The present study was carried out in a progeny trial established by ten population of Anatolian black pine [Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe.] to estimate genetic variation, heritability, genetic gain and also genetic and phenotypic correlations among the characters based on 9th year results of tree height and branch characters in the trial. Average tree height was 112.7 cm in polled population, while average of branch characters were generally similar. The results of ANOVA showed statistically significant difference (0.05>p) among the population for characters. Family x population interaction was also found statistically significant. Variation among family was lower than that of within families for the characters. Family mean heritability (0.65 < h(f)²) was higher than individual heritability (0.42 < h(i)²) for the characters. Genetic variation among population showed low ratio in total variation, while it was very high among and within the families. It emphasized importance of individual selection in breeding programme. Phenotypic correlation was statistically significant between tree height and branch diameter only. It was also highest in genotypic correlation (r = 0.81).
本研究在由10个安纳托利亚黑松种群[欧洲黑松阿诺德亚种帕拉斯松（拉姆）霍尔姆博伊]建立的子代试验中进行，以根据试验中树高和分枝性状的第9年结果估计遗传变异、遗传力、遗传增益以及性状之间的遗传和表型相关性。授粉种群的平均树高为112.7厘米，而分枝性状的平均值总体相似。方差分析结果表明，各性状在种群间存在统计学显著差异（0.05>p）。还发现家系×种群互作具有统计学显著性。各性状在家系间的变异低于家系内的变异。各性状的家系均值遗传力（0.65 < h(f)²）高于个体遗传力（0.42 < h(i)²）。种群间的遗传变异在总变异中所占比例较低，而在家族间和家族内则非常高。这强调了个体选择在育种计划中的重要性。仅树高与分枝直径之间的表型相关性具有统计学显著性。其基因型相关性也最高（r = 0.81）。
