Three new varieties of tomato that are resistant to Tomato leaf curl virus (ToLCV) are boosting Indian farmers’ profits up to ten times over and are capturing much commercial interest. Previously, the disease could cause farmers to lose their whole crop, and infection spread rapidly, as the virus is carried by whiteflies. Now, the new varieties ‘Sankranthi’, ‘Nandi’ and ‘Vybhav’ give very high yields and don’t need to be sprayed with insecticide. Sixteen seed companies have already used the new varieties to produce hybrid tomatoes – which are being grown by an estimated 55,000 farmers in southern India alone. Seed of the three varieties has reached more than 14 institutes in 13 different countries, and there is continuing global demand, which is being met mainly through the World Vegetable Center.
