甘肃省旱作区马铃薯品种(系)品质分析与评价
Quality analysis and evaluation of potato varieties(lines)in dry farming areas of Gansu province
摘要
Abstract
In order to screen out high-quality potato varieties(lines)suitable for planting in dry farming areas of Gansu province,19 indicators related to the tuber traits,basic nutritional indexes,and mineral element contents of 37 potato vari-eties(lines)were measured,and comprehensive evaluations of potato quality were conducted using correlation analysis,principal component analysis,and hierarchical cluster analysis.The results showed that the coefficient of variation of sele-nium content,average single tuber mass,and magnesium content were higher,reaching 0.64,0.47,and 0.45,respectively.Correlation analysis indicated that there were significant correlations among the 19 indicators of the 37 potato varieties(lines).By using principal component analysis,the quality of 37 potato varieties(lines)was comprehensively evaluated,with LY1631-1 and Linshu No.18 ranking first and second,and their comprehensive scores being greater than 1.A model was constructed using stepwise linear regression,and the verification results showed that the principal component analy-sis model was accurate and reliable.Hierarchical cluster analysis showed that the materials could be divided into three ma-jor categories at a threshold of about 1.5,with the first category(LY1631-1,Linshu No.18,etc.,26 materials)having a high comprehensive evaluation,the second category(Lishu No.6,etc.,9 materials)having a moderate comprehensive evaluation,and the third category(L1 330-33,LY1520-9)having a low evaluation.In conclusion,26 varieties(lines)with high comprehensive evaluation such as LY1631-1 and Linshu No.18 can be used as high-quality potato germplasm re-sources in dry farming areas of Gansu province.关键词
