“…Similarly, in some hot regions with higher temperature, grape phenological timing is accordingly advanced, which leads to a change of growing season in the time period (Jarvis et al, 2017). For example, in Xinjiang, Cabernet Sauvignon fully ripens in the middle of August (Zhang et al, 2019), thus the calculation of accumulated temperature from April to September may show an overestimation. Rather than a fixed time period, the climate conditions should be evaluated regularly, especially for some key pheno-phases.…”

The objective of this work was to estimate the influence of climate variability on viticultural zoning and variety regionalisation in China in the past 50 years. A multicriteria climatic indices system, which includes Frost-Free Season (FFS), Dryness Index (DI), and Extreme Low Temperature (ELT), was used to define climatic suitable areas and classify different climate zones for wine grape-growing in China. The Accumulated Effective Temperature (AET) was used as an index of variety regionalisation. Indices were calculated based on daily climatic observations from national ground weather stations throughout China from between 1967 and 2016. The variation trends were analysed by Sen’s slope and Mann-Kendall non-parametric tests in 13 representative wine growing sites. Based on the studied criteria, the suitable viticultural zone exhibited a continuous northward expansion with an average increase of 0.204 million km2/decade, largely due to increasing FFS. A significant increase of FFS was detected in most representative sites, with almost no detectable change of DI during the growing season. The analysis also revealed that the North East Region, Inner Mongolia Region, and Xinjiang Region are the three most profitable wine regions. Movement of the soil-burying line was limited to Shandong and Hebei provinces. Although the suitable viticultural zone increased, the data also revealed a decrease in the area for high quality wine production when considering varietal suitability. These results have important implications for understanding both new opportunities and challenges under changing climate and the latter’s effects on viticultural viability in China. They can also help guide stakeholders to develop adaptive strategies for maintaining the profitability of currently used regions and for developing new regions for viticulture.

“…The mass concentration of phenolic and coloring substances in the clones of Cabernet-Sauvignon, Merlot and Bastardo Magarachsky exceeded those of traditional varieties. In general, the value of these indicators of all studied wine materials corresponded to the values typical for the Western European ecological-geographical group [5][6][7][8][9][10][11][12][13][14][15]. Tasting assessments of the studied wine materials are presented in Figure 1.…”

The research has shown that clones of the Cabernet Sauvignon variety R-5 and R-8 are distinguished by higher rates of fruiting. The average bunch weight in clones reaches 188.7 ± 0.02 g (R-5) and 177.3 ± 2.6 g (R-8), exceeding the control. The yield per bush is on average 5.34 ± 0.21 kg and 4.25 ± 0.07 kg, exceeding the control by 1.54 - 1.23 times. Shoot productivity in terms of bunch wet weight in the Cabernet-Sauvignon R-5 clone is characterized as “high”. The clone of the Merlot R-3 variety has a high fruiting coefficient and a high fertility coefficient. The bunch weight of the clone reaches an average of 227.6 ± 4.3 g, the yield per bush is 6.3 ± 0.1 kg, exceeding the control. Shoot productivity in terms of bunch wet weight in the Merlot R-3 clone is characterized as “very high", in the control it is “high”. The clone of the variety Bastardo Magarachsky VCR-1 has a higher fruiting coefficient than in the control. The average weight of a bunch of a clone reaches 247.7 ± 1.4 g and exceeds the control (186.3 ± 9.14 g). The yield per bush is within 4.62 ± 0.2 kg, exceeding the standard variety by 0.85 kg. Shoot productivity in terms of bunch wet weight in Bastardo Magarachsky VCR-1 clone is characterized as “very high", in control this indicator is defined as “high”. The degree of variability of most traits in populations of standard varieties is characterized as average, which indicates the heterogeneity of the population and the possibility of further identification of new biotypes. According to the technological assessment, the indicators of wine materials in terms of physicochemical and organoleptic indicators, the introduced clones of the studied varieties were superior to the control varieties. In terms of the volume fraction of ethyl alcohol, mass concentration of volatile and titratable acids, all wine materials met the requirements of regulatory documents. Tasting scores of Cabernet Sauvignon wine materials were 7.7-7.9 points. The highest marks were obtained for the sample generated from clone R-8. Wine materials produced from the Merlot variety were noted as high quality, with pronounced varietal characteristics.

“…As regards acetates, the percentages shown by the hybrids were much higher than that seen in Monastrell, which had an average during the 3 years of 3% compared with the 26% for MC4, (close to that of Cabernet Sauvignon variety) and 14% for MS34. Zhang et al (37) reported that Cabernet-Sauvignon and Syrah exhibited a high level of acetylated and coumarylated anthocyanins, respectively, so it is possible that the most of our crosses have a pattern of acylation closer to Cabernet Sauvignon or Syrah varieties.…”

One way in which the wine sector is reacting to the challenge of climate change is to develop plant material that is adapted to the new conditions. Such a strategy will allow the continuation of quality viticulture in traditional winemaking areas that will otherwise be abandoned. The objective of this study was to characterize the anthocyanin composition and content of selected intraspecific hybrids of Monastrell with two other varieties (Syrah and Cabernet Sauvignon). The experiment was carried out over three successive seasons, and the polyphenolic quality of the grapes and wines was assessed along with the adaptation of the hybrids to the high temperatures which will inevitably affect our area (south-eastern Spain). The results showed that, compared with grapes of the Monastrell variety and the wines made from them, most of the hybrids (MS10, MS34, and MC111) had a higher total anthocyanin concentration and overall content of acylated anthocyanins, depending on the year studied.
