摘要 为开展鲜食型和加工型马铃薯品种的综合评价与科学分类,本研究针对10个四川省川中丘陵区冬作马铃薯的主栽品种开展了外观指标(单薯重、薯块形状、表皮颜色、芽眼深浅和个数、果肉色差、果肉硬度)和营养指标(干物质率、淀粉含量、可溶性糖含量、可溶性蛋白含量、VC和总酚含量)的测定分析与综合品质评价。应用SPSS软件对基础数据进行差异显著性和相关性分析表明,各品种间测定指标均呈现不同程度的差异,薯块果肉硬度和干物质率呈显著正相关(P<0.05);应用主成分分析对10项测定指标进行降维处理,评价得出10个品种的综合得分排名,其中川芋10号、川芋50和青薯9号综合排名前3;应用Ward聚类方法对供试品种的主要营养指标进行了系统聚类分析,将10个品种划分为4个类别,结合基础数据和主成分分析结果讨论了各类别马铃薯品种的品质特征。 In order to comprehensive evaluation and scientific classification of fresh and processed potato varieties,the appearance indexes(single potato weight,tuber shape,peel color,bud eye depth and number,pulp color and hardness)and nutrition indexes(dry matter,starch,soluble sugar,soluble protein,VC and total phenol content)of 10 winter potato cultivars in hilly areas of central Sichuan province were determined and analyzed.SPSS software was used to analyze the significant difference and correlation between the basic data.The results showed that there were various degrees of differences among the tested indexes of different varieties,and there was a significant positive correlation between the pulp hardness and dry matter of potato tubers(P<0.05).Principal component analysis was used to reduce the dimension of 10 indexes,and the comprehensive scores of 10 varieties were ranked.Among them,Chuanyu No.10,Chuanyu No.50 and Qingshu No.9 ranked the top 3.The main nutritional indices of the tested varieties were systematically clustered by Ward clustering method.Ten varieties were divided into four categories.The quality characteristics of different types of potato varieties were discussed based on basic data and principal component analysis results.
