Abstract

Marker-assisted selection (MAS) in peanut has lagged behind other major crops. This is due in good part to the genetic bottleneck that occurred at tetraploidization, resulting in a limited amount of molecular variability detectable among accessions of the cultivated species. However, marker maps have been developed from wild species, and, to an increasing extent, the cultivated species using new marker types. It is expected that, with the increase in number of simple sequence repeat (SSR) markers and development of single nucleotide polymorphism (SNP)-based markers, there will be greater use of MAS in both interspecific and cultivated accession crosses. MAS has already proven itself to be useful in developing cultivars possessing resistance to the root-knot nematode, and is being used for selection for resistance to late leaf spot and rust, as well as for the high-oleic-acid trait.
