Evaluation and selection of 28 alfalfa varieties in the Hinggan League
The experiment aimed to study the production performance and nutritional quality of 28 alfalfa varieties to select suitable alfalfa varieties for planting in Hinggan League area of Inner Mongolia.The trial analyzed the production performance,nutritional quality,and feeding value of the introduced alfalfa varieties,classified the alfalfa varieties by the square Euclidean distance complete linkage method,and conducted a comprehensive evaluation using the membership function analysis method.The results showed that the fresh grass yield and hay yield of Zhungeer were the highest,at 14 533.33 kg/hm2 and 3 633.33 kg/hm2,respectively.Caoyuan No.2 had the highest crude protein content(20.27％),the lowest neutral detergent fiber content(44.95％),the lowest acid detergent fiber content(38.40％),and the highest relative feeding value(122.10),but its fresh grass yield and hay yield were relatively low,at 9 083.33 kg/hm2 and 2 516.67 kg/hm2,respectively.Longmu 806 had the lowest crude protein content(15.27％),the lowest crude ash content(6.16％),the lowest crude fat content(1.34％),the highest neutral detergent fiber content(58.78％),the highest acid detergent fiber content(50.98％),and the lowest relative feeding value(77.85),but Longmu 806 had relatively high fresh grass yield and hay yield,at 13 733.33 kg/hm2 and 3 450.00 kg/hm2,respectively.The 28 alfalfa varieties could be grouped into three groups,the first group was the optimal group,the production performance and nutritional quality are relatively high,there were 17 alfalfa varieties.The second category for high yield group,the production performance is relatively high,but the nutritional quality as poorer,there were four alfalfa varieties.The third group was the high quality group,the nutritional quality was relatively high,but the production performance was poor,there were seven alfalfa varieties.The study indicates that Kangsai,Baimu 202,and Liangmu are suitable for promotion and planting in Hinggan League area of Inner Mongolia.
