|||||||||||||||||||||||||||||||||||||
Latin name of the genus and species: Chrysanthemum morifolium.
Variety denomination: `Gedi Two Ylbur`.
The present invention relates to a new and distinct cultivar of garden-type Chrysanthemum plant, herein after referred to by the cultivar name `Gedi Two Ylbur.` The new cultivar is a product of hybridization of a female parent Chrysanthemum plant variety `Dark Veria` (U.S. Plant Pat. No. 10,215) and a male parent Chrysanthemum plant variety `Gedi Two Ylnov` (U.S. Plant Pat. No. 14,414). The new cultivar was discovered and selected by Dirk Pieters in Oostnieuwkerke, Belgium, in September, 1999.
Asexual reproduction of the new cultivar by vegetative cuttings and tissue culture was performed in Staden, Belgium and in Oxnard, Calif., and has shown that the unique features of this cultivar are stable and reproduced true to type on successive generations.
The cultivar `Gedi Two Ylbur` 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.
The following traits have been repeatedly observed and are determined to be the unique characteristics of `Gedi Two Ylbur.` These characteristics in combination distinguish `Gedi Two Ylbur` as a new and distinct Chrysanthemum cultivar:
1. Soft yellow daisy type inflorescence.
2. Naturally blooms in the middle of September.
3. Plant habit of the new variety is exceptional in its round nature.
4. The plant of the new variety has an extremely flexible habit.
Plants of the new cultivar are similar to plants of the female parent variety, `Dark Veria` in most horticultural characteristics, however plants of the new cultivar have a larger diameter inflorescence than plants of the female parent variety. Further, the new variety blooms two weeks later than seed parent. Additionally, the new variety is a daisy-type chrysanthemum, while the seed parent `Dark Veria` is a decorative-type chrysanthemum.
Plants of the new cultivar are similar to plants of the male parent variety, `Gedi Two Ylnov` in most horticultural characteristics, however plants of the new cultivar have a daisy-type inflorescence while the male parent `Gedi Two Ylnov` has a decorative-type inflorescence. Additionally, the new variety naturally blooms two weeks later than plants of `Gedi Two Ylnov.` Further, the new variety has a more flexible plant habit than the male parent variety.
The new cultivar is similar to the commercial variety `Gedi YT8` (U.S. Plant Pat. No. 11,725). In comparison to `Gedi YT8`, the new cultivar `Gedi Two Ylbur` has a sturdier, longer lasting inflorescence which is smaller in diameter. Additionally, the new cultivar is taller and naturally blooms about 2 weeks earlier than `Gedi YT8.`
The photograph shows a plant of `Gedi Two Ylbur.` One cutting was planted in a two-gallon container in May. The plant was grown outdoors in Oxnard, Calif.
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 120 day old plants grown in Oxnard, Calif., during the month of September. Light conditions were bright, and no artificial shading was used. The humidity was low and no rainfall occurred. The growing temperature ranged from approximately 15°C C. to 21°C C. at night, and from approximately 19°C C. to 32°C C., during the day. Measurements and numerical values represent averages of typical flowering types.
