An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Fresh Forward Holding B.V. of Eck en Wiel, The Netherlands on Mar. 29, 2018, application number 2018/0902. Foreign priority is not claimed to this application.

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Strawberry plant, botanically known as Fragaria x ananassa and hereinafter referred to by the name ‘Verdi’.

The new Strawberry plant is a product of a planned breeding program conducted by the Inventor in Eck en Wiel, The Netherlands. The objective of the breeding program was to develop new Strawberry plants with good fruit quality, ease of harvesting, high yield, large attractive fruits and good postharvest longevity.

The new Strawberry plant originated from a cross-pollination by the Inventor in March, 2011 in Eck en Wiel, The Netherlands of a proprietary selection of Fragaria x ananassa identified as code number E2008-001, not patented, as the female, or seed, parent with a proprietary selection of Fragaria x ananassa identified as code number E2006-367, not patented, as the male, or pollen, parent. The new Strawberry plant was discovered and selected by the Inventor as a single plant from within the progeny of the stated cross-pollination in a controlled environment in Eck en Wiel, The Netherlands in June, 2012.

Asexual reproduction of the new Strawberry plant by runner cuttings in a controlled environment at Eck en Wiel, The Netherlands since July, 2012 has shown that the unique features of this new Strawberry plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Strawberry have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Verdi’. These characteristics in combination distinguish ‘Verdi’ as a new and distinct Strawberry plant:

• • 1. Compact and upright plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Early and uniform fruit ripening.
  • 4. Medium to large-sized conical fruits that are glossy and reddish orange in color.
  • 5. Pleasant fruit aroma and sweet taste.
  • 6. Excellent fruit postharvest longevity.

Plants of the new Strawberry differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Strawberry are more upright than and not as spreading as plants of the female parent selection.
  • 2. Fruits of plants of the new Strawberry are conical in shape whereas fruits of plants of the female parent selection are cylindrical to rhomboid in shape.
  • 3. With relation to their position to the fruits, sepals of plants of the new Strawberry are positioned more horizontal than and not as upright as sepals of plants of the female parent selection.

Plants of the new Strawberry differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Strawberry are more upright than and not as spreading as plants of the male parent selection.
  • 2. Fruits of plants of the new Strawberry are reddish orange in color whereas fruits of plants of the male parent selection are more orange in color.
  • 3. Seeds of plants of the new Strawberry are positioned level with the fruit surface whereas seeds of plants of the male are positioned slightly below the fruit surface.

Plants of the new Strawberry can be compared to plants of Fragaria x ananassa ‘Clery’, not patented. In side-by-side comparisons, plants of the new Strawberry differ primarily from plants of ‘Clery’ in the following characteristics:

• • 1. Plants of the new Strawberry are more upright than and not as spreading as plants of ‘Clery’.
  • 2. Leaves of plants of the new Strawberry are darker green in color than leaves of plants of ‘Clery’.
  • 3. Plants of the new Strawberry have longer trusses than plants of ‘Clery’.
  • 4. Fruits of plants of the new Strawberry are conical in shape whereas fruits of plants of ‘Clery’ are cylindrical to rhomboid in shape.

Plants of the new Strawberry can be compared to plants of Fragaria x ananassa ‘Elsanta’, not patented. In side-by-side comparisons, plants of the new Strawberry differ primarily from plants of ‘Elsanta’ in the following characteristics:

• • 1. Plants of the new Strawberry are more upright than and not as spreading as plants of ‘Elsanta’.
  • 2. Fruits of plants of the new Strawberry are conical in shape whereas fruits of plants of ‘Elsanta’ are cordate in shape.
  • 3. Seeds of plants of the new Strawberry are positioned level with the fruit surface whereas seeds of plants of ‘Elsanta’ are positioned slightly below the fruit surface.

Plants of the new Strawberry can also be compared to plants of Fragaria x ananassa ‘Allegro’, disclosed in U.S. Plant Pat. No. 29,964. In side-by-side comparisons, plants of the new Strawberry differ primarily from plants of ‘Allegro’ in the following characteristics:

• • 1. Plants of the new Strawberry are somewhat less vigorous than plants of ‘Allegro’.
  • 2. Plants of the new Strawberry have slightly larger flowers with broader calyxes than plants of ‘Allegro’.
  • 3. Plants of the new Strawberry produce heavier fruits than plants of ‘Allegro’.
  • 4. The fruit's flesh of plants of the new Strawberry is lighter reddish orange in color than the fruit's flesh of plants of ‘Allegro’.
