摘　　要：　通过"基因型×密度"的互作试验,证实了基因型与密度存在着明显的互作效应,且不同家系与密度的互作方式不一.评选出纸浆材密生型家系33个,其遗传增益达21.21%～161.21%,以此奠定了马尾松造纸材密生型家系选择的理论依据.An experiment on the interaction of the genotype×density for Mass pine proves that there is a significant interaction between them and there are different modes of interaction among different families. According to the results, 33 pulp-oriented compact families have been selected, whose genetic gain is 21.21% to 161.21%, and a theoretical basis for this selection has been provided.
