WebThere have also been extensive applications in the breeding of cultivated plants. One of the important events in this field was the discovery (Blakeslee and A. G. Avery, 1937) that doubling of the chromosome set in plants may be induced by the use of colchicine. Winge’s interpretation of polyploidy grew out of a comparison of the Webmost important crop plants are of known or supposed allopolyploid origin. The general occurrence of polyploidy in the angiosperms has led to a detailed study of the causes of chromosome doubling in gametes and egg cells.
