Variation of seed characters in Korean pine (Pinus koraiensis ) multi-clonal populations

  • 摘要: 选取红松4个种子园共60个无性系,对红松种实性状进行变异分析、相关分析,揭示红松种实性状在无性系来源群体间和无性系间的变异特征及规律。结果显示,红松种实性状存在丰富的变异,遗传多样性水平较高,居群间平均表型分化系数为29.82%,小于居群内变异(70.18%),居群内变异是红松种实性状的主要来源。除种长、种宽、长宽比外其余性状在居群间差异显著(P0.05),红松种实各性状在种子园内无性系间差异均极显著(P0.01)。广义遗传率为61.54%~94.81%,受遗传控制程度较强,通过优良无性系选择,能获得较高的遗传增益(4.70%~74.52%)。相关分析结果表明,在不同的立地条件下,千粒质量与种仁质量、种皮质量,出仁率与种仁质量/种皮质量、粗纤维含量、碳水化合物含量,种仁质量与种长、种宽、种皮质量,碳水化合物含量与油脂含量、蛋白质含量及多糖含量,油脂含量与出仁率、种仁质量/种皮质量、蛋白质含量、多糖含量,长宽比与油脂含量、蛋白质含量、多糖含量的相关关系非常稳定。通径分析与多元逐步回归分析均表明,长宽比和碳水化合物含量均为4个种子园中影响油脂含量的主要因素,其中,长宽比的直接作用最大。因此,根据红松种实性状对种子园无性系再选择,提高营养成分指标,提高种质资源品质,具有实际的应用价值。
