CARVALHO, Cássia Regina Limonta et al. Evaluation of mango cultivars selected by "Instituto Agronômico de Campinas" compaired to others of commercial importance. Rev. Bras. Frutic. [online]. 2004, vol.26, n.2, pp. 264-271. ISSN 0100-2945. http://dx.doi.org/10.1590/S0100-29452004000200021.
Two new mango cultivars, IAC 103 Espada Vermelha and IAC 109 Votupa, resistant to the mango wilt caused by the fungus Ceratocystis fimbriata and selected by the "Instituto Agronômico de Campinas" (IAC), were compaired to four Floridian cultivars used for commercial production in the State of São Paulo: Tommy Atkins, Van Dyke, Palmer and IAC Haden 2H. This last one is a clone selected from the Haden 2H cultivar. The yield capacity of the cultivars was evaluated in a field experiment with six cultivars, five replications and three plants per plot, using a completely randomized blocks design, in Votuporanga, State of São Paulo. The yield, resistance to diseases and fruit-fly as well as physical and chemical parameters of the fruits were evaluated. The cultivar Palmer was the most productive, with good adaptation to the local soil and climatic conditions. 'Haden 2H' was the most susceptible cultivar. There was no cultivar resistant to all diseases and 'Espada Vermelha' showed some resistance to fruit-fly. The proportion of peel, pulp and seeds of the fruits were evaluated. The cultivar Votupa showed the highest percentage of pulp, which was similar to the commercial cultivars Van Dyke, Tommy Atkins and Palmer. To evaluate the nutritive value of the cultivars, the chemical composition of the fruits were made in "Instituto Agronômico de Campinas" and "Instituto de Tecnologia de Alimentos", both located in Campinas, State of São Paulo. The fruits were analysed for pH, soluble solids (ºBrix), total acidity, lipids, total protein, residual fixed minerals (ash), pectin, ascorbic acid, total carotene, total alimentary fibers, total carbohidrates and calories, and the content of calcium, cupper, iron, phosphorus, magnesium, manganese, potassium and zinc. The cultivar "Espada Vermelha" differed from the others by the chemical parameters, mainly in the mineral composition and in the content of total carotenoids and lipids, which provided intense flavor and coloration to its fruits. 'Votupa', 'Palmer' and 'Van Dyke' presented higher acidity and caloric fruits, whereas 'Espada Vermelha', 'Tommy Atykns' and 'Haden 2H' had fruits less caloric and with lower acidity.
