摘　　要：利用普通压片法对新铁炮百合(Lilium×formolongi)3个品种的染色体数与核型进行了分析。结果表明:(1)‘雷山1号’核型公式为2n=2x=24=4m+6sm(2SAT)+8st+6t;(2)‘雷山2号’核型公式为2n=2x=24=4m(2SAT)+2sm+10st+8t(2SAT);(3)‘雷山3号’核型公式为2n=2x=24=2m(2SAT)+8sm+4st+10t。三者核型均为3B型,其核型不对称系数分别为72.96%、77.39%和75.93%。The chromosome number and karyotype studied by squash method.The results indicated that the karyotype formula of three cultivars of Lilium × formolongi as follows：（1）The karyotype formula of＇Raizan 1＇was 2n = 2x = 24 = 4m ＋ 6sm（2SAT）＋ 8st ＋ 6t;（2）The karyotype formula of＇Raizan 2＇was 2n = 2x = 24 = 4m（2SAT）＋ 2sm ＋ 10st ＋ 8t（2SAT）;（3）The karyotype formula of＇Raizan 3＇ was 2n = 2x = 24 = 2m（2SAT）＋ 8sm ＋ 4st ＋ 10t.The three cultivars of karyotype belonged to 3B,asymmetry index（As.K%）were 72.96%,77.39%,75.93% respectively.
