Abstract:
【Objective】 This study analyzed the economic characters and fruit nutrition component, in the hope of providing the oretical basis for the selection and comprehensive development and utilization of excellent
Armeniaca vulgaris var.
ansu families.
【Methods】 Taking 38
Armeniaca vulgaris var.
ansu families from Ningxia and Gansu Provinces as the material, their economic characters and fruit nutrition components were studied by means of variation analysis,multiple comparison,correlation analysis and principal component analysis.
【Results】 The variation coefficient of fruit yield was 0.78, the Shannon index of VC content was 2.02, and the Shannon index of fruit nutrition components was higher than that of economic characters. The variation degree of economic characters and nutrition component of
Armeniaca vulgaris var
.ansu families was high, and the diversity was rich. There was a strong correlation between the content of nutrition components and fruit traits, among which single fruit mass was positively correlated with the three diameters of fruit. The cumulative contribution rate of principal component analysis was 78.786%, which could represent the main information of characters.
【Conclusion】 Six excellent families, such as No.102, No.119 and No.201, are selected synthetically, among which, No.102 and No.119 families have good taste of fresh fruit, high nutritional value, and No.201 family has the largest fruit yield, which can be used as the type of high yield.
