Resumo(s)
Common bean (Phaseolus vulgaris L.) is a staple legume in Portugal, yet its diverse local germplasm remains underexploited in breeding programs. This study evaluated a Portuguese collection of over 250 accessions, integrating morphological descriptors and nutritional profiles to assess variability and identify promising accessions for crop improvement and valorisation. Despite the recognised importance of grain nutritional composition in determining food quality, it has often been overlooked in conventional selection processes. Given the growing global population and the urgent need to ensure food and nutrition security, the production of nutritionally superior grains must become a priority. The evaluated collection includes accessions representing different geographical regions of Portugal capturing a wide range of edaphoclimatic conditions and allowing exploration of their impact on seed quality. Key traits analysed included seed size, days to flowering, protein content, antioxidant capacity, mineral composition, and antinutritional factors.
