"UK: "New black tomato at Marks & Spencers"
Tomatoes from the strain 'Indigo Rose' have more anthocyanins, dyes that give the tomato it's darker color and have an antioxidant effect. Damage from free radicals is decreased with this strain. Geneticists are also working on similar fruits. The British 'John Innes Centre' are testing purple genetically modified tomatoes in Canada, although these will most likely not hit North American markets for at least two years.
