Mango varieties have been evaluated in Brazil for only a few cycles of production. Therefore some mango varieties were evaluated under irrigation and for a longer period of production. Nineteen mango varieties were evaluated for eighteen years (1979 to 1998) at the Mandacaru Experimental Station, Juazeiro - BA. The plants were spaced 10 m x 10 m and the varieties were grafted on Espada. The average temperature (°C), rainfall (mm), relative humidity (%), evaporation (mm/d), sunshine hours (h/d) and solar radiation (h/d) during the experiment were recorded. Flowering dates for all varieties in each year as well as fruit yield were registered for the eighteen cycles of production without use of growth regulators. Some varieties started flowering after two years (Alphonso, Amarelinha, Bourbon, Brasil, Carlotão, Comprida Roxa, Florigon, Itiúba and Irwin) while Dusheri and Langra after nine and ten years, respectively. The varieties flowered from June to August, some of them presenting the typical pattern of alternate bearing (Maya, Haden, Itiúba, Bourbon, Irwin and Tommy Atkins). Some varieties presented an erratic pattern of production (Carlotão, Florigon, Kensington, Surpresa, Momi-k, Dusheri and Langra) while the other varieties were intermediate in production pattern (Alphonso, Amarelinha, Comprida Roxa, P. de Amoreira, Zill and Brasil). All can be recommended, except Langra and Dusheri, depending on the market preferences, since growth plant regulators are applied to give better uniformity in flowering and fruit production.
