Cherry tomatoes grow on the vine, while white potatoes grow in the soil from the same plant. The concept of grafting related potatoes and tomatoes so that both are produced on the same plant was originally developed cuts of vegetables pdf 1977 at the Max Planck Institute for Developmental Biology in Tübingen, Germany, and although healthy, the plant produced neither potatoes nor tomatoes. The Max Planck Institute for Plant Breeding Research in Cologne produced a plant with fruit in 1994.
As with all grafts, this plant will not occur in nature and cannot be grown from seed, because the two parts of the plant remain genetically separate, and only rely on each other for nourishment and growth. Like most standard types of plant grafting, a small incision is made in the stem of both plants and they are strapped together.
Once the cuts have healed and the plants are joined, the leafy top of the potato plant can be cut away and the roots of the tomato can be removed, leaving the leaves of the tomato plant to nourish the roots of the potato plant. The tomatoes should be ready to harvest after about 12 weeks during the summer months, the potatoes should be ready after the tomato leaves begin to die back, normally in early autumn. Pomato plants have been seen as a new technology to make food production more efficient, as they maximize the amount of crops that can be produced on a piece of land or in a small urban environment like a balcony. This has significant impacts on developing countries like Kenya, where farmers can save on space, time and labour without affecting the quality of their produce by growing pomato plants.
In addition, grafting can improve resistance to bacteria, viruses and fungi, attract a more diverse group of pollinators and provide a sturdy trunk for delicate ornamental plants. The Incredible Edible nursery in New Zealand announced a “DoubleUP Potato Tom” in the same month. Morgan claim that this is the first time the plant has been produced commercially, and director Paul Hansord describes originating the tomtato idea himself 15 years ago in the US, when visiting a garden where someone had planted a potato under a tomato as a joke.
Morgan trialled the hybrid for several years before selling it. Production and grafting of tomtatos begins in a specialist laboratory in the Netherlands, before being shipped back to the UK and grown in greenhouses until they are ready to be sold. In the famous 1967 Soviet novel “The Life and Extraordinary Adventures of Private Ivan Chonkin” one of the main characters, Kuzma Gladishev, an autodidact, spends his life trying to graft a hybrid, that would have “potato tubers and tomato fruits”.
