Abstract

Conventional plant breeding is primarily basedon phenotypic selection of superior individuals amongsegregating progenies resulting from hybridization. It is oftentime consuming as breeding a new cultivar takes between eightand ten years and even then, the release of improved cultivaris not guaranteed. Hence, breeders are extremely interested innew technologies that could make this procedure moreefficient. Marker-assisted selection, often simply referred toas Marker-Assisted Selection (MAS) offers such a possibilityby adopting a wide range of novel approaches to improvingthe selection strategies in crop breeding. Molecular markersare powerful research tools that make it possible to determinethe genetic makeup of plants; for that it is possible the selectionby plants genotype. In this paper, we refer the significantadvancements towards application of molecular markertechnology for crop improvement in the last decade, in tomato.Finally, we discuss reasons why the greater adoption of MASin the future is inevitable, although the extent of its use willdepend on available resources, and may be delayed in less-developed countries.
