“…Monthly means and standard deviations for climatic elements: average (T Average ), maximum (T Max ), and minimum (T Min ) air temperature; global solar radiation (GSR); and rainfall depth (RD) from 2014 to 2018 in the Bebedouro Experimental Field, Petrolina, PE, Brazil. The number of bunches was high for most genotypes, with mean of 58 bunches per plant, confirming the high fertility of buds, which was a characteristic of the genotypes evaluated in this work (Leão et al 2017). The genotypes CNPUV 23, Marroo Seedless, and A Dona presented the highest number of bunches.…”

“…The genotypes CNPUV 23, Marroo Seedless, and A Dona presented the highest number of bunches. The commercial cultivars Thompson Seedless and Crimson Seedless presented the lowest number of bunches; these cultivars are characterized by low fertility of buds (Leão et al 2017), which is one of the factors that caused the substitution of these cultivars in the study region.…”

“…Seedless table grape cultivars from the Active Germplasm Bank of the Embrapa Semiarid were selected by their production potential and high fertilities of buds (Leão et al 2017), such as ' A Dona' , developed by the Agronomic Institute of Campinas; 'BRS Linda' (Camargo et al 2003a), 'BRS Clara' (Camargo et al 2003b), and other advanced cultivars improved by the Embrapa Grape and Wine; and the 'Marroo Seedless' , developed by the CSIRO in Australia; 'Romana' or ' A 1105' , selected by the University of Arkansas, USA; and ' Arizul' ('CG 351'), developed by the INTA in Argentina. Preliminary works showed the desirable characteristics of 'Marroo Seedless' in the São Francisco Valley (Leão 2002).…”

The São Francisco Valley is the main producing region of table grape in Brazil. The objective of this work was to evaluate the agronomic performance and physicochemical characteristics of 14 seedless table grape genotypes to select those with potential to be used in commercial crops in the São Francisco Valley, Brazil, or as parents in breeding programs. The experiment was carried out over five crop seasons (2014 to 2018), in Petrolina, PE, Brazil. The treatments consisted of 14 seedless table grape genotypes. The results showed significant effects for all variables evaluated. The highest estimated yield per production cycle were found for 'Marroo Seedless' (26.5 t•ha-1), 'BRS Linda' (26.4 t•ha-1), 'CNPUV 23' (24.9 t•ha-1), 'A1105' (24.3 t•ha-1), and 'A Dona' (20.2 t•ha-1). Soluble solid (SS) content varied from 13.35 ºBrix ('CNPUV 23') to 21.63 ºBrix ('A Dona'). The titratable acidity (TA) of the genotypes varied from 0.27 g•100 mL-1 ('CNPUV 23') to 0.72 g•100 mL-1 ('Crimson Seedless'). Principal component analysis showed that the first three principal components explained 81.9% of the data variance, and grouped the best genotypes for production components and fruit chemical composition on different sides of the X-axis. These results allowed the identification of a group of seedless grape cultivars that can be used for commercial crops or as parents for controlled crossings in a local table grape breeding program.

“…The variations observed in production and number of bunches among production cycles may be the consequence of inter and intra-annual climate variations observed over the study (Figure 1), which may affect floral and bud fertility differentiation, causing common variations in production in consecutive crop seasons (Leão et al, 2017).…”

Rootstocks for the new seedless table grape ‘BRS Vitória’ under tropical semi-arid conditions of São Francisco Valley

‘BRS Vitoria’ is the most important Brazilian table grape cultivar in the domestic and foreign markets, standing out for the seedleness, pleasant flavor, high yield and mildew resistance. The aim of the present study was to determine the effect of the rootstock on the yield, production components, vigor, and physical and chemical characteristics of the ‘BRS Vitória’ grape under irrigation in the Brazilian semi-arid region. The experiment was conducted over eight consecutive production cycles in the period from 2015 to 2018 in a commercial area in the Senador Nilo Coelho project, Petrolina, PE. The treatments were represented by seven rootstocks: ‘IAC 572’, ‘IAC 766’, ‘IAC 313’, ‘Harmony’, ‘SO4’, ‘Paulsen 1103’, and ‘Freedom’, using a randomized block experimental design with four replications. The results were variable among production cycles, with significant effects of the rootstock in some cycles and/or in the overall mean of the cycles. The variables of pruning weight, sprouting, bud fertility, and titratable acidity were not affected by the rootstock in any of the production cycles evaluated in this study. ‘Harmony’ rootstock promoted greater berry mass and diameter but reduced the soluble solids content. Vines of ‘BRS Vitória’ showed moderate vigor, high bud fertility and yield, satisfactory characteristics of bunch and berry, sugars and acids content that meet the requirements of the most demanding markets in all the rootstocks evaluated in this study.

“…This training system also increased the bud fertility index, independent of the period of the year, which reached values of 0.90 and 0.99 bunches per shoot, under the lyre and the espalier system, respectively, during the harvest of the first semester, and 0.74 and 0.80 bunches per shoot for the harvest in the second semester. The bud fertility of 'Chenin Blanc' was high when compared with the average bud fertility of 0.64 bunches per shoot for eleven different table grapes evaluated in the same region (Leão et al, 2017). Table 1 shows the influence of the rootstock on the pruning mass in the harvests of the first and second semesters, highlighting the rootstock IAC 572 as being more vigorous, with significant differences for 'SO4' in the first semester harvest and for 'Paulsen 1103' in the second semester.…”

The aim of this research was to study the influence of training system and rootstock on the yield, vigor and physiology of the 'Chenin Blanc' grapevine at São Francisco Valley, northeastern Brazil. An experiment was carried out on eight harvests, from 2013 to 2017, in Petrolina, in the state of Pernambuco. Grapevines were grown under two training systems, lyre and espalier, and five rootstocks: 'IAC 572', 'IAC 313', 'IAC 766', 'Paulsen 1103' and 'SO4', using a split-plot randomized block design, with training systems assigned to the main plot and the rootstock assigned to the subplot. Lyre favored an increase in the number of bunches, branches and leaf mass in the harvest of the first semester of the year, while in the second semester there were increases of 40 % in the number of bunches and 10 % in leaf mass. Lyre promoted more balanced vines, showing a better ratio between production and pruning weight (Ravaz index). The rootstocks 'IAC 766', 'IAC 313' and 'IAC 572' increased yield and bunch mass under both training systems, while 'SO4' reduced yield and vigor. The stomatal conductance and instantaneous efficiency of water use were not influenced by either the training system or the rootstock. Under tropical conditions in the São Francisco Valley, 'Chenin Blanc' grapevine may be grown under the lyre training system, preferably on the 'IAC 766' rootstock, to obtain high yields and balanced grapevines.
