Description

Botanical designation: Aglaonema hybrida.

Cultivar denomination: ‘MUKCALSUP’.

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 ‘MUKCALSUP’.

The new Aglaonema plant is the product of a controlled breeding program conducted by the Inventor in Tiruporur, Chennai, India. The objective of the breeding program is to create new compact and dense 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 a naturally-occurring branch mutation of Aglaonema hybrida ‘Calypso’, disclosed in U.S. Plant Pat. No. 17,540. The new Aglaonema plant was discovered and selected by the Inventor on Oct. 21, 2011 on a single plant from within a population of plants of ‘Calypso’ in a controlled nursery 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 November, 2011 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 combinations of 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 ‘MUKCALSUP’. These characteristics in combination distinguish ‘MUKCALSUP’ as a new and distinct Aglaonema plant:

    • 1. Upright and outwardly arching plant habit.
    • 2. Freely clumping habit.
    • 3. Vigorous and robust growth habit.
    • 4. Relatively short internodes giving a compact, dense and full plant form.
    • 5. Large dark green-colored leaves with greyed green-colored chevrons, spots and random sectors.
    • 6. Leaf petioles that are green white in color with numerous medium to dark green-colored spots.
    • 7. Relatively tolerant to low temperatures.

Plants of the new Aglaonema differ primarily from plants of the mutation parent, ‘Calypso’, in the following characteristics:

    • 1. Plants of the new Aglaonema are more vigorous, faster-growing and denser and bushier than plants of ‘Calypso’.
    • 2. Plants of the new Aglaonema are more freely clumping than plants of ‘Calypso’.
    • 3. Leaves of plants of the new Aglaonema are more narrow than leaves of plants of ‘Calypso’.
    • 4. Plants of the new Aglaonema and ‘Calypso’ differ in leaf coloration as the upper leaf surfaces of plants of ‘Calypso’ are dark green in color with greyed green-colored chevrons interspersed with distinct golden yellow spots and blotches and the lower leaf surfaces of plants of ‘Calypso’ are pale green in color with ivory white-colored midrib, spots and splashes while the new Aglaonema has leaf coloration of upper surface with dark green-colored leaves with greyed green-colored chevrons, spots and random sectors and lower surface with dark green-colored leaves with green-colored chevrons and spots with light yellow-green-colored random spots.
    • 5. Plants of the new Aglaonema and ‘Calypso’ differ in leaf petiole coloration as leaf petioles of ‘Calypso’ are pale yellow to ivory white in color with sparse and random green-colored spots on the petiole wings while the new Aglaonema has leaf petioles that are green and white in color with numerous medium to dark green-colored spots.

Plants of the new Aglaonema can be compared to plants of Aglaonema crispum ‘B.J. Freeman’, disclosed in U.S. Plant Pat. No. 6,857. In side-by-side comparisons plants of the new Aglaonema differ primarily from plants of ‘B.J. Freeman’ in the following characteristics:

    • 1. Plants of the new Aglaonema are more freely clumping and denser and fuller than plants of ‘B.J. Freeman’.
    • 2. Leaves of plants of the new Aglaonema are more outwardly arching than and not as upright as leaves of plants of ‘B.J. Freeman’.
    • 3. Leaves of plants of the new Aglaonema are smaller than leaves of plants of ‘B.J. Freeman’.
    • 4. Plants of the new Aglaonema and ‘B.J. Freeman’ differ in leaf coloration as leaves of plants of ‘B.J. Freeman’ are dull green in color with dull pale silvery green-colored markings while the new Aglaonema has leaf coloration with dark green-colored leaves with greyed green-colored chevrons, spots and random sectors.
    • 5. Plants of the new Aglaonema and ‘B.J. Freeman’ differ in leaf petiole coloration as leaf petioles of plants of ‘B.J. Freeman’ are solid medium green in color while the new Aglaonema has leaf petioles that are green and white in color with numerous medium to dark green-colored spots.
    • 6. Plants of the new Aglaonema are more low temperature tolerant than plants of ‘B.J. Freeman’.

Plants of the new Aglaonema can also be compared to plants of Aglaonema crispum X Aglaonema treubii ‘Camouflage’, disclosed in U.S. Plant Pat. No. 13,573. In side-by-side comparisons plants of the new Aglaonema differ primarily from plants of ‘Camouflage’ in the following characteristics:

    • 1. Plants of the new Aglaonema are more freely clumping and denser and fuller than plants of ‘Camouflage’.
    • 2. Leaves of plants of the new Aglaonema are more narrow than leaves of plants of ‘Camouflage’.
    • 3. Plants of the new Aglaonema and ‘Camouflage’ differ in leaf coloration as leaves of plants of ‘Camouflage’ are light green in color with contrasting dark and mid-green chevrons, random dark and mid-green spots and flecks and dark green-colored margins while the new Aglaonema has leaf coloration with dark green-colored leaves with greyed green-colored chevrons, spots and random sectors.
