Abstract

This invention relates to a new and distinct variety of strawberry plant named ‘CIVRH621’. This new everbearer strawberry plant named ‘CIVRH621’ is primarily adapted to the climate and growing conditions of the high chill areas. It is characterized as a rustic plant resistant to mildew with a robust and efficient root system tolerant to diseases, suitable for organic cultivation. ‘CIVRH621’ has high production during the initial harvesting period but is also long and constant through the season. The plant has high-medium vigor with semi-upright habit and medium density foliage. The fruit has a conical/hearted shape, which is maintained during the whole picking season, very attractive and uniform bright red color, also excellent skin resistance during the summer with good shelf life. The aroma of the fruit is intense and persistent with very pleasant organoleptic characteristics and an ideal balance between sweetness and acidity. Fruit picking is easy and fast.

Description

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

Variety denomination: ‘CIVRH621’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘CIVRH621’.

The new strawberry ‘CIVRH621’ is a product of a planned breeding program conducted by the inventor(s), Leis Michelangelo and Martinelli Alessio, in San Giuseppe di Comacchio (Ferrara), Italy. The objective of the breeding program is to develop new everbearer strawberry varieties with high chill requirement, rustic plants with robust and efficient root systems and good tolerance to diseases. Plants show resistance to mildew and are suitable for organic cultivation. Select fruits with very pleasant organoleptic characteristic and ideal balance between sweetness and acidity.

This new strawberry ‘CIVRH621’ 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 3H1F-11. The male or pollen parent is the not released selection of Consorzio Italiano Vivaisti named S7V9-9.

The new strawberry ‘CIVRH621’ 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 high chill conditions. 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

‘CIVRH621’ is an everbearer variety with high chill requirement.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘CIVRH621’, which in combination distinguish this strawberry plant as a new and distinct variety:

- 1. everbearer variety with high chill requirement;
- 2. rustic plant resistance to mildew with good tolerance to root system disease;
- 3. robust and efficient root system;
- 4. very high productivity, long and constant through the season;
- 5. bright red color, attractive and uniform; and
- 6. easy and fast fruit picking.

Of the many commercial cultivars known to the present inventor, the most similar in comparison to the new strawberry variety ‘CIVRH621’ is the patented strawberry variety Murano. Plants of the new strawberry variety ‘CIVRH621’ differ from plants of strawberry variety ‘Murano’ 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 ‘CIVRH621’, 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 ‘CIVRH621’.

The depicted plant and plant parts of the new strawberry variety ‘CIVRH621’ were taken in San Giuseppe di Comacchio (Ferrara), Italy, and are approximately 3 to 5 months old.

FIG. 1 shows typical plant of ‘CIVRH621’;

FIG. 2 shows typical flowers of ‘CIVRH621’;

FIG. 3 shows typical leaves of ‘CIVRH621’;

FIG. 4 shows typical fruits of ‘CIVRH621’.

DETAILED BOTANICAL DESCRIPTION

‘CIVRH621’ 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 ‘CIVRH621’, 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 ‘CIVRH621’ 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 ‘CIVRH621’ 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, except where general colors of ordinary significance are used. Color values were taken under daylight conditions at approximately 10:00 A.M. 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 ‘CIVRH621’.
