Exploring the role of local heirloom germplasm in expanding western Washington dry bean production

Abstract

Increasing production of dry beans (Phaseolus vulgaris L.) could contribute to the sustainability of regional agricultural systems. This study in western Washington identified 24 distinct dry bean varieties grown in the region for 20–130 years; varieties originated from diverse geographic areas and were maintained because growers valued the culinary, visual, and agronomic traits as well as history and marketability. Primary barriers to increased production were access to scale-appropriate equipment and drying beans in the field prior to harvest. Locally conserved germplasm may have value in participatory plant breeding projects that recognize the contributions of regional farmers.
