%X The genetic structure of the ¡°Badda¡± common bean cultivated at Polizzi Generosa, a village of Sicily (Palermo, Italy), was investigated using biochemical and molecular markers. Seed storage protein analysis by using SDS-PAGE, confirmed the attribution to the Andean gene pool. Simple Sequence Repeats (SSR) (or microsatellite) molecular markers provided useful information on genetic variation and relationships between ¡°Badda bianco¡± and ¡°Badda nero¡± morphotypes. Based on SSR data, the nine accessions examined were grouped in three sub-clusters. The first sub-cluster included all the accessions belonging to the ¡°Badda bianco¡±. Conversely, ¡°Badda nero¡± was constituted by two well-distinguished sub-clusters, one of them forming a well-separated branch. This result suggests that two constitutive nuclei contributed to the genetic background of ¡°Badda nero¡±. Moreover, technological and nutritional data evidenced a good seed protein content (mean value 240.7 g kg £¿ 1) and differences in seed hydration rate among accessions. Knowledge of genetic structure appear to be fundamental in planning safeguard strategies of an appreciate landrace such as the ¡°Badda¡± bean.
