Radiation Breeding

Though poorly known, radiation breeding has produced thousands of useful mutants and a sizable fraction of the world’s crops, Dr. Lagoda said, including varieties of rice, wheat, barley, pears, peas, cotton, peppermint, sunflowers, peanuts, grapefruit, sesame, bananas, cassava and sorghum. The mutant wheat is used for bread and pasta and the mutant barley for beer and fine whiskey.

The mutations can improve yield, quality, taste, size and resistance to disease and can help plants adapt to diverse climates and conditions.

Dr. Lagoda takes pains to distinguish the little-known radiation work from the contentious field of genetically modified crops, sometimes disparaged as “Frankenfood.” That practice can splice foreign genetic material into plants, creating exotic varieties grown widely in the United States but often feared and rejected in Europe. By contrast, radiation breeding has made few enemies.
