Abstract

A new and distinct cultivar of Calendula plant named ‘Kercaldiyell’, characterized by its compact, upright to outwardly spreading and mounding plant habit; moderately vigorous growth habit; freely branching habit; freely and continuously flowering habit; long flowering period; large double-type inflorescences with bright yellow-colored ray florets; and good container and landscape performance.

Description

Botanical designation: Calendula hybrida.

Cultivar denomination: ‘KERCALDIYELL’.

BACKGROUND OF THE INVENTION

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

The new Calendula plant is a product of a planned breeding program conducted by the Inventors in Cambridge, United Kingdom. The objective of the breeding program is to create new uniform Calendula plants that flower continuously for a long period of time and have good container and landscape performance.

The new Calendula plant originated from a cross-pollination of a proprietary selection of Calendula hybrida identified as code number 13-5-8, not patented, as the female, or seed, parent with a proprietary selection of Calendula hybrida identified as code number 13-51-7, not patented, as the male, or pollen, parent in 2014. The new Calendula plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Cambridge, United Kingdom in July, 2015.

Asexual reproduction of the new Calendula plant by vegetative tip cuttings in a controlled greenhouse environment in Cambridge, United Kingdom since August, 2015 has shown that the unique features of this new Calendula plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calendula have not been observed under all possible combinations of 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 the new Calendula. These characteristics in combination distinguish ‘Kercaldiyell’ as a new and distinct Calendula plant:

    • 1. Compact, upright to outwardly spreading and mounding plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely and continuously flowering habit.
    • 5. Long flowering period.
    • 6. Large double-type inflorescences with bright yellow-colored ray florets.
    • 7. Good container and landscape performance.

Plants of the new Calendula differ primarily from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Calendula flower earlier in the spring than plants of the female parent selection.
    • 2. Plants of the new Calendula have smaller inflorescences than plants of the female parent selection.
    • 3. Plants of the new Calendula have double-type inflorescences whereas plants of the female parent selection have double and semi-double-type inflorescences.
    • 4. Plants of the new Calendula have not been observed to set seed whereas plants of the female parent selection have abundant seed set.

Plants of the new Calendula differ primarily from plants of the male parent selection in the following characteristics:

    • 1. Plants of the new Calendula are more freely flowering than plants of the male parent selection.
    • 2. Plants of the new Calendula have smaller inflorescences than plants of the male parent selection.
    • 3. Plants of the new Calendula have longer peduncles than plants of the male parent selection.

Plants of the new Calendula also can be compared to plants of Calendula hybrida ‘Kercalsun’, not patented. In side-by-side comparisons, plants of the new Calendula differ primarily from plants of ‘Kercalsun’ in the following characteristics:

    • 1. Plants of the new Calendula are more freely branching than plants of ‘Kercalsun’.
    • 2. Ray florets of plants of the new Calendula are narrower than ray florets of plants of ‘Kercalsun’.
    • 3. Plants of the new Calendula produce more terminal cuttings than plants of ‘Kercalsun’.

Plants of the new Calendula can be compared to plants of Calendula offincinalis ‘Cheers Yellow’, not patented. In side-by-side comparisons, plants of the new Calendula differ primarily from plants of ‘Cheers Yellow’ in the following characteristics:

    • 1. Plants of the new Calendula are more outwardly spreading and mounding than and not as upright as plants of ‘Cheers Yellow’.
    • 2. Plants of the new Calendula and ‘Cheers Yellow’ differ in inflorescence form as plants of ‘Cheers Yellow’ have semi-double and single-type inflorescences.
    • 3. Plants of the new Calendula have been observed to be resistant to Powdery Mildew (Erysiphe and/or Sphaerotheca species) whereas plants of ‘Cheers Yellow’ are not resistant to Powdery Mildew.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Calendula plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calendula plant.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘Kercaldiyell’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Kercaldiyell’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 7.5-liter containers in a glass-covered greenhouse in Cambridge, United Kingdom and under cultural practices typical of commercial Calendula production. Plants were twelve weeks from planting rooted cuttings when the photographs were taken and 16 weeks from planting rooted cuttings when the description was taken.
