Fig tree named ‘Violetta’

Abstract

A new and distinct cultivar of Fig tree named ‘Violetta’ characterized by its upright plant habit; rapid growth rate and early fruit production; early ripening; high fruit yield; large and very sweet-tasting fruit with edible sweet, not bitter, skin; and tolerance to low temperatures; typically tolerant to temperatures about −20° C.

Description

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Fig tree, botanically known as Ficus carica, and hereinafter referred to by the cultivar name Violetta.

The new Fig tree is a naturally-occurring whole plant mutation of an unidentified selection of Ficus carica. The new Fig tree was discovered by the Inventor in Haag, Germany in 1983. The new Fig tree was selected based on its extraordinary low temperature tolerance compared to the parent and commercial cultivars of Ficus carica.

Asexual reproduction of the new cultivar by vegetative cuttings taken in Haag, Germany, has shown that the unique features of this new Fig tree are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

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

1. Upright plant habit.

2. Fast growth rate and early fruit production.

3. Early ripening; typically late July to early August in Central Europe.

4. High fruit yield.

5. Large and very sweet-tasting fruit with edible sweet, not bitter, skin.

6. Tolerance to low temperatures; typically tolerant to temperatures about −20° C.

Plants of the new Fig tree can be compared to plants of the nonpatented Ficus carica cultivar Pfalzer Feige. In side-by-side comparisons conducted by the Inventor in Haag, Germany, plants of the new Fig tree developed fruit on younger plants and also produced more fruit per plant than plants of the cultivar Pfalzer Feige.

Plants of the new Fig tree can also be compared to plants of the nonpatented Ficus carica cultivar Italienische Feige. In side-by-side comparisons conducted by the Inventor in Haag, Germany, plants of the new Fig tree developed fruit on younger plants, produced more fruit per plant, and were more winter hardy than plants of the cultivar Pfalzer Feige.

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 more accurately describe the actual colors of the new Fig tree.

The photograph on the first sheet comprises a side perspective view of a typical five year old plant of ‘Violetta’ growing on a trellis.

The photograph on the second sheet comprises a side perspective view of typical young plants of ‘Violetta’ grown in containers; the plant on the right was about two years old and the plant on the left was about one year old.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Violetta have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The following observations, measurements and comparisons describe plants grown in Haag, Germany, in a polyethylene-covered greenhouse with day temperatures ranging from 15 to 30° C. and night temperatures ranging from 10 to 20° C. Plants used for the description ranged from one to about five years old.

In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
