【目的】研究马尾松全轮伐期半同胞家系的遗传变异并进行选择评价,为马尾松高世代遗传改良提供可靠依据。【方法】对南宁市林业科学研究所26年生马尾松初级种子园169个半同胞家系子代测定林进行长期定位观测,分析了树高、胸径和材积3个性状的方差分析、遗传力分析和家系选择。 【结果】家系间树高、胸径、材积存在极显著差异,表明马尾松初级无性系种子园的半同胞家系间存在丰富的变异,改良潜力较大; 分别有2.96%和5.33%的家系材积生长量低于古蓬种源和武鸣种源,表明建园优树无性系具有较好的基因型; 树高、胸径和材积的家系遗传力分别为0.555、0.466和0.423,属中等至高等遗传力; 3个性状的单株遗传力分别为0.219、0.128和0.111,属低等遗传力; 家系遗传力和单株遗传力均表现为树高>胸径>材积,即树高具有较强遗传力。【结论】以家系材积均值和材积变异系数作为选择指标进行马尾松优良家系选择,其中37、98、107、113和137号5个家系入选,可作为优良家系进行推广应用。
Abstract
【Objective】 To determine genetic variation and selection evaluation of the entire alternation cutting period of masson pine(Pinus massoniana Lamb.)half sibling families could provide a reliable basis for high generation genetic improvement for masson pine. 【Methods】 Long-term tree height, DBH and wood volume were analyzed based on the 169 half compatriot progeny test forest of 26-year-old masson pine seed orchard in the Nanning Forestry Division. 【Results】 Tree height, DBH and wood volume were significantly different among families, which indicated the primary clonal seed orchard of masson pine had rich variation among the half compatriot and great improvement potential. Family wood volume growth was lower than that of the Gupeng provenance by 2.96% and lower than that of the Wuming provenance by 5.33%. This indicated that some trees had better genotypes. The family heritability of tree height, DBH and volume were 0.555, 0.466 and 0.423, respectively, in medium-high heritability. The individual heritability of those three was 0.219, 0.128 and 0.111, in low heritability. Both the family and individual heritabilities represented as tree height > DBH > wood volume and tree height had strong heritability. 【Conclusion】 Based on the selection index of the family mean wood volume and volume variation coefficient, 37, 98, 107, 113 and 137 were selected as superior families; these could be used for the high generation genetic improvement of masson pines.
