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.
