Abstract

A new and distinct cultivar of Strawberry plant named ‘Vivaldi’, characterized by its compact and semi-upright plant habit; moderately vigorous to vigorous growth habit; uniform fruit ripening; medium-sized conical fruits that are glossy and bright red in color; pleasant fruit aroma and taste; excellent fruit postharvest longevity; and resistance to Botrytis cinerea and Phytophthora cactorum.

Description

Botanical designation: Fragaria×ananassa.

Cultivar denomination: ‘VIVALDI’.

BACKGROUND OF THE INVENTION

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

The new Strawberry plant is a product of a planned breeding program conducted by the Inventor in Elst, Gelderland, The Netherlands. The objective of the breeding program was to develop new early-ripening Strawberry plants with good fruit quality, ease of harvesting, good postharvest longevity and resistance to pathogens.

The new Strawberry plant originated from a cross-pollination made by the Inventor during the spring of 2003 of a proprietary Strawberry selection identified as code name E1993-053, not patented, as the female, or seed, parent with the Strawberry ‘Sonata’, disclosed in U.S. Plant Pat. No. 18,000, 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 Elst, Gelderland, The Netherlands during the summer of 2005.

Asexual reproduction of the new Strawberry plant by cuttings in a controlled environment at Elst, Gelderland, The Netherlands since the autumn of 2005, 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 ‘Vivaldi’. These characteristics in combination distinguish ‘Vivaldi’ as a new and distinct Strawberry plant:

• • 1. Compact and semi-upright plant habit.
  • 2. Moderately vigorous to vigorous growth habit.
  • 3. Uniform fruit ripening.
  • 4. Medium-sized conical fruits that are glossy and bright red in color.
  • 5. Pleasant fruit aroma and taste.
  • 6. Excellent fruit postharvest longevity.
  • 7. Resistant to Botrytis cinerea and Phytophthora cactorum.

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

• • 1. Fruits of plants of the new Strawberry are conical in shape whereas fruits of plants of the female parent selection are round in shape.
  • 2. Plants of the new Strawberry and the female parent selection differ in fruit color as plants of the female parent selection have darker red-colored fruits.

Plants of the new Strawberry differ from plants of the male parent, ‘Sonata’, in the following characteristics:

• • 1. Plants of the new Strawberry are more upright, more vigorous and larger than plants of ‘Sonata’.
  • 2. Plants of the new Strawberry have larger leaves with three leaflets per leaf whereas plants of ‘Sonata’ have three to five leaflets per leaf.
  • 3. Plants of the new Strawberry flower later than plants of ‘Sonata’.
  • 4. Plants of the new Strawberry and ‘Sonata’ differ in fruit color as plants of ‘Sonata’ produce orange-colored fruits.
  • 5. Fruits of plants of the new Strawberry are firmer than fruits of plants of ‘Sonata’.

Plants of the new Strawberry can be compared to plants of Strawberry ‘Holiday’, not patented. In side-by-side comparisons, plants of the new Strawberry differed primarily from plants of ‘Holiday’ in fruit shape as fruits of plants of ‘Holiday’ were round.

The photograph on the second sheet is a close-up view of typical developing and fully opened flowers of ‘Vivaldi’.

The photograph on the third sheet is a close-up view of typical developing and developed fruits of ‘Vivaldi’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown during the spring and summer in a glass-covered greenhouse in Eck en Wiel, The Netherlands and under cultural practices typical of commercial Strawberry production. During the production of the plants, day temperatures ranged from 12° C. to 23° C. and night temperatures ranged from 8° C. to 12° C. Plants were 2.5 months old when the photographs and description were taken.
