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 Early selection work by Alley (1977), Olmo (unpublished data) and Goheen (personal communication) resulted in the current collection of virus-tested clones in Foundation Plant Materials Service (FPMS) at the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.

“Zonation”: interpretation and estimation of “Great zonation” (GZ) following the base methodology of “GRANDE FILIERA” (GF) (Great chain)

Dans des travaux précédents sur le zonage, on a traité de la « Grande Filière », du « terroir », du « territoire », de la «″Terra »″ (« Terre »”), des « Petits zonages ou sub-zonages », du « Grand Zonage », de la qualité (nous en avons classifié plus de quatre-vingt-dix), des « Grands Objectifs » (GO) de l’activité vitivinicole et des moyens utilisés pour les atteindre. Dans le « GRAND ZONAGE » (GZ) nous avons précisé que pour zoner, nous partons des aspects

Applications pratiques du zonage vitivinicole

Le zonage vitivinicole présente toute une série d’applications pratiques. Son importance est en train d’augmenter, soit en fonction des moyens techniques chaque fois plus performants, qui rendent possible le développement des zonages de plus en plus intégrées, consistants et utiles, soit en fonction d’un marché de plus en plus mondialisé. L’article situe la contribution du zonage au niveau de la production vitivinicole et du développement du territoire.
