兔眼蓝莓品种主要农艺性状的相关分析

明确蓝莓各农艺性状对目标性状影响的主次关系,可为蓝莓引种栽培和育种提供科学依据.用多重比较、相关分析和灰色关联分析法对蓝莓8个农艺性状之间的相互关系进行了分析.结果表明,与株产关联度最大的为结果枝数,其次为每枝结果数和单果重;单株产量与株高、结果枝数、平均每枝结果数、单株一年生枝树和单果重达到了极显著正相关,与果蝇发生率为负相关.

Correlation and grey relational analysis of main agronomic traits of rabbiteye blueberry

A better understanding of the primary and secondary correlation among various agronomic traits and the objective of rabbiteye blueberry is helpful for blueberry breeding, introduction and cultivation. The relationship among 8 agronomic traits of blueberry was analyzed by using the multiple comparison, correlation analysis and grey relation analysis. The result showed that the plant yield had the greatest correlative degree with the number of bearing branches, and had less correlative degree with the weight of single fruit and fruit number of each branch. The single plant yield had significantly positive correlation with plant height, number of bearing branches, average fruit number of each branch, number of branches born in a year, and single fruit weight, while the single plant yield had negative correlation with the occurrence rate of fruit fly.
