Abstract
This invention relates to a new and distinct variety of strawberry plant named ‘CIVRL333’. This new strawberry plant named ‘CIVRL333’ is primarily adapted to the climate and growing conditions of the low chill areas but it is also adapted for Northern European countries, Mediterranean and Subtropical areas. It is characterized by a plant with good vigor, upright habit and an excellent tolerance to most common diseases. The fruit is attractive with bright red color, regular shape and big size for the entire picking season and a very resistant skin even at high temperatures. The flesh is juicy, with sweet flavor and lovely aroma. The fruit is unique among the everbearer low chill varieties. Very early and long lasting picking season.
Description

Latin name of the genus and species of the plant claimed: Fragaria x ananassa.


Variety denomination: ‘CIVRL333’.


BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘CIVRL333’.


The new strawberry ‘CIVRL333’ is a product of a planned breeding program conducted by the inventors, Leis Michelangelo and Martinelli Alessio, in San Giuseppe di Comacchio (Ferrara), Italy. The objective of the breeding program is to develop a new everbearer strawberry variety with low chill requirement, wide climatic adaptability and excellent tolerance to most common diseases. Furthermore, they wanted to get a new everbearer low chill variety with very sweet flavor and lovely aroma. Lastly, the variety must be very early-season and lasting picking time.


This new strawberry ‘CIVRL333’ is a result of a controlled cross made by the inventors in 2011, in San Giuseppe di Comacchio (Ferrara), Italy. The female or seed parent is the not released selection of Consorzio Italiano Vivaisti named R6R11-26. The male or pollen parent is the not released selection of Consorzio Italiano Vivaisti named 3E4L-1.


The new strawberry ‘CIVRL333’ was discovered and selected by the inventors as a single flowering plant within the progeny of the stated cross in 2013 in San Giuseppe di Comacchio (Ferrara), Italy. After its selection, the new variety was asexually propagated by stolons in a nursery located in San Giuseppe di Comacchio (Ferrara), Italy. The new variety was tested over the next several years at Consorzio Italiano Vivaisti in San Giuseppe di Comacchio (Ferrara), Italy and in different European areas with low chill conditions and high chill condition. This propagation 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.


BRIEF SUMMARY OF THE INVENTION

‘CIVRL333’ is an everbearer strawberry variety with low chill requirement but it has a wide climatic adaptability, from Northern European countries to Mediterranean and Subtropical areas.


The following traits have been repeatedly observed and are determined to be unique characteristics of ‘CIVRL333’, which in combination distinguish this strawberry plant as a new and distinct variety:

    • 1. everbearer variety with low chill requirement;
    • 2. wide climatic adaptability;
    • 3. excellent tolerance to most common disease;
    • 4. fruits with regular shape and big size for all the picking season;
    • 5. very resistant fruit skin;
    • 6. bright red color of the fruits;
    • 7. fruit with very sweet flavor, with lovely aroma, unique of king among the everbearer low chill varieties; and
    • 8. very early picking season and long lasting.


Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new strawberry variety ‘CIVRL333’ is the patented strawberry variety Zafir property of Consorzio Italiano Vivaisti. Plants of the new strawberry variety ‘CIVRL333’ differ from plants of strawberry variety Zafir in the characteristics described in Table 2:

BRIEF DESCRIPTIONS OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of typical specimens of the new strawberry variety ‘CIVRL333’, at various stages of development as true as it is reasonably possible with color reproductions of this type. Color in the photographs may differ slightly from the color value cited in the botanical description which accurately describe the color of ‘CIVRL333’. The depicted plant and plant parts of the new strawberry variety ‘CIVRL333’ were taken in San Giuseppe di Comacchio (Ferrara), Italy, and are approximately 3 to 5 months old.

DETAILED BOTANICAL DESCRIPTION

‘CIVRL333’ has not been observed under all possible environmental conditions. The characteristics of the new variety may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location.


The aforementioned photographs, together with the following observations, measurements and values describe the new strawberry variety ‘CIVRL333’, unless otherwise noted, taken during the 2018 growing season in San Giuseppe di Comacchio (Ferrara), Italy. The observations, measurements and values were taken from plants of ‘CIVRL333’ dug from a low-elevation nursery located in San Giuseppe di Comacchio (Ferrara), Italy, during 2018 and planted approximately 4 months later in San Giuseppe di Comacchio (Ferrara), Italy. Plants of the new strawberry variety ‘CIVRL333’ were grown under conditions which closely approximate those generally used in commercial practice.


Yield observations and fruit quality characteristics are averaged from 2 years of data collected from the 2017 through 2018 growing seasons. Flower measurements and characteristics are from secondary flowers unless otherwise noted. Fruit characteristics and measurements are from secondary fruit unless otherwise noted.


Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 2001 edition, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 10:00 in San Giuseppe di Comacchio (Ferrara), Italy. The approximate age of the observed plants is 3 to 5 months.


The following tables 3-9 describe fruit, plant, stolon, foliage, fruiting truss, flower and pest/disease characteristics of the new strawberry ‘CIVRL333’.
