Chrysanthemum plant named `Dark Veria`
A distinct cultivar of Chrysanthemum plant named `Dark Veria`, characterized by its spherical and mounded plant habit; high vigor and moderate growth rate; decorative-type inflorescences with slight open center; bright yellow ray florets; numerous inflorescences per plant; and good garden performance.
The present invention relates to a new and distinct cultivar of garden Chrysanthemum plant, botanically known as Dendranthema grandifiora and referred to by the cultivar name Dark Veria.
The new cultivar is a product of a planned breeding program conducted by the inventor in Staden, Belgium. The objective of the breeding program was to create new garden Chrysanthemum cultivars that are freely branching and have numerous and long-lasting inflorescences.
The new cultivar originated from a cross made by the inventor in 1988 of the nonpatented cultivar Veria as the female, or seed, parent with the nonpatented cultivar Quitpolin as the male, or pollen, parent.
The new Chrysanthemum was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Staden, Belgium.
Asexual reproduction of the new cultivar by terminal cuttings taken at Staden, Belgium, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Dark Veria`. These characteristics in combination distinguish `Dark Veria` as a new and distinct cultivar:
1. Spherical and mounded plant habit, vigorous, moderate growth rate, and freely branching.
2. Decorative-type inflorescences with slight open center.
3. Bright yellow ray florets.
4. Numerous inflorescences per plant.
5. Good garden performance.
The cultivar Dark Veria has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.
In side-by-side comparisons in Staden, Belgium, under commercial practice, plants of the new Chrysanthemum differ from plants of the female parent, the cultivar Veria, in ray floret color and vigor. In the same comparisons, plants of the new Chrysanthemum differ from the male parent, the cultivar Quitpolin, in ray floret color, foliage color, inflorescence size and vigor.
Plants of the new Chrysanthemum can be compared to the cultivar Yellow Triumph (U.S. Plant Pat. No. 7,955). However, in side-by-side comparisons conducted in Oxnard, Calif., under commercial practice, plants of the new Chrysanthemum differed from plants of the cultivar Yellow Triumph in the following characteristics:
1. Plants of the new Chrysanthemum are dense and spherical whereas plants of the cultivar Yellow Triumph are more open and not spherical.
2. Leaves of plants of the new Chrysanthemum have deeper sinuses and more pointed lobes compared to leaves of plants of the cultivar Yellow Triumph.
3. Plants of the new Chrysanthemum are more vigorous than plants of the cultivar Yellow Triumph.
4. Inflorescences of plants of the new Chrysanthemum are smaller but more numerous than inflorescences of plants of the cultivar Yellow Triumph.
5. Plants of the new Chrysanthemum have weaker and shorter peduncles than plants of the cultivar Yellow Triumph.
A detailed comparison of plants of the new Chrysanthemum and the cultivar Yellow Triumph appears in Chart A at the end of the specification.
The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.
The first photograph comprises a side perspective view of a typical flowering 16.5-cm container of `Dark Veria` with five cuttings in the container.
The second photograph comprises a close-up view of five leaves at different stages of development and a fully opened inflorescence. Foliage and floret colors in the photographs may appear different from the actual colors due to light reflectance.
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Oxnard, Calif., under commercial practice in a glass-covered greenhouse with night temperatures ranging between 14 and 20C., day temperatures ranging between 20 and 30C., and average light levels of 5,000 to 6,000 footcandles.
After sticking unrooted cuttings of the new cultivar, plants received 4 weeks of long day/short nights followed by short day/long nights until flowering. Measurements and numerical values represent ranges or averages for six typical flowering plants.
