Correlation Analysis on Morphological Traits of Ziziphus jujuba‘Huizao’Fruit

On November 2021, fruits of Ziziphus jujuba‘Huizao’ cultivated were collected in orchards at 8 villages of Wenfu county, Xinjiang. Determinations were conducted on vertical and horizontal diameter of fruit and stone, single fruit weight, pulp and stone weight, edible rate. The results showed that the morphological traits of dates had different variation, especially weight of pulp and stone, single fruit had more than 20.00% of coefficient of variation, stone morphological index, stone vertical and horizontal diameter between had10.00%-20.00% , and the other traits had less than 10.00%, with the smallest of fruit edible rate (2.96%). Correlation analysis showed that there was significant correlation among the most of the fruit morphological traits. There was extremely significant positive correlation between vertical and horizontal diameter of fruit, vertical and horizontal diameter of stone, with correlation coefficient of 0.47 and 0.49, as well as between single fruit mass with pulp weight and edible rate (P <
