| 摘 要： | 用随机区组试验方法，比较四种不同的选育群体团头鲂的后代和一个对照群体团头鲂的生长性能。结果表明：在同一环境条件下，远交群体比近交群体生长优势明显（|xi-xj|＞D0.01）；亲本年龄大（3足龄）的群体后代生长性能优于亲本年龄小（2足龄）的群体后代（|xi-xj|＞D0.05）；对照群体团头鲂与近交群体后代生长性能相当。

| Abstract: | Using a random block design, the growth performance experiment upon Megalobrareaamblycephala has been made by comparing its four different posterifies of selected populationsand one control population. It has proved that, in the same condition, outbreeding populationgrows faster than inbreeding population (| xi- xj | > D0.05). The posterifies from the olderparental populations (three-thoothed ) grow faster than those from the younger (| xi- xj | >D0.05) ; The growth performance of inbreeding population is similar to those of control population. |
