以引种至宁夏的18个鲜食葡萄为试材,对鲜食葡萄品种的14个果实经济学指标进行观察测定,并运用层次-关联度和系统聚类分析评价了宁夏银川地区引种的18个有核鲜食葡萄的综合品质,以期筛选出适应当地且品质优良的鲜食葡萄品种,为宁夏地区鲜食葡萄发展提供可开发资源的科学依据。结果表明:内在品质权重值高于外在品质,其中内在品质中的香味、风味权重赋值最高,其次是判别风味口感的主因子固酸比和糖酸比,而单果质量和单穗质量是影响外在品质的重要因素;根据供试品种与参考品种的加权关联度将18个有核鲜食葡萄品种综合品质排序,并利用系统聚类对其进行分类,‘早黑宝’综合品质最好,其次是‘金手指’,再次是‘阳光玫瑰’,18个有核鲜食葡萄品种共聚为6类。‘早黑宝’和‘阳光玫瑰’的外观品质和内在品质均表现优良,且口感好、香味浓郁、风味佳,‘金手指’‘瑞都香玉’‘香妃’‘贵妃玫瑰’4个品种内在品质表现优良,外在品质表现良好,且口感独特、特点突出、香味和风味俱佳。
Using 18 fresh grape introduced to Ningxia as test material, 14 fruit economic indexes of fresh grape varieties were observed and measured. By using the hierarchy-association degree and cluster analysis, 18 introduced grape varieties in Yinchuan, Ningxia were evaluated. A comprehensive quality of nuclear edible grapes, with a view to filter out the local varieties of fresh and good quality grapes for the development of fresh grape in Ningxia to provide a scientific basis for the development of resources. The results showed that the intrinsic weight value was higher than the external quality, of which the intrinsic quality of the flavor, the highest value of flavor weight assignment, followed by the determination of flavor and taste of the main factors of solid acid ratio and sugar acid ratio, and fruit quality and single ear quality is affected According to the weighted correlation degree between the tested varieties and the reference varieties, the comprehensive quality of 18 edible fresh grape varieties was sorted and classified by systematic clustering. The comprehensive quality of ’Early Dark Po’ was the best , Followed by the ’Golden Finger’, again the ’Sunshine Rose’, and 18 edible grapes were grouped into 6 categories. ’Early Black’ and ’Sunshine Rose’ have excellent appearance quality and inner quality, with good taste, rich aroma and good flavor, ’Golden Finger’, ’Shui Hong Xiang’, ’Xiang Fei,’ ’Royal Rose’ 4 Intrinsic quality of varieties performed well, the external quality of good performance, and taste unique, prominent features, fragrance and flavor are superb.
