Estado actual de los recursos genéticos de Phaseolus coccineus (Fabaceae) en México

Background and aims:The ayocote bean (Phaseolus coccineus L.; 2n = 2x = 22), is a species native from Mexico that has been domesticated for human consumption, however there is little few information about its qualities, so the aim of this work consisted in investigating and gathering the most relevant aspects including: its center of origin and domestication, geographical distribution, patterns of morphoagronomic and genetic diversity, productivity, further of beneficial properties of its consumption, it should be noted that its distribution in America ranges from the South from the United States to Northern Argentina. M&M: Different sources of information, both printed and digital, were consulted, which included: libraries, internet databases, manuals and technical reports, as well as personal interviews with experts and producers. Results: The results indicate the current situation of the genetic resource of the ayocote bean both in Mexico and in the world, which includes the different uses that the species has been given, for example its study in areas as diverse as forage production, bioremediation of soils, resistance to low temperatures, until introgression with other Phaseolus species. Conclusions: Due to the various interesting characteristics that the ayocote bean has, it is suggested to develop studies aimed at characterizing genetically and morphoagronomically a greater number of populations of the species, with the aim of generating improved varieties of common bean according to their production areas from germplasm of P. coccineus.
