“…Mean soluble solids content of the 'BRS Ísis' grapes was 16.41 °Brix, which is in agreement with the soluble solids contents found by Leão et al (2016) and Ritschel et al (2015), but these contents were higher than the values of about 14 °Brix obtained by Ahmed et al (2019) for the cultivar BRS Ísis in a subtropical region of the South of Brazil.…”

“…The clusters of the cultivar BRS Ísis had mean weight of 337 g, with significant differences among production cycles. The highest values were obtained in the second semester 2018, when the clusters achieved a mean value of 410 g, which was near the values of mean cluster weight reported by Ritschel et al (2015) and Leão et al (2016) for this same cultivar. The rootstock Paulsen 1103 favored clusters with greater weight than the rootstock Freedom, but this response was observed only in the first semester 2017, while in the mean of the production cycles, clusters of greater weight were found on 'IAC 313' compared to the rootstock Harmony, and differences were not found between these and the other rootstocks.…”

“…The high yield capacity of this cultivar, which remained stable over three consecutive production cycles in 2017 and 2018, is noteworthy (Table 3). The mean yield of the six production cycles was estimated at 39 ton/ha/cycle, greater than that reported for this cultivar by Leão et al (2016) and Ritschel et al (2015), representing an increase of 68 % in relation to mean annual yield of 25 ton/ha/year in this region (Leao et al, 2018). High yield and bud fertility are prominent advantages of this new seedless grape cultivar, drawing the interest of growers and, consequently, rapidly increasing the area in which it is grown in this region.…”

“…The total amount of vines were 42 per replication (7 rootstocks x 6 vines) which corresponds to 168 vines in each season. Fruits was harvested when in full maturity, with adequate soluble solids content and titratable acidity according to the characteristics of the cultivar BRS Ísis in the Vale do São Francisco (Leão et al, 2016).…”

“…The cultivar BRS Isis, released in 2013, is characterized as a red table grape with traces of seeds, elongated berries, medium size, and firm and crisp texture. Its grapevines have high vigor and tolerance to downy mildew (Plasmopora vitícola), high bud fertility, and yields greater than 30 ton/ha/cycle in the Vale do São Francisco (Leão et al, 2016). This cultivar is adapted to a production system with two harvests per year under the subtropical conditions of Brazil, recommending crop load management for a density of 5 cluster/m 2 , aiming to ensure stable production in the two harvests (Ahmed et al, 2019).…”

The seedless table grape 'BRS Melodia' stands out for its pink color and the special flavor of red berries, which make for commercial classification as gourmet type grapes. Cultivation of this new table grape cultivar is expanding in the São Francisco Valley, in the Brazilian Northeast region. The aim of this study was to determine the effect of the rootstock on vigor, on yield components, and on physicochemical characteristics of 'BRS Melodia' grapes grown under the semi-arid tropical conditions of the São Francisco Valley. The experiment was carried out under irrigated cultivation in a commercial area in the municipality of Casa Nova, Bahia, Brazil, from 2021 to 2023.Treatments consisted of the rootstocks 101-14 MgT, IAC 313, IAC 572, IAC 766, Paulsen 1103, Ramsey, SO4, and Teleki 5C in a randomized block experimental design with four replications. There was no effect of the rootstock on the following variables: branch and leaf fresh matter, sprouting percentage, total soluble solids content (SS), titratable acidity (TA), and SS/TA ratio. 'BRS Melodia' grapevines had high vigor regardless of the rootstock used. The Ramsey rootstock led to reduced bud fertility compared to IAC 572 and IAC 766. As the vines advanced in age, the rootstocks IAC 572 and IAC 766 provided the highest yields and number of clusters per vine. The physicochemical characteristics of the 'BRS Melodia' grapes meet the standards required for commercialization on all the rootstocks used.

Brazil has emerged as a significant producer of seedless grapes due to high consumer demand. This has led to increased production of seedless grapes in non-traditional cultivation regions, such as subtropical areas. To meet this demand, the search for new grape varieties suitable for these conditions, such as the ‘BRS Isis’ variety, has become an option for growers. The interaction between grape cultivars and rootstocks is specific, and their adaptability to climatic conditions can result in uneven performance. Therefore, the choice of rootstock should be considered before making any recommendations. The purpose of this study was to assess the productive performance, physical-chemical, and biochemical properties of the ‘BRS Isis’ vine grafted onto rootstocks (‘IAC 572’, ‘IAC 766’, and ‘Paulsen 1103’) in two production cycles. The experimental design consisted of randomized blocks, with seven blocks and three plants per plot, for a total of 63 vines. Thus, the vine’s income components, physical qualities of bunches and berries, chemical profile, bioactive substances, and antioxidant activity were assessed. The Tukey test (5% probability) was used to compare means between rootstocks. The data on scion cultivar and rootstock pairings were further evaluated using principal component analysis (PCA). There were substantial variations in the rootstocks, with ‘IAC 572’ and ‘IAC 766’ producing more bunches, generating more fresh mass, and having a longer bunch length than ‘Paulsen 1103’. However, phenolic compounds and flavonoids were greater in ‘BRS Isis’ grapes than in ‘Paulsen 1103’. ‘BRS Isis’ shows good adaptation to subtropical environments when employing the IAC 572 and IAC 766 rootstocks due to their higher yield and bioactive component accumulation compared to grapes grafted onto ‘Paulsen 1103’. However, regardless of the rootstock utilized, ‘BRS Isis’ grapes perform well commercially in subtropical environments.
