摘要: 对20个马铃薯品种的单株块茎产量、淀粉含量、还原糖含量、可溶性糖含量、维生素C含量、蛋白质含量进行分析,并结合主成分分析、隶属函数法、系统聚类分析对马铃薯块茎的品质进行了综合评价,以期筛选出适宜在榆林市种植的适用于不同加工用途且品质优良的马铃薯品种。结果表明,不同马铃薯品种间各品质指标存在很大差异,单株块茎产量、淀粉含量、还原糖含量、可溶性糖含量、维生素C含量和蛋白质含量的变异系数分别为46.76%、50.07%、50.66%、64.79%、33.72%和68.10%。陇薯11号的单株块茎产量与淀粉含量最高,LZ112的还原糖含量最高,陇薯9号的可溶性糖含量最高,老红皮的维生素C含量和蛋白质含量最高。主成分分析结果表明,供试20个马铃薯品种的品质指标可以用4个主成分来表示(方差累积贡献率达90.448%),各成分代表性指标分别为蛋白质含量、淀粉含量、可溶性糖含量、还原糖含量。进一步采用隶属函数法和系统聚类分析对马铃薯品质进行综合评价,共筛选出7个品质较优的马铃薯品种,占供试品种的35.0%。其中,1种(定薯3号)可作为菜用和淀粉加工的兼用种质,1种(甘引薯1号)可作为全粉加工和油炸食品加工的兼用种质,1种(陇薯11号)可作为大规模推广种植后用于淀粉加工的种质,2种(L08104-12和费乌瑞它)可作为全粉加工的种质,2种(冀张薯12号和陇薯9号)可作为油炸类食品加工的种质。

Abstract: The tuber yield per plant,starch content,reducing sugar content,soluble sugar content,vitamin C content and protein content of 20 potato varieties were analyzed,and the comprehensive evaluation of quality was done by principal component analysis,membership function method and cluster analysis,so as to screen out potato varieties with good quality and suitable for different processing purposes and cultivation in Yulin City. The results showed that there were great differences in quality indexes among different potato varieties.The variation coefficients of tuber yield per plant,starch content,reducing sugar content,soluble sugar content,vitamin C content and protein content were 46.76%,50.07%,50.66%,64.79%,33.72% and 68.10% respectively.The tuber yield per plant and starch content of Longshu 11 were the highest,the reducing sugar content of LZ112 was the highest,the soluble sugar content of Longshu 9 was the highest,the vitamin C content and protein content of Laohongpi were the highest.The results of principal component analysis showed that the quality indexes of 20 potato varieties could be expressed by four principal components(the cumulative variance contribution rate was 90.448%),and the representative indexes of each component were protein content,starch content,soluble sugar content and reducing sugar content respectively. Then,comprehensive evaluation was carried out by membership function method and cluster analysis.The results showed that seven varieties with better quality were screened out,accounted for 35.0% of the tested varieties,one variety(Dingshu 3)could be used for both vegetable and starch processing,one variety(Ganyinshu 1)could be used for whole flour processing and fried food processing,one variety(Longshu 11)could be used for starch processing after large⁃scale cultivation,two varieties(L08104⁃12 and Feurita)could be processed as whole flour,and two varieties(Jizhangshu 12 and Longshu 9)could be used for fried food processing.
