Abstract

A distinct cultivar of Chrysanthemum plant named `Tripoli`, characterized by its spherical and rounded plant habit; moderate growth rate and vigorous; multiple secondary laterals and numerous leaves; daisy-type inflorescences; purple ray florets with bright yellow disc florets; freely flowering; and good garden performance.

Description

The present invention relates to a new and distinct cultivar of garden Chrysanthemum plant, botanically known as Dendranthema grandiflora and referred to by the cultivar name `Tripoli`.
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 of the nonpatented cultivar `Quick Marie` as the female, or seed, parent with the nonpatented cultivar `Prisma` 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 `Tripoli`. These characteristics in combination distinguish `Tripoli` as a new and distinct cultivar:
1. Spherical and rounded plant habit, moderate growth rate and vigorous.
2. Freely branching with secondary laterals and numerous leaves gives full, bushy appearance.
3. Daisy-type inflorescences.
4. Purple ray florets with bright yellow disc florets.
5. Freely flowering.
6. Good garden performance.
The cultivar `Tripoli` 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 `Quick Marie`, in plant size and inflorescence form and size. In the same comparisons, plants of the new Chrysanthemum differ from the male parent, the cultivar `Prisma`, in ray floret color, inflorescence form and plant size.
Plants of the new Chrysanthemum can be compared to the cultivar `Stargazer` (U.S. Plant Pat. No. 5,695). However, in side-by-side comparisons conducted in Oxnard, Calif., under commercial practice, plants of the new Chrysanthemum differed from plants of the cultivar `Stargazer` in the following characteristics:
1. Plants of the new Chrysanthemum are full, spherical and rounded whereas plants of the cultivar `Stargazer` are upright.
2. Plants of the new Chrysanthemum are shorter than plants of the cultivar `Stargazer`.
3. Plants of the new Chrysanthemum are more freely branching than plants of the cultivar `Stargazer`. In addition, plants of the new Chrysanthemum have numerous secondary lateral branches.
4. Leaves of plants of the new Chrysanthemum are shorter but more numerous than leaves of plants of the cultivar `Stargazer`.
5. Inflorescences of plants of the new Chrysanthemum are smaller, flatter and have fewer ray florets but are more numerous than inflorescences of plants of the cultivar `Stargazer`.
6. Plants of the new Chrysanthemum have weaker and shorter peduncles than plants of the cultivar `Stargazer`.
A detailed comparison of plants of the new Chrysanthemum and the cultivar `Stargazer` 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 `Tripoli` with five cuttings in the container.
The second photograph comprises a close-up view of 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.
