Strawberry plant named ‘Cordial’
This invention relates to a new and distinct cultivar of strawberry named ‘Cordial’. The new late-season cultivar is primarily characterized by the uniformity and symmetry of fruit shape and size, evenness of color, glossiness of fruit skin, freshness and health of calyx, being free of physiologically-based blemishes such sun scald, bronzing, and rain damage and shelf life of the fruit.

Latin name of the genus and species of the plant claimed: ‘Cordial’ is a new strawberry plant that is Fragaria x ananassa Duchesne ex Rozier.
Variety denomination: The new strawberry plant claimed is of the variety denominated ‘Cordial’ Fragaria x ananassa Duchesne ex Rozier.
BACKGROUND OF THE NEW PLANTThe present invention relates to a new and distinct strawberry cultivar designated ‘Cordial’ and botanically known as Fragaria x ananassa Duchesne ex Rozier. This new strawberry cultivar was discovered in Beltsville, Md., in Spring 2013 and originated from a cross between the female parent B1893 (unpatented) and the male parent B1805 (unpatented). The original seedling of the new cultivar was asexually propagated in Beltsville since 2013 by rooting daughter plants from stolons of the mother plant. The present invention has been found to be stable and reproduce true to type through successive asexual propagations rooting daughter plants from stolons.
BRIEF SUMMARY OF THE NEW PLANTThe cultivar ‘Cordial’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Cordial’. These characteristics in combination distinguish ‘Cordial’ as a new and distinct Fragaria cultivar:
-
- 1. Late season.
- 2. Resistant to anthracnose fruit rot (Colletotrichum acutatum).
- 3. Excellent fruit quality in storage (shelf life).
- 4. High yield.
This new strawberry plant is illustrated by the accompanying photographs that show the flowers, fruit and entire plants; the colors shown are as true as can be reasonably obtained by conventional photographic procedures.
The following description of ‘Cordial’ is based on observations taken from 2015 through 2018 growing seasons in evaluations in Beltsville, Md. 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 on variation in environmental, seasonal, climatic, and cultural conditions. ‘Cordial’ has not been observed under all possible environmental conditions. The botanical description of ‘Cordial’ was taken from plants nine months after establishment in the field. Color terminology follows The Royal Horticultural Society Colour Chart, London (1986).
‘Cordial’ fruit are suitable for shipping and fresh-market use, based on a combination of the marketability ratings after refrigerated storage, fruit firmness, and fruit skin toughness. The percent of fruit still at marketable quality (no rot and very little degradation) after refrigerated storage was 86% (1 week) and 52% (2 weeks) for ‘Cordial’, compared with 37% and 10% for ‘Allstar’, and 52% and 15% for ‘Ovation’.
DETAILED BOTANICAL DESCRIPTIONTable 1 shows selected characteristics of the new cultivar compared with plant characteristics of ‘Allstar’ and ‘Ovation’. Characteristics include inflorescence position, stigma color, anther number, harvest maturity, weight of fruit, yield, firmness of flesh, and evenness of flesh color.
Table 2 shows plant characteristics of the new cultivar compared with plant characteristics of ‘Allstar’ and ‘Ovation’. Plant characteristics include plant height, diameter, number of crowns per plant, habit, density of individual plants and vigor.
Table 3 shows leaf characteristics of the new cultivar compared with leaf characteristics of ‘Allstar’ and ‘Ovation’. Leaf characteristics include leaf type, leaf shape. leaf length, leaf width, terminal leaflet length, terminal leaflet width, terminal leaflet length to width ratio, 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 4 shows information about the petiole, the petiolule, the bract and the stipule of the new cultivar compared to ‘Allstar’ and ‘Ovation’. This includes petiole length, petiole diameter, petiole texture, petiole pubescence, petiole color, petiolule color, petiolule length, bract frequency, bract color designation, stipule length, stipule width, stipule color designation and anthocyanin intensity.
Table 5 shows stolon characteristics of the new cultivar compared to ‘Allstar’ and ‘Ovation’. 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 6 shows inflorescence characteristics of the new cultivar compared to ‘Allstar’ and ‘Ovation’. 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, flower truss type, and anther number.
Table 7 shows fruit characteristics of the new cultivar compared to ‘Allstar’ and ‘Ovation’. 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, fruit glossiness, fruit core color, fruit cavity size, band without achenes, evenness of fruit surface, top color, non-blush side color, blush side color, internal color, achene color, achene count per fruit, calyx color, 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.
When ‘Cordial’ is compared to female parent, B1893 (unpatented), the fruits are less susceptible to Botrytis fruit rot (Botrytis cinerea). When ‘Cordial’ is compared to male parent, B1805 (unpatented), a full sibling of ‘Keepsake’ (U.S. Plant Pat. No. 30,578), the fruits are more resistant to anthracnose fruit rot (Colletotrichum acutatum) and produce more stolons (runners). ‘Cordial’ plants respond to powdery mildew (Spaerotheca macularis), leaf blight (Phomopsis obscurans), leaf scorch (Diplocarpon earliana), and common leaf spot (Mycosphaerella fragariae) similarly to those of ‘Allstar’ and are less susceptible than ‘Ovation’ plants. ‘Cordial’ plants respond to bacterial angular leafspot (Xanthomonas fragariae) similarly to those of ‘Ovation’ and are less susceptible than ‘Allstar’ plants.
Claims
