Plant Breeding and Genetics is a paper in the series on The Need for Agricultural Innovation to Sustainably Feed the World by 2050. Humans depend on plants for food, feed, fiber, and fuel—as well as less tangible aspects of life such as aesthetics and environmental stability.

This Special Publication describes the biology and agronomic practices in alfalfa that should be considered in developing coexistence strategies to allow growers to have choices, specifically between genetically engineered (GE), conventional, and GE-sensitive markets in the United States.
