A SUBSTANTIAL number of cultivated plants of major importance are polyploids; for example, potato, alfalfa, peanut, sweet potato, tobacco, cotton, wheat, soybean, oats, and sugarcane (22). These range from the more or less typically heterozygous autopolyploids such as the commercial potato (2, 7), to the classic homozygous amphipolyploids such as common wheat (22). When diploids related to these cultivated forms exist, the diploids are not in most cases able to compete economically with their polyploid relatives. Thus each of these particular crop plants appears to have gained substantial advantages from polyploidy.
