Data from: Seed size has a major impact on fall seedling vigor in the cover crop hairy vetch (Vicia villosa Roth)

This data is a subset of the Cover Crop Breeding Network's hairy vetch breeding program containing (1) maternal plants which have a seed size measurement and (2) their offspring. Individuals were grown over multiple years at multiple sites in the eastern continental US. Each row represents a plant and their ID code contains the site (using U.S. state acronym) and year (formatted 20XX). For all individuals, visual fall and spring vigor scores are included, when available. Seed size is presented as two dimensional square millimeters based on a digital measurement from an image. This dataset was used in a publication which concluded that seed size in hairy vetch is closely linked to seedling vigor, as measured by a visual fall vigor score.

本数据集为覆盖作物育种网络（Cover Crop Breeding Network）毛叶苕子（hairy vetch）育种项目的子集，包含两类供试材料：（1）带有种子尺寸测量数据的母本植株，以及（2）其后代植株。所有个体于美国大陆东部的多个试验点、跨越多个年度开展种植。每一行代表一株植株，其ID编码包含试验地点（采用美国州名缩写形式）与栽培年份（格式为20XX）。针对所有供试个体，若有可用记录则包含秋季与春季植株活力的目视评分。种子尺寸以二维平方毫米为单位，基于图像的数字化测量结果计算得到。本数据集曾用于一项已发表研究，该研究得出结论：毛叶苕子的种子尺寸与通过秋季目视活力评分衡量的幼苗活力紧密相关。
