Citrus plant named ‘Mosquito’

Abstract

A distinct cultivar of Citrus plant named ‘Mosquito’, characterized by its upright and rounded plant form; freely branching growth habit; dark red-colored developing leaves; and green and yellow variegated fully expanded leaves.

Description

Botanical classification/cultivar designation: Citrus aurantifolius cultivar Mosquito

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Citrus plant, botanically known as Citrus aurantifolius, commercially known as Lime, and hereinafter referred to by the name ‘Mosquito’.

The new Citrus was discovered by the Inventor in 1985 in a controlled environment in Boskoop, The Netherlands, as a naturally-occurring whole plant mutation of an unidentified selection of Citrus aurantifolius, not patented. The new Citrus was selected by the Inventor on the basis of its unique dark red-colored developing leaves and green and yellow variegated fully expanded leaves.

Asexual reproduction of the new Citrus by cuttings in a controlled environment in Boskoop, The Netherlands, since 1987, has shown that the unique features of this new Citrus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

1. Upright and rounded plant form.

2. Freely branching growth habit.

3. Dark red-colored developing leaves.

4. Green and yellow variegated fully expanded leaves.

Plants of the cultivar Mosquito differ from the parent selection and other Lime cultivars known to the Inventor in its unique dark red-colored developing leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Citrus, 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 colors of the new Citrus.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Mosquito’ grown in a container. The photograph at the top of the second sheet is a close-up view of typical developing leaves of ‘Mosquito’. The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical fully expanded leaf of ‘Mosquito’.

DETAILED BOTANICAL DESCRIPTION

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 photographs and the following description were about two years old and grown under outdoor field conditions which closely approximate commercial production conditions in Boskoop, The Netherlands. During the production of the plants, day temperatures ranged from 8 to 16° C. and night temperatures ranged from 2 to 8° C. The photographs and description were taken in November, 2002.
