Phenology, productivity, fruit size, outer fruit, inner fruit, and vigor traits in an apple reference population

This dataset contains the phenotypic data of the apple REFPOP multisite trial. The apple REFPOP (reference population) is made of 534 genotypes, split into two groups: an accession group, involving 269 accessions of European and non-European origin representing the diversity in cultivated apple, and a progeny group, comprising 265 genotypes, which stemmed from 27 parental combinations. The population was planted in six locations in 2016, with two or four trees of each genotype/accession per location. The six locations were (i) Rillaar, Belgium, (ii) Angers, France, (iii) Laimburg, Italy, (iv) Skierniewice, Poland, (v) Lleida, Spain and (vi) Wädenswil, Switzerland. Thirty traits related to phenology, productivity, fruit size, outer fruit, inner fruit, and vigor were evaluated at up to six locations, during up to three seasons (2018-2020). Trunk diameter was measured in 2017 in some locations, enabling for a trunk increment calculation for 2018. Data for all traits were used in the paper by Jung et al. (2022) "Genetic architecture and genomic predictive ability of apple quantitative traits across environments" and are published in version 2 of the dataset. Data for harvest date, fruit overcolor, fruit weight and fruit number, were used in the paper by Cazenave et al. (2021) "Combining genetic resources and elite material populations to improve the accuracy of genomic prediction in apple" (see Metadata for complete reference) and were made available in the first version of the dataset.

本数据集收录苹果REFPOP（reference population，参考群体）多地点试验的表型数据。该苹果参考群体由534份基因型材料组成，分为两个类群：一类为种质资源群，包含269份源自欧洲及非欧洲地区的种质材料，涵盖栽培苹果的遗传多样性；另一类为杂交后代群，包含265份基因型材料，均源自27个亲本组合。该群体于2016年在6个试验地点定植，每个基因型/种质材料在各地点均定植2株或4株。6个试验地点分别为：(i) 比利时Rillaar（里拉尔）、(ii) 法国Angers（昂热）、(iii) 意大利Laimburg（莱姆堡）、(iv) 波兰Skierniewice（斯凯尔涅维采）、(v) 西班牙Lleida（莱里达）以及(vi) 瑞士Wädenswil（瓦登斯维尔）。研究人员在最多6个地点、最多3个生长季（2018-2020年）内，对与物候期、生产性能、果实大小、果实外观、果实内质及树势相关的共30项性状开展了评价。2017年部分试验地点测定了树干直径，据此可计算2018年的树干生长增量。所有性状的测定数据均已应用于Jung等人2022年发表的题为"Genetic architecture and genomic predictive ability of apple quantitative traits across environments"（跨环境下苹果数量性状的遗传结构与基因组预测能力）的研究论文，并以数据集版本2的形式公开发布。其中收获期、果面色（fruit overcolor）、单果重（fruit weight）及坐果数（fruit number）的相关数据已应用于Cazenave等人2021年发表的题为"Combining genetic resources and elite material populations to improve the accuracy of genomic prediction in apple"（结合遗传资源与优良种质群体提升苹果基因组预测精度）的研究论文，并以数据集第一版的形式公开，完整参考文献详见元数据。
