Research efforts in northern and eastern Europe were increased and the agronomical characteristics and industrial uses of crambe were intensively studied. By successive selection within C. abyssinica, conventional breeding started in the 1950s in some European countries. Hereby improved strains were introduced to Canada and the United States.
The study of crambe's agronomic traits and industrial applications was intensified in northern and eastern Europe during research efforts. This led to the development of improved strains through conventional breeding methods, which were then introduced to Canada and the United States.
