The finalization of the sugarcane genetic map by Brazilian researchers this month will help Brazil maintain leadership in sugar production and export, say experts in the sector. Within five years plant scientists will develop varieties of sugarcane that are more productive, more resistant to cold, pests and disease, and also better at assimilating nutrients like phosphorous, says William Lee Burnquist, technology coordinator at Copersucar, a cooperative that is responsible for 20 percent of Brazil's sugar and alcohol production.

The sugarcane genome project, with 240 scientists participating, announced on Sep. 17 that 33,620 genes had been identified, of which 2,000 are related to sugar production.

Brazil produces some 23 million tons of sugar annually.
