Knowledge of common bean (Phaseolus vulgaris L.) landrace resources maintained in situ and ex situ in Basilicata region

The implementation of a monitoring of the genetic resources still conserved in situ and ex situ allows the identification of cultivated ecotypes stable in particular environments through phenotypic selection by participatory (researchers and farmers) breeding. . Common bean (Phaseolus vulgaris L.) is a typical edible food legume of Basilicata Region (Southern Italy) which are consumed as dry seeds or as whole legumes. In the present study 276 common bean genotypes (determinate and indeterminate grown habit) collected and cultivated in the National Park of the Agri Valley in Basilicata were evaluated, using agro-morphological IPGRI and UPOV traits, according to descriptors for common bean, in three Lucanian diversified environments from 2018 to 2020.
