Sažetak
Nowadays, traditional landraces face real risk of disappearance and with that unique genetic resources will be lost. On farm conservation, with farmers’ engagement through participatory breeding approaches, may halt this loss by improving those landraces and increasing their market value. Having this in mind, members of our team engaged in a field expedition to the Central region of Portugal to collect enduring landraces. In this region farmers grow maize landraces, known for its good bread quality, in association with common bean local varieties, in a traditional intercropping practice. These collected landraces may represent important sources of genes and genes combinations not yet available for crop quality breeding programs. The study of the landraces’ associated genetic diversity is fundamental for an efficient conservation and management of these interesting plant resources on effective quality participatory breeding. Under the framework of the “SOLIBAM” European project, we characterized the genetic diversity present on the collected maize and beans Portuguese landraces as a starting point to evaluate the changes, at the molecular level, caused by different management (sole crop vs. intercropping) and breeding practices (on-station vs. on-farm participatory selection). This diversity characterization provided also, in association with the original quality evaluation, important information for the selection of landraces to field trial under specific cropping systems.
