Abstract: In order to establish high-efficiency alfalfa genetic transformation system,the influence factors of Agrobacterium-mediated transformation system were studied. The callus and adventitious bud of alfalfa were induced by culturing leaves as explants in 8 different kind of medium,named M1-M8, respectively. The results showed that M7 medium(MS+1 mg/L 2,4-D + 2 mg/L CH + 0.25 mg/L KT + 2 mg/L agar) was the best one which can induced the much more ammount of callus and adventitious bud of alfalfa than others. The results showed that the most suitable conditions for kanamycin was 75 mg/L; OD600 of agrobactium concerntration value for 0.45-0.6.
