Abutilon plant named ‘Oosttrump’

Abstract

A new and distinct cultivar of Abutilon plant named ‘Oosttrump’, characterized by its compact, upright to outwardly spreading and weeping plant habit; freely branching habit; dark green-colored leaves; freely flowering habit; and pale yellow-colored flowers.

Description

Botanical designation: Abutilon hybrid.

Cultivar denomination: ‘Oosttrump’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Abutilon plant, botanically known as Abutilon hybrid, and hereinafter referred to by the name ‘Oosttrump’.

The new cultivar is a product of a planned breeding program conducted by the Inventor in Venlo, The Netherlands. The objective of the breeding program was to develop new compact Abutilon cultivars with attractive flower coloration.

The new cultivar originated from a cross-pollination made by the Inventor during the summer of 2003 of the Abutilon megabotanicum cultivar Kentisch, not patented, as the female, or seed, parent with an unnamed selection of Abutilon hybrid, not patented, as the male, or pollen, parent. The new cultivar was discovered and selected by the Inventor as a flowering plant within the progeny from this cross-pollination in a controlled environment in Venlo, The Netherlands during the spring of 2004.

Asexual reproduction of the new cultivar by terminal cuttings in De Kwakel, The Netherlands since October, 2004, has shown that the unique features of this new Abutilon are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

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

• • 1. Compact, upright to outwardly spreading and weeping plant habit.
  • 2. Freely branching habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit.
  • 5. Pale yellow-colored flowers.

Plants of the new Abutilon can be compared to plants of the female parent, the cultivar Kentisch. In side-by-side comparisons conducted in Venlo, The Netherlands, plants of the new Abutilon differed from plants of the cultivar Kentisch in the following characteristics:

• • 1. Plants of the new Abutilon were more freely branching than plants of the cultivar Kentisch.
  • 2. Plants of the new Abutilon and the cultivar Kentisch differed in flower color as plants of the cultivar Kentisch had yellow and brown-colored flowers.

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

• • 1. Plants of the new Abutilon were more freely branching than plants of the male parent selection.
  • 2. Plants of the new Abutilon had smaller and more campanulate flowers than plants of the male parent selection.

Plants of the new Abutilon can be compared to plants of the Abutilon cultivar, ‘Julia’, not patented. In side-by-side comparisons conducted in Venlo, The Netherlands, plants of the new Abutilon differed from plants of the cultivar Julia in the following characteristics:

• • 1. Plants of the new Abutilon were more freely branching than plants of the cultivar Julia.
  • 2. Plants of the new Abutilon had smaller leaves than plants of the cultivar Julia.
  • 3. Plants of the new Abutilon had smaller and more campanulate flowers than plants of the cultivar Julia.

Plants used for the aformentioned photographs and following description were about one year old and grown in 10.5-cm containers in a glass-covered greenhouse during the summer in De Kwakel, The Netherlands. During the production of the plants, day temperatures ranged from 18° C. to 27° C. and night temperatures ranged from 12° C. to 22° C. Plants were pinched one time about six to seven weeks after planting.
