The pinto bean type is in high demand by consumers in the North-Central Mexico.

The plant 'San Rafael' is indeterminate habit prostrate short guide, short crop cycle photoperiod neutral reaction (can be planted any time of year and latitude without its cycle is changed). San Rafael presents resistance to major leaf diseases that occur in the plateau, such as halo blight, anthracnose and rust. The grain is of type pinto, oval, medium size, with tolerance dimming (long shelf life), grain type of high commercial value. For its neutral response to photoperiod, 'San Rafael' allow their exploitation in different time windows, expanding the supply of fresh bean in the year. 'San Rafael' suits production systems under irrigation and temporary in the highlands and the northwest region.
