In 2011 Jim Myers did something no one had done before. The Oregon State University vegetable breeder released the first purple tomato containing the same healthy compound found in blueberries.
The Indigo Rose tomato, which took Myers, a professor in the OSU College of Agricultural Sciences, and his team 10 years to develop, took the market—and other breeders—by storm. People liked the tomato's novelty but the benefits from the anthocyanins in the skin were the draw. Interest in anthocyanins, the pigment that turns the tomato fruit purple and contains healthy antioxidants, was peaking with the public.
Myers and his students painstakingly crossed—often by hand from male stamen to female style—plants that showed potential to express the purple gene in their offspring. Year after year, he and his team selected the best of the best grown in the field for observation and crossed those until he got a purple tomato good enough to release to breeders and home gardeners.
Work started in earnest to breed a tomato that combined the health benefits of anthocyanins with the characteristics of a good home-grown tomato, they hoped with some disease distance. Once an edible tomato with some purple was produced, the work turned to field evaluations. For 11 years, Myers and his team planted tomato starts and watched them grow and produce. Every year, they took the tomatoes with the best purple expression and crossed them.
