We hypothesized that cacao phenotypic and genotypic diversity could provide new insights to decrease Cd accumulation in cacao beans. Nine cacao rootstock genotypes were evaluated for up to 90 days under 0, 6, and 12 (mg·kg^-1) of CdCl₂ exposure and Cd content and plant growth dynamics were measured in leaves, stems, and roots. Data revealed that all cacao genotypes studied here were highly tolerant to Cd, since they presented tolerance index ≥ 60%. In shoots, EET61 and PA46 presented the higher (~270 mg·kg DW^-1) and lower (~20 mg·kg DW^-1) Cd concentration, respectively. Accordingly, only the EET61 showed an increase iPlants (Basel, Switzerland)Unveiling Cacao Rootstock-Genotypes with Potential Use in the Mitigation of Cadmium Bioaccumulation.PMC10458809FCB-11-17 ProjectBPIN 20013000100255Leon-Moreno CEGalvis DARuiz RJaimes-Suarez YYRojas Molina JCarvalho FELfalseUnveiling Cacao Rootstock-Genotypes with Potential Use in the Mitigation of Cadmium Bioaccumulation.The accumulation of high cadmium (Cd) levels in cacao beans (<i>Theobroma cacao</i>) generate several commercial and health issues.
