Abstract

Abstract: The objective of this work was to characterize the productive and qualitative performances of 11 clones of 'Bordô' grape (Vitis labrusca) destined to wine and juice production, in the region of Vale do Rio do Peixe, in the state of Santa Catarina, Brazil. The experiment was carried out in the 2011, 2012, 2014, and 2015 crop seasons. The analyzed yield components were: number of clusters per vine, yield, cluster weight, accumulated yield, and alternate bearing index. The analyzed morphological characteristics of clusters were: number of berries per cluster, berry diameter, cluster compactness index, and cluster length. In order to assess grape quality, the following parameters were analyzed: soluble solids (SS), pH, titratable acidity (TA), SS/TA ratio, total anthocyanins, and total polyphenols. The 'Bordô' grape clones 13 and 16 ('Paco' and 'Bocaina') are the most suitable ones for cultivation in the wine producing region of Vale do Rio do Peixe, as they show the highest yields, production stability, and grapes with adequate quality for wine and juice elaboration.

Highlights

In the state of Santa Catarina, Brazil, viticulture is an important economic activity
The grapes are mainly used for wine and juice elaboration, with a small percentage destined for fresh consumption (Back et al, 2013), and the main cultivars produced in the region are the American ones and hybrids, among which are 'Isabel', 'Niagara', and 'Bordô'
The clones were obtained from the clonal selection of 'Bordô' grape in the Empresa de Pesquisa Agropecuária de Minas Gerais (Epamig) vineyards, and in private properties in the municipality of Caldas, MG, Brazil (22°55'S, 46°23'W)

Summary

Introduction

In the state of Santa Catarina, Brazil, viticulture is an important economic activity. The planted area with grapevines is of 5,060 ha, and the production is about 66,000 tons of grapes. The region of Vale do Rio do Peixe, in the middle west of the state, is the most traditional producing region, responsible for more than two-thirds of grape production in the state. The main producing municipalities are Tangará, Videira, Pinheiro Preto, and Caçador. The grapes are mainly used for wine and juice elaboration, with a small percentage destined for fresh consumption (Back et al, 2013), and the main cultivars produced in the region are the American ones and hybrids, among which are 'Isabel', 'Niagara', and 'Bordô'. 'Bordô' ( known as 'Ives') is one of the main American cultivars produced in Brazil, standing out for its high rusticity due to resistance to fungal
