Abstract
By using partial regression analysis,14 varieties of alfalfa,including the introduced Canadian cultivar Algonquin,domestic mainstream varieties Baimu 202,Baimu 371,Gannong 5,Longdong purple alfalfa,and non-mainstream varieties Chal-lenger,Adina,Aurora,Ice Chaser,Big Galaxy,MF 4020,Jinneng 5010,Ladino,and Dryland,were used as experimental materials to clarify the quantitative relationship between forage yield and agronomic traits.The results showed that:(1)In the partial re-gression model,R=0.960,R2=0.922,and the partial regression model constructed with 8 independent variables explained 92.2%of the forage yield,indicating that the regression model was reliable.(2)The partial regression equation between forage yield and agronomic traits was established as:Y=9.821-0.008 X1-0.271 X2+0.366 X3+0.039 X4+0.002 X5+0.090 X6-0.838 X7-1.185 X8.The study concluded that the two main agronomic traits affecting alfalfa forage yield were internode length and stem node number.关键词
