Description
Jorge Tobaru and seven colleagues catalogue the bean diversity held by farmers in the Peruvian Amazon, in this 2026 PLOS ONE genetics study. Common bean is a world staple, yet Amazonian varieties were poorly documented. The team measured eighteen visible traits in hundreds of samples and read tens of thousands of genetic markers in even more.
Two great family lines appeared, matching the bean's Andean and Mesoamerican origins, each splitting further into subgroups. Visible variation was wide, from flowering time to pod size, and no duplicate samples were found. Low cross-breeding between plants fit the bean's self-pollinating habits. The collection is a rich reserve for breeders seeking beans adapted to Amazonian conditions.
