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.
