Pollen and ovule production data of ancestral and descendant populations of Viola arvensis in four location of the Parisian region

This dataset has been obtained while phenotyping ancestral and descendant populations of four locations of the field pansy (Viola arvensis). Ancestral populations were collected in the field in 90's-2000's and conserved in seedbanks and descendant were collected in the field in 2021. A first generation was grown in common garden in 2021. Using mothers from the first generation, a second generation composed of families of 5 siblings was grown in controlled greenhouses in 2022. We measured pollen and ovule productions in this second generation. Measurements were made following the methods described in this article: https://doi.org/10.1093/aob/mcaf203.
