Abstract:: To promote the propagation efficacy of Hippeastrum，bulb cutting and tissue culture were studied for new cultivars by ‘Suhong’ and ‘Fengche’.The results showed that the reproduction rate and the growth rate of baby bulb after 5 months of ‘Suhong’ were bigger than ‘Fengche’.Baby bulb from bulb cutting was used in tissue culture.For two cultivars，the optimized disinfection program was disinfect baby bulb with 75% alcohol for 30 seconds，0.1% mercuric chloride 18 minutes and saturated calcium hypochlorite 20 minutes.After disinfection quarter cutting was used to cut baby bulb.This system had the highest reproduction efficacy and the lowest pollution rate.
