plant name ‘Koncasweet’

Abstract

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

Description

Botanical designation: Alstroemeria hybrida.

Cultivar denomination: ‘KONCASWEET’.

BACKGROUND OF THE INVENTION

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

The new Alstroemeria plant is a product of a planned breeding program conducted by the Inventor in Nieuwveen, The Netherlands. The objective of the breeding program is to create new compact potted garden Alstroemeria plants that flower early and freely with attractive leaf and flower coloration.

The new Alstroemeria plant originated from a cross-pollination made by the Inventor in Nieuwveen, The Netherlands on Jun. 11, 2007 of a proprietary Alstroemeria hybrida selection identified as code number 24096-2, not patented, as the female, or seed, parent with a proprietary Alstroemeria hybrida selection identified as code number 07-0-RD, not patented, as the male, or pollen, parent. The new Alstroemeria plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Nieuwveen, The Netherlands on Sep. 7, 2009.

Asexual reproduction of the new Alstroemeria plant by in vitro rhizogenesis in a controlled greenhouse environment in Nieuwveen, The Netherlands since Sep. 7, 2009 has shown that the unique features of this new Alstroemeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Alstroemeria 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 ‘Koncasweet’. These characteristics in combination distinguish ‘Koncasweet’ as a new and distinct Alstroemeria plant:

• • 1. Compact and mounding plant habit.
  • 2. Sturdy and strong plants.
  • 3. Vigorous growth habit.
  • 4. Freely branching habit.
  • 5. Numerous white and red-colored flowers.
  • 6. Good garden performance.

Plants of the new Alstroemeria can be compared to plants of the female parent selection. Plants of the new Alstroemeria differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Alstroemeria are more compact than plants of the female parent selection.
  • 2. Plants of the new Alstroemeria and the female parent selection differ in flower color as plants of the female parent selection have orange-colored flowers.

Plants of the new Alstroemeria can be compared to plants of the male parent selection. Plants of the new Alstroemeria differ primarily from plants of the male parent selection in flower color.

Plants of the new Alstroemeria can be compared to plants of the Alstroemeria hybrida ‘Koncavanti’, disclosed in U.S. Plant Pat. No. 22,283. In side-by-side comparisons conducted in Nieuwveen, The Netherlands, plants of the new Alstroemeria differed from plants of ‘Koncavanti’ in the following characteristics:

• • 1. Plants of the new Alstroemeria were more compact than plants of ‘Koncavanti’.
  • 2. Plants of the new Alstroemeria had larger flowers than plants of ‘Koncavanti’.
  • 3. Plants of the new Alstroemeria and ‘Koncavanti’ differed in flower color as plants of ‘Koncavanti’ had pink-colored flowers.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants of the new Alstroemeria grown during the spring in 19-cm containers in a glass-covered greenhouse in Nieuwveen, The Netherlands and under cultural practices typical of commercial potted Alstroemeria production. During the production of the plants, day temperatures ranged from 6° C. to 30° C. and night temperatures ranged from 6° C. to 16° C. Plants were 36 weeks old when the photographs and description were taken.
