摘　　要：为给滇东北核桃品质的遗传改良提供材料,并为高寒山区及核桃冬春现象严重发生地区的核桃生产提供指导,按照坚果品质和丰产性状等选育指标,对滇东北地区丰富的核桃种质资源进行了优良单株的初选、复选和决选。经综合评定,共筛选出了昭鲁23、昭鲁31、昭鲁32、昭鲁45、昭彝03、昭彝07、昭阳2、会005、会027、东川03这10株优良单株,这些优良单株的平均树龄为40a,株产坚果20～40kg,平均单果质量13.49g,壳厚1.17mm,出仁率为54.55%。In order to provide materials for genetic improvement of walnut quality in Northeastern Yunnan and provide guidance for walnut production at cold areas, 10 superior trees in Juglans siggillata L. were selected from rich germplasm resources in Northeastern Yunnan through preliminary selection, multiple selection, final selection and comprehensive evaluation according to the selection standards of good quality and high yield. The 10 superior trees were Zhaolu 23, Zhaolu 31, Zhaolu 32, Zhaolu 45, Zhaoyi 03, Zhaoyi 07, Zhaoyang 2, Hui 005, Hui 027 and Dongchuan 03, respectively. Average age of the selected trees was 40 years old. Nut yield per tree was 20-40 kg. Average mass of single nut was 13.49 g. Shell thickness was 1.17 mm, and kernel percentage was 54.55%.
