Impact of the ‘Pinot’-family on early ripening in cool climate viticulture varieties

Abstract

‘Pinot Precoce Noir’ (PPN) is an early ripening clone of ‘Pinot Noir’ (PN). The phenological differentiation is visible by an about two weeks earlier onset of veraison. It was found that the early veraison locus Ver1 on chromosome 16, previously identified in ‘Calardis Musqué’, originated from PPN. A highly correlated SSR marker, namely GF16-Ver1,was developed and tested for its ability to molecularly differentiate between PPN and PN as well as its potential to trace individual descendants. GF16-Ver1 shows a 2bp difference in fragment size, which is sufficiently descriptive to discriminate between the original PN allele and the mutant Ver1 allele of PPN associated to early veraison. All screened cultivars showing the specific fragment sizes of the veraison affecting PN or PPN allele, appeared to be related to the Pinot family, demonstrating its unique character. Grouping of cultivars based on the fragment length of GF16-Ver1 matched with known pedigrees and allowed a reliable allocation of entire family trees to their respective PN or PPN founder. Additionally, grouping of cultivars by the GF16-Ver1 marker demonstrated the phenological significance and descriptive value. The marker enables an easy screening of genetic resources and breeding material using established SSR-based marker-assisted selection pipelines. The use of GF16-Ver1 will help breeders to adapt their breeding programs for cool-climate viticulture to the challenges of climate change through counter-selection of Ver1. It will also help to elucidate all early ripening PPN descendants on a genetic basis and demonstrate the high relevance of this locus in current cool-climate varieties.

Weather classification over the Western Cape (February, 1996 – 2000) and viticultural implications in the Stellenbosch wine district

Une étude préliminaire des situations météorologiques journalières a été réalisée pour l’Afrique du Sud et pour les mois de février (période de maturation des raisins dans la Province occidentale du Cap), à l’image de la classification synoptique réalisée aux latitudes tempérées en France (Jones & Davis, 2000), afin d’étudier les relations entre le climat et la viticulture à des latitudes plus basses.

On the stability of spectral features of four vine varieties in Brazil, Chile and France

Satellite images of vineyards in France, Chile, and Brazil are used to study spectral differences between the vine varieties Cabernet Sauvignon, Merlot, Pinot Noir, and Chardonnay, to verify if features of a given variety are conserved at vineyards in completely different terroirs.

The effects of cover cropping systems on vine physiology, berry and wine quality in a climate change scenario in Switzerland

Sustainable weed control with little detrimental effects on vine physiology, yield, berry quality, soil structure, health and biodiversity is a key factor in vineyard management. Few options are available to avoid herbicide utilization and minimize negative effects of frequent tillage on soil quality. The present project aims to investigate and develop different cover management strategies in a cool climate viticultural region in Switzerland. The impact of different treatments on vine, must and wine has been studied in an experimental vineyard in Changins, Switzerland for one year and will be continued over the next three years.

Actual challenges and the need to produce alternative products from red grapes rich in phenols and antioxidants

The global consumption of wine has undergone significant changes after several years of covid-19, which was the beginning of a global crisis of the current century. This pushed some people to start looking for comfort and security as they felt that the world around them was losing these benefits. In most cases, this has led to them to idea of rethinking their lives in an attempt to live better or continuing to stay true to their habits and lifestyles despite the pressure of changes. Alcohol in any form is a part of these reactions, leading to increased consumption in the early stages of a crisis, particularly in relation to anxiety.

Effect of bleaching with different agents on protein hydrolysate characteristics

High temperatures can reduce the phenolic content of grapes, especially anthocyanins and copigments involved in colour stabilisation of red wines [1]. This could make it difficult to maintain stable colour during storage [2].
