Sustainable groundnut production can be realised through development and adoption of high yielding cultivars possessing durable rust resistance. Integrating conventional breeding with genomic tools in identifying candidate rust resistance genes, and introgressing the genes into adapted elite germplasm, with the aid of molecular makers, could enhance breeding for rust resistance. This review highlights breeding approaches for groundnut rust resistance, with emphasis on integrating conventional breeding with marker-assisted selection. The life cycle, symptoms and epidemiology of the pathogen are also discussed to understand the host-pathogen interaction and guide groundnut rust resistance breeding.
