| 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. |
