Through genotyping and a genome-wide association study, researchers from the US and China uncovered genetic markers associated with desired agronomic traits in sugarcane. As they report in PLOS One, the researchers evaluated more than two dozen agronomic traits within a panel of 236 elite sugarcane germplasms from 12 countries to uncover three amplified fragment length polymorphism markers significantly associated with aerial root, laminal color, and fiber content.
