USPP36925P2 - Cissus plant named ‘G4Y0001’ - Google Patents

Abstract

A new and distinct Cissus plant named ‘G4Y0001’ particularly distinguished by a climbing growth habit suitable for use as a trellised potted plant, yellow-green juvenile foliage with a silvery greyed-green hue over the whole upper leaf surface and an axillary band of greyed-purple in the center, and greyed-green mature foliage on the upper surface that fades to a lighter greyed-green in the center.

Description

Genus and species: Cissus discolor Blume.

Variety denomination: ‘G4Y0001’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Cissus plant, botanically known as Cissus discolor, and hereinafter referred to by the variety name ‘G4Y0001’.

This new Cissus plant was discovered in July 2022 by the inventor as a naturally occurring whole plant mutation (sport) growing amongst the unnamed and unpatented cultivated species of Cissus discolor Blume plants in a greenhouse located in Bogor, Indonesia.

The new cultivar was selected based on its greyed-green leaf color and greyed-purple leaf venation. ‘G4Y0001’ was first reproduced asexually using vegetative meristem tip cuttings in Bogor, Indonesia in September 2022. Asexual propagation by vegetative meristem tip cuttings of the new variety has shown that the unique features of the new variety are stable and reproduced true-to-type to date through eleven successive generations.

Plant Breeder's Rights for this variety have been applied for under CPVO application No. 20/232,571 on Nov. 30, 2023. ‘G4Y0001’ has not been made publicly available or sold anywhere in the world more than one-year prior to the filing date of the present U.S. patent application.

SUMMARY OF THE INVENTION

The new Cissus variety has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, light intensity, water status, fertilizer rate and type, without, however, any variance in genotype.

The following are the most outstanding and distinguishing characteristics of this new Cissus variety. The combination of these characteristics distinguishes ‘G4Y0001’ as a new and distinct variety of Cissus.

• • 1. ‘G4Y0001’ exhibits a climbing growth habit suitable for use as a trellised potted plant;
  • 2. ‘G4Y0001’ exhibits yellow-green juvenile foliage with a silvery greyed-green hue over the whole upper leaf surface and an axillary band of greyed-purple in the center; and
  • 3. ‘G4Y0001’ exhibits greyed-green mature foliage on the upper surface that fades to a lighter greyed-green in the center.

The new Cissus cultivar can be distinguished from its progenitor or parent species Cissus discolor by having mature leaves colored greyed-green with greyed-purple venation on the upper surface, whereas the progenitor or parent species Cissus discolor has mature leaves colored white with green venation on the upper surface.

The new Cissus cultivar can be distinguished from the related known variety of Cissus rhombifolia ‘Mandaiana’ (unpatented) in the following characteristics:

• • 1. ‘GY40001’ has ovate shaped leaves, whereas ‘Mandaiana’ has distinctly tri-lobed, rhomboid shaped leaves that resemble grapevine foliage.
  • 2. ‘GY40001’ has bicolored leaves with a light green base and greyed-purple central coloring along the midrib and leaf margins on the upper surface. In contrast, ‘Mandaiana’ has leaves that are uniformly dark green on the upper surface.
  • 3. ‘GY40001’ has leaves that are greyed-purple on the lower surface, whereas the lower surface of leaves of Mandaiana are typically light green.
  • 4. ‘GY40001’ has a leaf venation that is deeply sunken on the upper surface, contributing to its textured appearance. In contrast, ‘Mandaiana’ has smoother foliage with less prominent venation on the upper leaf surface.
  • 5. ‘GY40001’ has greyed-purple petioles, whereas ‘Mandaiana’ has green petioles.

DESCRIPTION OF THE PHOTOGRAPHS

This new Cissus cultivar is illustrated by the accompanying-colored photographs which show the overall appearance and distinct characteristics of the plant. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 3-month-old plant grown in a 14-centimeter circular container in a greenhouse in Naaldwijk, The Netherlands. Colors in the photographs may differ slightly from the color values cited in the botanical description which accurately describes the colors of the new variety.

DESCRIPTION OF THE NEW VARIETY

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

The following observations and measurements describe plants grown in a conventional greenhouse in Naaldwijk, The Netherlands. Plants were grown under 279-foot candles (3,000 lux) with a daily and nightly temperature range of 12 to 18 degrees Celsius. Detailed descriptions were taken in April 2024 from 3-month-old plants grown in 14-centimeter circular containers. Measurements and numerical values represent averages of typical plant types.
