Description

DESCRIPTION OF THE DRAWINGS

[0014] This new strawberry plant is illustrated by the accompanying photographs which show fruit and leaves of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are six months old.

[0015] FIG. 1 illustrates whole fruit of variety DrisStrawFiftyNine.

[0016] FIG. 2A illustrates the upper surface of a leaf of variety DrisStrawFiftyNine. FIG. 2B illustrates the lower surface of a leaf of variety DrisStrawFiftyNine.

DESCRIPTION OF THE NEW VARIETY

[0017] The following detailed descriptions set forth the distinctive characteristics of DrisStrawFiftyNine. The data which define these characteristics is based on observations taken in East Malling, Kent County, the United Kingdom from 2012 to 2016. 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. DrisStrawFiftyNine has not been observed under all possible environmental conditions. The botanical description of DrisStrawFiftyNine was taken from plants that were six months old. The indicated values represent averages calculated from measurements of several plants. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2007 edition). Descriptive terminology follows the Plant Identification Terminology, An Illustrated Glossary, 2.sup.nd edition by James G.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

[0091] DrisStrawFiftyNine differs from the proprietary female parent UUKE 116-003 (unpatented) in that plants of DrisStrawFiftyNine produce higher yields of fruit as compared to plants of UUKE 116-003. Additionally, fruit of DrisStrawFiftyNine are less seedy, larger in size, better in appearance, and have a longer shelf-life as compared to fruit of UUKE 116-003.

[0092] DrisStrawFiftyNine differs from the proprietary male parent UUKE 167-027 (unpatented) in that plants of DrisStrawFiftyNine produce higher yields of fruit as compared to plants of UUKE 167-027. Additionally, fruit of DrisStrawFiftyNine are smaller in size as compared to fruit of UUKE 167-027.

[0093] DrisStrawFiftyNine differs from the commercial variety DrisStrawThirtyFive (U.S. Plant Pat. No. 24,745) in that plants of DrisStrawFiftyNine have an upright growth habit, while plants of DrisStrawThirtyFive have a semi-upright growth habit. Additionally, plants of DrisStrawFiftyNine have medium vigor, while plants of DrisStrawThirtyFive have strong vigor. Moreover, the type of bearing of DrisStrawFiftyNine is fully remontant, while the type of bearing of DrisStrawThirtyFive is not remontant.

[0094] DrisStrawFiftyNine differs from the commercial variety DrisStrawTwo (U.S. Plant Pat. No. 18,878) in that terminal leaflets of DrisStrawFiftyNine have an obtuse shape of base, while terminal leaflets of DrisStrawTwo have a rounded shape of base. Additionally, fruit of DrisStrawFiftyNine have absent or a very narrow width of band without achenes, while fruit of DrisStrawTwo have a medium width of band without achenes. Moreover, fruit of DrisStrawFiftyNine have a calyx attachment that is level with fruit, while fruit of DrisStrawTwo have a calyx attachment that is raised from fruit.
