Plain language summary
Pinto bean is a type of dry bean grown in Canada and exported to USA and Mexico. AAC Expedition is a new cultivar registered in 2018 for commercial production in Canada. Seeds of most pinto bean cultivars undergo darkening or browning after harvest and during post-harvest storage, and darkened seeds are considered as poor quality. Seeds of AAC Expedition have a lighter seed coat colour compared to Island (a currently grown pinto bean cultivar), and retain their light seed coat colour for one year or longer depending on the storage conditions. The improved seed coat colour of AAC Expedition will ensure that Canada has continued market access.
AAC Expedition is a high-yielding pinto dry bean (Phaseolus vulgaris L.) cultivar with a semi-upright, indeterminate bush (type IIb) growth habit, large seed size, low percentage of hard seed, and bright seed coat colour. Its improved seed quality traits, particularly its bright seed coat colour, low percentage of hard seeds after soaking, and high yield potential, will make AAC Expedition a preferred pinto bean cultivar for commercial production. AAC Expedition, developed by the Agriculture and Agri-Food Canada Lethbridge Research and Development Centre, Lethbridge, AB, is well suited for commercial production under irrigation in Alberta and Saskatchewan.
