02-07-2012 14:16 This is the VOA Special English Agriculture Report, from | http Scientists have made a genetic map of the tomato. Tomatoes are second only to potatoes as the world's most valuable vegetable crop. Eight years of work went into making the map, or genome. Three hundred scientists around the world took part in the project to sequence the tomato's DNA code. Giovanni Giuliano, a researcher in Italy, is part of the Tomato Genome Consortium. He says they started as ten countries and now have fourteen. Having the tomato's genetic map will help growers who are always trying to produce a better tomato. Mr. Giuliano says they now know not only what genes are there, but their order. Researchers published the genome of a tomato used by Heinz, the American food company famous for its tomato ketchup. Ketchup is a thick sauce used on hamburgers, hot dogs and other foods. Heinz's research manager, Rich Ozminkowski, says the company knows what it wants in a tomato. "Traits like sugars and, for Heinz, viscosity, or the juice thickness, and the redness of the tomatoes are all very critical traits for us," he says. Those are all controlled by a lot of different genes within the tomato. Mr. Ozminkowski says genome sequencing takes away much of the guesswork for breeders of tomatoes or other crops that have been mapped. In his words, "By having the genome information, we can pick out those tomato plants that have more of those genes." Until the late nineteen sixties, the ...
