Dr. Robin Groose, Associate Professor of Genetics, Agroecology and Plant Breeding, breeds legumes for adaptation and productivity in Wyoming. He has developed cultivars of alfalfa and annual medic. Current focus is on winter feed pea to be grown in rotation with wheat in dryland farming systems of the Central Great Plains and as a partial replacement for fallow. The goal of this breeding effort is to produce genetically improved peas for more sustainable and profitable farming/ranching that integrates cereal and livestock production. New Wyoming-bred pea lines are now being increased for release as high-yielding, multiple-use pea cultivars that can be grown for livestock feed as either forage or grain. Groose is also developing winter-hardy food peas adapted to Wyoming.
