| 摘 要： | 在初级种子园研究的基础上,确立了油松高世代种子园建园材料的选择标准,通过对142个油松优树进行半同胞子代测定,选出36个优良家系,树高、胸径、材积平均增产15.4、26.9、73.3,遗传增益分别为8.2、8.5、22.2.再从优良家系内选择263个优良单株,树高、胸径、材积平均增产27.2、41.1、125.9,预期遗传增益分别为13.3、11.7、37.2.并提出了高世代种子园建立技术和种子高产技术.

| Abstract: | Based on establishment of primary orchard of Chinese pine(Pinus tabulaeformis), material-selecting criterion of the second generation orchards was determined. 36 excellent families were selected by means of half-sib progeny test on 142 families belonging to 3 groups of materials. Furthermore, 263 plus tree were selected from 36 families, and their average height, dbh and tmber volume increased by 27.2%, 41.1% and 125.9% respectively, their expecting genetic gains in the average height, dbh and timber volume were 13.3%, 11.7% and 37.2% respectively. The establishing techniques of the second generation clone-orchards are proposed. |
