Abstract

A new and distinct cultivar of Leucanthemum plant named ‘Kiedai’, characterized by its upright and compact plant habit; dark green foliage; early and continuous flowering habit; daisy-type inflorescences with; white-colored ray florets and bright yellow-colored disc florets; and good garden performance.

Description

Botanical classification/cultivar designation: Chrysanthemum leucanthemum cultivar Kiedai.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Leucanthemum plant, botanically known as Chrysanthemum leucanthemum and hereinafter referred to by the name ‘Kiedai’.

The new Leucanthemum is a product of a planned breeding program conducted by the Inventor in Steenbergen, The Netherlands. The objective of the breeding program is to create compact Leucanthemum cultivars that flower early and have good garden performance.

The new Leucanthemum originated from a cross-pollination made by the Inventor in the spring of 1995, in Steenbergen, The Netherlands, of a proprietary Chrysanthemum leucanthemum seedling selection identified as code number 92.2006, not patented, as the female, or seed, parent with a proprietary Chrysanthemum leucanthemum seedling selection identified as code number 91.1953, not patented, as the male, or pollen, parent. The new Leucanthemum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Steenbergen, The Netherlands. The selection of this plant was based on its compact plant habit and early flowering.

Asexual reproduction of the new Leucanthemum by vegetative tip cuttings was first conducted in Steenbergen, The Netherlands in 1998. Asexual reproduction by cuttings has shown that the unique features of this new Leucanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Kiedai has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kiedai’. These characteristics in combination distinguish ‘Kiedai’ as a new and distinct Leucanthemum:

• • 1. Upright and compact plant habit.
  • 2. Dark green-colored foliage.
  • 3. Early and continuous flowering habit.
  • 4. Daisy-type inflorescences with white-colored ray florets and bright yellow-colored disc florets.
  • 5. Good garden performance.

Plants of the new Leucanthemum are not as compact and have larger Inflorescences than plants of the female parent selection. Plants of the new Leucanthemum are more compact and have smaller inflorescences than plants of the male parent selection.

Plants of the new Leucanthemum can be compared to plants of the Leucanthemum cultivar Kiemar, disclosed in U.S. Plant Pat. No. 12,978. In side-by-side comparisons conducted by the Inventor in Steenbergen, The Netherlands, plants of the new Leucanthemum differed from plants of the cultivar Kiemar in the following characteristics:

• • 1. Plants of the new Leucanthemum grew faster and stronger than plants of the cultivar Kiemar.
  • 2. Plants of the new Leucanthemum had smaller inflorescences than plants of the cultivar Kiemar.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph at the top of the sheet comprises a close-up view of typical inflorescences and leaves of ‘Kiedai’.

DETAILED BOTANICAL DESCRIPTION

The cultivar Kiedai has 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 aforementioned photographs and following observations, measurements and comparisons describe plants grown in Lompoc, Calif., under commercial practice during the winter in a polycarbonate-covered greenhouse with day temperatures about 18 to 24° C., night temperatures about 16 to 18° C. and light levels about 4,000 to 8,000 foot-candles. Unrooted cuttings were directly planted in 10-cm containers and had been growing for about seven weeks when the photographs and description were taken.
