First insights on the intra-species diversity in V. berlandieri: environmental adaptation and agronomic performances when used as rootstock

Abstract

Context and purpose of the study – In grafted plants, such as grapevine, increasing the diversity of rootstocks available to growers is an ideal strategy to get adaptation to climate change. The rootstocks used for grapevine are hybrids of various American Vitis, including V. berlandieri. The rootstocks currently used in vineyards are derived from breeding programs involving very small numbers of parental individuals.

Material and method – In 2005, 78 wild female V. berlandieri plants were ampelographically identified in Texas, USA. The coordinates and elevation of each sampling site were recorded. After growing the plants in field, we selected 286 genotypes. A genotyping by sequencing allowed us to extract 104,378 SNP and to explore the genetic structure of the V. berlandieri population. After grafting, 846 plants were grown in pots and evaluated for root-related traits for two independent years. In our experimental design, four rootstocks (110R, 5BB, SO4, and Börner) widely used in vineyards were added to the study population in order to evaluate the agronomical performances of V. berlandieri wild rootstocks.

Results – Two subpopulations were highlighted and related with variations in elevation, temperature and rainfall of sampling locations. A genome-environment association study highlighted 18 genetic markers associated with environmental variations. Root-related traits have shown a moderate variability (coefficient of variation from 0.15 to 0.45). Two genotypes were detected for their root-related traits performances when compared with commercial rootstocks. Moreover, 8 genetic markers were associated with four root related traits (the root average diameter, the number of small roots, the number of medium roots, and the total number of roots).

Our results shed new light on rootstock genetics and could open up possibilities for introducing greater diversity into genetic improvement programs for grapevine rootstocks in order to adapt grapevine facing climate change.

Effects of grapevine leafroll associated virus 2 infection on leaf net photosynthesis, yield and berry quality in Vitis vinifera cv. Malbec

Grapevine leafroll associated virus 2 (GLRaV-2) is one of the most common damaging viral diseases in vines, causing significant reductions in photosynthesis, yield and grape quality. In this study, we tested the hypothesis that the leaf net photosynthesis and the transport of sugars to the berries is progressively reduced along the season in vines infected with GLRaV-2, and consequently, the yield (kg per plant) and total soluble solids (TSS) at the berry harvest-ripe stage are lower than non-infected vines.

Influence of genotype and water availability on respiratory costs and plant carbon balance in grapevines (Vitis vinifera L.)

Due to the important contribution of agriculture to the global carbon dioxide (CO2) balance, new techniques are currently being developed to accurately estimate the carbon balance of different crops. Field studies to date in grapevines have been based on carbon allocation and biomass accumulation dynamics.

Phenological behavior and evolution of maturation of grapes of juice preparation

The ripening level of the grape is one of the most important factors in the quality of its derivatives, because of the complex phenomena inherently related to the varieties and environmental conditions. The objective of the present study was to monitor the phenological development of the Chardonnay variety and to evaluate the influence of the different ripening points on the production of juices.
