Blue tomato stems, where they are not eaten and would not provide any health benefit. With this in mind, researchers at Oregon State University have produced blue tomatoes using conventional breeding techniques, cross-pollinating domestic tomatoes with wild varieties that possess the "Anthocyanin fruit" (Aft) allele. As of the 2012 growing season, Oregon State University developed blue tomato seeds became commercially available under the cultivar name "Indigo Rose". The blue color is produced mostly by the anthocyanin petunidin on the outside of the tomato where the fruit is exposed to direct sunlight. The shaded side of the fruit is green when unripe, red
