Abstract

Mango (Mangifera indica) is regarded among the five most important fruit commodities traded worldwide, along with bananas, apples, grapes and oranges, with over 40M tonnes produced annually worldwide. The genus Mangifera is believed to contain up to 70 species, with origins in the North‐Eastern Indian subcontinent and South East Asia. Despite this, there is a relatively poor understanding of the pedigree, genetic relatedness and the history of domestication of many M. indica cultivars and related species worldwide. The development of molecular tools for mango is extremely limited, thus its genes, genetics and genomics remain largely unidentified. Whole genome sequencing and the development of genetic maps of these species are important components in marker assisted breeding and genetic improvement. An international genomics program is being undertaken to build these genetic resources including the development of large numbers of single nucleotide polymorphism (SNP) molecular genetic markers, the development of a genetic map for mango, association of phenotypic traits to the genetic map to identify useful individual markers for breeding, assessment of the genetic diversity in mango germplasm collections, and sequencing, assembly and annotation of the mango genome. These genetic resources will facilitate identification of genetic components with useful agronomic traits for breeding material. The goal of whole genome sequencing of mango is accelerated progress in the breeding of mango cultivars with improved agronomic traits (eg reduced vigour, disease resistance, fruit colour) that could not be accomplished by traditional methods.
