马尾松种源有限区（中间）试验早期结果表明，种源间在生长上存在极显著的差异．通过多重比较，初步筛选出广西恭城和宁明两个种源，树高生长比当地马尾松快２６％，冠幅较窄；每年生轮盘数较多．本文还报道了马尾松种源早期树高、地径、冠幅、轮盘数和枝角等性状的相关性及遗传方差、环境方差、种源遗传力、单株遗传力、选择响应和遗传变异系数等遗传参数．
The early results of the Pinus massoniana provenance limited area (middle) trial showed that there was a very significant difference in growth between provenances. Through multiple comparisons, the two provenances of Gongcheng and Ningming in Guangxi were initially screened, and the tree height growth was 26% faster than that of native Masson pine, the crown width was narrower; The paper also reported the correlation between genetic diversity, environmental variance, provenance, individual heritability, selective response and genetic variation in the early provenance of Pinus massoniana provenances, such as height, diameter, crown width, Coefficients and other genetic parameters.
