Tomato (Solanum lycopersicum L.) is most important fruit vegetable grown worldwide for its high nutritive value. Traditional genetic markers and breeding methods have several defects that reduce the ability to estimate genetic diversity in plants as it highly dependent on the environment for expression. Among the available genetic rnarkers viz., morphological, cytological, biochemical and molecular (DNA), Molecular markers are an effective tool for efficient selection of desired agronomic traits because they are based on the plant genotypes and also are independent of environmental variations. Researchers have been calculated genetic variation in tomato landrace and cultivar collections using several molecular techniques including AFLP, RAPD, ISSR, SSR and SNP. An overview is conducted considering some useful above mentioned molecular markers to initiate systematic breeding programme on tomato improvement.
Genetic characterisation is first step of plant breeding for crop improvement.
Molecular markers have beenextensively used for genotyping andcharacterization of genotypes.
