Research Objectives
- Evaluate dietary fiber (total, soluble and insoluble fiber), trypsin inhibitor activity and oligosaccharides in dry beans grown in Manitoba
- Investigate the effect of cultivar and environmental factors including growing location and year on dietary fiber (total, soluble and insoluble fiber), trypsin inhibitor activity and oligosaccharides
Project Description
Each year, approximately 100 crosses are made at Morden, and, while much attention is given to yield and disease resistance, and seed quality, the nutritional profiles in the breeding materials have not been fully characterized. Quality attributes of dry beans for human consumption include nutritional composition, cooking quality and physical characteristics. High fiber intake is linked to lowered blood pressure, cholesterol and risk of heart attack and colon cancer. Although it is well known that beans are rich in dietary fiber, little information is available on how cultivar and environment affect dietary fiber (total, soluble and insoluble fiber) of dry beans grown in Manitoba. Previous research indicated that cultivar and growing location had significant effect on protein content, seed size, water hydration capacity, cooking quality of Manitoba grown dry beans. Dry beans also contain certain anti-nutritional factors (trypsin inhibitors and oligosaccharides). There is a need for genetic improvement to reduce the concentration of these anti-nutritional factors in dry bean seeds; however, information on the availability of these anti-nutritional factors in dry bean cultivars and the influence of environmental factors on these traits is necessary for an effective genetic improvement program. Knowledge on the cultivar and environment interaction for nutritive traits of dry beans grown in Manitoba will assist breeders in improving quality of beans in their breeding programs, which will in turn improve production practices for better seed quality.
