Alstroemeria plant named ‘Tesrobin’

Abstract

A new and distinct cultivar of Alstroemeria plant named ‘Tesrobin’, characterized by its compact and mounding plant habit; sturdy and strong plants; vigorous growth habit; intense red-colored flowers; and good garden performance.

Description

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘Tesrobin’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, grown typically as a potted garden Alstroemeria, and hereinafter referred to by the name ‘Tesrobin’.

The new Alstroemeria is a product of a planned breeding program conducted by the Inventor in De Kwakel, The Netherlands. The objective of the breeding program is to create new potted garden Alstroemeria cultivars that flower continuously and have attractive foliage and flower coloration.

The new Alstroemeria originated from a cross-pollination made by the Inventor in De Kwakel, The Netherlands in May, 2003, of a proprietary Alstroemeria hybrida selection identified as code number E607, not patented, as the female, or seed, parent with a proprietary Alstroemeria hybrida selection identified as code number ZB4061A, not patented, as the male, or pollen, parent. The cultivar Tesrobin was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled environment in De Kwakel, The Netherlands in May, 2004.

Asexual reproduction of the new Alstroemeria by root divisions in a controlled environment in De Kwakel, The Netherlands since the fall of 2004, has shown that the unique features of this new Alstroemeria are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Tesrobin has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Tesrobin’. These characteristics in combination distinguish ‘Tesrobin’ as a new and distinct cultivar of Alstroemeria:

• • 1. Compact and mounding plant habit.
  • 2. Sturdy and strong plants; vigorous growth habit.
  • 3. Intense red-colored flowers.
  • 4. Good garden performance.

Plants of the new Alstroemeria can be compared to plants of the parent selections. Plants of the new Alstroemeria differ from plants of the parent selections primarily in flower color as plants of the parent selections have pink-colored flowers.

Plants of the new Alstroemeria can be compared to plants of the Alstroemeria hybrida cultivar Staprivane, disclosed in U.S. Plant Pat. No. 14,131. Plants of the new Alstroemeria differ primarily from plants of the cultivar Staprivane in flower color as plants of the cultivar Staprivane have purple-colored flowers. In addition, plants of the new Alstroemeria have shorter peduncles than plants of the cultivar Staprivane.

Plants of the new Alstroemeria can also be compared to plants of the Alstroemeria hybrida cultivar Staprioxa, disclosed in U.S. Plant Pat. No. 14,075. Plants of the new Alstroemeria differ primarily from plants of the cultivar Staprioxa in flower color as plants of the cultivar Staprioxa have red purple and yellow-colored flowers. In addition, plants of the new Alstroemeria have shorter and stronger peduncles than plants of the cultivar Staprioxa.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Alstroemeria, 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 Alstroemeria. The photograph comprises a side perspective view of a typical flowering plant of ‘Tesrobin’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants of the new Alstroemeria grown in De Kwakel, The Netherlands during the winter in a glass-covered greenhouse in containers. During the production of the plants, day temperatures averaged 20° C. and night temperatures averaged 14° C. Plants used for the photograph and description were about ten weeks 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.
