中文摘要：

为了筛选出具有开发潜力的品种，以新疆地区扁桃坚果为研究对象，按照国家标准方法测定38个扁桃品种的壳厚度、出仁率、种仁质量、粗脂肪含量、粗蛋白含量和苦杏仁苷含量，利用隶属函数法综合评价新疆地区扁桃的坚果品质。结果表明：‘克西’的平均种仁质量最大，为1.40 g；‘Nonpareil’的出仁率最高，为72.23%；‘苦巴旦’的壳厚度最小，仅为0.40 mm；‘阿曼尼沙’的粗脂肪含量最高，为60.95%；‘Mission’的粗蛋白含量最高，为30.09%；‘甜仁桃巴旦’苦杏仁苷含量最低，‘小桃巴旦’含量最高。经隶属函数法综合评价，认为扁桃品种‘纸皮’、‘Butte’、‘Thompson’、‘Sonora’、‘Nonpareil’、‘叶尔羌’、‘巴旦王’的综合品质最优，具有较大的开发潜力。

英文摘要：

In order to select out almond cultivars with development potential, the nuts of 38 varieties of almond in Xinjiang area were chosen as research objects to determine the shell thickness, kernel percentage, kernel mass, crude fat content, crude protein content and amygdalin content according to the national standard method, and to comprehensively evaluate the nuts quality of almond in Xinjiang by using the subordinate function method. The results showed： the average kernel mass of ‘Kexi’ was the highest, reaching 1.40 g; ‘Nonpareil’ had the greatest kernel percentage （72.23%）; the shell thickness of ‘Kubadan’ was the smallest, only 0.40 mm; ‘Amannisha’ had the highest content of crude fat （60.95%）; the crude protein content in ‘Mission’ was the lowest （30.09%）; ‘Tianrentaobadan’ had the lowest content of amygdalin, while ‘Xiaotaobadan’ had the highest content. Based on the results of comprehensive evaluation with the method of subordinate function, the comprehensive qualities of ‘Zhipi’, ‘Butte’, ‘Thompson’, ‘Sonora’, ‘Nonpareil’, ‘Ye’erqiang’ and ‘Badanwang’ were thought to be the highest and these almond cultivars had the greater development potential.
