GRD resistance
A group of researchers has identified where within peanut’s genome the resistance to Groundnut Rosette Disease (GRD) lies, which will enable targeted plant breeding to give farmers a variety that can withstand the disease. By finding the major locus controlling GRD resistance and validating that locus as suitable for marker-assisted selection, the team achieved an historic accomplishment in 2021 in the fight against the most destructive peanut disease in Africa.
