PP22506
Botanical classification: Fragaria×ananassa ‘SABRINA’.
Varietal denomination: The new plant has the varietal denomination Duch.
The new variety of strawberry was created in a breeding program by crossing two parents; in particular, by crossing as seed parent an undistributed strawberry parent designated 9719 (unpatented) and as pollen parent an undistributed strawberry parent designated 94-020 (unpatented). Female and male are selections from breeder's program of Planasa. Both parental varieties are property and have not been commercialized.
The resulting seedling of the new variety was grown and asexually propagated by runners in Segovia, Spain, 3° 59′W., 41° 22′N., 2742 feet elevation. Clones of the new variety were further asexually propagated and extensively tested. 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.
In seed parent 9719 (unpatented) the fruit size is smaller than in the new variety ‘SABRINA’. In seed parent 9719 (unpatented) the terminal leaflet is as long as broad and shows a base shape obtuse, whereas in the new variety ‘SABRINA’ the terminal leaflet is longer than broad and shows a shape of base acute. Attitude of the calyx segments in the fruit of seed parent 9719 (unpatented) is reflexed, whereas in the new variety ‘SABRINA’ is spreading. Plant of pollen parent 94-020 (unpatented) is less vigorous than the plant of the new variety ‘SABRINA’. In pollen parent 94-020 (unpatented) the position of the inflorescence relative to the foliage is above, whereas in the new variety ‘SABRINA’ is level with the foliage. In pollen parent 94-020 (unpatented) the fruit size is smaller than in the new variety ‘SABRINA’.
The present invention relates to a new and distinct strawberry variety. The varietal denomination of the new variety is ‘SABRINA’. 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, same size of calyx relative to corolla and abundant production of red colored, conical shaped, and firm fruit, large fruit size, and medium time of ripening (50% of plants with ripe fruits).
The new variety is closest to the variety ‘Sabrosa’ (U.S. Plant Pat. No. 16,558) and the variety ‘Camarosa’ (U.S. Plant Pat. No. 8,708), but is distinguished therefrom by the following characteristics possessed by ‘Sabrina’ which are different than, or not possessed by, ‘Sabrosa’ (U.S. Plant Pat. No. 16,558) or ‘Camarosa’ (U.S. Plant Pat. No. 8,708).
The differences in the length/width ratio and shape of base in the terminal leaflet of ‘Sabrina’ (designated 03.40.181) and ‘Camarosa’ (U.S. Plant Pat. No. 8,708) and ‘Sabrosa’ (U.S. Plant Pat. No. 16,558) are shown in
The accompanying photographs show typical specimens of the new variety, designated 03.40.181 in the illustrations, including fruit, foliage and flower, in color as nearly true as it is reasonably possible to make in color illustrations of this character.
The plants depicted in the drawings were planted Oct. 10, 2009 in the farm of La Mogalla in Cartaya (Huelva), Spain, about 7° W, 37° N, 45 feet elevation.
Drawings were taken March-April, 2010 (about March 25 and Apr. 8, 2010): minimum temperate about 10 to 12° Centigrade, maximum temperate about 22 to 24° Centigrade.
The following detailed description of the new variety is based upon observations taken of plants and fruits grown “underglass”, i.e. undertunnel, in the farm of La Mogalla in Cartaya (Huelva), Spain, 7° W., 37° N., 45 feet elevation.
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.), Third 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.
The new variety is principally propagated by way of runners. Although propagation by runners is presently preferred, other know 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 ondulation inherent to leaves and is generally a constant characteristic.
‘Sabrina’ 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). Usually a short time is sufficient. ‘Sabrina’ is self-fertile. It produces large quantity of pollen throughout the seasons and pollination is generally good as there are very few malformed fruit.
The following definitions apply:
Firmness: It is the fruit's resistance to penetration measured in Kilograms (Kg). The measure given has been obtained by the penetrometer ROZE Mod. Arbelette, with a 50 mm2 section head.
Dry Matter: It is the weight of the residual left from the trituration of the fruit after the drying process at a temperature of 103° C.±2° C. until reaching constant weight.
Humidity & Volatile Matter: Represents the content in volatile matters and water of the fruits.
(%) Humidity & Volatile Matter=100−% Dry Matter
Maturity Index: Relation between Soluble solids and Acidity as Anhydride Citric.
The following additional information is provided to further describe the new variety.
