Vegetative propagation lines were bred by tissue culture in vitro using immature leaf segment.Calli grew rapidly and vigorously on MS medium containing 2,4-Dling/L and KT 0.sing/L and BA ling/L with the callus induction rate of 89. 9%.MS medium supplemented with 2,4-D 0.88mg/L and BA 1.73mg/L was suitable for adventitious shoot induction.The maximum shoot induction rate reached 13. 21%.Shoots rooted quite well on MS medium with no hormones.The propagation coefficient in 250days was 3787.
