Molecular Mapping and Breeding in Mango

The Mango (Mangifera indica L.) is a member of family Anacardiaceae. It is one of the most important tropical fruit crops in the world. Most of the cultivars grown commercially are selections rather than introducing by breeding programs. Although, traditional breeding techniques cannot fulfill the demand of improved cultivars to promote superior quality traits due to many constraints like long juvenile phase, high heterozygosity, alternate bearing, polyembryony, heavy fruitlet drop, etc. Further, there is lack of understanding in heritability of the most important horticulture traits in mango. Therefore, by linking the important traits with molecular characteristics will help to improve the efficiency of mango breeding programs. The genetic markers and location in the genome that associated with important traits are commonly identified by utilizing genetic map. Consequence in an improvement of strong association between traits and molecular marker in marker-assisted selection. With the help of genetic map, mango breeders can easily identify the potential parents and progeny at early stage. Therefore, in this chapter, we have summarized the linkage and genetic map generated by mango researchers using various molecular markers, represented all 20 linkage groups that could be utilized as valuable tool and database by mango breeders for trait-specific breeding.
