摘　　要：对南川百合(Lilium rosthornii Diels)、青岛百合(L.tsingtauense Gilg)、山丹(L.pumilum DC.)和岷江百合(L.regaleWilson)等4种野生百合进行了染色体数目观察和核型分析。结果表明,核型除山丹为3A外,其余3种材料核型均为3B。核型公式分别为:南川百合2n=2x=24=4m(4SAT)+2sm+6st+12t;青岛百合2n=2x=24=8m(4SAT)+2sm(2SAT)+14t;山丹2n=2x=24=2m(2SAT)+6sm(2SAT)+4st(4SAT)+12t;岷江百合2n=2x=24=2m(2SAT)+2sm+6st+14t。核型不对称系数分别是81.68%、76.09%、80.34%和82.26%。其中,南川百合和青岛百合为国内首次报道。The karyotype analysis of four Lilium species,L.rosthornii Diels,L.tsingtauense Gilg,L.pumilum DC.and L.regale Wilson,were studied in the experiment.The results indicated that the karyotype of L.tsingtauense was 3A,that of others were 3B.The karyotype formula was 2n=2x=24=4m（4SAT）＋2sm＋6st＋12t for L.rosthornii,2n=2x=24=8m（4SAT）＋2sm（2SAT）＋14t for L.tsingtauense,2n=2x=24=2m（2SAT）＋6sm（4SAT）＋4st（4SAT）＋12t for L.pumilum,2n=2x=24=2m（2SAT）＋2sm＋6st＋14t for L.regale.As·k% was 81.68%,76.09%,80.34%and 82.26% respectively.The karyotype of L.rosthornii and L.tsingtauense was domestic reported for the first time.
