Groundnut is an important nutrient-dense crop grown in over 100 countries. Breeding for improved varieties is critical for increasing yields and enhancing quality. This chapter describes the genetic resources of groundnut and their potential for mining desirable traits, potential breeding targets and ways to maximise groundnut oil quantity and quality. The chapter provides a detailed case study of groundnut production in Uganda, and outlines the potential benefits of improved groundnut varieties, including disease resistance, as well as suggesting future directions for groundnut research.
