Conteúdo: | 'Tommy Atkins' has general characteristics of tall trees, fruit with red blush skin and fair taste. It has reasonable anthracnose resistance, but is highly susceptible to mango malformation. Indian cultivars Amrapali and Mallika are small trees with sweet fruits, but their yellow skin color has low market acceptance. Due to their good characteristics for mango breeding, these cultivars have been used in hybridization but their general ability - GCA for fruit set is still unknow. To support future crosses, an experiment was carried out at Embrapa Cerrados, in Brasilia, to study fruit set success or compatibility among these three cultivars. A  completely randomized design with six treatments or corsses ('Mallika' x 'Tommy Atkins'; 'Tommy Atkins' x 'Mallika'; 'Mallika' x 'Amrapalli'; 'Amrapalli' x 'Mallika'; 'Tommy Atkins' x 'Amrapalli'; 'Amrapalli' x 'Tommy Atkins') and five replications (panicles) were used. Opened flowers were discarded from panicles, which were protected by perforated polyethylene bags. In the morning, young and still closed buds were removed, opened flowers were selected, emasculated and hand pollinated using anther of male progenior. The panicles were bagged and tagged. Fruit set was studied weekly for six weeks. 'Mallika' had the lowest compatibility, rate and 'Amrapalli' x 'Tommy Atkins' had the best fruit set with 16.1% success.
