树莓（Rubus corchori f olius Linn ．）系一种高钾低钠类天然保健果品，营养、保健和药用价值较高。通过分析高寒地区光、热、水、土资源对树莓的生态耦合性，探讨了树高、地径、果实纵径、横径和果实内种子粒数等5个性状的变异程度，旨在为高寒地区良种选育和引种栽培提供理论依据。结果表明，树莓能迅速适应环境的变化，生态耦合性较强；家系间树高、地径、果实纵径、横径和种粒数量等性状存在一定变异，平均变异系数分别为15．87％、19．94％、16．46％、17．93％和32．92％。以果实性状为主要评价指标，兼顾生长势、遗传表现和鲜食舒适度，确定Y H F02为优良家系，其果实较大，舒适度最佳，应用前景广泛。

Rubus corchorifolius were a kind of the natural fruits which it could provide the low potassium and high sodium in improving health ,and it has a high nutritional ,hygienical ,and medicinal value .In order to provide the theoretical basis for the breeding ,introduction and cultivation in the cold area ,We analyzed the variant degree of quantitative characters about the height ,diameter ,fruit vertical diameter ,fruit width ,and its seed numbers base on discussing the ecological coupling on light ,heat ,water and soil resource of Rubus corchorifolius in extremely cold areas .The results showed that its ecological coupling were stronger ,and it more able to quickly adjust to environ‐mental changes .There were certain difference on the quantitative characters among the different families ,and its av‐erage coefficient of variation were 15 .87% ,19 .94% ,16 .46% ,17 .93% and 32 .92% respectively .According to the main evaluation indicators of the berry character ,and considering its grow th vigor ,genetic performance and comfort of fresh food ,YHF02 was to be regarded as excellent individual ,and its fruit were larger .
