'BRS MAGNA' - a novel grape cultivar for juice making, with wide climatic adaptation

Abstract

-'BRS

Yield and physicochemical characteristics of ‘BRS Magna’ and ‘Isabel Precoce’ grapes influenced by pruning in the São Francisco river valley

“…Therefore, pruning without selection of branches (P2) favored yield increases during the second growing season, as estimated for the 'Isabel Precoce' (46t/ha) and 'BRS Magna' (62t/ ha) cultivars. These values are considered very high yields as compared to those obtained with these same cultivars in other regions of the country, such as 25-30t/ha for 'BRS Magna', which is cultivated in the states of Rio Grande do Sul, São Paulo, and Mato Grosso (RITSCHEL et al, 2014), and 'Isabel Precoce' (CAMARGO et al, 2004).…”

“…However, a high number of bunches was observed in both cultivars in the second growing season, and significant differences between them were not found. The 'Isabel Precoce' and 'BRS Magna' cultivars are characterized by the high fertility of their buds, about 2.0 bunches per shoot (RITSCHEL et al, 2014), which explains the high number of bunches obtained in both cultivars, regardless of the type of pruning performed.…”

“…Juices of the 'BRS Magna' cultivar have an intense violet color and can be consumed pure or in cut with juices from other cultivars (RITSCHEL et al, 2014). This cultivar showed to be well suited to the tropical conditions of the São Francisco river valley, arousing a great interest mainly due to its high yield and grape quality.…”

Characterization of the aroma profile of novel Brazilian wines by solid-phase microextraction using polymeric ionic liquid sorbent coatings

“…It was also evaluated at Nova Mutum (MT) and Serra Gaúcha (RS, Brazil) presenting good agronomic and industrial performance. The full ripe 'BRS Magna' grapes exhibits a pleasant raspberry flavor, similarly to V. labrusca, and chemical traits such as 17-19°Brix sugar content, 90 meq L −1 average total acidity, and pH value of 3.60 [35]. The color of the juice and wine of 'BRS Magna' is intense violet.…”

“…The color of the juice and wine of 'BRS Magna' is intense violet. Since its inception, 'BRS Magna' has been used for grape juice making, improving the color, sweetness, and flavor of grape juices in Brazil [35]. However, to the best of our knowledge, there are no reports evaluating the aroma of 'BRS Magna' wines and comparison to the traditional 'Isabel' (or 'Isabella') wines.…”
