This research was funded by Universidad Nacional del Nordeste PI18PD01 y la Agencia Nacional de Promoción Científica y Tecnológica-Universidad Nacional del Nordeste PICTO-UNNE 2018 N°020. Donations of materials used in this study by family farmers were done with the corresponding informed consent. Participants were informed about the purpose of the research and their right to withdraw from the study at any time without any consequences.

: . Passports of old and new accessions of peanut collected and analyzed in a peanut diversity microcenter in Argentina. Average measurements of the 22 characters (with their units of measurement) and geolocation (latitude and longitude) of old and new peanut accessions in Corrientes Province. For old accessions, location is based on precise information recorded in the original germplasm collection passports, including designated localities, road numbers, and distances to known landmarks, most of which are still identifiable; accessions without precise localities were marked as “Corrientes Province (no data)”. For new accessions, geolocation data were recorded directly during fieldwork. The label “Accession number” refers to the number assigned to each accession in this study, Peanut Entry Record (REM) and taxon (subspecies) of collection are indicated for each accession; “REM” refers to the registration number at Manfredi Experimental Station of the National Institute of Agricultural Technology (INTA), and “CTES” refers to the registration number at the Botanical Institute of Northeast (IBONE). Each character is accompanied by its unit of measurement (cm, mm, and g); “number” refers to a quantity (e.g., seed number), and “nominal” refers to nominal values on a scale. Finally, the last two columns indicate the geolocation of the accessions.

: . Composition of the collections according to the phenogram of both collections. This table presents the proportions of old and new peanut accessions in the phenogram. The columns include the total accession count, old accessions and their proportion in the total, new accessions and their proportion in the total, the representation of the proportions of old and new accessions, and finally the proportional difference between old and new accessions.

: . The descriptors for each measured trait are shown in Supplementary Table (ESM_3). The descriptors were based on the guidelines published by the IBPGR ICRISAT ( ) and Royo and Seijo (2022).
