“…Field studies on the performance of fungus resistant varieties are scarce in the literature [46][47][48][49][50] and, as noted above, the resistance of PIWI cultivars varies not only with genetics but also with location [10], so comparisons should be taken with caution. For instance, one of the most comprehensive studies was the one by Zamboni et al [51], who evaluated the adaptability of 26 resistant varieties in terms of yield, quality and resistance against fungal diseases to Emilia-Romagna hills (Ravenna, Italy) over a 5-year period (1994-1998).…”

The vine is highly susceptible to numerous fungal diseases, the incidence and severity of which are increasing because of climate change. To fight them, large amounts of phytosanitary products are generally used, although they entail important economic and environmental costs. The new fungus resistant vine varieties (PIWI) constitute one of the most active lines of research on plant material in viticulture and are regarded as a viable solution to respond to the requirements of European Directive 2009/128/EC. In the present work, the evolution and impact of the three main fungal diseases (powdery mildew, downy mildew and botrytis bunch rot) were monitored in plots in the Somontano region (Huesca, Spain), comparing three PIWI varieties (Sauvignon Kretos, Souvignier gris and Muscaris) with a susceptible control variety (Sauvignon blanc) in real field growing conditions over three successive years (2016–2018). The main ampelographic characters of each variety were studied and a weekly follow-up was carried out to track the development of each disease, relating it to climatic variables. Regardless of the climatic conditions (one of the growing seasons was rainy and the other two corresponded to dry years, with differences in the distribution of rainfall), the three PIWI varieties hardly presented any symptoms, demonstrating a high resistance to downy mildew and powdery mildew and even to botrytis. Principal component analysis results pointed to a differential behavior versus the control and treated Sauvignon blanc plants in terms of disease resistance. Based on production results, despite the youth of the plantation, the excellent potential of Sauvignon Kretos variety was observed. However, from the analysis of the quality of wine obtained in microvinifications from these fungus resistant varieties in the second and third year, the one obtained from Muscaris seemed to have the best organoleptic properties. Apart from environmental considerations, given that these fungus resistant varieties can significantly contribute to the sustainability of wineries, they may also respond to the demand of consumers who want zero-pesticide products or of the supporters of ecological products adjusted to European regulations.

“…planta -1 ), medidas preventivas de controle devem ser adotadas para controlar a alta intensidade de antracnose (WURZ et al 2017). Bonin et al (2017) verificaram que cultivares PIWI como Cabernet Cortis, Regent e Bronner, que apresentam resistência genética ao míldio, não apresentam resistência à antracnose. Neste caso, o míldio tende a ocupar o lugar de uma doença de importância secundária e, portanto, a antracnose poderá tornar-se uma doença de importância primária.…”

O livro, com 21 capítulos reunindo inúmeros autores de renomada experiência, traz uma infinidade de informações, fruto de extensas revisões e principalmente obtidas através de densos projetos de pesquisa desenvolvidos pelas principais instituições públicas, capitaneada pela UDESC, em parceria com produtores individuais ou associados, localizados na Região de Altitude mais tradicional na produção de uvas de Santa Catarina. A identificação das melhores cultivares e as possíveis combinações de porta-enxertos, a definição do manejo do dossel, a carga de gemas, o manejo da poda e os sistemas de condução para cada situação, aliados a todas as questões relativas ao manejo o solo, da nutrição e adubação e a delicada e complexa questão da fitossanidade, chegando na colheita e processamento, entre outros, exemplifica a importância de todos capítulos desse grande livro.

“…Regarding to downy mildew resistance, Zanghelini et al (2018) indicated that cultivars 'Calardis Blanc', 'Felicia' e 'Helios', had a partial resistance to downy mildew in the climatic conditions of Santa Catarina State. Bonin et al (2017) observed that PIWI cultivars 'Bronner', 'Cabernet Cortis' and 'Regent' showed little resistance to Anthracnose. And finally, De Bem et al ( 2020) in a study carried out in the region of Trento, in northern Italy, found that the white PIWI varieties Muscaris and Jasmine showed a high degree of resistance to downy mildew, while Bronner, Pӧlӧskei Muscotály and Solaris showed intermediate resistance and Bianca presented the highest susceptibility to downy mildew.…”

“…One of the advantages of these varieties is the reduction of the number of pesticide applications (FULLER et al 2014), especially in warm humid areas such as southern Brazil. The use of PIWI cultivars can be considered an option for Brazilian growers, as a way to reduce the use of pesticides, consequently reducing costs and improving grape quality (DE BEM et al, 2016;BONIN et al, 2017). Also, more recent wine tastings have shown that it is possible to make wine from these varieties with a quality similar to that of traditional varieties (BASLER;PFENNINGER, 2003).…”

Downy mildew (Plamopora viticola) is one of the major problems to produce wine grapes in Brazil, a main cause of yield losses in the Southern region of the country. An alternative to the use of pesticides is the use of resistant varieties (PIWI): wine grapes combining high oenological potential and resistance to diseases. The goal of this work was to assess the vegetative and productive performance and maturation of three PIWI varieties (‘Felicia’, ‘Calardis Blanc’ and ‘Helios’) produced at altitudes of 840m and 1250m in the 2020, 2021 and 2022 vintages. The study is focused on four phenological stages: budbreak (BBCH 7), full bloom (BBCH 65), veraison (BBCH 81) and maturity/harvest (BBCH 89). The criteria for measuring the productive performance were, the number of clusters, average cluster weight, production per plant, yield and Ravaz index. As parameters for technological and phenolic maturation, pH, soluble solids, total acidity and total polyphenols were evaluated. The budbreak occurred at the end of August until the second fortnight of September, the flowering occurred in the second week of October, the veraison occurred during the month of December, and the maturity/harvest occurred from the second fortnight of January until the beginning of February. The earliest budbreak occurred with ‘Felicia’ in the vineyard at 1250m and the latest occurred with ‘Calardis Blanc’. Regardless of the vineyard altitude, there was practically no difference in the flowering date between varieties and the vineyards altitude, the veraison and the maturity/harvest occurred earlier in the vineyard at 840m. The varieties produced at 840 m had a shorter cycle and proved to be more productive when compared to those produced at 1250 m. The studied varieties showed good phenological adaptation, high yield and maturation indices suitable for the production of quality still and sparkling white wines at both altitudes. From the results obtained, ‘Felicia’ and ‘Calardis Blanc’ seem to be the most promising varieties for cultivation in both altitude ranges.
