RESUMO:

The common bean (Phaseolus vulgaris L.) is cultivated in over 100 countries, with 63% of the global production concentrated in just five countries, among which Brazil is the largest producer and consumer. Despite this, the growing demand has surpassed the productive capacity, resulting in the importation of around 100,000 tons annually. To increase productivity, cultivation areas have become more technological, utilizing genetic improvement to obtain more uniform and productive cultivars. However, over time, genetic erosion occurs, losing important agronomic characteristics such as productivity, stress resistance, and nutritional quality. Heirloom materials, with significant genetic variability, can naturally provide these characteristics. The genetic diversity of common beans is studied through morphological, agronomic, and molecular characterization, which is essential for genetic improvement and the conservation of existing variability. The genetic variability of seeds is crucial for the adaptability of plants to adverse environmental conditions and the selection of desirable traits in agriculture. In the context of extensive and family farming, genetic diversity is exploited to improve resistance to pests and diseases, ensuring food security. Heirloom seeds, cultivated and preserved by family farmers, are fundamental for food security, income generation, and maintaining rural populations, as well as contributing to genetic conservation. Studying the heirloom bean varieties cultivated locally is necessary to understand their productive potential, physiological quality, and nutritional contents, helping to preserve these seeds and reduce dependence on imports. This work highlights the importance of small producers in the preservation of heirloom seeds and agricultural sustainability, promoting an increase in local production and ensuring quality and food security. This study aimed to determine the production potential, genetic, physiological, and nutritional qualities of seeds from heirloom bean varieties produced by local farmers in Alta Floresta, Mato Grosso. Specifically, seeds from heirloom varieties were collected, and their physiological quality, productive potential, genetic and reproductive characteristics, and nutritional contents were evaluated.
