摘要 [目的]调查都匀及其相近生态环境中的野生茶树资源,挖掘和培育本地优势茶树品种。[方法]通过资源调查和扦插试验选择出了具有不同物候特性的高产优质原生茶树品系。[结果]在同一立地和相同气候条件下,不同无性系的腋芽萌动期不同,最早的在2月19日开始萌动,最晚的到3月25日才开始萌动。芽叶数与芽叶重呈极显著正相关,其相关系数为0.8682。芽叶分枝数的方差分析与F检验结果表明,都匀毛尖原生茶树不同无性系(品种)的芽叶分枝数差异极显著。无性系都匀67、都匀12、都匀70、都匀15、都匀63和都匀79的芽叶分枝数显著高于其他66个无性系,分别为57.667、44.667、38.500、37.333、36.500和34.500。[结论]筛选出了6个高产优质原生茶树品系,即都匀79、都匀49、都匀48、都匀21、都匀67和都匀42。 [Objective] The purpose was to investigate the wild tea resources in Duyun and its similar ecological environments and find and cultivate native dominant tea varieties. [ Method I The native high-yield and good-quality tea strains with different phonological characters were selected out through resources investigation and cutting experiment. [ Result ] In the same place with same climate condition, the budding dates of axillary buds of different clones were different. The earliest started to germinate on Feb. 19th and the latest did not germinate until Mar. 25th. The flushes number showed extremely significantly positive correlation with flushes weight and their correlation coefficient was 0. 868 2. The results of variance analysis and F-test on flushes branch number showed that there was extremely significant difference among the flushes branch numbers of different clones (varieties) of native tea trees of Duyun Maojian tea. The flushes branch numbers of clones Duyun67, Duyunl2, Duyun70, Duyunl5, Duyun63 and Duyun79 were significantly higher that of the other 66 clones and they were 57. 667, 44. 667, 38. 500, 37. 333, 36. 500 and 34. 500 resp. [ Conclusion] Six native high-yield and good-quality tea strains were selected out and they were Duyun79, Duyun49, Duyun48, Duyun21, Duyun67 and Duyun42.
