A plant that produces both tomatoes and potatoes, called the TomTato, has been developed for the UK market, reports BBC. Ipswich-based horticultural firm Thompson and Morgan said the hybrid plants were not genetically modified. "Many people don't have that much space in their gardens and I imagine this sort of product would appeal to them," - Thompson and Morgan director Paul Hansord noted. According to him, the tomatoes were tastier than most shop-bought tomatoes and said the plant had taken a decade of work. "It has been very difficult to achieve because the tomato stem and the potato stem have to be the same thickness for the graft to work," he said. The firm stressed the plants last for one season and by the time the tomatoes are ready for picking, the potatoes can be dug up. It added both ends of the plant had been tested for alpha-solanine - a poison that can be produced in both crops depending on growing and storage conditions - and it had been certified as safe. A similar product, dubbed the "Potato Tom", was launched in garden centres in New Zealand this week.
