“…The Submédio São Francisco Valley, located in a semiarid region of Brazil, is the main producer of seedless table grapes in the tropical axis. However, despite the increase and the economic importance of cultivars introduced in the region, the susceptibility to diseases and lack of adaptation to environmental conditions of some old and traditional cultivars have increased the demand for new seedless table grape cultivars adapted to the environmental conditions in semiarid regions of Brazil (Leão, 2021).…”

The absence of seeds has been one of the most valued traits in grapes (Vitis spp.) for fresh consumption. However, the simultaneous selection of superior genotypes for multiple traits is complex. The objective of this study was to select genotypes of superior seedless table grapes in semiarid regions of Brazil. Multiple traits were considered by using the factor analysis and genotype–ideotype best linear unbiased prediction (FAI‐BLUP) selection index. A total of 110 grape progenies from 24 crosses were evaluated for traits of agronomic interest. Each hybrid was represented by a single vine plant, without experimental design or repetition. The mixed‐model methodology was used to predict the breeding values. The FAI‐BLUP index was used to select superior genotypes based on factor analysis and the genotype–ideotype distance. Four factors explained the 11 characteristics studied, with a variability of 81.84%. Desirable gains were observed for 10 of the 11 traits evaluated. The FAI‐BLUP index allowed the selection of superior seedless table grape hybrids, which can be used in the genetic improvement of grapevines. In conclusion, we report the selection of seedless table grape hybrids for our study to advance in the table grape breeding program in Brazilian semiarid regions.

“…'BRS Tainá' is the first Embrapa grape cultivar fully developed in semi-arid tropical environmental conditions, recommended for the Submedium of São Francisco Valley. It is a white seedless grape with medium size berries, firm pulp texture and pleasant neutral taste (LEÃO et al, 2021). 'BRS Tainá' vine is a hybrid resulting from the crossing between the apyreneous cultivars Sugraone (♀) and Marroo Seedless (♂), obtained by the imma-ture embryo rescue technique (LEÃO et al, 2020a).…”

‘BRS Tainá’ is a new seedless table grape cultivar developed and recommended for the Submedium of São Francisco Valley, the main producing and exporting region of table grapes in Brazil. The objective of this study was to evaluate the influence of rootstock on vigor, bud fertility, sucrose and total soluble carbohydrates content in leaves of ‘BRS Tainá’ vine cultivated in semi-arid environmental conditions in the Brazilian Northeast. The treatments were represented by eight rootstocks: ‘101-14 MgT’, ‘IAC 313’, ‘IAC 572’, ‘IAC 766’, ‘Paulsen 1103’, ‘Ramsey’, ‘SO4’ and ‘Teleki 5C’. The experimental design was in randomized blocks with four replications, in split plots, the production cycles were considered as plots, and eight rootstocks as subplots. The following variables were evaluated: pruning weight, stem diameter, number of lateral bunches, bud fertility, sucrose and total soluble carbohydrates content in leaves. The ‘BRS Tainá’ vine had moderate canopy vigor and 54% of bud fertility. The carbohydrate content and sucrose in the leaves did not differ among treatments during pruning. Therefore, it is possible that there is no effect of the rootstock on the initial vegetative growth of ‘BRS Tainá’ vines, which vigor and bud fertility remained stable in the initial production cycles.

In viticulture, choosing the most suitable rootstock for a specific scion cultivar is an efficient and cost-effective way to increase yield and enhance the physicochemical characteristics of the fruit. The objective of this study was to evaluate the agronomic performance of the ‘BRS Tainá’ grapevine on different rootstocks under the conditions of the Sub-Middle São Francisco Valley. The main experimental factor consisted of eight rootstocks (IAC 313, IAC 572, IAC 766, 101-14 MgT, Paulsen 1103, Ramsey, SO4, and Teleki 5C), arranged in randomized blocks with four replicates. The experiment was conducted over four production cycles, from 2021 to 2023, in a commercial crop area in Petrolina, PE, Brazil. There were significant effects of rootstocks for the yield and number of bunches per plant, as well as berry length and firmness. ‘BRS Tainá’ achieved the highest yield (22.2 kg per plant) when grafted onto the Paulsen 1103 rootstock, which was superior to the yield on 101-14 MgT, IAC 313, and IAC 572 rootstocks. The highest number of bunches (88) was obtained with ‘BRS Tainá’ grafted on Paulsen 1103, while the lowest number (63) was obtained on IAC 572; both these rootstocks were not significantly different from the other rootstocks. For all scion–rootstock combinations, the mean values for soluble solid (SS) content, titratable acidity (TA), and the SS/TA ratio were similar to those previously described for ‘BRS Tainá’, meeting the commercialization standard. The results for the yield and number of bunches per plant indicate the suitability of grafting ‘BRS Tainá’ on Paulsen 1103 under the semi-arid tropical conditions of the São Francisco Valley.
