Catalogue - French Natural Accessions (regional scale)

458 individuals were collected randomly from 168 natural populations located in the south-west of France and inhabiting ecologically contrasted habitats, in particular three contrasted climates (oceanic climate, Mediterranean climate, and mountain climate) (Frachon et al. 2018). The 168 geo-localized populations were characterized for a unique set of ecological factors, including climate, edaphic properties, bacterial communities (soil, root, and leaf), plant communities and human activities including urbanization (Bartoli et al. 2018; Frachon et al. 2018; Frachon et al. 2019; Roux et al. 2023). Long-read whole genome sequences are available for 24 of these accessions (Wlodzimierz et al. 2023).

Four successive SSD (Single Seed Descent) generations were carried out for each individual, followed by a bulk multiplication of two plants that provided the seeds available for distribution.
