Abstract : The effects of the polyembryonic mango rootstocks Rosa, Camphor, Ceniap 2, Perú and Pico 'e loro, and the monoembryonic rootstocks Divine, Tetenené Manzana and Currucai on the size and shape of fruits of Haden, Tommy Atkins, Edward and Springfels mangoes were investigated in Venezuela. These rootstocks were selected because of their medium-small growth habit. Haden fruits were largest on Perú, Ceniap 2 and Pico 'e loro, and smallest on Tetenené Manzana. Fruits from Edward grafted onto the different rootstocks were similar in shape to those from the controls (rootstock Hilacha). Fruits from Springfels grafted onto Pico 'e loro, Rosa, Perú, Tetenené Manzana and Ceniap 2 were larger and heavier than those from controls. Fruits from Tommy Atkins grafted onto Tetenené Manzana, Currucai, Rosa, Divine and Camphor weighed more than the controls, and size and shape of fruits were very variable. Fruits from Tommy Atkins and the rootstock Tetenené Manzana were round with a large beak, those from rootstocks Ceniap 32, Rosa and Pico 'e loro were oblong with a prominent beak, and those from Camphor were oblong with a slight beak. The differences in fruit size and shape on the different rootstocks were more pronounced in the cultivars Haden and Tommy Atkins.
