Online published on 21 February, 2022. Abstract Tomato (Solanum lycopersicum L) is an important vegetable crop under family Solanaceae. It is a diploid plant having chromosome number 2n=2x=24. In tomato breeding great advances are achievable due to the possibility of hybridization within and among species in a controlled manner, the variability present in the species, the presence of self-pollination which further leads to the recessive mutation expression and the lack of gene duplication. In tomato, fruit yield, quality and resistance to pests and diseases are the general breeding goals. For improvement of the qualitative traits by gene transfer from wild species to the cultivated ones, tomatoes are believed to be a classical example. The achievements in breeding of tomato are based on traditional breeding-genetic methods till now. Also a change in the introduced cultivars possessing useful and desired traits, is not exploited yet. For enhancing the productivity in future, it is believed that conventional breeding would not help out. Different techniques are established using molecular genetics and molecular markers for significant progress. So altogether, the valuable tools for tomato breeding might be the combined application of traditional breeding and plant biotechnology including selection based on molecular markers and marker-assisted selection.
