| Abstract | Black bean (Phaseolus vulgaris L.) consumption is increasing in the USA. One of the major challenges faced by breeders is to develop superior black bean cultivars to meet the demands of the canning industry. Processors require beans that take up water quickly during pre-canning soak and beans that retain their black color after canning. To properly assess canning quality requires expensive and detailed measurements of the canned product, often not possible for bean breeders. The objective of this research was identify quantitative trait loci (QTL) in a black bean recombinant inbred line (RIL) population for canning quality traits related to water uptake, color retention, and anthocyanin concentration. The parental lines from which the population was developed, Black Magic and Shiny Crow, contrasted in water uptake and color retention. These cultivars also differed in seed coat luster, controlled by a single gene, Asp. A medium-density linkage map of 1,449 markers and a distance of 1,660 cM was developed from this RIL population. The map was aligned to the bean genome sequence V1.0 by using sequence information associated with the Diversity Arrays Technology markers. QTL analysis revealed that the region near the Asp gene on chromosome Pv 07 is the major determinant of water uptake, explaining up to 49 % of the phenotypic variation. A group of QTL for color retention-related traits was found at the upper region of Pv 11, explaining up to 30 % of the phenotypic variation. A smaller effect QTL clustered on Pv 5 co-localized with a QTL for canned bean anthocyanin concentration and explained less than 10 % of the phenotypic variation. These color-related QTL have marker-assisted selection potential for bean breeders interested in enhancing color retention and anthocyanin concentration of processed black beans. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
