[Objective] To explore the effects of different seed colors on seed germination and callus induction of Leymus chinensis.[Method] According to the color of mature seeds of Leymus chinensis,they were divided three color types,namely,pale yellow,yellow and black.Their seed germination and callus induction were observed.[Result] The pale yellow Leymus chinensis seeds had higher germination rate(32.5%) and rate of callus induction(28.5%).Based on the results of the TTC method and electrical conductivity,the seed viability was decreased with the deepening seed color.[Conclusion] The study laid the foundation for establishing highly efficient plant regeneration system of Leymus chinensis.
