Abstract

A new and distinct variety of strawberry plant named ‘SWTCOL’ particularly characterized by having very large fruit with a conical shape and mid-season harvest maturity, is disclosed.

Description

Genus and species: Fragaria x ananassa Duchesne ex Rozier.

Variety denomination: ‘SWTCOL’.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority from EU Community Plant Variety Rights (CPVO) application no. 2016/2646, filed Oct. 31, 2016, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry variety designated ‘SWTCOL’ and botanically known as Fragaria x ananassa. This new strawberry variety was discovered as a seedling in Cesena, Italy and originated from a controlled cross made in July 2005 in Cesena, Italy between the female parent ‘NF 101’ (unpatented) and the male parent ‘NF 302’ (unpatented). A single plant was selected for asexual propagation via stolons/runners in Cesena, Italy.

The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons.

Plant Breeder's Rights for this variety have been applied for in Europe on Oct. 31, 2016. ‘SWTCOL’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective 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 Sutton Bridge, Lincolnshire, U.K.

• • 1. Very large fruit;
  • 2. Conical shape; and
  • 3. Mid-season harvest maturity.

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 from 10-12 month-old plants.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SWTCOL’. The data which define these characteristics is based on observations taken in Sutton Bridge, Lincolnshire, U.K. 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. ‘SWTCOL’ has not been observed under all possible environmental conditions.

COMPARISON WITH PARENTAL AND SIMILAR COMMERCIAL VARIETIES

The female parent plant of ‘SWTCOL’, cultivar ‘NF 101’ (unpatented), is no longer in existence, so a meaningful comparison cannot be made.

The male parent plant of ‘SWTCOL’, cultivar ‘NF 302’ (unpatented), is no longer in existence, so a meaningful comparison cannot be made.

When ‘SWTCOL’ is compared to the commercial variety ‘Maxim’ (U.S. Plant Pat. No. 5,782), ‘SWTCOL’ has conical shaped fruit, whereas ‘Maxim’ has round fruit.

When ‘SWTCOL’ is compared to the commercial variety ‘Alba’ (unpatented), ‘SWTCOL’ has a mid-season harvest maturity, whereas ‘Alba’ has an early harvest maturity.

When ‘SWTCOL’ is compared to the commercial variety ‘Sweetheart’ (unpatented), ‘SWTCOL’ has very large fruit, whereas ‘Sweetheart’ has medium sized fruit.
