A wild tomato species from the Galapagos Islands has been discovered by scientists from Wageningen University & Research to be resistant to a wide range of pest insects. This species is closely related to the cultivated tomato, making the resilience easier to interbreed into the latter and ultimately making it resistant to many different types of insects.\n<\/div>\n
Cultivated tomatoes are far more vulnerable to pests and diseases than some of their wild relatives. The process of breeding modern tomatoes has resulted in the loss of a lot of their natural resistance, while wild species have remained much better at coping with insects.\n<\/div>\n
Scientists have been working to reverse this by reintroducing resistance from wild tomato species via breeding. The problem is that most of these plants are very distant relatives of the cultivated tomato and scientists have yet to successfully interbreed the required traits. The wild tomato from the Galapagos Islands, however, is genetically very similar to the cultivated tomato. Moreover, its resistance is coded within a single chromosome, which should make cross-breeding into existing plants much easier.\n<\/div>\n

Multi-resistant<\/strong><\/h4>\n
\u201cWe have been busy with this research since 2010,\u201d said Ben Vosman, scientist at Wageningen University and Research. \u201cWe worked with samples of the wild tomato species Solanum galapagense<\/em> from a gene bank. The first discovery was that this tomato species is resistant to whiteflies. Then it turned out that it is actually resilient to a lot of other insects too, including the green peach aphid and caterpillars of the beet armyworm. That was a very pleasant surprise.\u201d\n<\/div>\n

Less pesticide benefits the environment<\/strong><\/h4>\n
Cultivated tomatoes are easily affected by pest insects. One is the whitefly, which transmits viruses that infect the plants and eventually kill them. This fly is normally combatted by pesticides. \u201cIf we can make cultivated tomatoes resistant to whiteflies, this will directly benefit the environment,\u201d Vosman states.<\/div>\n
<\/div>\n
While this problem is still relatively manageable in greenhouses, for example through integrated control, there are pests there too. In field crops, the problems with insects are much bigger. \u201cWe expect most of the gain to be in field cultivation and in the tropics,\u201d Vosman continues. \u201cWe are delighted with this discovery.\u201d<\/div>\n
