| 摘 要： | 贵州省内选择出的19株优树子代进行了苗期测定,结果表明:各家系间在苗高、地径上均存在极显著差异,遗传变异系数分别为8.1%和18.6%,这些变异受强遗传控制,苗高与地径呈极显著相关,相关系数达0.639,地径指标对南酸枣进行优良家系选择中有着重要地位,通过苗期试验结果分析,选出优良家系4个。

| Abstract: | The seedlings of 19 elite trees of Choerospondias axillaris were tested for their character variation.The results of the study showed that there were significant differences among the different families in seedling height and ground diameter,of which the genetic variation coefficients were 8.1% and 18.6% respectively,The variation was under strong genetic control,and the ground diameter had a higher heritability than that of height.The height and the ground diameter had a significant correlation,with a coefficient of 0.639.The ground diameter was of great importance for the selection of excellent families,and,as a result of the study,4 excellent families were screened out e,all of which have above-average ground diameters. |
