Performance of 12 Medicago sativa species in Shengyang was compared, indexes of main characters were analyzed, and the results showed that: green hay yield between all varieties tested had significant difference, while there were no significant difference of stem/leaf ratio and fresh/dry ratio. Fresh/dry ratio and stem/leaf ratio were negatively correlated with great significance, enabling (fresh/dry) ratio to be estimated based on stem/leaf ratio; conversely, stem/leaf ratio could also be estimated based on fresh/dry ratio; green hay yield and average growth speed had very significant positive correlation, forage yield might be estimated based on the growth speed of Medicago sativa.
