Research Project: Optimizing the Convenience, Nutrition, and Taste of the Yellow Dry Bean (Phaseolus vulgaris L.) to Promote Pulse Consumption in the U.S.

Location: Sugarbeet and Bean Research

Project Number: 5050-21430-011-04-I
Project Type: Interagency Reimbursable Agreement

Start Date: Mar 15, 2017
End Date: Mar 14, 2021

Objective:
1) Establish and assess the genetic diversity of a panel of 200 yellow bean genotypes from around the world of both Andean and Middle American origin. 2) Phenotype the yellow diversity panel for convenience (cooking time), nutrition (dietary fiber, resistant starch, iron bioavailability, polyphenolics, and protein), and taste (texture, seed coat perception, flavor intensity). 3) Phenotype and conduct QTL mapping for iron bioavailability and cooking time in a yellow bean recombinant inbred inline population segregating for these traits.

Approach:
1) Genotype by sequencing of a diversity panel and a RIL popultions. 2) Phenotypic evaluation of both populations over two field seasons in Michigan for end use quality traits, including cooking time, dietary fiber, resistant starch, iron bioavailaiblity, texture and taste. Use phenotypic and genotypic data for QTL analysis, GWAS, and to select parents for breeding.
