The common bean (Phaseolus vulgaris L.) is the most important food legume in the tropics. It is an inexpensive source of proteins and minerals for almost 400 million people, mainly from Africa and Latin America. It is generally cultivated by small farmers and subject to conditions limiting their productivity. Drought affects 60% of bean crops around the world and can cause from 10% in productivity losses to a total of 100% in some cases.Researchers from the Universitat Autònoma de Barcelona and the Bean Programme at the International Center for Tropical Agriculture (CIAT) in Colombia have identified drought-resistant genotypes and the morpho-physiological characteristics related to this resistance. The experiments were conducted in Palmira, Colombia, from June to September in 2012 and 2013, and the results were recently published in Frontiers in Plant Science.
