A preferência do consumidor brasileiro pela uva Niágara Rosada, cultivada no centro-sul do país, se manteve estável no período compreendido entre 2007 e 2016. Dentre as uvas tradicionais com sementes destacam-se, as uvas do grupo Itália, cultivadas no centro-sul e também em clima tropical semiárido. Entretanto, a opção do consumidor nacional por uvas com sementes vem diminuindo, e as apirênicas, cuja produção era totalmente destinada à exportação, passaram a ocupar posição importante no mercado doméstico. Este movimento, somado ao elevado custo de produção do cultivo de uvas finas tradicionais sem sementes (Thompson, Crimson e Superior) na região tropical de clima semiárido tem resultado na busca por novas cultivares. Assim, na última década, diversos genótipos desenvolvidos por empresas internacionais têm sido introduzidos na região e testados, juntamente com as cultivares “BRS”, desenvolvidas pela Embrapa. O menor custo dos “royalties” pagos pelo uso das cultivares nacionais, associado à maior fertilidade de gemas, ao manejo simplificado de cachos, à possibilidade de realização de duas safras por ano e à tolerância ao míldio e às chuvas, têm estimulado a expansão do cultivo de BRS Núbia (com sementes), BRS Isis e BRS Vitória, que já apresenta uma área plantada no semiárido estimada em 1.500 ha. The Brazilian table grapes chain is diversified, in relation both to the climatic conditions of the production regions and to the cultivar matrix, which includes American grapes and European and hybrid grapevines, with and without seeds. The Brazilian consumer preference for the Niágara Rosada grape, grown in the center-south of the country, remained stable in the period from 2007 and 2016. Among the traditional grapes with seeds are the Italy group grapes, grown in the center-south and also in semi-arid tropical climate. However, the national consumer's choice for grapes with seeds has been decreasing, and the seedless grapes, whose production was once wholly destined for export, came to occupy a vital position also in the domestic market. This movement, coupled with the high cost of production of traditional seedless grapes (Thompson, Crimson and Superior) in the tropical semi-arid region has resulted in the search for new cultivars. Thus, in the last decade, several genotypes developed by international companies have been introduced in the area and tested, along with "BRS" cultivars, developed by Embrapa. The lower cost of the royalties paid for the use of the national varieties, associated with the higher fertility of buds, the simplified management of bunches, the possibility of two harvests per year and the tolerance to mildew and rainfall, have stimulated the expansion of cultivation of BRS Nubia (with seeds), BRS Isis and BRS Vitória, which already has a planted area in the semiarid region estimated as 1,500 ha. ven., 31 août 2018 16:50:34 +0200 jeu., 19 déc. 2024 09:17:54 +0100 http://preo.ube.fr/territoiresduvin/index.php?id=1546 http://preo.ube.fr/territoiresduvin/index.php?id=1872 La chaîne du raisin de table brésilien est diversifiée. Elle est fonction des conditions climatiques des régions de production et de l'origine des variétés que ce soit des raisins américains et des cépages fins ou des hybrides de type fin, avec et sans pépins. La préférence du consommateur brésilien pour le raisin Niagara Rose, cultivé dans le centre-sud du pays, est restée constante entre 2007 et 2016. Parmi les raisins traditionnels à pépins, se distingue le groupe italien, cultivé dans le centre-sud et également dans les climats tropicaux semi-arides. Cependant, l'apétence du consommateur national pour les raisins avec pépins a diminué, et les raisins apyréniques, dont la production était totalement destinée à l'exportation, ont fini par occuper une place importante sur le marché intérieur. Ce mouvement, ainsi que le coût de production élevé de la culture de raisins fins traditionnels sans pépins (Thompson, Crimson et Superior) dans le climat tropical semi-aride, a entraîné la recherche de nouveaux cultivars. Ainsi, au cours de la dernière décennie, plusieurs génotypes développés par des sociétés internationales ont été introduits dans la région et testés, ainsi que les cultivars « BRS » développés par l'Embrapa. Le coût moins élevé des redevances versées pour l'utilisation des cultivars nationaux, associé à une plus grande fertilité des bourgeons, à une gestion simplifiée des grappes, à la possibilité de deux récoltes par an et à la tolérance au mildiou et à la pluie, a stimulé l'expansion de la culture de la BRS Nubia (avec pépins), de la BRS Isis et de la BRS Vitoria, dont la superficie cultivée en climat semi-aride est déjà estimée à 1 500 ha.
