This is one of 280 summaries describing key outputs from the projects
run by DFID's 10-year Renewable Natural Resources Research Strategy
Principally based on Projects R6627, R7460, R7257, R8247 and R8425.
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.
