摘  要：
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%.
