Data from: Artificial selection on anther exsertion in wild radish, Raphanus raphanistrum

To study the genetic architecture of anther exsertion, a trait under stabilizing selection in wild radish, artificial selection on anther exsertion was applied for 11 generations. Two replicate lines each of increased and decreased exsertion plus two randomly-mated controls were included. Full pedigree information is available from generation five. To estimate correlated responses to selection, 571 plants from all lines and matrilines were grown in the greenhouse and a number of floral, growth, and phenology traits were measured. To create an outbred F2 mapping population, all possible crosses among the two high and two low exsertion lines were made, using a multiple-family design to capture the genetic variance still present after 11 generations of selection. Six floral traits were measured on 40 parents, 240 F1, and 4,868 F2 offspring. Opportunities for reuse of these data include traits not previously analyzed, other analyses, especially using the pedigree and fitness data, and seeds from all generations and photos of flowers in the later generations are available.为研究野生萝卜（wild radish）中受稳定选择（stabilizing selection）作用的性状——花药伸出量（anther exsertion）的遗传结构（genetic architecture），本研究对花药伸出量开展了11代的人工选择（artificial selection）。本研究设置了两个花药伸出量增加的重复选育系、两个花药伸出量减少的重复选育系，以及两个随机交配的对照组；自第5代起，所有材料均拥有完整的系谱（pedigree）信息。为评估选择的相关响应，研究人员将所有选育系和母系家系（matrilines）的共571株植株种植于温室，并测定了一系列花部、生长及物候相关性状。为构建远交F2作图群体（outbred F2 mapping population），研究人员采用多家系设计（multiple-family design），对两个高伸出量和两个低伸出量的选育系开展所有可能的杂交组合，以捕捉11代选择后仍留存的遗传变异（genetic variance）。研究人员对40个亲本、240株F1代个体及4868株F2代子代共测定了6种花部性状。该数据集具备多项复用潜力：可用于此前未被分析的性状研究、其他各类分析（尤其是基于系谱和适合度（fitness）数据的分析）；此外可获取所有世代的种子以及后续世代的花朵照片。
