摘要： 采用染色体常规压片的方法，对渥丹百合(Lilium. concolor Salisb.)4个居群进行了染色体核型分析，结果表明，有斑百合BH27 (L. concolor var. buschianum Baker.) 和有斑百合BH41 (L. concolor var. buschianum Baker.)核型分别为2n=2x=4m(2SAT)+4st+16t(2SAT)和2n=2x=4m(4SAT)+12st+8t(4SAT)，黄花渥丹BH20(L. concolor var. concolor f. coridion Kitag.) 核型为2n=2x=4m(4SAT)+4st+16t(4SAT)，大花百合BH50 (L. concolor var. megalanthum Wang et Tang) 核型为2n＝2x=4m(4SAT)+6st(2SAT)+14t(4SAT)；其核型分类都属于3B型，但结构变异明显，主要表现在染色体相对长度、臂比、次缢痕数目及分布。

Abstract: The karyotypes of 4 populations of Lilium concolor Salisb. were studied. The results showed that the karyotypes of L. concolor var. buschianum Baker. (BH27) and L. concolor var. buschianum Baker. (BH41) were 2n=2x=4m(2SAT)+4st+16t(2SAT) and 2n=2x=4m(4SAT)+12st+8t(4SAT), respectively. The karyotype of L. concolor var. concolor f. coridion Kitag. (BH20) was 2n=2x=4m(4SAT)+4st+16t(4SAT) and that of L. concolor var. megalanthum Wang et Tang (BH50) was 2n＝2x=4m(4SAT)+6st(2SAT)+14t(4SAT). The karyotypes of all the 4 populations were 3B. There were a few variations in the karyotye formulas, relative length, arm ratio, secondary constitution number and its distributions among the 4 populations.
