Tepary Beans May Hold Key to Adapting Bean Crops for Climate Change

Researchers at the University of Saskatchewan and Michigan State University published a study on how tepary beans adapt to heat stress. They hope that crossing the tepary beans with common beans will help this important legume protein source become more tolerant of the increasingly harsh conditions brought on by a changing climate. Scientists predict that by 2050, the major regions growing common beans may be unsuitable and the overall nutritional quality of the crop will likely be reduced. While the tepary beans are resistant to temperature stress, they are not as disease resistant, so researchers are looking to combine desirable traits by crossing the two types of beans.
