摘要
对从国内各地引入清水地区的20个核桃品种(系)的树体特性、坚果经济性状、抗白粉病、抗越冬抽条、抗冻害特性和丰产性进行了7 a的观察研究。从适应性、丰产性、树体特性和坚果品质4个方面,用加权平均法对参比品种(系)进行了评价。结果表明:元丰、香玲、丰辉、辽4可作为清水地区的主栽品种;扎343和阿7可以适当发展;中林5可作为集约栽培的授粉品种,鲁光可作为林果兼用型品种来发展;中林1是抗寒育种的良好种质资源。
Canopy growth character, economic characters of nut, powdery mildew resistance, anti-sprouting and living through the winter, freeze injury resistance and productivity in 20 walnut cultivars or clones introduced from domestic had been observed and researched for 7 years in Qingshui County, Gansu province. Adaptation, productivity, canopy growth and nut quality in these cultivars or clones were evaluated by the method of weighted average. The results showed that Yuanfeng, Xiangling, Fenghui and Liao 4 could be planted as major cultivars in Qingshui; suitable scale of Za 343 and A 7 could be developed; Zhongling 5 could be planted as fertilizing variety in intensive cultivation of other cultivars (clones); Luguang could be planted for wood and nut; Zhongling 1 could be taken as fine germplasm resource for selecting and cultivating anti-cold varieties.
