USPP18000P2 - Strawberry plant named ‘Sonata’ - Google Patents

Abstract

A new and distinct cultivar of Strawberry plant named ‘Sonata’, characterized by its compact growth habit; large and uniformly conical fruits; firm fruits; glossy light red-colored fruits; and pleasant fruit aroma and taste.

Description

Botanical designation: Fragaria L.

Cultivar denomination: ‘Sonata’.

BACKGROUND OF THE INVENTION

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

The new Strawberry is a product of a planned breeding program conducted by the Inventor in Wageningen, The Netherlands. The objective of the breeding program was to develop new high-yielding Strawberry cultivars with good fruit quality, good postharvest longevity and ease of harvesting.

The new Strawberry originated from a cross-pollination made by the Inventor during the summer of 1990 of the Fragaria L. cultivar Elsanta, not patented, as the female, or seed, parent with the Fragaria L. cultivar Polka, not patented, as the male, or pollen, parent. The new Strawberry was discovered and selected by the Inventor from within the resultant progeny from the above-mentioned cross-pollination in a controlled environment in Wageningen, The Netherlands during the summer of 1992.

Asexual reproduction since the fall of 1992 of the new cultivar by cuttings in a controlled environment in Elst, The Netherlands, has shown that the unique features of this new Strawberry are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

• • 1. Compact growth habit.
  • 2. Large and uniformly conical fruits.
  • 3. Firm fruits.
  • 4. Glossy light red-colored fruits.
  • 5. Pleasant fruit aroma and taste.

Plants of the new Strawberry can be compared to plants of the female parent, the cultivar Elsanta. Plants of the new Strawberry differ from plants of the cultivar Elsanta in the following characteristics:

• • 1. Plants of the new Strawberry are more compact than plants of the cultivar Elsanta.
  • 2. Plants of the new Strawberry have smaller flowers than plants of the cultivar Elsanta.
  • 3. Fruits of plants of the new Strawberry are shorter than fruits of plants of the cultivar Elsanta.
  • 4. Fruits of plants of the new Strawberry are light red in color whereas fruits of plants of the cultivar Elsanta are brownish red in color.

Plants of the new Strawberry can be compared to plants of the male parent, the cultivar Polka. Plants of the new Strawberry differ from plants of the cultivar Polka in the following characteristics:

• • 1. Plants of the new Strawberry are more compact than and not as vigorous as plants of the cultivar Polka.
  • 2. Leaves of plants of the new Strawberry are not as rounded as leaves of plants of the cultivar Polka.
  • 3. Fruits of plants of the new Strawberry are larger than fruits of plants of the cultivar Polka.
  • 4. Fruits of plants of the new Strawberry are glossier and lighter red in color than fruits of plants of the cultivar Polka.

Plants of the cultivar Sonata can be compared to the cultivar Gorella, not patented. However, in side-by-side comparisons conducted in Wageningen, The Netherlands, plants of the new Strawberry and the cultivar Gorella differed in the following characteristics:

• • 1. Plants of the new Strawberry were more compact than plants of the cultivar Gorella.
  • 2. Fruits of plants of the new Strawberry were more uniform in shape than fruits of plants of the cultivar Gorella.
  • 3. Fruits of plants of the new Strawberry were glossier than fruits of plants of the cultivar Gorella.
  • 4. Fruits of plants of the new Strawberry were light red in color whereas fruits of plants of the cultivar Gorella were brownish red in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new Strawberry.

The photograph on the first sheet comprises a side view of typical plants of ‘Sonata’ grown in an outdoor nursery.

The photograph on the second sheet is a close-up view of typical fruits of ‘Sonata’.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Sonata have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the aforementioned photograph and following description were grown in an outdoor nursery under conditions that closely approximate commercial production conditions during the spring and summer in Wageningen, The Netherlands. During the production of the plants, day temperatures ranged from 12° C. to 30° C. and night temperatures ranged from 5° C. to 20° C. Plants were about one year old when the photograph and description were taken.
