Grapevine named `SAUVIGNON KRETOS`
Abstract
A new and distinct variety of grapevine named `SAUVIGNON
KRETOS`, primarily adapted to the growing conditions of the
temperate regions, and characterized by its strong vigor; erect
growth habit; wedge-shaped leaves with medium texture; medium
weight and conical shaped berry clusters; early maturing, firm
berry flesh with no coloration and neutral taste primarily for
winemaking; early harvesting time; and resistance to winter
temperatures (to -22.degree. C.), resistance to downy mildew and
tolerance to powdery mildew.

Claims
What is claimed is:
1. A new and distinct grapevine, referred to as `SAUVIGNON KRETOS`,
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: `SAUVIGNON KRETOS`.
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 `SAUVIGNON KRETOS`.
The new grapevine `SAUVIGNON KRETOS` 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 `SAUVIGNON KRETOS` originated from a cross made
by the inventors in 2002 in Udine, Italy. The female or seed parent
is the grapevine variety Vitis vinifera `Sauvignon` (unpatented),
and the male or pollen parent is the grapevine variety Vitis `20/3`
(Bianca.times.SK77-4/5) (unpatented).
The new grapevine `SAUVIGNON KRETOS` 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
`SAUVIGNON KRETOS` 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 `SAUVIGNON KRETOS`,
which in combination distinguish this grapevine plant as a new and
distinct variety. 1. Strong vigor; 2. Erect growth habit; 3.
Wedge-shaped leaves with a medium green upper surface and light
green lower surface and a medium texture; 4. Fruit clusters with
medium weight, conical shape, firm berry flesh with neutral taste,
and no flesh coloration, early maturity (end of August in Middle
Friuli, North-Eastern Italy); and primarily used for wine. 5.
Primocanes and floricanes with an elliptic cross section, brownish
color, no lenticels, and small internodes of 8 mm diameter; 6.
Early harvesting time, at end of August in Middle Friuli,
North-Eastern Italy; and 7. Resistance to winter temperature
(-22.degree. C.), resistance to downy mildew, and tolerant to
powdery mildew, if overripening is allowed it is susceptible to
cluster rots.
Plants of the new grapevine `SAUVIGNON KRETOS` differ from plants
of the parents, Vitis vinifera `Sauvignon` (unpatented) and Vitis
`20/3` (unpatented), in the following characteristics described in
Table 1.

DETAILED BOTANICAL DESCRIPTION
The following description of `SAUVIGNON KRETOS` unless otherwise
noted, is based on observations taken during the 2011, 2012, and
2013 growing seasons 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. `SAUVIGNON KRETOS` has
not been observed under all possible environmental conditions.
Color references are made to The Royal Horticultural Society Colour
Chart (R.H.S.), (Edition V, 2007), except where general colors of
ordinary significance are used.
