Molecular diversity in Ligurian local races of common bean (Phaseolus vulgaris L.)

Eight varieties of Ligurian common beans (Phaseolus vulgaris L.) were analysed using molecular approaches. Results were compared with two commercial cultivars (‘Cannellino’ and ‘Borlotto’). Data suggest that all Ligurian bean varieties have a low genetic variability and are very close to the commercial varieties. In particular, the three ‘Bianco’ varieties showed a molecular affinity, probably due to their common genomic origin.
