| 摘 要： | 对新铁炮百合17个株系主要性状的变异进行了观察，结果表明，所观测的大部分性状在株系间存在显著或极显著差异，根据选育的主要性状，综合水平较好的株系为1、2、6、8、9、10、17。同时对17个株系进行聚类分析，表明株系间遗传距离差异大，最大的为51.418，最小的仅2.949，根据遗传距离将17个株系分为3大类，认为该百合分离群体具有较丰富的遗传变异性，是新品种选育的良好基础群体。 |

| Abstract: | The variations of some important traits among 17 lines of Lilium formolongi were studied. The result showed that the variances of most traits observed were statistically significant or very significant. The line 1,2,6,8,9,10 and 17 had better synthetic traits. The genetic relationships of 17 lines were also studied. The clustering analysis results showed that the genetic distances among lines were of difference, the maximum 51.418, the minimum 2.949. The 17 lines were divided into three groups according to genetic distances. The lines studied here were plentiful in genetic variations and suitable for breeding. |
