CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of European Community Plant Variety Office Application No. 2019/1672, for a strawberry variety named ‘Plared1075’, filed on Jul. 9, 2019, the entirety of which is incorporated by reference herein.

BACKGROUND

Disclosed herein is a new and distinct strawberry variety (Fragaria x ananassa Duchesne ex Rozier). The varietal denomination of the new variety is ‘Plared 1075’. The new variety was designated by the breeder as ‘10.09.214’. The new variety of strawberry was created in a breeding program by crossing two parental varieties in 2010 in Cartaya (Huelva), Spain (about 7° W, 37° N, and 45 feet elevation). The seed parent was an undistributed strawberry variety designated ‘06-49’ (unpatented) and the pollen parent was an undistributed strawberry variety designated ‘09-024’ (unpatented). Each parental variety was a selection from the 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., at 2742 feet elevation) and it was successively propagated by runners first into a screen-house, and afterwards 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 an in vitro culture for 5 to 6 weeks. This propagation and testing have demonstrated that the combination of traits disclosed herein which characterize the new variety are retained true to type through successive generations of asexual reproduction.

The growing period in Cartaya (Huelva), Spain (about 7° W, 37° N, and 45 feet elevation), where the observations were made, is between about October 14 and May 20 of the following year, with a date of first flowering of November 20. The observed characteristics are believed to apply to plants grown under similar conditions of soil and climate elsewhere. ‘Plared 1075’ is a short variety that benefits from induction to flowering by chilling, usually a few hours are sufficient, preferably at temperatures of 7° C. or less. Normally, the minimum number of hours is accumulated in the field over several days.

SUMMARY

Among the characteristics which appear to distinguish the new variety from other varieties are a combination of traits which include inflorescence that appears level with the foliage, slightly larger size of calyx in relation to diameter of fruit, abundant production of medium sized, medium-red colored, conical shaped, and firm fruit, and early time of flowering and ripening. ‘Plared 1075’ is a not remontant variety.

COMPARISON TO THE PARENTS

The new variety ‘Plared 1075’ is distinguished from its seed parent ‘06-49’ (unpatented) in that the fruit of the seed parent shows an inserted position of calyx attachment and an attitude of sepals upwards to outwards. In contrast, the attitude of the sepals in the fruit of ‘Plared 1075’ is outwards and slightly upwards and the calyx attachment is level.

The new variety ‘Plared 1075’ is distinguished from its pollen parent ‘09-024’ (unpatented) in that the fruit of pollen parent is cylindrical shaped, dark red color, and shows a raised position of calyx attachment and the core is medium red colored. In contrast, the fruit of ‘Plared 1075’ is conical shaped, medium-red colored, and the core is strong red to moderate reddish orange.

COMPARISON TO CLOSEST VARIETY

The new variety ‘Plared 1075’ is closest to the variety ‘Florida Radiance’ (U.S. Plant Pat. No. 20,363) but is distinguished by a number of characteristics.

The terminal leaflet in ‘Florida Radiance’ shows an obtuse shape of the base, whereas in the new variety ‘Plared 1075’ the terminal leaflet shows an acute shape of the base.

The margin of the terminal leaflet of ‘Florida Radiance’ is crenate, whereas the margin of the terminal leaflet of the new variety ‘Plared 1075’ is serrate to crenate.

‘Florida Radiance’ shows a red fruit color of RHS Red group near 43 B to 44 C, whereas in ‘Plared 1075’ the red fruit color is RHS Red group near 44 B to 44 A.

The position of the calyx attachment in the fruit of ‘Florida Radiance’ is raised, whereas the position of the calyx attachment in the fruit of ‘Plared 1075’ is level with the fruit.

The attitude of the sepals in the fruit of ‘Florida Radiance’ is upwards, whereas the attitude of the sepals in the fruit of ‘Plared 1075’ is outwards and slightly upwards.

The diameter of the calyx in relation to the diameter of the fruit in ‘Florida Radiance’ is slightly smaller, whereas the diameter of the calyx in relation to the diameter of the fruit in ‘Plared 1075’ is slightly larger.

The time of beginning of flowering in ‘Florida Radiance’ is very early, whereas the time of beginning of flowering in ‘Plared 1075’ is early.

The time of beginning of fruit ripening in ‘Florida Radiance’ is very early, whereas the time of beginning of fruit ripening in ‘Plared 1075’ is early.

FIG. 14 shows the differences in the upper side color of the leaf of ‘Plared 1075’ (designated 10.09.214 in the figure) and ‘Florida Radiance’. FIG. 15 shows the differences in the shape of the base in the terminal leaflet and the margin of the terminal leaflet of ‘Plared 1075’ (designated 10.09.214 in the figure) and ‘Florida Radiance’. The differences in the fruit color, position of the calyx attachment, the attitude of sepals and the diameter of the calyx in relation to the diameter of the fruit are shown in FIG. 16 and FIG. 17. These differences are maintained during the harvest season.

DESCRIPTION OF THE NEW VARIETY

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech is apply 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 color descriptions and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions.

The following detailed description of the new variety is based upon observations taken of plants and fruits grown under tunnel at the farm La Mogalla, in Cartaya (Huelva), Spain (7° W., 37° N., 45 feet elevation). Plants were planted on October 14 with a sample size of two repetitions and 250 plants per repetition. After planting, plants were grown under tunnels in raised beds covered with plastic and with small holes in plastic walls. Water and fertilizer were applied trough drip irrigation.

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 1075’ is a short day variety that needs an induction to flowering by chilling, such as occurs at a high elevation nursery (fresh plant) or with cold storage (referred to as a frigo plant). Usually a short time (several hours) is sufficient. ‘Plared 1075’ is self-fertile. It produces large quantities of pollen throughout the season and pollination is generally good as there are very few malformed fruit.
