Marker-assisted recurrent selection (MARS) is helping maize breeders develop higher yielding and drought-tolerant improved varieties faster than ever before, according to a recent study from scientists at the International Maize and Wheat Improvement Center(CIMMYT).

“With conventional breeding, it often takes up to 7-8 years for varieties to reach farmers,” said Yoseph Beyene, a CIMMYT maize breeder working with the CGIAR Research Program on Maize (MAIZE) and one of the authors of the study. “With MARS, those varieties take only 5 years to reach farmers, and display greater genetic gain, even under drought conditions”
