Patent Grant
PP29370
Latin name of the genus and species of the plant claimed: ‘MARYS PEAK’ is a new strawberry plant that is Fragaria xananassa Duchesne ex Rozier.
Variety denomination: The new strawberry plant claimed is of the variety denominated ‘Marys Peak’, Fragaria xananassa Duchesne ex Rozier.
The present invention relates to a new and distinct strawberry cultivar designated ‘Marys Peak’ and botanically known as Fragaria xananassa Duchesne ex Rozier. This new strawberry cultivar was discovered in Corvallis, Oreg. in June 2002 and originated from a cross between the female parent ‘Pinnacle’ (unpatented) and the male parent ‘ORUS 1723-3’ (unpatented). The original seedling of the new cultivar was asexually propagated via tissue culture and vegetative cuttings since 2002 in Benton County, Oreg. The present invention has been found to be stable and to reproduce true to type through successive asexual propagations.
The accompanying color photographs show typical specimens of the new cultivar at various stages of development as nearly true as it is possible to make in color reproductions.
The following description of ‘Marys Peak’ is based on observations taken from 2004 to 2016 growing seasons in trials in Corvallis and Aurora, Oreg. This description is in accordance with UPOV terminology. Color designations, color descriptions and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. ‘Marys Peak’ has not been observed under all possible environmental conditions. The botanical description of ‘Marys Peak’ was taken from plants one year after establishment in the field. Color terminology follows The Royal Horticultural Society Colour Chart. London (R.H.S.) (5th edition, 2007).
Table 1 shows plant characteristics of the new cultivar. Plant characteristics include plant height, diameter, number of crowns per plant, habit, density of individual plants and vigor.
Table 2 shows leaf characteristics of the new cultivar. Leaf characteristics include leaf type, leaf length, leaf width, terminal leaflet length, terminal leaflet width, terminal leaflet length to width ration, leaf margins, shape of teeth, leaf serrations per leaflet, upper and lower leaf surface color, number of leaflets, terminal leaflet apex shape, terminal leaflet base shape, glossiness upper side leaf surface, texture upper side leaf surface, texture underside leaf surface and leaf arrangement.
Table 3 shows information about the petiole, the petiolule, the bract and the stipule of the new cultivar. This includes petiole length, petiole diameter, petiole pubescence, petiole color, petiolule color, petiolule length, bract frequency, texture petiole, stipule length, and stipule width.
Table 4 shows stolen characteristics of the new cultivar. These characteristics include the number of stolons, the anthocyanin coloration of the stolons, the thickness of the stolons, and the pubescence of the stolons.
Table 5 shows inflorescence characteristics of the new cultivar. These characteristics include inflorescence position relative to foliage, flower type, flower size, petal shape, relative petal spacing, petal apex shape, petal margin, petal base shape, petal length, petal width, petal length/width ratio, number of petals, petal color, stigma color, style color, anther color, filament color, and flower truss type.
Table 6 shows fruit characteristics of the new cultivar. These characteristics include number of berries per truss, fruiting truss attitude, fruit length, fruit diameter, fruit length/width ratio, fruit weight, relative fruit size, predominant fruit shape, difference in shape between primary and secondary fruit, band without achenes, evenness of fruit surface, top color, non-blush side color, blush side color, internal color, achene color, achene count per fruit, insertion of calyx, pose of calyx segments, size of calyx in relation to fruit, ease of calyx removal, firmness of flesh, evenness of flesh color, distribution of flesh color, sweetness, acidity, Brix, pH, titratable acidity, texture when tasted, time of flowering, harvest maturity (50% of plants with ripe fruit), type of bearing, and yield in 1st and 2nd harvest seasons.
When ‘Marys Peak’ is compared to female parent ‘Pinnacle’ (unpatented), the fruit are deeper red, slightly conic to wedge shaped, and more uniformly shaped.
When ‘Marys Peak’ is compared to the male parent ORUS 1723-3 (unpatented) the fruit are much larger and firmer and the plants have a much more upright and open canopy.
When ‘Marys Peak’ is compared to the commercial variety ‘Totem’ (unpatented) and ‘Tillamook’ (unpatented), ‘Marys Peak’ has large, firm, lighter colored fruit and an open plant canopy and ripens in the late midseason, ‘Totem’ has medium sized, soft, dark fruit, and a dense plant canopy and ripens in midseason, and ‘Tillamook’ has large, firm, lighter colored fruit and an open plant canopy and ripens in early midseason.
