ratio of different varieties inthe same stubble ⋅P<0.05) ;The crude protein content of‘Nanmu 7O1’was relatively high,reaching 25.71% DM,significantly higher than‘Gannong 4∘ Zhongmu ,and‘Juneng(moisture tolerance)'( P<0.05) ; The variety with the highest relative feeding value and total digestible nutrients was‘Nanmu 701⋅ ,which was significantly higher than other varieties ( ;The hay yield was significantly positively correlated with plant height ( P<0.01⟩ ,CP was significantly positively corre latedwith fresh to dry ratio (P<0.05) ,and RFV was significantly positively correlated with branch number and fresh to dry ratio ( ⋅P<0.01⟩ ;Byusing the weighted membership function method to analyze the comprehensive production performance and nutritional value,it found that‘Nanmu 7Ol’performed well and was suitable for promotion and planting in the region.
