摘　　要：利用染色体组型分析进行种和种质资源的识别是一种有效的手段。本文利用Gemisa C-分带方法对三个卷班组百合南川百合(L.rosthornii)、川百合(L.davidii)和金佛山百合(L.jinfushanense)根尖染色体进行了研究。南川百合的带型公式为:2n=24=10C+8CL+2L+2N+2,川百合的带型公式为:2n=24=4C+2CI^++2I+6I_++ 2I^++2I_+T^++2T_++2CNT_++2,金佛山百合的带型公式为:2n=24=4C+4CI+4CI_++4I_++2I^++2I_++2I_+T^++2。通过Gemisa C-分带方法不但可以很好的区分各种的各条染色体,而且可以很好的区分这三个卷瓣组野生百合。It would be one of a efficient way for the identification of different plant species by genome chromosome analysis. The chromosomes from root tips ofL. rosthornii, L. davidii and L. jinfushanense, respectively, were analysised by Giemsa C-banding approach. The results indicated that the C-banding karyotype of the three species were 2n=24=4I＋8CI＋ ＋2I＋＋6I^＋ ＋2I^＋T＋ ＋2I＋T^＋, 2n=24=4C ＋2CI^＋ ＋2I ＋6L ＋2I^＋ ＋2I＋T^＋ ＋2T＋ ＋2CNT＋ ＋2 and 2n=24=4C ＋ 4CI＋4CI＋＋4I＋＋2I^＋＋2I＋＋2I＋T^＋＋2, respectively And the three wild lilies of sect. Used in this research were well distinquished dur to their different C-banding karyotypes. In this research we would have a suggestions that chromosomes from one species should be clearly identified based on Giemsa C-banding analysis.
