摘　　要：为综合评判湖北省十堰市核桃坚果品质的优劣,为十堰核桃育种筛选打下基础。在野外调查的基础上,收集了12个十堰核桃品种,对其坚果外形特征(纵径、横径和侧径)、单果重以及主要营养成分进行了分析。结果表明,十堰3号外形一致性程度较差,十堰1号的给人们感觉良好。十堰10号的平均单果重最大,达到11.82 g;十堰7号出仁率最高,高达58.01%,与其它十堰核桃的出仁率差异显著;十堰5号可溶性糖含量最高达到4.04%;十堰3号的可溶性蛋白含量最高达到97.05 mg/g;十堰13号总蛋白含量最高达到232.67 g/kg;十堰3号粗脂肪含量最高达到77.76%。根据这些分析结果,可以得出初步结论:十堰3号可以用于核桃油的加工;十堰7号可以用于核仁加工;十堰10号可以用于干果生产。In order to select the best local walnut varieties in Shiyan,Hubei province andincreasing the incomes of local walnut producers and improving market completion ability,twelve walnut varieties were collected based on the field investigation in Shiyan and their morphological traits and main nutrients were analyzed.These results showed that the single fruit weight of Shiyan No.10 was the greatest(11.82 g),and Shiyan No.7 had the highest kernel ratio of 58.01%,and Shiyan No.5 had the highest level of soluble sugars(4.04%).Shiyan No.3 had the highest content of soluble proteins(97.05 mg/g),and the highest level of total proteins occurred in Shiyan No.13(232.67 g/kg),and Shiyan No.3 had the greatest content of crude lipids(77.76%).It was concluded that the fruits of Shiyan No.3 could be used for walnut oil production,and the fruits of Shiyan No.7 could be used for kernel production,and the fruits of Shiyan No.10 could be sold as nuts.
