Correlation and path analysis of fruit, leaf and flower traits in Chinese jujube hybrid progeny

To discuss the correlation and path analysis on traits of fruits, leafs and flowers in Chinese Jujube hybrid progeny, and 9 related traits of 140 hybrid progeny from 'JMS2' x 'Jiaocheng 5' were investigated and analyzed. The results showed that the leaf length, leaf width, leaf area, flower area, fruit longitudinal diameter and fruit transverse diameter had highly significant positive correlation with single fruit weight, and the flower diameter, flower disk diameter had significant positive correlation with single fruit weight. The leaf length, fruit longitudinal diameter and fruit transverse diameter were the main factors affecting fruit weight, the direct path coefficient were 0.0627, 0.3837 and 0.6415, respectively.
