Interpretive Summary: In this chapter, we update the information on the molecular markers, genetic linkage maps, and quantitative trait loci (QTL) of traits mapped to date. Information of the preview of genome sequences, which would be available in peanut populations for high resolution genetic and trait mapping such as multi-parent advanced generation intercross (MAGIC) and nested association mapping (NAM), is also discussed. The special emphases on Africa and China are given in different sections to update on the activities in peanut research and emerging issues. The goal of this chapter is to update the new progress in development of genetic and genomic resources and technologies in peanuts.

Technical Abstract: From lack of availability of molecular markers to the release of genome sequence of two of its diploid wild relative, the international peanut community has come a long way in the last decade, particularly during the last five years. However there still is long way to go when genomics-assisted breeding would be a routine implementation in crop improvement like in rice, maize and other crops. Nevertheless, the stage is now set to harvest the fruits of genomics research for peanut improvement. It is expected that with the increasing effort towards SNP based markers there will be an increased use of genomics-assisted breeding (GAB) in peanuts. It has been already proven to be efficient in developing high oleic, resistance to root-knot nematode and rust resistance in peanuts. Nevertheless, it will contribute to the peanut community in whole and global food supply and human health in general and to fight the malnutrition.
