基于主成分分析和隶属函数法对不同马铃薯种质资源农艺性状的综合评价
Comprehensive evaluation of agronomic traits in different potato germ-plasm resources based on principal component analysis and membership function method
摘要
Abstract
In order to screen out superior potato varieties(lines)suitable for cultivation in Hulunbuir,17 potato varieties(lines)were used as the test materials.By observing and recording major main agronomic traits,a comprehensive evalua-tion was conducted using coefficient of variation analysis,principal component analysis,cluster analysis and membership function analysis.The results showed that the coefficient of variation among the 17 potato varieties(lines)ranged from 9.44％to 26.78％,with the single plant yield exhibiting the greatst variation.The correlation analysis results showed that the number of tubers per plant was significantly positively correlated with the yield per plant.The principal component analysis results showed that the contribution rate of component 1,component 2 and component 3 were 33.939％,28.742％and 16.939％,respectively.The cluster analysis showed that when the euclidean distance was 10,the 17 potato varieties(lines)could be divided into seven groups.The membership function analysis results showed that the comprehensive rank-ings of V7,Huasong 7,BL-17 and DW2 were relatively high.In conclusion,V7,Huasong 7,BL-17 and DW2 possess ex-cellent germplasm resources and breeding potential for he Hulunbuir region.关键词
