Clone performance under different environmental conditions in California

Abstract

Clonal evaluation of winegrapes in California has not been extensive. Early selection work by Alley (1977), Olmo (unpublished data) and Goheen (personal communication) resulted in the current collection of virus-tested clones in Foundation Plant Materials Service (FPMS) at the University of California, Davis. However, release of these certified selections was generally not accompanied by publication of viticultural performance or wine sensory attributes. A present day effort to characterize differences among clones of several cultivars has begun (Wolpert et al, 1995), with the objective of determining the viticultural and enological characteristics of winegrape clones. Research to date has centered on certified selections of Cabernet Sauvignon, Chardonnay, Pinot noir (for sparkling wine) and Zinfandel. In this paper, Cabernet-Sauvignon and Chardonnay performance will be examined in greater detail.

Investigating kokumi flavour oligopeptides in wine

Kokumi is a complex sensation perceived as enhanced palatability. Under the influence of kokumi substances, foods/beverages tastes become more flavorful with increased intensity, spread, continuity, richness, harmony, and punch which are the six related characteristics corresponding to the Kokumi sensory concept [1].

Non-destructive his based analysis for shelf-life evaluation of table grape 

Fast, accurate, and non-destructive analytical techniques based on hyperspectral imaging (hsi) represent effective tools for food quality evaluation. A visible change in the appearance of a fresh product often negatively impacts the perceived quality from a consumer’s point of view.

USDA national grapevine germplasm resources: new curators, new directions

The National Plant Germplasm System (NPGS) in the United States Department of Agriculture safeguards numerous species. Grapevines are split in two locations: Davis, CA and Geneva, NY. The two germplasms maintain 43 Vitis species with over 4500 genetically unique accessions.

New varieties descendant from Monastrell with lower sugar and high phenolic content adapted to warm climates

Given that climate change is a continuous process, it is necessary to constantly search for new strategies that help the viticulturist sector to mitigate its consequences. All adaptation strategies will have a greater or lesser effect that in turn will be marked by the times of action. As a long-term action, a genetic breeding program to obtain new varieties descendant from Monastrell has been developed in the Region of Murcia (more specifically, in the IMIDA Research Center) since 1997. In this program, new red varieties have been developed through directed crosses of the Monastrell variety with other varieties such as Cabernet Sauvignon, Tempranillo and Syrah.
