The conservation and regeneration of seed collection of runner bean of the germplasm bank from INIFAP requires knowing the weather sites of domestication of the species. In 2010, at the Experimental Station of Valle de Mexico, were registered the passport data, locality, state, altitude, geographical coordinates, precipitation, minimum and maximum temperature and annual average of such sites. For this data and maps from Garcia and CONABIO were used (1998) 1:1 000 000 scale, the "software" GIS ARC-INFO, version 8.0 and the "hardware" SPARCstation, SUN OS, Version 5.5.1 from the Laboratory of Geographic Information Systems from INIFAP. The 798 accessions in the collection were domesticated in 140 sites in 13 states of the country, 80% at altitudes from 1 500 to 2 500 masl, precipitation from 500 to 1 000 mm annually. The wide range of minimum and maximum temperature separated sites into: very cold, -5 to -1 °C at night and 21 to 31 °C during the day, cold 3 to 5 °C at night and 25 to 33 °C during the day, and semi cold 6 to 9 °C at night and 25 to 37 °C in the day. The distribution of native varieties of the species are concentrated in high and humid areas of the country, but also adapted to semi-arid with little rainfall and very warm.
