Botanical classification: Fragaria x ananassa Duchesne ex Rozier.
Variety denomination: The new plant has the varietal denomination ‘Plared 0822’.
This application claims the benefit of European Community Plant Variety Office Application No. 2017/2579, for a strawberry variety named ‘Plared 0822,’ filed on Oct. 13, 2017, the entirety of which is incorporated by reference herein.
Disclosed herein is a new and distinct strawberry variety. The varietal denomination of the new variety is ‘Plared 0822’. The new variety was designated by the breeder as ‘08.16R.124’. The new variety of strawberry was created in a breeding program by crossing two parents in Cartaya (Huelva), Spain about 7° W, 37° N, 45 feet elevation (15 meters high); in particular, by crossing as seed parent an undistributed strawberry parent designated ‘00-174R’ (unpatented) and as pollen parent an undistributed strawberry parent designated ‘09-030’ (unpatented). Each parent is a selection from breeder's program and has not been commercialized.
The resulting seedling of the new variety was grown and asexually propagated by Alexandre Pierron-Darbonne by runners in Segovia, Spain, 3° 59′W., 41° 22′N., 2742 feet elevation and it was successively propagated by runners first into a Screen-House, and after in the fields. Plants of the new variety were further asexually propagated and extensively tested. In order to establish and bring to health the initial head clones, mother plants that had developed several stolons were subjected to a heat treatment, or Thermotherapy, at 36° C.-37° C. for 3 to 4 weeks. After that treatment, apical meristems were cut and developed (1 apical meristem corresponding to 1 rooting plant) in a vitro culture for 5 to 6 weeks. This propagation and testing has demonstrated that the combination of traits disclosed herein which characterize the new variety are fixed and retained true to type through successive generations of asexual reproduction.
The growing period in Cartaya (Huelva), Spain, about 7° W, 37° N, 45 feet elevation (15 meters high), where the observations were made, is between about August 5 and December 31 of each year with a date of first flowering on September 10, for Fall plantation, and between about September 25 and May 20 of next year with a date of first flowering on November 1 for Summer plantation. The location where the observations were made is Cartaya (Huelva), Spain and it is believed to apply to plants grown under similar conditions of soil and climate elsewhere.
Among the characteristics which appear to distinguish the new variety from other varieties are a combination of traits which include inflorescence that appears above the foliage, the flower shows a larger size of calyx relative to corolla; medium to large size fruit that is medium red colored, conical shaped, and firm, having medium red colored flesh; and very early time of flowering and ripening. ‘Plared 0822’ is a fully remontant variety.
The new variety ‘Plared 0822’ is distinguished from others cultivars by showing the inflorescence above the foliage, the flower show a larger size of calyx relative to corolla, the fruit shows a conical shape, with medium to large size, and medium red color, the fruit is firm and it shows a medium red colored flesh, it is has very early flowering and ripening times.
The new variety ‘Plared 0822’ is distinguished therefrom its Seed parent ‘00-174R’ (unpatented) in that the shape of the base in the terminal leaflet of the seed parent is obtuse, the seed parent shows a dark green upper side leaf color, the flower of the seed parent shows the same size of calyx in relation to corolla, and the seed parent shows a dark red fruit color.
The new variety ‘Plared 0822’ is distinguished there from its pollen parent ‘09-030’ (unpatented) in that in the pollen parent shape of base in terminal leaflet is obtuse, the pollen parent shows a dark green leaf color of upper side, the arrangement of petals in the flower of pollen parent is touching, and the fruit of pollen parent shows the same length in relation to width.
The new variety ‘Plared 0822’ is closest to the variety ‘San Andreas’ (U.S. Plant Pat. No. 19,975) but is distinguished by the following characteristics possessed by ‘Plared 0822’ which are different, or not possessed by, ‘San Andreas’ (U.S. Plant Pat. No. 19,975).
Plant of ‘San Andreas (U.S. Plant Pat. No. 19,975) shows a semi-upright growth habit, whereas “Plared 0822” shows an upright habit.
Leaf of ‘San Andreas’ (U.S. Plant Pat. No. 19,975) shows an RHS green group color in the upperside (near 135 B to 135 A), whereas the new variety ‘Plared 0822’ shows an RHS green group color in the upperside (near 141 B to 143 A).
Terminal leaflet in ‘San Andreas’ (U.S. Plant Pat. No. 19,975) shows an obtuse shape of base, whereas in the new variety ‘Plared 0822’ terminal leaflet shows an acute shape of the base.
Position of inflorescence in relation to foliage in ‘San Andreas’ (U.S. Plant Pat. No. 19,975) is at same level, whereas in the new variety ‘Plared 0822’ the inflorescence is above the foliage.
Attitude of sepals in fruit of ‘San Andreas’ (U.S. Plant Pat. No. 19,975) is outwards, whereas the attitude of sepals in fruit of ‘Plared 0822’ is upwards. Petals are touching in the flower of ‘San Andreas’ (U.S. Plant Pat. No. 19,975), whereas petals are overlapping in the flower of ‘Plared 0822’.
Time of beginning of fruit ripening in ‘San Andreas’ (U.S. Plant Pat. No. 19,975) is early, whereas time of beginning of fruit ripening in ‘Plared 0822’ is very early.

The following description is in accordance with UPOV terminology and the color terminology herein is in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.), 3rd edition published in 1995.
The color descriptions and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions.
Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech is aptly descriptive. Color names beginning with capital letter designate values based upon The R.H.S. Colour Chart published by The Royal Horticultural society, London, England, 1995.
The following detailed description of the new variety is based upon observations taken of plants and fruits grown under tunnel, in the farm La Mogalla, in Cartaya (Huelva), Spain, 7° W., 37° N., 45 feet elevation (14 meters high).
The new variety is principally propagated by way of runners. Although propagation by runners is presently preferred, other known methods of propagating strawberry plants may be used. Strawberries root well after transplanting.
The term “blistering” used herein refers to the texture or rugosity or surface undulation inherent to leaves and is generally a constant characteristic.
‘Plared 0822’ is a fully remontant variety. ‘Plared 0822’ is self-fertile. It produces large quantities of pollen throughout the seasons and pollination is generally good as there are very few malformed fruit.
Trials were pursued in the field “La Mogalla” in Cartaya (Huelva), Spain, about 7° W, 37° N, 45 feet elevation (14 meters high). Frigo plants were planted on August 5 (Summer Planted) to produce fruits in autumn and fresh plants were planted on September 25 (Fall Planted) to produce fruits during the spring of following year, with a sample size of two repetitions and 250 plants per repetition in each date of plantation. After planting, plants are grown in raised beds covered with plastic and with small holes in plastic walls, under tunnels. Water and fertilizer are applied through drip irrigation.
