USPP17432P2 - Aglaonema plant named ‘Indo-Queen’ - Google Patents

Abstract

A new and distinct cultivar of Aglaonema plant named ‘Indo-Queen’, characterized by its upright and outwardly arching plant form; relatively rapid growth rate; freely clumping habit and short internodes; full, dense and bushy appearance; lanceolate leaves with acuminate apices; leaves positioned roughly horizontally to outwardly arching; upper leaf surfaces with light green-colored leaves with scattered dark green-colored spots, splashes and margins; green-colored leaf petioles with sparse and random pale yellow-colored spots and streaks; and tolerance to low temperatures.

Description

Botanical denomination: Aglaonema hybrida.

Cultivar designation: ‘Indo-Queen’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Aglaonema plant, botanically known as Aglaonema hybrida and hereinafter referred to by the name ‘Indo-Queen’.

The new Aglaonema is the result of a planned breeding program conducted by the Inventor in Bangalore, India. The objective of the breeding program is to create new compact Aglaonema cultivars with compact and dense plant habit and unique and attractive leaf coloration.

The new Aglaonema originated from a cross-pollination made by the Inventor in 1990 of the Aglaonema hybrida cultivar Chartreuse Halo, not patented, as the female, or seed, parent with the Aglaonema commutatum cultivar Malay Lady, not patented, as the male, or pollen, parent. The new Aglaonema was discovered and selected by the Inventor in 1991 as a single plant within the progeny of the stated cross-pollination in a controlled environment in Bangalore, India. The new Aglaonema was selected on the basis of its compact plant habit and attractive foliage coloration.

Asexual propagation of the new cultivar by vegetative cuttings since June, 2000 in a controlled environment in Zolfo Springs, Fla., has shown that the unique features of this new Aglaonema 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 ‘Indo-Queen’. These characteristics in combination distinguish ‘Indo-Queen’ as a new and distinct cultivar of Aglaonema:

• • 1. Upright and outwardly arching plant form.
  • 2. Relatively rapid growth rate.
  • 3. Freely clumping habit and short internodes; full, dense and bushy appearance.
  • 4. Lanceolate leaves with acuminate apices.
  • 5. Leaves positioned roughly horizontally to outwardly arching.
  • 6. Attractive leaf coloration; upper leaf surfaces with light green-colored leaves with scattered dark green-colored spots, splashes and margins.
  • 7. Green-colored leaf petioles with sparse and random pale yellow-colored spots and streaks.
  • 8. Tolerant to low temperatures.

In side-by-side comparisons conducted by the Inventor in Bangalore, India, plants of the new Aglaonema differed from plants of the female parent, the Aglaonema hybrida cultivar Chartreuse Halo, in the following characteristics:

• • 1. Plants of the new Aglaonema were more compact than plants of the cultivar Chartreuse Halo.
  • 2. Plants of the new Aglaonema were more freely clumping than plants of the cultivar Chartreuse Halo.
  • 3. Plants of the new Aglaonema has shorter and narrower leaves than plants of the cultivar Chartreuse Halo.
  • 4. Plants of the new Aglaonema and the cultivar Chartreuse Halo differed in leaf coloration as plants of the cultivar Chartreuse Halo had gray-colored leaves with green-colored patches along the midrib and margin.

In side-by-side comparisons conducted by the Inventor in Bangalore, India, plants of the new Aglaonema differed from plants of the male parent, the Aglaonema commutatum cultivar Malay lady, in the following characteristics:

• • 1. Plants of the new Aglaonema were taller than plants of the cultivar Malay Lady.
  • 2. Plants of the new Aglaonema were more freely clumping than plants of the cultivar Malay Lady.
  • 3. Plants of the new Aglaonema had longer and broader leaves than plants of the cultivar Malay Lady.
  • 4. Plants of the new Aglaonema and the cultivar Malay Lady differed in leaf coloration as plants of the cultivar Malay Lady had dark green-colored leaves with irregular gray green-colored bands.

Plants of the new Aglaonema can also be compared to plants of the cultivar Silver Queen, not patented. In side-by-side comparisons conducted in Bangalore, India, plants of the new Aglaonema differed from plants of the Aglaonema cultivar Silver Queen in the following characteristics:

• • 1. Plants of the new Aglaonema grew more rapidly than plants of the cultivar Silver Queen.
  • 2. Plants of the new Aglaonema had larger leaves than plants of the cultivar Silver Queen.
  • 3. Plants of the new Aglaonema and the cultivar Silver Queen differed in leaf coloration as plants of the cultivar Silver Queen were lighter green in color.
  • 4. Plants of the new Aglaonema were more low temperature tolerant than plants of the cultivar Silver Queen.

Plants of the new Aglaonema can also be compared to plants of the cultivar Maria Christina, not patented. In side-by-side comparisons conducted in Bangalore, India, plants of the new Aglaonema differed from plants of the Aglaonema cultivar Maria Christina in the following characteristics:

• • 1. Plants of the new Aglaonema grew more rapidly than plants of the cultivar Maria Christina.
  • 2. Plants of the new Aglaonema were more freely clumping than plants of the cultivar Maria Christina.
  • 3. Plants of the new Aglaonema had larger leaves than plants of the cultivar Maria Christina.
  • 4. Plants of the new Aglaonema and the cultivar Maria Christina differed in leaf coloration as plants of the cultivar Maria Christina were lighter green in color.
  • 5. Plants of the new Aglaonema were more low temperature tolerant than plants of the cultivar Maria Christina.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Indo-Queen 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 aforementioned photographs and following observations and measurements describe plants of the new Aglaonema that were grown in 25-cm containers, in Zolfo Springs, Fla., in a polypropylene-covered shadehouse with light levels about 2,000 to 3,000 foot-candles. During the production of the plants, day temperatures ranged from 23° C. to 35° C. and night temperatures ranged from 16° C. to 26° C. Plants used for the photographs and description were about one year from planting. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
