In Chiapas, Mexico there is a demand of more than 8 000 t of red bean, mainly to meet the needs of local consumption of a population close to 1 000 000, including one of the most important population of temporary or permanent immigrants from Central America. In response to this demand, in 2013, the Bean Program from the National Institute of Forestry, Agriculture and Livestock (INIFAP), in the state of Chiapas, generated the Sangre Maya variety developed by hybridization from a triple cross at the International Center for Tropical Agriculture (CIAT) and several cycles of selection in different environments and locations. In Chiapas, this variety was evaluated in nine environments from the center of the state, from 2010 to 2012, to determine its yield, disease tolerance and response to acid soils. Sangre Maya exceded in 9 and 40.4% the yield from control Bribri and Creole Coloradito, respectively. Also, the new variety had the lowest incidence (10%) of the golden yellow mosaic virus from bean, while Bribri and Creole Coloradito showed incidences of 30 and 64%, respectively. Additionally, the new variety was evaluated in acid soil with and without lime and showed the best response of grain yield in both conditions of soil management. In 2014, Sangre Maya was registered in SNICS with the final number FRI-088-060314 for commercial use.
