【摘要】 [Objective] To study karyotype analysis of Lilium leucanthum (Baker) Baker in Shennongjia national nature reserve, so as to supply some cytological data for studying genetic diversity, origin and systematical evolution of Lilium leucanthum (Baker) Baker. [Method] Karyotype of Lilium leucanthum (Baker) Baker was analyzed by the conventional section method. [Result]The chromosome number was 2n=2x=24, and the basic chromosome number was x=12. Karyotype formula was K(2n)=24=4m (2SAT)+2sm +8st+10t, mainly consisting of terminal and subterminal chromosomes. Chromosome composition of relative length was 2n=24=4L+4M2+14M1+2S, whose karyotype asymmetric coefficient was 79.66% belonging to "3B" type. [Conclusion] The karyotype of Lilium leucanthum (Baker) Baker in Shennongjia national nature reserve belong to evolutionary type in systematic and evolutionary of family Liliaceae.
