摘　　要：为培育滇橄榄栽培良种,在怒江流域开展滇橄榄优树选择及优树无性系测定。结果表明:在20株备选优树中决选8株滇橄榄优树,其平均单果质量14.9 g,可食率86.71%,果肉可溶性固形物含量16.81%,总糖含量2.38%,总酸含量3.64%,粗纤维含量2.89%,维生素C含量4.90 mg/g;连续3 a平均单位冠影面积果实产量3.16 kg/m^2;8个滇橄榄优树无性系早期树高、地径、冠幅、果实产量的差异均达极显著水平(P<0.01),P2无性系具有明显的早实丰产特性;单株结实量与地径生长极显著正相关(P<0.01),与冠幅显著相关(P<0.05)。In order to cultivate some superior cultivars of Phyllanthus emblica,selection and early clone test of P.emblica plus trees were conducted in the Nujiang River Basin.The results show that eight plus trees were screened out from the twenty candidate trees finally,and their average fruit mass,edible rate,soluble solids content,total sugar content,total acid content,crude fiber content,vitamin C content and average fruit yield per unit crown shadow among three years were 14.9 g,86.71%,16.81%,2.38%,3.64%,2.89%,4.90 mg/g and 3.16 kg/m^2,respectively.At early period,height,ground diameter,crown width and fruit yield were all significantly（P 0.01） different among the eight plus trees clones of P.emblica,and the clone P2 had obvious characteristic of early bearing and high yield.Fruit yield per plant was extremely significantly related with ground diameter（P 0.01）,and significantly related with crown width（P 0.05）.
