Scientists at Texas AgriLife Research said they have identified a genetic marker that could help them develop a high-biomass sorghum for biofuel production. The nonflowering sorghum could grow up to 20 feet tall and contain as much as three times the amount of biomass of conventional varieties, the researchers said. "When cellulosic-ethanol conversion facilities become widespread, this feedstock would allow a producer to produce a grain, fiber or high-biomass crop," one of the researchers said.
