Anthurium plant named ‘Rijn200002’

Abstract

A new and distinct cultivar of Anthurium plant named ‘Rijn200002’, characterized by its upright and somewhat outwardly spreading plant habit; large, durable and dark green-colored leaves; red-colored spathes with pale yellow-colored spadices that are positioned above and beyond the foliage on strong and erect scapes; freely flowering habit; and good inflorescence longevity.

Description

Botanical classification/cultivar designation: Anthurium andreanum cultivar Rijn200002.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, and hereinafter referred to by the name ‘Rijn200002’.

The new Anthurium is a product of a planned breeding program conducted by the Inventor in Schipluiden, The Netherlands. The objective of the program is to create and develop new freely clumping and freely flowering Anthurium cultivars with strong roots, dark green-colored leaves, attractive spathe color, and good inflorescence longevity.

The new Anthurium originated from a cross by the Inventor on or about Jan. 7, 1998 of a proprietary Anthurium andreanum selection code number 96-003 as the female, or seed, parent with a proprietary Anthurium andreanum selection code number 90-090 as the male, or pollen, parent. The cultivar Rijn200002 was discovered and selected by the Inventor as a plant within the progeny of the stated cross in a controlled environment in De Lier, The Netherlands in January, 2000.

Asexual propagation of the new cultivar by meristem culture in a laboratory in Belgium has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new Anthurium has 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 the cultivar Rijn200002. These characteristics in combination distinguish ‘Rijn200002’ as a new and distinct cultivar:

• • 1. Upright and somewhat outwardly spreading plant habit.
  • 2. Large, durable and dark green-colored leaves.
  • 3. Red-colored spathes with pale yellow-colored spadices that are positioned above and beyond the foliage on strong and erect scapes.
  • 4. Freely flowering habit.
  • 5. Good inflorescence longevity.

Plants of the new Anthurium can be compared to plants of the female parent, the selection 96-003. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Anthurium differed from plants of the selection 96-003 in the following characteristics:

• • 1. Plants of the new Anthurium had much larger leaves than plants of the selection 96-003.
  • 2. Plants of the new Anthurium were bushier than plants of the selection 96-003.
  • 3. Spathe color of plants of the new Anthurium was red whereas spathe color of plants of the selection 96-003 was pink.

Plants of the new Anthurium can be compared to plants of the male parent, the selection 90-090. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Anthurium differed from plants of the selection 90-090 in the following characteristics:

• • 1. Plants of the new Anthurium had more durable leaves than plants of the selection 90-090.
  • 2. Plants of the new Anthurium had larger leaves than plants of the selection 90-090.

Plants of the new Anthurium can also be compared to plants of the cultivar Red King, disclosed in U.S. Plant Pat. No. 13,381. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Anthurium differed from plants of the cultivar Red King in the following characteristics:

• • 1. Plants of the new Anthurium had much larger and darker green-colored leaves than plants of the cultivar Red King.
  • 2. Plants of the new Anthurium had darker red-colored spathes than plants of the cultivar Red King.
  • 3. Spathe color of plants of the new Anthurium developed faster than spathe color of plants of the Red King.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Anthurium, 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 Anthurium.

The photograph comprises a side perspective view of a typical flowering plant of the cultivar Rijn200002 that was about one year-old.
