Multisite common garden experiments, exposing common pools of genetic diversity to a range of environments, allow quantification of plastic and genetic components of trait variation. For tree species, such studies must be long term as they typically only express mature traits after many years. As well as evaluating standing genetic diversity, these experiments provide an ongoing test of genetic variation against changing environmental conditions and form a vital resource for understanding how species respond to abiotic and biotic variation. Finally, quantitative assessments of phenotypic variation are essential to pair with rapidly accumulating genomic data to advance understanding of the genetic basis of trait variation, and its interaction with climatic change. We describe a multisite, population-progeny, common garden experiment of the economically and ecologically important tree species, Scots pine, collected from across its native range in Scotland and grown in three contrasting environments. Phenotypic traits, including height, stem diameter and budburst were measured over 14 growing seasons from nursery to field site. The datasets presented have a wide range of applications.
多地点共同花园实验将共同的遗传多样性暴露在一系列环境中，从而可以量化性状变异的可塑性和遗传成分。对于树种来说，由于它们通常需要多年才能表现出成熟的特征，因此这些研究必须是长期的。除了评估现有遗传多样性外，这些实验还针对不断变化的环境条件对遗传变异进行了持续测试，并为了解物种如何应对非生物和生物变异提供了重要资源。最后，对表型变异进行定量评估对于与快速积累的基因组数据相结合以推进对性状变异的遗传基础及其与气候变化的相互作用的理解至关重要。我们描述了一个多地点、种群-后代的共同花园实验，该实验针对的是经济和生态上重要的树种——苏格兰松，它从苏格兰的整个原生范围中采集，并在三个截然不同的环境中生长。在从苗圃到田间的 14 个生长季节中，测量了包括树高、茎直径和芽膨出在内的表型性状。所提供的数据集具有广泛的应用。
