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 ‘Cadenza’.

The new Strawberry plant is a product of a planned breeding program conducted by the Inventors in Gelderland and Stevensbeek, 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 Inventors in April 2016 in Gelderland, The Netherlands of a proprietary selection of Fragaria x ananassa identified as code number E2012-1189, not patented, as the female, or seed, parent with a proprietary selection of Fragaria x ananassa identified as code number E2008-002, not patented, as the male, or pollen, parent. The new Strawberry plant was discovered and selected by the Inventors as a single plant from within the progeny of the stated cross-pollination in a controlled environment in Stevensbeek, The Netherlands in July 2018.

Asexual reproduction of the new Strawberry plant by runner cuttings in a controlled environment in Gelderland, The Netherlands since September 2018 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 ‘Cadenza’. These characteristics in combination distinguish ‘Cadenza’ as a new and distinct Strawberry plant:

• • 1. Upright plant habit.
  • 2. Vigorous growth habit.
  • 3. Relatively late flowering.
  • 4. Uniform and late season fruit ripening.
  • 5. Large conical fruits that are glossy and reddish orange in color.
  • 6. Pleasant fruit aroma and slightly sweet/sour taste.
  • 7. Excellent fruit postharvest longevity.

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

• • 1. Leaves of plants of the new Strawberry are lighter green in color than leaves of the female parent selection.
  • 2. Plants of the new Strawberry flower later than plants of the female parent selection.
  • 3. Fruits of plants of the new Strawberry are conical in shape whereas fruits of plants of the female parent selection are cordate in shape.

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 not as dense as plants of the male parent selection.
  • 2. Flowers of plants of the new Strawberry are positioned at or about the foliar plane whereas flowers of plants of the male parent selection are positioned below the foliar plane.
  • 3. Plants of the new Strawberry flower slightly earlier than plants of the male parent selection.

Plants of the new Strawberry can be compared to plants of Fragaria x ananassa ‘Ravellia’, disclosed in U.S. Plant Pat. No. 36,421. In side-by-side comparisons, plants of the new Strawberry differ primarily from plants of ‘Ravellia’ in the following characteristics:

• • 1. Plants of the new Strawberry flower and produce fruit later than plants of ‘Ravellia’.
  • 2. Fruits of plants of the new Strawberry are orangish red in color whereas fruits of plants of ‘Ravellia’ are bright red in color.

Plants of the new Strawberry can be compared to plants of Fragaria x ananassa ‘Vivaldi’, disclosed in U.S. Plant Pat. No. 26,873. In side-by-side comparisons, plants of the new Strawberry differ primarily from plants of ‘Vivaldi’ in the following characteristics:

• • 1. Plants of the new Strawberry are taller and more upright than plants of ‘Vivaldi’.
  • 2. Plants of the new Strawberry flower and produce fruit later than plants of ‘Vivaldi’.
  • 3. Fruits of plants of the new Strawberry are reddish orange in color whereas fruits of plants of ‘Vivaldi’ are bright red in color.

Plants of the new Strawberry can also be compared to plants of Fragaria x ananassa ‘Malwina’, disclosed in U.S. Plant Pat. No. 23,246. In side-by-side comparisons, plants of the new Strawberry differ primarily from plants of ‘Malwina’ in the following characteristics:

• • 1. Plants of the new Strawberry are not as dense as plants of ‘Malwina’.
  • 2. Flowers of plants of the new Strawberry are positioned at or about the foliar plane whereas flowers of plants of ‘Malwina’ are positioned below the foliar plane.
  • 3. Plants of the new Strawberry flower slightly earlier than plants of ‘Malwina’.
