Abstract: A new and distinct variety of strawberry plant named `DrisStrawThirty` particularly characterized by high yield, dark red fruit color, and large fruit with medium sweetness is disclosed.
Claim: We claim:

1. A new and distinct variety of strawberry plant named `DrisStrawThirty` as described and shown herein.
Description: Genus andspecies: Fragaria.times.ananassa.

Variety denomination: `DrisStrawThirty`.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry variety designated `DrisStrawThirty` and botanically known as Fragaria.times.ananassa. This new strawberry variety was discovered in Avitorejo, Spain in February 2007 and originatedfrom a cross between the proprietary female parent `DrisStrawTwenty` (U.S. Plant Pat. No. 23,383) and the proprietary male parent `197M167` (unpatented). A single plant was selected for asexual propagation via tissue culture and vegetative cuttings inPalencia, Spain in 2007.

`DrisStrawThirty` underwent further testing in Spain for five years (2007-2011). The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons and tissue culture.

Plant Breeder's Rights for this variety have not been applied for. `DrisStrawThirty` has not been made publicly available or sold more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Avitorejo, Spain. 1. High yield; 2. Dark red fruit color; and 3. Large fruit with mediumsweetness.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the new variety at various stages of development. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken fromsix-month-old plants.

FIG. 1 shows overall plant habit including fruit at various stages of development.

FIG. 2 shows upper and lower surfaces of the leaves of the plant with three leaflets.

FIG. 3 shows both upper and lower surfaces of the flowers.

FIG. 4 shows the whole fruit.

FIG. 5 shows the fruit in longitudinal cross-section.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of `DrisStrawThirty`. The data which define these characteristics is based on observations taken in Avitorejo, Spain from 2010 to 2011. This description is inaccordance 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. `DrisStrawThirty` has not been observed under all possible environmental conditions. The botanical description of `DrisStrawThirty` was taken from six-month-old plants. Color references are primarily to The R.H.S. Colour Chart of The RoyalHorticultural 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. Harris and Melinda Woolf Harris, unless where otherwise defined.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

When `DrisStrawThirty` is compared to the proprietary female parent `DrisStrawTwenty` (U.S. Plant Pat. No. 23,383), `DrisStrawThirty` has fruit with dark red skin color, inflorescence positioned level with the foliage, three berries perfruiting truss, and few flowers, whereas `DrisStrawTwenty` has fruit with medium red skin color, inflorescence positioned above the foliage, one berry per fruiting truss, and many flowers. Additionally, `DrisStrawThirty` has a higher fruit yield andgreater individual berry weight than `DrisStrawTwenty`.

When `DrisStrawThirty` is compared to the proprietary male parent `197M167` (unpatented), `DrisStrawThirty` has consistently better shelf life after shipping than `197M167`.

When `DrisStrawThirty` is compared to the commercial variety `DrisStrawEight` (U.S. Plant Pat. No. 20,735), `DrisStrawThirty` has a strong vigor, achenes inserted level with the fruit surface, and is not everbearing, whereas `DrisStrawEight`has a medium vigor, achenes inserted below the fruit surface, and is partially everbearing.

When `DrisStrawThirty` is compared to the commercial variety `DrisStrawSixteen` (U.S. Plant Pat. No. 22,247), `DrisStrawThirty` has no difference or a very slight difference in shape between primary and secondary fruits, a broad band withoutachenes, and is moderately resistant to Powdery Mildew, whereas `DrisStrawSixteen` has a marked difference in shape between primary and secondary fruits, a narrow band without achenes, and is moderately susceptible to Powdery Mildew.
