plant named ‘Duesansugo’

Abstract

A new and distinct cultivar of Sanvitalia plant named ‘Duesansugo’, characterized by its compact and mounding plant habit; vigorous growth habit; early and freely flowering habit; and inflorescences with bright yellow-colored ray florets.

Description

Botanical designation: Sanvitalia procumbens.

Cultivar denomination: ‘DUESANSUGO’.

BACKGROUND OF THE INVENTION

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

The new Sanvitalia plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact and mounding Sanvitalia cultivars with numerous inflorescences.

The new Sanvitalia plant originated from an open-pollination in Rheinberg, Germany in July, 2007, of a proprietary selection of Sanvitalia procumbens identified as code number F-03-21, not patented, as the female, or seed, parent with an unknown selection of Sanvitalia procumbens as the male, or pollen, parent. The new Sanvitalia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2008.

Asexual reproduction of the new Sanvitalia plant by vegetative cuttings in a controlled environment in Rheinberg, Germany since May, 2008, has shown that the unique features of this new Sanvitalia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Sanvitalia have 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 ‘Duesansugo’. These characteristics in combination distinguish ‘Duesansugo’ as a new and distinct cultivar of Sanvitalia:

• • 1. Compact and mounding plant habit.
  • 2. Vigorous growth habit.
  • 3. Early and freely flowering habit.
  • 4. Inflorescences with bright yellow-colored ray florets.

Plants of the new Sanvitalia differ primarily from plants of the female parent selection in plant habit as plants of the new Sanvitalia are more compact than plants of the female parent selection.

Plants of the new Sanvitalia can be compared to plants of Sanvitalia procumbens ‘Aztek Gold’, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Sanvitalia differed from plants of ‘Aztek Gold’ in the following characteristics:

• • 1. Plants of the new Sanvitalia were more compact than plants of ‘Aztek Gold’.
  • 2. Plants of the new Sanvitalia had smaller leaves than plants of ‘Aztek Gold’.
  • 3. Plants of the new Sanvitalia had longer peduncles than plants of ‘Aztek Gold’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Sanvitalia plant. The photograph shows 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 Sanvitalia plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Duesansugo’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 10.5-cm containers during the summer in a glass-covered greenhouse in Rheinberg, Germany under conditions and practices which approximate those generally used in commercial Sanvitalia production. During the production of the plants, day and night temperatures averaged 18° C. and light levels were about 4,500 lux. Plants were pinched one time three weeks after planting. Plants were 20 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
