Description

Latin name of genus and species of plant claimed: Dahlia variabilis.

Variety denomination: ‘Dapared’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Dahlia plant botanically known as Dahlia variabilis and hereinafter referred to by the cultivar name ‘Dapared’.

The new cultivar originated in a controlled breeding program in Rijsenhout, The Netherlands, on Jun. 1, 2000. The objective of the breeding program was the development of freely flowering Dahlia cultivars with large flowers and a compact, and upright growth habit.

The male parent of the new cultivar was the commercially available cultivar Connie, U.S. Plant Pat. No. 6,768. ‘Connie’ is characterized by its red-colored ray florets and compact, upright growth habit. The female parent of the new cultivar was the proprietary breeding selection designated ‘3323’, not patented. ‘3323’ is characterized by its red-colored ray florets, dark green-colored foliage, and compact growth habit. Seed from the above stated cross-pollination was germinated and grown to maturity. One plant within the progeny was discovered and selected by the inventor on Aug. 1, 2001 at Rijsenhout, The Netherlands.

Asexual reproduction of the new cultivar by terminal stem cuttings taken since August 2001 at Rijsenhout, Netherlands and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment such as temperature, light intensity, and day length without, however, any variance in genotype.

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Dapared’ as a new and distinct cultivar of Dahlia plant:

    • 1. Semi-double flower form.
    • 2. Red-colored ray florets and yellow-colored disc florets.
    • 3. Dark green-colored foliage.
    • 4. Compact, upright, and mounded growth habit.

Plants of the new cultivar differ from plants of the male parent primarily in growth habit and from plants of the female parent in flower size and flower color.

Of the many Dahlia cultivars known to the inventor, the most similar to the new cultivar is the male parent ‘Connie’, U.S. Plant Pat. No. 6,768. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Connie’ in the following characteristics:

    • 1. Plants of the new cultivar are more compact than plants of ‘Connie’.
    • 2. Plants of the new cultivar exhibit ray florets of a slightly different color than do plants of ‘Connie’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of the new cultivar. The plants were grown for 11 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color values were determined on Jun. 15, 2005 between 10:00 a.m. and 11:45 a.m. under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings of stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots for 11 weeks while utilizing a soil-less growth medium. Greenhouse temperatures were maintained at approximately 65°-75° F. (18°-24° C.) during the day and approximately 60°-65° F. (15°-18° C.) during the night. Greenhouse light levels were maintained at approximately 4,000-6,000 footcandles during the day. Plants were pinched three weeks after planting of rooted cuttings.
