Dry Bean Breeding Project

Research

Slow Darkening Pinto Bean

Colorado pinto beans are prized worldwide because they have a bright cream background color. However, North Dakota is poised to introduce new pinto varieties that possess a novel gene, termed “slow darkening” (SD), which conditions bright cream pinto color, and reduces discoloration in storage. Because these new varieties will likely not be adapted to Colorado growing conditions, there is a need to develop SD varieties for Colorado. The goal of this project is to speed up the development of pinto bean varieties that possess the SD trait with disease resistance, upright architecture, and high yield potential. The Dry Bean Breeding Project at Colorado State University has initiated crosses in 2012 to incorporate the SD trait into breeding lines, however, under current funding it will take 6 to 8 additional years to complete. Funds from SCCGP will allow the project to complete the development of SD varieties by 2015, thus allow the Colorado bean industry to remain competitive in both the U.S. and global markets. A conservative impact would equate to an increase in crop value between $1.6 and $3.2 million annually and prevent the erosion of competitiveness for the Colorado bean industry.

The Common Bean Coordinated Agricultural Project

The Common Bean Coordinated Agricultural Project (BeanCAP) will significantly impact the future direction of research by providing new tools and research directions for this important nutritional and commodity crop. The first market-class-specific markers, whose value will extend well beyond the project duration, will be a major outcome affecting all bean research. When genotypic data, generated by using these markers, is coupled with nutritional profiling data, also generated by the project, species-wide and market-class-specific loci affecting the nutritional traits will be discovered. This will set the stage for significant common bean improvements for years to come. All public US bean breeding programs will also be supported by 1) a genotyping program that will aid the discovery of genetic factors controlling traits of local agronomic importance; and 2) conversion of high throughput markers into low cost makers for day-to-day use in breeding programs. The nutrition, genetic, and genomic scientists will coordinate the development of an extension Community of Practice that will utilize high-quality animations and other multimedia to educate the general public and educational communities about the biology of nutrition and how genetics/genomics technology assists with the improvement of nutritional traits. The BeanCAP will also initiate a modern plant breeding training program focusing on early career recruitment and practical breeding/genomics training that illustrates, as an example, how the integration of genomic and phenotypic data can be used to improve nutritional traits in plants. This will provide a stream of students interested in filling the plant breeding human resource pool.
