Strawberry plant named ‘CIVRH621’

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.

Claims

1. A new and distinct strawberry plant named CIVRH621, as herein described and illustrated by the characteristics set forth above.

(2) 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.

(3) FIG. 1 shows typical plant of CIVRH621;

(4) FIG. 2 shows typical flowers of CIVRH621;

(5) FIG. 3 shows typical leaves of CIVRH621;

(6) FIG. 4 shows typical fruits of CIVRH621.

DETAILED BOTANICAL DESCRIPTION

(7) 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.

(8) 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.

(9) 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.

(10) 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.

(11) The following tables 3-9 describe fruit, plant, stolon, foliage, fruiting truss, flower and pest/disease characteristics of the new strawberry CIVRH621.
