is a strategic crop for meeting the world s food and nutrition security as well as economic empowerment.
Larvae-injured common bean
plants are yellowed and their leaves progressively dry (Amante & Figueiredo Junior 1971).
In addition to yield and other agronomic features, the evaluation of genetic materials for improved common bean
seed quality is necessary in the production of the crop since a cultivar with poor bean quality may be rejected by processors and consumers regardless of agronomic superiority .
The Gates Foundation is reportedly funding additional research by Purdue to determine if PICS (now dubbed Purdue Improved Crop Storage) can help control "storage insect pests of other crops including maize, sorghum, wheat, rice, peanut, common bean
, hibiscus seed, mung bean, pigeon pea, and bambara groundnut.

The project, titled W-2150 Breeding Common Bean
(Phaseolus vulgaris L.
The topics include the genetic basis of disease resistance in maize, molecular breeding for Striga resistance in sorghum, the organization of genes conferring resistance to anthracnose in the common bean
, enabling tools for the modern breeding of cowpea for biotic stress resistance, marker-assisted selection for disease resistance in lettuce, and the genetics and gene-mapping of disease resistance in brassicas.
Genetic breeding is a strategy often used to increase the mineral concentration in common bean
Two projects funded by the foundation were highlighted as the case: the HOPE project (Harnessing Opportunities for Productivity Enhancement of Sorghum and Millets) in sub-Saharan Africa and South Asia which seeks to increase by 30% the productivity of sorghum and millets in 200,000 farmers' fields; and the Tropical Legumes I & II project which aims to enhance productivity of six legume crops (groundnut, cowpea, common bean
, chickpea, pigeonpea and soybean) by at least 20% through improved cultivars and management practices and the development of markets and value chains.
Epidemiological studies showed a strong association between increased consumption of the common bean
(Phaseolus vulgaris)--which includes black beans, pintos, and others--and a reduced risk of chronic diseases, including type II diabetes.
After many years of exploiting existing diversity within the genus Phaseolus (beans), ARS researchers in Mayaguez, Puerto Rico, have been able to combine genes for resistance to heat, drought, and disease and have released two high-yielding, stress-tolerant black bean varieties; two heat-tolerant kidney bean lines; and rust-resistant, heat-tolerant common bean
