Abstract
This chapter describes the demands of the trendy food industries from the agriculture and horticultural production sectors and the challenges faced by the breeders to meet out those demands. Though traditional methods of breeding has contributed a lot in evolving novel cultivars in several crop species, regular conventional breeding strategies takes long time to release a new desirable variety. Whereas recent developments in the genetic mapping and marker-assisted selection opened up new precise routes that shorten the time required to evolve an elite cultivar. Additional information on other advantages of using this molecular breeding approach are also outlined in this chapter in comparison with other modern breeding tools besides highlighting the scope of and need for MAS in the near future.
