Abstract
A new and distinct variety of grapevine plant named `FLEURTAI`,
primarily adapted to the growing conditions of the temperate
regions and characterized by its strong vigor; erect growth habit;
small to medium circular shaped leaves with medium texture; medium
sized berry clusters with golden-green berries that have an amber
nuance on the sunny side of the berry, soft flesh, neutral taste,
and no flesh coloration primarily used for wine; early harvesting

Claims
What is claimed is:
1. A new and distinct grapevine, referred to as `FLEURTAI`, as
herein described and illustrated by the characteristics set forth
above.
Description
Latin name of the genus and species of the plant claimed:
Vitis.times.vinifera (hybrid).
Variety name: `FLEURTAI`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct summer/fall
bearing grapevine variety, botanically known as Vitis vinifera, and
hereinafter referred to by the name `FLEURTAI`.
The new grapevine `FLEURTAI` is a product of a controlled breeding
program conducted by the inventors in Udine, Italy. The objective
of the breeding program was to develop a new grapevine variety
particularly characterized by resistance to cold (<-20.degree.
C.), resistance to downy mildew (Plasmopara viticola), and
tolerance to powdery mildew (Uncinula necator).
The new grapevine `FLEURTAI` originated from a cross made by the
inventors in Udine, Italy. The female or seed parent is the
grapevine variety, Vitis vinifera cv. `Tocai Friulano`
(unpatented), and the male or pollen parent is the grapevine
variety, Vitis cv. `20/3` (Bianca.times.SK77-4/5) (unpatented).
The new grapevine `FLEURTAI` was discovered and selected by the
inventors as a single flowering plant within the progeny of the
stated cross in a controlled environment in 2002 in Udine, Italy.
Asexual reproduction of the new grapevine variety by grafting was
first performed in February 2004 in Rauscedo, Friuli Venezia Giulia
region, Italy, and has demonstrated that the combination of
characteristics as herein disclosed for the new cultivar are firmly
fixed and retained through successive generations of asexual
reproduction. The new cultivar reproduces true to type.
SUMMARY OF THE INVENTION
`FLEURTAI` is primarily adapted to the climate and growing
conditions of the temperate regions with average yearly temperature
about 13.degree. C., minimum winter temperature about -20.degree.
C., annual rainfall around 700-1500 mm of rain (e.g. North-Eastern
Italy, Friuli). This region provides the necessary year-round
temperatures required for it to produce and maintain a strong
vigorous plant with consistent fruit production from April through
November on primocanes and in the ensuing year from April through
November on the floricanes.
The following traits have been repeatedly observed and are
determined to be unique characteristics of `FLEURTAI`, which in
combination distinguish this grapevine plant as a new and distinct
variety. 1. Strong vigor; 2. Erect growth habit; 3. Small to medium
circular shaped leaves with medium to dark green upper surfaces and
light green lower surfaces and medium texture; 4. Medium size,
loose to medium dense, conical berry clusters with two middle size
wings; golden-green color berries with amber nuances on the sunny
side of the berry, soft flesh, neutral taste, no flesh coloration;
primarily for wine; maturing in late August (Middle Friuli,
North-Eastern Italy); 5. Primocanes and floricanes with oblate
cross section, brownish color, no lenticels, and short-middle
internodes (diameter: 8 mm); 6. Late August harvesting time (Middle
Friuli, North-Eastern Italy); and 7. Resistance to winter
temperature (-23.degree. C.), resistance to downy mildew, and
tolerance to powdery mildew.
Plants of the new grapevine `FLEURTAI` differ from plants of the
parents, Vitis vinifera `Tocai Friulano` (unpatented) and Vitis
cross `20/3` (unpatented), in the following characteristics
described in Table 1.

Of the many commercial cultivars known to the present inventor, the
most similar to the new grapevine `FLEURTAI` is the female parent
`Tocai Friulano`, to which a comparison has been provided

BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of
the new grapevine `FLEURTAI` showing the colors as true as is

DETAILED BOTANICAL DESCRIPTION
The following description of `FLEURTAI` unless otherwise noted, is
based on observations taken during the 2011, 2012, and 2013 growing
seasons(s) in Udine, Italy and Fossalon di Grado (GO), Italy, from
plants dug from a nursery located in Vivai Cooperativi Rauscedo,
Rauscedo (PN), Italy during the beginning of December 2007 and
planted approximately 16 to 20 weeks later in Udine, Italy and
Fossalon di Grado (GO), Italy. The phenotypical descriptions and
color designations stated for the new variety may vary, depending
upon variations in environmental factors, including weather
(temperature, humidity and light intensity), day length, soil type,
location and cultural conditions. `FLEURTAI` has not been observed
under all possible environmental conditions.
