plant named ‘Mukmina’

Abstract

A new and distinct cultivar of Aglaonema plant named ‘Mukmina’, characterized by its upright and outwardly spreading plant habit; freely clumping habit; vigorous and robust growth habit; relatively short internodes giving a dense and full plant form; large oblong leaves speckled with pale yellow and yellow green-colored random markings with contrasting dark green-colored random markings and margins; dark green-colored petioles; and relative tolerance to low temperatures.

Description

Botanical designation: Aglaonema hybrida.

Cultivar denomination: ‘MUKMINA’.

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 ‘Mukmina’.

The new Aglaonema plant is the product of a controlled breeding program conducted by the Inventor in Chamrajpet, Bangalore, India. The objective of the breeding program is to create new full, dense and compact Aglaonema plants with good plant vigor, interesting and unique leaf shapes and variegation patterns, resistance to pathogens and pests and tolerance to low temperatures.

The new Aglaonema plant is the product of a cross-pollination conducted by the Inventor on Mar. 6, 2004 of Aglaonema hybrida ‘Gold Dust’, disclosed in U.S. Plant Pat. No. 17,497, as the female, or seed, parent with a selection of Aglaonema costatum N.E. Br. var. costatum f. costatum commonly referred to as Spotted Evergreen, not patented, as the male, or pollen, parent. The new Aglaonema plant was discovered and selected by the Inventor in September, 2005 as a single plant from within the resultant progeny of the stated cross-pollination in a controlled environment in Tiruporur, Chennai, India.

Asexual reproduction of the new Aglaonema plant by cuttings and divisions in a controlled environment in Tiruporur, Chennai, India since September, 2005 has shown that the unique features of this new Aglaonema plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Aglaonema have not been observed under all possible 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 ‘Mukmina’. These characteristics in combination distinguish ‘Mukmina’ as a new and distinct Aglaonema plant:

• • 1. Upright and outwardly spreading plant habit.
  • 2. Freely clumping habit.
  • 3. Vigorous and robust growth habit.
  • 4. Relatively short internodes giving a dense and full plant form.
  • 5. Large oblong leaves speckled with pale yellow and yellow green-colored random markings with contrasting dark green-colored random markings and margins.
  • 6. Dark green-colored petioles.
  • 7. Relatively tolerant to low temperatures.

Plants of the new Aglaonema differ from plants of the female parent, ‘Gold Dust’, in the following characteristics:

• • 1. Plants of the new Aglaonema are taller and more vigorous than plants of ‘Gold Dust’.
  • 2. Leaves of plants of the new Aglaonema are larger than and not as flat as leaves of plants of ‘Gold Dust’.
  • 3. Plants of the new Aglaonema and ‘Gold Dust’ differ in leaf coloration, variegation pattern and midvein color.
  • 4. Plants of the new Aglaonema and ‘Gold Dust’ differ in leaf petiole color.

Plants of the new Aglaonema differ from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Aglaonema are more vigorous and more uniform than plants of the male parent selection.
  • 2. Plants of the new Aglaonema have larger leaves than plants of the male parent selection.
  • 3. Plants of the new Aglaonema and the male parent selection differ in leaf shape, coloration, variegation pattern and midvein color.

Plants of the new Aglaonema can be compared to plants of Aglaonema hybrida ‘Emerald Star’, disclosed in U.S. Plant Pat. No. 10,659. In side-by-side comparisons conducted in Chamrajpet, Bangalore, India, plants of the new Aglaonema differed from plants of ‘Emerald Star’ in the following characteristics:

• • 1. Plants of the new Aglaonema had shorter internodes and were denser and fuller than plants of ‘Emerald Star’.
  • 2. Plants of the new Aglaonema and ‘Emerald Star’ differed in leaf shape, coloration and variegation pattern.
  • 3. Plants of the new Aglaonema and ‘Emerald Star’ differed in leaf petiole color.

Plants of the new Aglaonema can also be compared to plants of Aglaonema hybrida ‘Stars’, disclosed in U.S. Plant Pat. No. 10,247. In side-by-side comparisons conducted in Chamrajpet, Bangalore, India, plants of the new Aglaonema differed from plants of ‘Stars’ in the following characteristics:

• • 1. Plants of the new Aglaonema had shorter internodes and were denser and fuller than plants of ‘Stars’.
  • 2. Plants of the new Aglaonema and ‘Stars’ differed in leaf shape, coloration and variegation pattern.
  • 3. Plants of the new Aglaonema and ‘Stars’ differed in leaf petiole color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Aglaonema plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Aglaonema plant. The photograph comprises a side perspective view of a typical plant of ‘Mukmina’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown in 25-cm containers in Miami, Fla. during the summer and autumn in a polypropylene-covered shadehouse. Plants were grown under environmental conditions and cultural practices which approximate those generally used in commercial Aglaonema production. During the production of the plants, day temperatures ranged from 27° C. to 37° C., night temperatures ranged from 15° C. to 26° C. and light levels averaged 1,500 foot-candles. Plants were one year old when the photographs and the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
