Claims
We claim:
1. A new and distinct variety of Vitis vinifera L. plant
substantially as illustrated and described herein.
Description
Latin name of the genus and species of the plant claimed: Vitis
vinifera L.
Variety denomination: `PINOT ISKRA`.
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of priority from QZ Community
Plant Variety Office (CPVO) Application No. 20183516, filed Dec.
20, 2018.
BACKGROUND
The present application relates to a new and distinct variety of
grape named `PINOT ISKRA`. Our new plant resulted from a controlled
cross and is a selection from crossing SK-00-1/7 (unpatented) as
the seed parent with Pinot Blanc (unpatented) as the pollen parent
in 2005. The resulting plant was selected in 2013 when growing in a
cultivated area in Udine, Italy.
`PINOT ISKRA` 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.
SUMMARY
The `PINOT ISKRA` variety is distinguished from other grape
varieties due to the following unique combination of
characteristics: resistance to downy mildew and powdery mildew,
strong blistering on the upper side of the leaf blade, early-medium
harvesting time (end of August in northeastern Italy), and
semi-erect shoot attitude. A comparison of the new variety to its
parents, Vitis vinifera `Pinot blanc` (unpatented) and Vitis cross
`SK-00-1/7` (unpatented), is provided in Table 1.

Of the many commercial cultivars known to the inventor, the most
similar to the new grapevine `PINOT ISKRA` is the male parent
`Pinot blanc`, to which a comparison has been provided above.
Asexual reproduction of this new variety by grafting onto K5BB
rootstock was first performed in February 2014 in Rauscedo, Friuli
Venezia Giulia Region, Italy, and has demonstrated that that the
foregoing characteristics for the new cultivar come true to form,
are firmly fixed, and are established and transmitted through
succeeding propagations. The new cultivar reproduces true to
type.
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, 5.sup.th edition,
London, England, 2007.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a photograph showing a shoot a leaf of the new variety
`Pinot Iskra` taken on May 24, 2017, in Rauscedo, Italy.
FIG. 2 is a photograph showing a leaf of the new variety `Pinot
Iskra` taken on May 24, 2017, in Rauscedo, Italy.
FIG. 3 is a photograph showing fruit of the new variety `Pinot
Iskra` taken on Aug. 24, 2016, in Rauscedo, Italy.
FIG. 4 is a photograph showing a plant of the new variety `Pinot
Iskra` taken on Aug. 24, 2016, in Rauscedo, Italy.
The color photograph shows 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 photograph alone.
DETAILED DESCRIPTION
Botanical
The following detailed description of the `PINOT ISKRA` 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.degree. C. to a low of -2.degree. C. Average rainfall
is 822 mm per year, with an average rainfall during the growing
season (April-September) of 453 mm.
