- Pinot noir and Chardonnay are the two main varieties in Oregon. Together they comprise approximately 60% of the Oregon winegrape acreage, and 64% of the total production for a value of $10,482,000 (69%). Internationally, clonal selection of Pinot noir and Chardonnay have made available, for each variety, an array of clones with wide ranging levels of productivity and fruit quality. In the Champagne region, clones were selected for increased yields; in Burgundy, the main criterion was high fruit quality; and in Switzerland, the Pinot noir clone Mariafeld was selected for disease resistance. In the U.S., clones selected here and elsewhere continue to be evaluated for their suitability to local growing conditions. The Pinot noir clones included in the trial at Woodhall III Vineyard include representatives of diverse types loosely classified into four groups: 1) Pinot fin, typically characterized by having small clusters and prostrate growth habit; 2) Mariafeld, most noted for having loose clusters; 3) Upright, known for their erect growth habit; and 4) Fertile, typically having large clusters and prostrate growth habit (Price and Watson 1995). The Chardonnay clones at Woodhall III Vineyard, although not as numerous as clones in the Pinot noir trial, also represent a range of types with different levels of productivity and fruit quality. Vines in the Woodhall III Vineyard Pinot noir and Chardonnay clonal trials were in the eighth leaf in the 1996 season. Both trials consist of own rooted vines, planted on a 1.8 m x 2.7 m (6 ft x 9 ft) spacing, and trained to an upright vertical trellis. In 1996, yield components and juice composition were measured in both trials. Additionally in the Pinot noir clones, cluster architecture, fruit set, and vegetative growth parameters were measured. Results of skin extract analysis will be reported at a later date.
