PROGRESS IN THE STUDY OF GENETIC RESOURCES OF Phaseolus BEANS IN PANAMA
A germplasm exploration carried out in the western part of the Chiriqui province in Panama resulted in the disclosure of 15 populations for the four Phaseolus bean species reported as non-cultivated or wild for this country: P. costaricensis, P. dumosus, P. lunatus and P. tuerckheimii. Some aspects of conservation of these species are discussed starting with the small acreage of the original habitat for three species. While the areas of natural occurrence of P. lunatus below 1,300 m are being reduced because of cattle ranching, the tropical montane forest with dry season where the other three are thriving, is being replaced by cool climate vegetable crops and urban expansion. The collections of P. dumosus displayed an unusual variation in seed traits, possibly resulting from natural crosses with other species, thus offering the possibility for use as bridge in breeding.
