The appearance characters of different walnut varieties were discussed,which provided basic data for breeding and cultivation management of walnut varieties in Lüliang area of Shanxi province.Eight years old varieties of Xiangling,Zha 343,Jinxiang and Zhonglin 1 were used as experimental materials,the quality traits of walnut and the main quantitative characters such as green fruit and nut three-path,economic characters and yield per plant of different varieties were compared and analyzed.The results showed that the main characteristics of the four varieties were oblong,shell more smooth,more yellow inner seed coat,kernels were full,easy to take kernels.Green fruit and nuts three diameter of Xiangling varieties were the largest,and the fresh quality of fruit,single fruit quality and kernel quality were better than the other 3 varieties,which was 59.93,23.69,11.42 g/per,respectively.The highest yield per plant of Xiangling was 3 140.50 g.In the correlation analysis,the mean value of three paths of green fruit was significantly correlated with fresh quality,single fruit quality and kernel quality,single fruit quality was significantly correlated with kernel quality,and kernel quality was negatively correlated with shell thickness.The Xiangling variety is more suitable to be planted and popularized in Lüliang area of Shanxi province.%探讨核桃不同品种坚果的外观性状,为山西吕梁地区核桃品种选育和栽培管理提供基础数据.试验以8年生香玲、扎343、晋香和中林1号品种为试验材料,比较分析核桃的质量性状及青果和坚果三径等主要数量性状,对不同品种的经济性状及单株产量进行探讨.结果表明,4个品种外壳特征主要是长圆形,壳多光滑,内种皮多为黄色,核仁均饱满,取仁易;香玲品种的青果和坚果三径均为最大,且青果鲜质量、单果质量与果仁质量均优于其他3个品种,分别为59.93,23.69,11.42 g/个;产量上,香玲的单株果仁产量最高,为3 140.50 g.相关性分析表明,青果三径均值与青果鲜质量、单果质量和果仁质量显著相关,单果质量与果仁质量显著相关,果仁质量与壳厚呈负相关.综合分析坚果外观性状得出,香玲品种更适宜在山西吕梁地区种植推广.
