Strawberry plant named ‘Driscoll Atlantis’
This invention relates to a new and distinct variety of strawberry named ‘Driscoll Atlantis.’ The variety is similar to the varieties ‘Biscayne’ and ‘Key Largo.’ The variety is distinguished from ‘Biscayne’ and ‘Key Largo,’ in particular, by its shorter average stipule length, reduced frequency of paired bracts, shorter sepal length and width, weak leaf glosiness, dense stipule pubescence, and a very narrow band on the fruit where achenes are absent.
1. Latin name of the genus and species of the plant claimed: The variety is botanically identified as Fragaria×ananassa.
1.1 Variety denomination: The strawberry variety denomination is ‘Driscoll Atlantis’.
2. BACKGROUND OF THE INVENTIONThe new variety originated as a result of a controlled cross between the strawberry plants ‘88E94’ (unpatented variety) and Mirador (U.S. Plant Pat. No.: 11,279) in an ongoing breeding program, and was discovered as a seedling in Hillsborough, Fla. in 1999. The original seedling of the new cultivar was asexually propagated by stolons in a Nursery in Shasta County, Calif. Propagules were transplanted to a controlled breeding plot in Hillsborough County, Fla., where the variety was identified and selected for further evaluation. ‘Driscoll Atlantis’ was subsequently asexually propagated and underwent further testing in Hillsborough County, Fla. for three years. 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.
3. SUMMARY OF THE INVENTIONThe present invention relates to a new and distinct variety of strawberry named ‘Driscoll Atlantis.’ The variety is botanically identified as Fragaria×ananassa. The new variety is distinguished from other varieties by a number of characteristics as set forth in Tables 1-4.
4. COMPARISON TO SIMILAR VARIETIESThe varieties which we believe to be similar to ‘Driscoll Atlantis’ from those known to us are ‘Biscayne’ (U.S. Plant Pat. No. 12,186) and ‘Key Largo’ ( U.S. Plant Pat. No. 8,649). There are several characteristics of the new variety that are different from, or not possessed by ‘Biscayne’ and ‘Key Largo’. The new variety has a shorter average stipule length, a reduced frequency of paired bracts, a shorter sepal length and width, weak leaf glosiness, dense stipule pubescence, and a very narrow band on the fruit where achenes are absent.
‘Driscoll Atlantis’ is distinguished from its parents ‘88E94’ and ‘Mirador’ by being partially everbearing, in comparison to the fully everbearing trait of both parents.
The accompanying photographs show typical specimens of the new variety, including fruit, foliage and flowers, in color as nearly true as it is reasonably possible to make in color illustrations of these characteristics.
The following detailed description of the new variety is based upon observations taken of plants and fruit grown in Hillsborough County, Fla., U.S.A. This description is in accordance with UPOV terminology. Observations of ‘Driscoll Atlantis’, ‘Biscayne’ and ‘Key Largo’ were taken in side by side comparison in the 2003-2004 winter season. Plants for observation were harvested from McArthur, Calif., and held in refrigerated storage until planting in Hillsborough County, Fla. in October 2003. Plants were grown in raised beds of soil under conditions typical of commercial strawberry production in central Florida. Fruits were harvested twice weekly for yield determination from November 2003 to March 2004. Measurements of plant, flower, and fruit characteristics were made in January 2004, approximately four months after planting. 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. Colors are described and the most similar color designations are provided from The Royal Horticultural Society (R.H.S.) Colour Chart.
6.1 PROPAGATIONThe new variety is principally propagated by way of stolons. Although propagation by stolons is presently preferred, other known methods of propagating strawberry plants may be employed.
6.2 CHARACTERISTICS OF THE NEW VARIETYInformation on the new variety is presented in Tables 1, 2, 3 and 4. In the tables, the flowers described are secondary flowers except where indicated. The fruit described is the secondary fruit on five month old plants. Fruit and flower measurements are an average of both primary and secondary fruit and flowers.
Table 1 provides information on the plant and fruit characteristics of the new variety ‘Driscoll Atlantis’ compared with characteristics of ‘Biscayne’ and ‘Key Largo.’ Table 2 provides additional information of the plant and fruit characteristics of the new variety ‘Driscoll Atlantis’ compared with characteristics of the varieties ‘Biscayne’ and ‘Key Largo.’ Table 3 provides reactions of the new variety to stresses, pests and diseases compared with reactions of the varieties ‘Biscayne’ and ‘Key Largo.’ Table 4 provides isozyme characteristics of the new variety as compared to that of the varieties ‘Biscayne’ and ‘Key Largo.’
In addition to the morphological description above, the new cultivar ‘Driscoll Atlantis’ has been analyzed to obtain an indication of its genetic makeup to provide further means for identifying the new variety and distinguishing it from other somewhat similar and/or related strawberry varieties. Specifically, leaf samples of ‘Driscoll Atlantis’, ‘Biscayne’ and ‘Key Largo’ were analyzed by electrophoresis for isozyme patterns of the enzymes phosphoglucoisomerase (“PGI”), leucine aminopeptidase (“LAP”) and phosphoglucomutase (“PGM”). See J. Amer. Soc. Hort. Sci. 106:684-687. Isozyme characterization of the three varieties is presented in Table 4, with the letters representing the banding patterns for each enzyme as designated in the above-identified article.
