Interpretive Summary: Mango has been considered to be difficult plant species to improve in breeding programmes because of certain inherent characteristics including: (i) a long juvenile phase; (ii) a high level of heterozygosity resulting in unpredictable outcomes in hybridization; (iii) only one seed per fruit, (iv) heavy fruit drop leading to low retention of crossed fruits; (v) polyembryony in many cultivars; and (vi) the large area require for a meaningful assessment of hybrids. Despite these drawbacks, mango breeding can be successful because of its wide range of genetic variation and the ease with a selected hybrid can be vegetatively propagated. Barring a few hybrid varieties resulting from planned by hybridization programmes, which are now gaining increased attention, almost all known cultivars have resulted from the selection of change seedlings from natural cross-pollinations. This chapter describes the latest information of classical breeding and genetics. It outlines general objectives for mango breeding and methods of breeding that have been successfully used in the past and new molecular techniques that will be useful in the future.
