摘　　要：对云南栽培茶树茶(Camellia sinensis)、阿萨姆茶(Camellia sinensis var.assamica)及野生茶树大理茶(Camellia taliensis)资源的10个形态性状分别进行统计分析,结果显示,茶、阿萨姆茶和大理茶主要性状有明显差异,多样性指数平均为阿萨姆茶(1.873)>茶(1.868)>大理茶(1.766)。阿萨姆茶形态多样性指数最高,大理茶最低。说明云南茶树种质资源具有丰富的形态多样性;对云南主要茶区阿萨姆茶茶树种质资源的10个性状数据进行多样性指数分析,结果表明,3个阿萨姆茶茶区(普洱茶区、版纳茶区、滇西茶区)间形态多样性指数差异较小。Diversity analysis of 10 traits of tea plant germplasm resources from Yunnan were conducted based on morphological data. The re- sults showed that the morphological diversity was high among assessed materials, and the average value of diversity index showed Camellia sinensis vat. a,ssamica （ 1. 873 ） 〉 Camellia sinensis （ 1. 868 ） 〉 Camellia taliensis （ 1. 766）. Morphological diversity index was the highest in the cultivated Camellia sineruis vat. assamica and the lowest in the wild tea plants C. tallensis. Diversity analysis of 10 traits of cultivated tea plant var. assamica was conducted based on morphological data. The results demonstrated that there was non-significant variation among the tea plant var. as.samica from Puer, Xishuangbanna and Dianxi districts.
