Drought and the bean stalk
By Brad Hooker
A team of UC Davis researchers is raising the roof to understand and measure exactly how the two most popular types of dry beans deal with drought stress.
Their goal is to develop a bean that can better withstand the effects of drought and climate change in California and beyond.
Dry beans in California
Dry beans are important for California, which annually produces 60,000 tons of them on about 50,000 acres. In times of drought, crops like dry beans are often the first to be targeted for fallowing, and they have already been significantly reduced in the parts of California hit hardest by the severe drought.
Although lima beans and the common dry bean, which includes kidney, pinto and other varieties, use a considerable amount of water to achieve high yields, they already have some degree of drought tolerance built into their genes.

The best climate-change breed
Gilbert and Medina are confident that their large collection of drought-challenged bean plants will yield the data needed for selecting and developing the best candidates for a new generation of dry bean varieties that can survive drought conditions.
