摘　　要：利用１９７６年开始的全国马尾松种源试验１３省（区）６批种源试验林（含局部、全分布区种源试验及中试）材料，对幼林高径、材积生长，干形，结实，抗性，保存率等作性状间遗传、表型相关和年度间相关分析，结果表明对马尾松种源作早期选择是可行的。据两次全分布区试验多点材积资料分析，种源与造林区、种源与试验点间均存在明显的交互作用，种源材积在地点间相关密切；用Ｗｒｉｇｈｔ模型衡量两次试验各参试种源稳定性并划分类型；据保存率和抗寒性分析种源适应性差异。运用指数法为不同造林区和立地类型综合评选优良种源，发现我国马尾松优良种源区集中于南岭山地、云开大山及大娄山、武夷山地。不同造林区种源选择效果明显，材积增益平均达４６．２％，其中尤以北带和中带东、中区高达６０％～１１０％。Analysis study on genotype and phenotype correlation of tree height,DBH,volume growth,stem form,bearing,resistance and survival rate of six groups of the nationalmasson pine provenance trial stands was conducted in 13 provinces since 1976,and the resultssuggested that fine provenances could be selected on these traits. The volume data from twoali-distribution trails in three afforestation regions` nine sites indicated that there were evi-dent interaction between provenances and afforestation regions or site types within afforesta-tion regions,and significant provenances` correlation among sites. Provenances` stability andadaptability were studied with Wright` s model and divided into different types. Provenances`survival rate and hard-resistance were studied and their correlations with latitude wereanalysed.In the integrated provenance selection by index for above-mentioned traits for theafforestation regions and site types,Nanling,Yunkaidashan,Daloushan and Wuyishan moun-tain areas were found as our country` s main fine provenance regions. The provenance selec-tion effects for different afforestation regions were very significant,while volume gains aver-aged 46.2%(the heighest 60%～110%)in both northern zone and eastern and central re-gions of central zone.
