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.

Nitrogen forms and Iron deficiency: how do Grapevine rootstocks responses change?

Grapevine rootstocks provide protection against environmental biotic and abiotic stresses. Nitrogen (N) and iron (Fe) are growth-limiting factors in many crop plants due to their effects on the chlorophyll and photosynthetic characteristics. Iron nutrition of plants can be significantly affected by different nitrogen forms through altering the uptake ratio of cations and anions, and changing rhizosphere pH. The aim of this study was to investigate the response mechanisms of grapevine rootstocks due to the interaction between different nitrogen forms and iron uptake.

NEW INSIGHTS INTO VOLATILE SULPHUR COMPOUNDS SCALPING ON MICROAGGLOMERATED WINE CLOSURES

The evolution of wine during bottle ageing has been of great interest to ensure consistent quality over time. While the role of wine closures on the amount of oxygen is well-known [1], closures could also play other roles such as the scalping phenomenon of flavour compounds. Flavour scalping has been described as the sorption of flavour compounds by the packaging material, which could result in losses of flavour intensity. It has been reported in the literature that volatile sulphur compounds (VSC) can be scalped on wine closures depending on the type of closure (traditional and agglomerated cork, screw-cap, synthetic [2]).

Valorisation agroviticole de l’effet terroir par l’enherbement des sols

The studies developed by INRA and UV, in Angers, concern wine-growing areas and their optimized management, both from an agro-viticultural and oenological point of view. Previous work (Morlat, 1989) made it possible to give a scientific dimension to the concept of viticultural terroir and demonstrated the considerable influence of this production factor on the quality and typicity of wines (Asselin et al, 1992 ) . A methodology for the integrated characterization of terroirs, based on the “Basic Terroir Natural Unit” (considered as the smallest spatial unit of territory usable in practice, and in which the response of the vine is homogeneous), has been development (Riou et al , 1995).
