Agronomic evaluation of 'Bordô' grapevine (Ives) clones

Abstract

'Bordô' grapevines (Vitis labrusca) have great relevance to viticulture due to the quality they can impart to wines and juices. However, this cultivar has high variation in yield, ranging from 6 to 11 t ha ), the adoption of more productive clones can generate an increase in yield of around 38 %.

Productivity and quality of juices from different genotypes of ‘Bordô’ grape (Vitis labrusca) in the Vale do Rio do Peixe -SC region

“…However, it is worth noting that, among the 11 evaluated genotypes in the present study, the most productive were genotypes G13 with 38.2 t ha -1 (22.9 kg/ plant), G16 with 37.06 t ha -1 (22.2 kg/plant), G19 with 35.4 t ha -1 (21.1 kg/plant) and G08 with 34.7 t ha -1 (20.8 kg/ plant) p < 0.05 (Table 1). The cultivation of the same genotypes, evaluated in the present study, was also reported by Miotto et al (2014), where the G13 genotype proved to be the most productive (14.9 t ha -1 ) in Caldas-MG, in the south of Minas Gerais state, although the plants were conducted in a spreading system and were from the third to the fifth year of cultivation on average. High mean estimates, between 34.1 to 38.1 t ha -1 were also observed by Brighenti et al (2018), with genotypes G08, G16, G19 and G13 and proved to be the most productive, in the sixth year and in the same cultivation location.…”

“…High mean estimates, between 34.1 to 38.1 t ha -1 were also observed by Brighenti et al (2018), with genotypes G08, G16, G19 and G13 and proved to be the most productive, in the sixth year and in the same cultivation location. An important factor to be noted is that, among the most productive genotypes, in the present study as well as those reported by Miotto et al (2014) and Brighenti et al (2018), refer to the cultivars 'Paco' (G13) and 'Bocaina' Rev. Ceres, Viçosa, v. 68, n.4, p. 310-318, jul/aug, 2021 (G16).…”

“…The 'Bordô' cultivar is widely produced in Brazil, due to its rusticity and high color potential for the preparation of derivatives. However, this cultivar has cultivation restrictions in some regions due to Rev. Ceres, Viçosa, v. 68, n.4, p. 310-318, jul/aug, 2021 physiological disorders that can significantly reduce its production (Miotto et al, 2014;Castilhos et al, 2016). In the south and southeast regions, the maturation period of the 'Bordô' grape coincides with the rainy season and, in certain situations, the cultivar does not reach a satisfactory ratio of soluble solids and titratable acidity (SS/TA) to produce quality juices.…”

“…Brighenti et al (2018) state that an alternative to circumvent production problems is the use of genotypes that are better adapted to growing conditions and that increase and maintain constant productivity. Miotto et al, (2014) studied 12 different genotypes of 'Bordô' from a clonal selection program of the Minas Gerais Agricultural Research Institute (EPAMIG) in the municipality of Caldas-MG, with the objective of evaluating production and quality of fruits in subtropical wine-growing areas. The authors concluded that the genetic variability significantly influenced the productive behavior, and thus, indicated the 13-'Paco' genotype for being the most productive under the conditions studied.…”

Caracterização físico-química e sensorial de sucos da uva Isabel em cortes com diferentes variedades produzidas na região do Vale do Rio do Peixe-SC

“…No entanto, via de regra, a maturação da Bordô ocorre em períodos chuvosos nos estados do sul e sudeste brasileiro, prejudicando a qualidade das uvas, e por esta razão não atingem uma relação de açúcar e acidez suficiente para elaboração de um produto de qualidade, prejudicando por vezes o enquadramento do suco à legislação vigente (Chiarotti et al, 2011). Outro problema enfrentado em relação ao cultivo de Bordô é a oscilação na produção devido a distúrbios fisiológicos que prejudicam a do Rio do Peixe-SC Bender, A. et frutificação, reduzindo significativamente a produção em determinadas safras (Miotto et al, 2014;Castilhos et al, 2016).…”
