摘 要 ：利用Giemsa C-带方法对宜昌百合（Lilium leucanthum(Baker) Baker）进行研究。结果表明：宜昌百合（L. leucanthum）的染色体数目为2n＝2x=24，单套染色体的条带总数目为21条。其带型公式为：2n＝24＝6C+2CI+2I+2CI⁺+2CI⁺+4I⁺+2I⁺+2T⁺+2I+S。宜昌百合（L. leucanthum）每条染色体上都显示出显著的特征带，且带纹的深浅差异明显。宜昌百合（L. leucanthum）的强带主要集中在着丝点及附近区域。通过Giemsa C-带方法可以将宜昌百合（L. leucanthum）的每条染色体区分开。

Abstract:The chromosomes from root tips of Lilium leucanthum(Baker) Baker were analyzed by Giemsa C-banding. The result showed that, the karyotype is 2n=2x＝24, the banding number of one genome was 21.The C-banding karyotype would be: 2n＝24＝6C+2CI+2I+2CI⁺+2CI⁺+4I⁺+2I⁺+2T⁺+2I+S. Significantly different C-banding points were shown on each chromosome. Most of the strong bands of L. leucanthum were distributed on the centromeric regions of the chromosomes. Each chromosome of L. leucanthum(Baker) Baker can be distinguished by Giemsa C-banding.
