Description
[0001] Genus and species: Fragaria×ananassa.
[0002] Variety denomination: ‘DrisStrawThree’.
Background of the New Plant
[0003] The present invention relates to a new and distinct strawberry cultivar designated ‘DrisStrawThree’ and botanically known as Fragaria×ananassa. This new strawberry cultivar was discovered in October, 2002 and originated from a cross between the female parent ‘5F205’, a proprietary strawberry plant (unpatented) and the male parent ‘San Juan’ (U.S. Plant Pat. No. 12,899). The original seedling of the new cultivar was asexually propagated at a nursery in Shasta County, Calif. ‘DrisStrawThree’ was subsequently asexually propagated and underwent further testing at a nursery in Ventura County, Calif. for four years. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.
Description of the Photographs
[0004] 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.
[0005] FIG. 1 shows overall plant habit including fruit at various stages of development.
[0006] FIG. 2 shows leaves of the plant with three leaflets.
[0007] FIG. 3 shows both the upperside and underside of several of the flowers.
[0008] FIG. 4 shows the whole fruit.
[0009] FIG. 5 shows the fruit in longitudinal cross-section.
Description of the New Cultivar
[0010] The following description of ‘DrisStrawThree’ is based on observations taken from the 2002 to 2006 growing seasons in Ventura County, Calif. 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. ‘DrisStrawThree’ has not been observed under all possible environmental conditions. Color terminology follows the Royal Horticultural Society Colour Chart, London (R.H.S.) (2001).
