In: Stalker, H.T., Wilson, R.F. (editors). Peanuts: Genetics, Processing, and Utilization. Academic Press and AOCS Press. pp. 111-145.

Interpretive Summary: Most previous advances in peanut cultivar development have been made using conventional breeding methods for self-pollinated crops. Peanut has lagged behind many other crops on use of molecular genetic technology for cultivar development in part due to lack of investment, but also because of low levels of molecular polymorphism within A. hypogaea. Recently, there have been many advances in genomics research on peanut, and those advances are beginning to affect cultivar development. These advances in technology have enabled the identification of molecular markers associated with QTLs for several economically significant traits. MAS is becoming more common in peanut cultivar development programs, and several cultivar releases are anticipated in the near future. Technological advances should also enable progress in the near intractable problems of drought tolerance and resistance to aflatoxin contamination.
