摘　　要：本文阐述建立文冠果优良基因收集圃过程和步骤,并对圃内三类群体26个家系(混系)2 a生生长量进行评价,结果表明:造林后,优树群体无论是当年成活率还是第2 a保存率都明显优于高海拔群体和普通群体。在树高生长量方面,优树群体超过普通群体98.3%、超过高海拔群体39.4%;在地径生长量方面,优树群体超过普通群体35.6%、超过高海拔群体17.0%。三类群体在树高和地径生长量上优劣顺序为优树群体>高海拔群体>普通群体。在树高和地径生长量上表现最好3个家系为Y6、Y4和Y5。The course and procedure of excellent genetic collection field construction of Xanthoceras sorbifolia was expoun- ded in this paper. Furthermore, three types of groups 26 families （composite variety） 2 a increment was evaluated. The re- sult showed thaf the survival rate of first year and preserving rate of the second year of select tree were superior than the high altitude group and general group after afforestation. The select tree surpassed 98.3% and 39.4% compared with general group and high altitude group from the aspect of height of tree increment. In addition, the select tree surpassed 35.6% and 17.0% compared with general group and high altitude group from the aspect of ground diameter increment. The sequence of three groups with height of tree and ground diameter increment was select tree 〉 high altitude group 〉 general group. The best 3 families presented in height of tree and ground diameter increment were Y6 ,Y4 and Y5.
