Interpretive Summary: Quincy is a new pinto bean cultivar with higher yield potential than existing pinto bean cultivars. This cultivar also possesses resistance to endemic virus diseases in the Pacific Northwest (CA, ID, OR, WA). The main attraction of Quincy is its excellent yield performance under multiple stresses which provides some insurance of obtaining economic yield under sub-optimal conditions. Quincy provides growers in the PNW region and in Colorado, Wyoming, and Nebraska with a new cultivar option for increasing on farm yield of pinto bean production.
Technical Abstract: “Quincy’ pinto bean (Phaseolus vulgaris L.) was developed cooperatively by the Washington Agricultural Research Center and USDA-ARS and released in 2004. Quincy is a mid season maturity, virus resistance pinto bean and is adapted to western states of the U.S. Quincy has the combined I and bc-22 genes, which together condition resistance to all known strains of BCMV and Bean common mosaic necrosis virus (BCMNV) and complete resistance to BCTV. Quincy has a semi-upright Type 3 plant growth habit that varies from prostrate to more upright depending upon growing conditions. It also exhibits a high level of tolerance to root rot caused by Fusarium solani. Quincy yielded 21% and 48% higher than Othello and ‘Burke’, respectively, under multiple stress conditions of low residual soil nitrogen, low soil moisture, and heavy root rot pressure. Quincy yielded 10 and 20% higher yield than Burke and Othello, respectively and was comparable to other high yielding pintos when grown in Colorado. Seed of Quincy is slightly larger than Othello 43.7 vs 39.6 g per 100 seeds. Quincy is an acceptable canner as determined in canning trials.
