The purpose of this paper is to develop a system for tissue culture and rapid propagation of two amental lupins, Minaretie and Russell Prize. In view of screening out the better explant regeneration and suitable culture medium, through adding hormone 6-B A, NAA and 2,4-D into MS and B5 basic culture medium, a series of experiments were carried out with the shoot tips, leaves, leaf petioles and stems from the asepsis seedling. The results showed that the shoot tips had favorableness on the rapidly propagation; MS+6-BA 0.5g·L-1 for first generation, the induction rate of Minaretie and Russell Prize was 90.5% and 95.86% respectivdy; Minaretie had the highest propagation index (6.35) on MS+6-BA 0.5 mg·L-1+NAA 0 mg·L-1+GA 30.8 mg·L-1+AC 2 g·L-1, but Russell Prize had the highest propagation index (7.24) on MS+6-BA 0.5 mg·L-1+NAA0.15 mg ·L-1+GA3 1.0 mg·L-1+AC 0.5 g·L-1; 1/2 MS+NAA 0.25 mg·L-1 was the best rooting medium. The ratios of getting roots of Minaretie and Russell Prize were 94.78% and 96.32%, respectively.
