Botanical classification: Fragaria×ananassa Duchesne ex Rozier.
Variety denomination: The new plant has the varietal denomination ‘Planasa 0955’.
This application claims the benefit of European Community Plant Variety Office Application No. 2016/1836, for a strawberry variety named ‘Planasa 0955,’ filed on Jul. 22, 2016, 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 ‘Planasa 0955’. The new variety was designated by the breeder as ‘09.24.197’ . The new variety of strawberry was created in a breeding program by crossing two parents in 2009 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 ‘09-024’ (unpatented) and as pollen parent an undistributed strawberry parent designated ‘03-98’ (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 October 13 and May 11 of each year with a date of first flowering on November 11. 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. ‘Planasa 0955’ 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 during several days.
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, larger size of calyx relative to corolla and abundant production of medium red colored, conical shaped, and firm fruit, medium to large fruit size, orange red colored flesh, medium time of flowering and ripening. ‘Planasa 0955’ is a not remontant variety.
The new variety ‘Planasa 0955’ is distinguished from others cultivars by showing the inflorescence at same level with the foliage, the shape of the base of terminal leaflet is acute, it shows a conical shape fruit with a medium red color, the fruit is firm and it shows a medium to large size with an orange red colored flesh and it has medium flowering and ripening times.
The new variety ‘Planasa 0955’ is distinguished therefrom its Seed parent ‘09-024’ (unpatented) in that the seed parent length in relation to width of terminal leaflet is equal, the shape of base in terminal leaflet is obtuse, the seed parent shows a medium fruit size.
The new variety ‘Planasa 0955’ is distinguished there from its pollen parent ‘03-98’ (unpatented) in that in the pollen parent, the leaf color of upper side is dark green with medium glossiness, the flower of pollen parent shows a same size of calyx in relation to corolla.
The new variety ‘Planasa 0955’ is closest to the variety ‘Sabrina’ (U.S. Plant Pat. No. 22,506) but is distinguished by the following characteristics possessed by ‘Planasa 0955’ which are different, or not possessed by, ‘Sabrina’ (U.S. Plant Pat. No. 22,506).

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 (15 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.
‘Planasa 0955’ 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 is sufficient. ‘Planasa 0955’ 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 (15 meters high). Plants were planted on October 13 with a sample size of two repetitions and 250 plants per repetition. 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.
