Strawberry plant named ‘ISCHIA’

Abstract

A new and distinct variety of Fragaria L. named ‘ISCHIA’, characterized by the description herein.

Description

Latin name of the genus and species claimed: Fragaria L.

Variety denomination: ‘ISCHIA’.

PRIORITY CLAIM

This application claims the benefit of European Community Plant Variety Office Plant Breeders' Rights Application No. 2011/0358, filed Feb. 14, 2011.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘ISCHIA’, which was the result of a controlled cross between the strawberry variety ‘CIVRI30’ (Breeder reference, unpatented) and a not released selection of Consorzio Italiano Vivaisti named ‘O2N2-19’.

The progeny was first asexually propagated by stolons in S. Giuseppe di Comacchio Ferrara, Italy, in 2005.

The ‘ISCHIA’ variety was tested over the next several years in different European areas with continental climates. The tests started in 2006 and continued until 2010.

BRIEF SUMMARY OF THE INVENTION

Plants of the new Strawberry variety ‘ISCHIA’ can be distinguished from plants of the Strawberry variety ‘CIVRI30’ by the following unique combination of characteristics described in Table 1:

TABLE 1
Comparison with Comparison Variety
Denomination	Characteristic in	State of	State of
of	which the similar	expression of	expression of
similar variety	variety is different	similar variety	candidate variety
‘CIVRI30’	Plant Vigor	Weak to Medium	Strong
	Leaf Size	Small to Medium	Medium to Large
	Fruit Color	Orange Red	Medium Red

Plants of the new Strawberry variety ‘ISCHIA’ can be distinguished from plants of the parent Strawberry variety ‘O2N2-19’ by the following unique combination of characteristics described in Table 2:

TABLE 2
Comparison with Parent Variety:
Denomination	Characteristic in	State of	State of
of	which the similar	expression of	expression of
similar variety	variety is different	similar variety	candidate variety
‘O2N2-19’	Fruit color	Deep red	Medium red
		(RHS53A)	(RHS46B)
	Fruit shape	Obloid	Conical

Asexual reproduction of this new variety by stolons shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The new variety reproduces true to type.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Strawberry ‘ISCHIA’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color value cited in the detailed botanical description, which accurately describe the color of ‘ISCHIA’.

FIG. 1 shows the plant of ‘ISCHIA’;

FIG. 2 shows the leaves of ‘ISCHIA’;

FIG. 3 shows the flowers of ‘ISCHIA’; and

FIG. 4 shows the fruits of ‘ISCHIA’.

The colors of this illustration may vary with lighting conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.

DETAILED BOTANICAL DESCRIPTION

The following detailed description of the ‘ISCHIA’ variety, unless otherwise noted, is based on observations taken of plants and fruits, and asexually reproduced progeny, grown at S. Giuseppe di Comacchio, Ferrara, Italy.

The observed plants were one year old plants. The plants used in the production field are produced in a nursery in S. Giuseppe di Comacchio, dug in December, cold stored, and planted in production fields in the middle of April.

Certain characteristics of this variety may change with changing environmental conditions (e.g., light, temperature, moisture, etc.), nutrient availability, or other factors. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average. Color descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Color designations are made with reference to The Royal Horticultural Society (R.H.S.) Color Chart.
