| 摘 要： | 在福建省洋口国有林场对23年生杉木种源间和种源内两水平双列交配设计的90个杂交组合子代测定林的树高、胸径、材积3个生长性状的配合力进行分析。结果表明:江西×湖南和湖南×福建种源组合在23年生时3个生长性状中的总配合力表现均排在前3位;江西×福建种源组合在23年生时胸径性状的总配合力表现最优;江西(全南12)×湖南(靖县21)家系组合在23年生时3个生长量性状中的总配合力表现均排在第1位。

| Abstract: | In this paper,the combining ability of height,dbh,and volume of 90 cross combination progeny test forest were studied based on a two-level diallel cross experiment of 23-year-old Cunninghamia lanceolata(lamb.)Hook sp in Yangkou Forest Farm.The main results were as follows: The total combining ability of 2×3 and 3×4 provenance crosses were ranked at the first three in the 23th year genetic testing on the three growth traits;2×4 provenance cross was the best in the 23th years genetic testing in DBH;2(4)×3(8) individual cross was the best in the 23th year genetic testing on the three growth traits. |
