Determination of Macadamia ternifolia Fruit Inclusions and Diversity Analysis in Yunnan Province
摘要
Abstract
In order to explore the diversity of Macadamia ternifolia fruit inclusions,71 Macadamia ternifolia specific germplasms were used as materials.Genetic variation analysis,correlation analysis,principal component analysis and cluster analysis were performed for 8 inclusions from the germ-plasm.The results showed that the fruit inclusions of Macadamia ternifolia germplasms had abun-dant variation,and the variation coefficients of fructose,glucose and sucrose were higher,which were 53.25％,37.39％and 35.47％,respectively.There was significant negative correlation between sucrose and glucose,crude fat and fructose,but no significant correlation between other inclusions.Principal component analysis extracted the first 4 principal components,and the maximum cumulative contribution rate was 64.591％.The fruit contents of 71 Macadamia ternifolia germplasms were divided into seven categories by cluster analysis.Deeply analysis on difference and diversity between Macadamia ternifolia germplasm inclusions was conducted,which provided basic data support for Macadam-ia ternifolia breeding to promoting the sustainable development and improvement of its industry.关键词
