Abstract

A new and distinct cultivar of Strawberry plant named ‘LIMVALNERA’, characterized by its upright and semi-open plant habit; moderately vigorous to vigorous growth habit; uniform fruit ripening; large long conical fruits that are glossy and bright red in color with seeds positioned at the fruit surface; pleasant fruit aroma and taste; good fruit postharvest longevity; and good transportation tolerance.

Description

Botanical designation: Fragaria x ananassa.

Cultivar denomination: ‘LIMVALNERA’.

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 ‘LIMVALNERA’ and typically produced for fresh market consumption.

The new Strawberry plant is a product of a planned breeding program conducted by the Inventor in Horst, The Netherlands and Lepe, Spain. The objective of the breeding program was to develop new Strawberry plants with good fruit quality, ease of harvesting, good postharvest longevity and transportation tolerance.

The new Strawberry plant originated from a cross-pollination in March, 2011 in Horst, The Netherlands of Fragaria x ananassa. ‘Primoris’, not patented, as the female, or seed, parent with Fragaria x ananassa ‘Ventana’, disclosed in U.S. Plant Pat. No. 13,469, 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 Lepe, Spain in April, 2012.

Asexual reproduction of the new Strawberry plant by vegetative cuttings (runners) in a controlled environment at Lepe, Spain since May, 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 ‘LIMVALNERA’. These characteristics in combination distinguish ‘LIMVALNERA’ as a new and distinct Strawberry plant:

- 1. Upright and semi-open plant habit.
- 2. Moderately vigorous to vigorous growth habit.
- 3. Uniform fruit ripening.
- 4. Large long conical fruits that are glossy and bright red in color with seeds positioned at the fruit surface.
- 5. Pleasant fruit aroma and taste.
- 6. Good fruit postharvest longevity.
- 7. Good transportation tolerance.

Plants of the new Strawberry differ primarily from plants of the female parent, ‘Primoris’, in the following characteristics:

- 1. Plants of the new Strawberry produce a higher percentage of quality fruits than plants of ‘Primoris’.
- 2. Fruits of plants of the new Strawberry are larger and longer (less rounded) than fruits of plants of ‘Primoris’.
- 3. Fruits of plants of the new Strawberry are darker red in color than fruits of plants of ‘Primoris’.

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

- 1. Plants of the new Strawberry have a semi-open plant habit whereas plants of ‘Ventana’ have an open plant habit.
- 2. Plants of the new Strawberry produce a higher percentage of quality fruits than plants of ‘Ventana’.
- 3. Fruits of plants of the new Strawberry are longer than and not as flat as fruits of plants of ‘Ventana’.

Plants of the new Strawberry can be compared to plants of Fragaria x ananassa ‘Calinda’, disclosed in U.S. Plant Pat. No. 26,904. In side-by-side comparisons, plants of the new Strawberry differ primarily from plants of ‘Calinda’ in the following characteristics:

- 1. Plants of the new Strawberry have a 50% higher fruit yield per plant than plants of ‘Calinda’.
- 2. Fruits of plants of the new Strawberry are longer than fruits of plants of ‘Calinda’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown in 19-cm containers during the summer and early autumn in a polyethylene-covered greenhouse in Horst, The Netherlands and under cultural practices typical of commercial Strawberry production. During the production of the plants, day temperatures ranged from 15° C. to 35° C., night temperatures ranged from 4° C. to 20° C. and light levels ranged from 40 to 110 klux. Plants were one year old when the photographs and description were taken.
