The Application of Principal Component Analysis on Mainly Economic Characters and Superior Variety Selection of Camellia oleifera Clone
摘要
Abstract
Using the method of principle component analysis,23 characteristics of Camellia oleifera such as fruit height,fruit diameter,fruit shape index,pericarp thickness,Fresh fruit number per 500 g,Fresh seed number per 500g,weight per fruit,fresh fruit seed yield,dry seeds yield,the dry seed kernel,seeds oil content,fresh fruit oil content,Produce fruit of single plant,Oil production per unit area,Oil production Per plant,palmitic acid,Stearic acid,Oleic acid,linoleic acid,Unsaturated fatty acids from 5 clones were studied.According to more than 85% of the cumulative variance proportion and eigenvalues greater than 1,the results proposed 4 principal components and its function equations which reflected the main economic characters of Camellia oleifera clone.The key principal component values of various varietics were calculated,it will be applied to selecting fine varieties,the results were similar to practical phenotype.That the method of principal component analysis was used for main economic characters of Camellia oleifera clone fruit selection is feasible.It will provide a theoretical basis for selecting fine varicties of Camellia oleifera clone.关键词
