| dc.description | Lima bean (Phaseolus lunatus var. lunatus) is the second most cultivat-ed and consumed species, from Phaseolus genus, in Brazil as compared to common bean (Phaseolus vulgaris). This plant species can be found widely and with high diversity in all ecogeographic regions, highlight-ing the Northeastern, Brazil, where lima bean presents greater genetic diversity in landrace genotypes. Unfortunately, national surveys do not discriminate P. lunatus and Vicia faba (known as “fava”). Thus, the avail-able information become unclear how are the representativeness and im-portance of each of these legume species in Brazil. The highest diversity of beans, in general, is found in the Northeastern region, Brazil. Since this region is considered as the poorest region, beans are an important part of diet to population, mainly due to their high content of protein. However, there are particularities about lima bean, such as its representa-tiveness in regions of high altitude, being mostly the main source of pro-tein. In other regions, lima bean usually represents a special type of food. Regarding the origin of the Brazilian germplasm of lima bean, studies indicate the presence of genotypes from three known gene pools, and the geographic location of Brazil favors this assumption. It can support the hypothesis that Brazil is a center of domestication. There is information about wild genotypes collected in the Central region of Brazil. In terms of ex situ conservation, the Active Germplasm Bank of Phaseolus from Federal University of Piauí (BGP/UFPI) was established in 2003, and conservates landraces obtained from local smallholders and sellers. Cur-rently, the BGP/UFPI has 1,345 genotypes (updated in February 2020) mainly obtained in Brazil. | |
