Drought tolerance difficult but not impossible goal for marker assisted peanut breeding


As the Peanut Foundation works through a five-year, $6 million research project designed to improve peanut production efficiency, scientist will direct initial efforts to identifying cultivars with disease resistance, pest resistance and characteristics such as improved nutrition. But finding varieties with increased tolerance to drought may be possible, says Howard Valentine, Foundation executive director. But that chore, he says, will be much more difficult. Traits such as disease resistance will involve something like five or ten genes. Drought tolerance, he says, may include 50. He discussed the possibilities at the recent Southern Peanut Growers Conference in Panama City, Fla.
