Abstract : The selection of rootstocks for dwarfness has been an important aspect of the mango breeding programme in the central region of Brazil. Although mango cultivars Tommy Atkins and Haden are productive with tasty and fibreless fruits, their trees are vigorous and very tall, which makes it difficult to apply cultural practices and difficult to harvest. A field experiment was conducted in Distrito Federal, Brazil, to study the effect of scion and rootstock cultivars on the growth, yield and fruit quality of mango. Mango cultivars Tommy Atkins, Haden, Winter and Van Dyke were used as scion cultivars, while Mallika, Amrapali, Santa Alexandrina, Extrema, Imperial, Maçã, Comum and Rosinha were used as rootstocks. Amrapali (monoembryonic) reduced tree height by 70 cm, regardless of the scion cultivar. The yield of Tommy Atkins (7.77 t/ha) was much higher when Rosinha was used as rootstock.
