Abstract : Selection of rootstocks for dwarfness has been an important aspect of the mango breeding programme at Central Region of Brazil. Although 'Tommy Atkins' and 'Haden' mangoes are products with tasteful and fibreless fruits, their trees are vigorous and very tall, which make cultural practices and harvest difficult. To determine the effect of different rootstocks on growth, yield and fruit quality of mango cultivars, 8 rootstocks were used as whole plots and 4 scion cultivars as subplots. '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. The rootstock 'Amrapali' (monoembryonic) reduced tree height in 70 cm, regardless of the scion cultivar, and the yield of 'Tommy Atkins' (7.77 t/ha) was much higher when 'Rosinha' was used as rootstock. 'Winter' and 'Van Dyke' had high quality fruits, regardless of the rootstock used.
