Abstract : In field trials in 1992 in Maracay, Venezuela, 4 commercial mango cultivars were grafted onto 6 polyembryonic and 3 monoembryonic rootstocks (selected for their short or medium height) and grown 6 m apart to give a density of 278 trees/ha. Four months later, trees were pruned to a height of 1.2 m and a canopy radius of 0.5 m. Evaluation after a further 15, 24 and 31 months showed no significant difference in canopy size developed on the different rootstocks. Yields (26.2 kg/tree) and productive efficiency by the growth cycle of 1995-96 were significantly lower in cv. Edward than in other cultivars whereas cv. Tommy Atkins gave significantly higher yields (64.1 kg/tree) and productive efficiency than either cv. Haden or cv. Springfels. The interaction between canopy and rootstock had no significant effect on productive efficiency.
