Patent Application
20230200271
Genus and species: Vitis vinifera L.
Variety denomination: ‘TRASEMIS’.
This application claims the benefit of priority from QZ Community Plant Variety Office (CTVO) Application No. 20213392, filed Dec. 21. 2021.
The present application relates to a new and distinct variety of grapevine named ‘TRASEMIS’. Our new plant resulted from a planned hybridization program and is a selection from crossing ‘SK-00-1/10’ (unpatented) as the seed parent with ‘TRAMINER’(unpatented) as the pollen parent in 2009. The resulting plant was selected in 2017 when growing in a cultivated area in Udine, Italy.
The ‘TRASEMIS’ variety is distinguished from other grapevine varieties due to the following unique combination of characteristics: leaf blistering, length of teeth, blade size, bunch length, area of anthocyanin coloration of main veins on upper side of blade of mature leaf, goffering of blade of mature leaf, resistance to downy and powdery mildew and winterhardiness. ‘TRASEMIS’ is distinguished from the male parent ‘TRAMINER’ as described in Table 1.
‘TRASEMIS’ is distinguished from the female parent ‘SK-00-1/10’ as described in Table 2.
Of the many commercial cultivars known to the present inventors, the most similar to the new grapevine ‘TRASEMIS’ is ‘TRAMINER’, to which a comparison has been provided above.
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. The cuttings are grafted onto K5BB rootstock clone VCR 102. The new variety was asexually reproduced in Rauscedo (PN), Italy.
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, 6th edition, London, England, 2019.
The color photographs show typical specimens of the 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 photographs alone.
The following detailed description of the ‘TRASEMIS’ variety is based on observations of asexually reproduced progeny. The observed progeny are plants that were 2-4 years of age. The following detailed description concerns plants growing in an open field in Rauscedo (PN), Italy in 2019-2021. The original plant and progeny have been observed growing in a cultivated area in Rauscedo (PN), 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, 6th edition, except where general color terms of ordinary significance are used. The color values were determined in August-September, 2021 under natural light conditions in Rauscedo (PN), Italy.
