Analysis and Comprehensive Evaluation of Fruit Quality of Superior Individuals of Elaeagnus mollis Diels
摘要
Abstract
[Objective]This study conducted a difference analysis on the fruit phenotypic traits and quality of 30 superior individuals of Elaeagnus mollis Diels,and performed a comprehensive evaluation using statistical methods such as correlation analysis and principal component analysis,aiming to initially construct a comprehensive evaluation system for Elaeagnus mol-lis Diels and provide theoretical support for variety breeding and genetic improvement of Elaeagnus mollis Diels in Shanxi Province.[Methods]Thirty initially selected superior individuals of Elaeagnus mollis Diels from Xiangning and Yicheng counties in Shanxi Province were used as test materials.Twelve morphological and quality traits including fruit longitudinal di-ameter,transverse diameter,and single fruit weight were determined.Coefficient of variation analysis,pearson correlation a-nalysis,and principal component analysis(PCA)were employed to investigate the variation patterns of fruit traits,correlation characteristics among traits,and comprehensive evaluation system of the superior individuals of Elaeagnus mollis Diels.[Results]The coefficients of variation(CV)of the 12 fruit traits of the 30 superior individuals ranged from 2.27%to 58.13%.Among these traits,single stone weight(CV=58.13%)and single fruit weight(CV=55.61%)showed the most significant variation,while linoleic acid(CV=2.27%)and oleic acid(CV=4.54%)exhibited the highest stability.Extremely significant positive correlations were detected among fruit morphological traits,whereas the kernel rate was extremely signifi-cantly and negatively correlated with fruit size and weight.Three principal components(PCs)with eigenvalues≥1 were ex-tracted via PCA,accounting for a cumulative contribution rate of 71.867%.The constructed comprehensive evaluation model identified six optimal individuals,namely No.10,No.9,No.8,No.12 and No.11.[Conclusion]The results clarify the variation patterns of fruit traits and core selection indices of Elaeagnus mollis Diels,which provides theoretical and methodo-logical support for subsequent elite variety breeding and genetic improvement.关键词
