[Method] Media suppIemented with different combinations and concentrations of hormones were pre-pared for anther cal us induction, proIiferation, differentiation and regeneration. [Re-sult] MS＋1.0 m/L 2, 4-D＋0.5 mg/L 6-BA was the optimum medium for anther cal us induction. MS＋1.0 mg/L KT＋0.1 mg/L NAA was the optimum medium for cal us proIiferation. MS＋2.0 mg/L 6-BA＋0.3 mg/L NAA was the optimum medium for in-duction of adventitious buds. MS＋0.3 mg/L IAA was the optimum medium for root-ing of adventitious buds. The highest rooting rate was onIy 37.5 because induction of rooting was a difficuIt work. [Conclusion] The resuIts wiI provide references for outcross fertiIity and genetic improvement of eggpIant.展开更多
