Patent Application
20200205329
This application claims the benefit of priority from EU Community Plant Variety Rights (CPVR) Application No. 20183517, filed Dec. 20, 2018.
Latin name of the genus and species of the plant claimed: Vitis vinifera L.
Variety denomination: ‘VOLTURNIS’.
The present application relates to a new and distinct variety of grape named ‘VOLTURNIS’. The new plant resulted from a planned hybridization program and is a selection from crossing 99-1-48 (unpatented) as the seed parent with Pinot Noir (unpatented) as the pollen parent in 2007. The resulting plant was selected in 2013 when growing in a cultivated area in Udine, Italy.
The ‘VOLTURNIS’ variety is distinguished from other grape varieties due to the following unique combination of characteristics: high vigour with semi-erect growth habit, low-medium blistering of upper side of leaf blade, circular shaped leaves, fruit cluster of medium or medium-large bunch density with 3-4 wings, medium harvesting time (early September in northeastern Italy), and resistance to downy mildew.
Asexual reproduction of this new variety by vegetative cuttings shows that the foregoing characteristics come true to form, are firmly fixed, and are established and transmitted through succeeding propagations.
Certain characteristics of this variety may change with changing environmental conditions (such as photoperiod, temperature, moisture, soil conditions, nutrient availability, or other factors). Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations (hue/value/chroma) are made with reference to The Royal Horticultural Society (R.H.S.) Colour Chart, 5th edition, London, England, 2007.
The color photographs shows typical specimens of this new variety and depict the color as nearly true as is reasonably possible to make the same in a color illustration of this character. It should be noted that colors may vary, for example due to lighting conditions at the time the photograph is taken. Therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from the photograph alone.
The new variety was identified due to its resistance to downy mildew and powdery mildew, and was suited to the climatic and soil conditions of central-northern Italy. The new variety can be used in wine production.
The following detailed description of the ‘VOLTURNIS’ variety is based on observations of asexually reproduced progeny. The observed progeny are plants which were 3-5 years of age. The following detailed description concerns the plants growing in an open field taken in Rauscedo, Italy in 2016-2018. The original plant and progeny have been observed growing in a cultivated area in Rauscedo, Italy, with medium texture soil that is rich in skeleton and alluvial in nature. Temperatures in Rauscedo, Italy range from a high of 29° C. to a low of −2° C. Average rainfall is 822 mm per year, with an average rainfall during the growing season (April-September) of 453 mm.
The chart used in the identification of colors described herein is The R.H.S. Colour Chart, 5th edition, except where general color terms of ordinary significance are used. The color values were determined in August-September 2018 under natural light conditions in Rauscedo, Italy.
