摘　　要：The protein intake of the population in the Yucatan Peninsula is based upon the different forms of beans naturally developed. The different ecotypes of creole beans that are grown traditionally have been displaced by improved varieties, thereby turning into a risk of losing a valuable source of germ-plasma. The present study is aimed to identify, collect and preserve several bean species genetic resources grown in Campeche, Mexico, in addition to the development of an identification card with the main phenotypic characteristics and yield components. A total of 33 different samples were collected from nine different municipalities statewide;out of those, 15 were Phaseolus vulgaris and 18 Phaseolus lunatus. The collected samples diversity is reflected in the range of growth habits from the bush to the indeterminate climbing species, being these the most representative with about 29 samples, many of those because of the way the planting is carried out, which is traditionally performed in association with the cultivation of corn. Early samples were identified in this diversity with their cycle ranging from 60 to 120 days after emergence. Samples of Phaseolus lunatus with 1.35 to 2.86 t/ha yield potential were also obtained.The protein intake of the population in the Yucatan Peninsula is based upon the different forms of beans naturally developed.
