摘　　要：对16年生马尾松生长性状研究表明:不同种源马尾松林分子代生长量差异均极显著。马尾松优良林分4年生与16年生生长情况有较大变化。通过对各参试林分的多重比较,根据材积的遗传增益排名,选出了DLSD检验显著的7个优良林分作为林分—单株二层次选择的育种材料。对参试林分的单株生长情况进行了遗传参数分析,根据材积增益排名选出排在前100位的单株进入基因库作为第2代育种材料。Based on the study on the growth characters of 16-year-old stands of Pinus massoniana, the results show that there are significant differences among progeny growth from the stands of different provenances. It is a great change in the yield between the 4-year-old and 16-year-old stands. Through the multi-comparison, 7 superior stands with DLSD significant difference have been selected as the second generation breeding materials under the sequence of the volume growth. Based on analyzing and comparing the genetic parameters among the individuals of the tested stands, 100 individuals have been selected as the second generation breeding material in gene pool under the sequence of the volume growth.
