Factor Analysis on Fruit Quantitative Characters of Macadamia spp
摘要
Abstract
Eleven fruit quantitative characters of 28 Macadamia germplasm resources were classified into two principal factors with low correlation through the method of factor analysis. The accumulated variance contribution rate of the 2 major factors reached 80.353% and fairly reflected the information included in these characters. According to the characters included in the main factors and their reflected meanings in biology, these 2 main factors could be successively named as the factor of fruit weight F1 and the quality factor of unshelled nut F2 based on the variance contribution. The orthogonal and oblique factor load matrices were analyzed for the correlationship of characters, and the comprehensive factor scores of 28 Macadamia germplasm resources could be used in the evaluation on germplasms.关键词
