The objective of this study was to evaluate the influence of the canopy management for the formation of lateral shoots associated with density of canes on the yield and quality of grapes "Sugraone" in the São Francisco Valley. The experiment was carried out over two growing seasons (2011-2012) in a commercial vineyard of Sugraone in Petrolina, Pemambuco state, Brazil. The treatments consisted of two canopy managements (shoot topping associated to elimination of lateral shoots and shoot topping and formation of lateral shoots) combined with two to three densities of canes after pruning (1.8, 2.8 and 3.8 canes/rn/). The forrnation of "lateral shoots" increased yield and number of clusters per plant during two consecutive growing seasons, besides using 2.8 varas/nr' resulted in highest yields only in 2011 growing season. The variables mass bunch, mass berry, soluble solids (SS), soluble sugar, titratable acidity (TA) and pulp firmness were not affected by treatments, while the attributes related to color, as like brightness and hue angle ofthe skin, and total extractable polyphenols content were influenced by canopy management, especially in the 2012 growing season. Shoot topping to induce forrnation of laterais shoots associated with density of 2.8 canes/m" increased the yield of seedless grapes cultivar Sugraone grown in the São Francisco Valley, not significantly affecting the quality ofthe grape.  aSeedless varieties  aVitis  aUva  aViticultura  aUva de mesa  aUva sem semente  aVale do São Francisco1 aLIMA, M.
