Plant biotechnology has great potential for improving target traits in crops. This can be achieved by the production of transgenic crops and marker-assisted breeding. Marker-assisted breeding has gained momentum in recent times since it does not need biosafety regulations. Several kind of molecular markers are available for use in crop breeding, such as restriction fragment length polymorphism, microsatellites, sequence characterized amplified region, sequence-tagged site, inter-simple sequence repeat amplification, amplified fragment length polymorphism and single nucleotide polymorphism. Sequence-related amplified polymorphism is a novel molecular marker system which is based on open reading frames (ORFs) developed from genome sequence data of Arabidopsis. It provides a unique combination of forward and reverse primers which can be selected arbitrarily giving a large number of primer combinations. Since this is an ORF-based marker system, it targets functional genes and has potential for their application in crop breeding. This marker system was first used and demonstrated by Li and Quiros in Brassica oleracea in 2001, and since then there have been several reports in different plant species ranging from field crops to tree species for assessing genetic diversity, mapping and tagging of genes, hybrid identification and sex determination. This review provides an overview of SRAP markers and their applications in crop improvement
