Bolivian tuber species like potato (Solanum tuberosum), native potato (Solanum sp), Oca (Oxalis tuberosa Molina), Olluco (Ullucus tuberosus Caldas), and Isaño (Tropaeolum turosum Ruíz & Pav.) hold extraordinary nutritional value and cultural significance, particularly within the Andean region. This study examined the mineral composition of Bolivian tuber species as an essential step toward understanding their nutritional significance and potential contributions to addressing dietary deficiencies. The research involved detailed analysis of diverse tuber cultivars, uncovering distinct mineral profiles across species. Native potato shows high levels of nitrogen (N), potassium (K), phosphorus (P), and magnesium (Mg) levels, alongside moderate micronutrients like iron (Fe) and zinc (Zn). Commercial potatoes exhibited prominence in N, P, and K, with moderate Fe, Zn, and manganese (Mn) levels. Oca, Isaño, and Papa Lisa displayed unique mineral concentrations, offering potential nutritional benefits. Intricate correlations and significant variances among elements highlighted the diverse mineral compositions among these tuber species. Multivariate analyses emphasized distinct mineral profiles unique to each species, revealing significant compositions of isaño and papa lisa's. The Multitrait Genotype- Ideotype Distance Index (MGIDI) identified isaño jaspeado, isaño and an unnamed native potato, AXT2, as promising ideotypes due to their exceptional mineral compositions. These findings provide comprehensive insights into Bolivian tuber species' various mineral compositions, underscoring their nutritional significance and potential in targeted breeding for improved dietary support and enhanced food security.
