摘　　要：In this paper, based on the DUS testing of new Lavandula spp., the differences and correlations of main phenotypic traits between Lavandula angustifolia and L. heterophylla were observed and analyzed. The results showed that the plant morphological traits of L. angustifolia were better than that of L. heterophylla, moreover, L. angustifolia exhibited relatively high adaptive capacity to the environmental conditions in introduction areas of north China. For the inflorescence, the ornamental traits of L. heterophylla were totally superior to that of L. angustifolia, especially in flower color diversity. It had obvious differences in both quantitative traits and qualitative traits between the two species, and these traits remained relatively stable in the growth progress. The correlation coefficients among the traits of two species were high, and the trait matching numbers at the 1% significance level of L. angustifolia were slightly more than that of L. heterophylla.基于薰衣草属新品种DUS测试的性状选择,对狭叶薰衣草(Lavandula angustifolia)和甜薰衣草(L.heterophylla)主要表型性状的差异性和相关性进行了观测与分析。结果表明:狭叶薰衣草的植株形态优于甜薰衣草,且更能适应北方的引种环境。在花序部分,甜薰衣草的观赏性状总体上优于狭叶薰衣草,具有更丰富的花色变化。两种薰衣草在主要的数量性状和质量性状上都表现出明显的差异性,并在生长过程中保持了相对一致的稳定性。两种薰衣草各性状之间的相关系数都很高,狭叶薰衣草在1%显著水平上相关的性状配对个数略多于甜薰衣草。
