摘　　要：[目的]筛选大理低海拔地区规模化发展生态抗逆性强的优良核桃品种。[方法]采用群众荐优和实地调查相结合的方法,对云南大理低海拔地区188棵不同树龄(不小于15 a)的核桃树进行调查。[结果]经预选、初选、复选和决选,最终选出3株低海拔地区生态抗逆性核桃优良单株。单果重为7.6~10.3 g,壳厚为0.73~0.96 mm,出仁率为51.09%~62.46%。各决选优株果实成熟期较漾濞大泡核桃早。[结论]核桃品种表现为成熟早这一价值特性,在大理低海拔核桃生产中有较高的推广应用价值。[Objective] Select of superior walnut varieties with high ecological stress resistance in Dali. [Method] The 188 trees of different ages （ not less than 15 a） of the walnut tree in Dali of Yunnan were surveyed by method of the people commend and on-the-spot investigation. [ Result ] Ultimately selected 3 trees of ecological resistance in low altitude areas of walnut fine plant though qualifying, the primaries, check and runoff. The fruit weight was 7.6 - 10.3 g, the shell thickness was 0.73 - 0.96 mm, kernel rate was 51.09% - 62.46%. The runoff superior trees of fruit maturity than the Yangbi bullae early. [ Result] Walnut varieties showed the value of early maturity, which has a high value in the promotion of low altitude walnut production in Dali.
