Abstract
Abstract The production of mandarins is incipient in Northeastern Brazil in spite of the large regional market. Few studies have reported the performance of mandarins under the tropical conditions in Brazil, considering that, in general, the quality and yield of these fruits are more expressive in regions of subtropical and Mediterranean climates. In this work, tree size, fruit production and quality of four mandarin hybrids (‘Piemonte’ mandarin-tangor, ‘Murcott’ tangor and ‘Page’ and ‘Nova’ tangelo-mandarin) grafted on ‘Rangpur’ lime rootstock in Umbaúba, State of Sergipe, Brazil, were evaluated. The experimental design was randomized blocks with three replicates and three trees per plot. Planting was carried out in 2008 at tree spacing of 6.0 x 3.0 m in rainfed cultivation system. ‘Piemonte’ mandarin-tangor was more productive than ‘Murcott’ tangor and ‘Nova’ and ‘Page’ tangelo-mandarin, under the conditions evaluated in Umbaúba up to the eleventh year after planting. Regarding fruit quality, ‘Piemonte’ mandarin-tangor and ‘Page’ tangelo-mandarin can be indicated both for fresh consumption and for processing due to their higher total soluble solids, ratio and vitamin C content in relation to ‘Murcott’ tangor.
Highlights
Brazil is the world’s fifth largest mandarin producer, and in 2018, produced 996,872 tons in cultivated area of 5 2,767 hectares (FAO, 2018)
Brazilian tangerine production is mainly directed to the fresh domestic market (BASTIANEL et al, 2014)
Mandarin hybrids showed significant differences in most variables evaluated, with coefficients of variation (CV) less than 20% (Tables 1 to 4). This CV range is reported for studies of variety selection in citrus breeding using similar biometric variables (PIO et al, 2006; MOURÃO FILHO et al, 2007; BASSAL, 2009; BASTIANEL et al, 2014)
Summary
Brazil is the world’s fifth largest mandarin producer, and in 2018, produced 996,872 tons in cultivated area of 5 2,767 hectares (FAO, 2018). The state of São Paulo is the largest producer, with 384,714 tons in cultivated area of 1 0,819 hectares, followed by Minas Gerais, Paraná and Rio Grande do Sul, all of them with production above 100 thousand tons (IBGE, 2018). In 2018, the production of mandarin in Bahia was 8,755 tons in cultivated area of 1,007 ha, while in Sergipe, 3,356 tons were produced in 480 ha. Paraíba has the largest mandarin production in the region, 13,257 tons in a cultivated area of 1,845 ha (IBGE, 2018). In all these states, orchards are concentrated in the Coastal Tablelands, a region with low rainfall and cohesive soils with low water retention (SOUZA et al, 2008). The regional consumer market is expressive, requiring research on varieties that suit the growing environment in this region and, contribute to the diversification of crops and increase producers’ income (ALMEIDA; PASSOS, 2011)
