鄂西地区核桃良种引种筛选初报

Preliminary Report on Screening of Improved Species for Juglans regia L.in Western Hubei

良种的调查筛选是林木引种驯化的一项重要的前期基础工作,笔者调查了北方核桃产区7 a生早实核桃品种(无性系)18个在鄂西地区栽培的抗病能力,调查了南方核桃产区10个核桃品种在鄂西地区栽培的抗寒能力,综合比较鄂西地区与国内核桃产区的气候条件,确定云南、河北、山东、辽宁核桃产区的辽宁一号、鲁光、香玲、元丰、中林、云杂系列品种为鄂西地区区域化试验的试验材料。建议开展不同品种在鄂西地区适生区域选择的系统研究。

Survey screening is an important basic work of the forest introduction and domestication in early stage. The authors surveyed the disease resistance of 18 clones of 7- year--old precocious Juglans regia L. varieties that introduced form the north Juglans regia L. producing area and the cold--resistant of 10 Juglans regia L. varieties that came from the south of China, which are planted in western Hubei. The varieties of Juglans regia L. ： Liaoning 1, Luguang, Xiangling, Yuanfeng, Zhonglin and Yunza series from Yunnan, Hebei,Shandong and Liaoling respectively are used regionlization test by integrated comparison between the weather condition of the western Hubei and others walnut producing area in China. In the end, the systematic research of choosing an adaptable region of different Juglans regia L. varieties is suggested.
