RELATED CULTIVARS
‘Sizzleness Purple’ is related to ‘Sizzleness’ (U.S. Plant patent application Ser. No. 10/782,856), of which plant it is a color sport.
BACKGROUND OF THE INVENTION
‘Sizzleness Purple’ is a product of a breeding and selection program which had the objective of finding color mutants of ‘Sizzleness’. The new plant of the present invention comprises a new and distinct cultivar of chrysanthemum plant that is a natural occurring sport of a parent chrysanthemum named ‘Sizzleness’. A comparison with parent chrysanthemum ‘Sizzleness’ is also made in this application. The new cultivar was discovered as a sport in 2002 by Mark Roland Boeder in a controlled environment (greenhouse) in Rijsenhout, Holland. The first act of asexual reproduction of ‘Sizzleness Purple’ was accomplished when vegetative cuttings were from the initial selection in 2002 in Rijsenhout, Holland.
SUMMARY OF THE INVENTION
The present invention is a new and distinct variety of chrysanthemum bearing medium sized decorative blooms with elongated quilled purple ray-florets and a green center.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention of a new and distinct variety of chrysanthemum is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.
FIG. 1 shows a plant of the cultivar in full bloom.
FIG. 2 shows the various stages of bloom of the new cultivar.
FIG. 3 shows the foliage of the new cultivar.
DESCRIPTION OF THE INVENTION
This new variety of chrysanthemum is of the botanical classification Chrysanthemum morifolium L. The observations and measurements were gathered from plants grown in April/May in a greenhouse in Rijsenhout Holland in a photo-periodic controlled crop under conditions generally used in commercial practice. The greenhouse temperatures during this crop were at day-time between 18° C. and 25° C. and at night 20° C. After a long day period of 14 days the photo-periodic response time in this crop was 52 days. After the long day period to flowering growth retardants were applied 2 to 3 times in an average dose of 2.5 gram/liter water. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought resistance. This new variety produces medium sized blooms with purple ray-florets and blooming on the plant for 5 weeks. This new variety of chrysanthemum has been found to retain its distinctive characteristics throughout successive propagations however the phenotype may vary significantly with variations in environment such as light intensity and temperature. To show the phenotype as described ‘Sizzleness Purple’ can be planted without assimilation lightning (high pressure sodium lamps) between week 1 and week 35 year under greenhouse conditions in Holland. With assimilation light (minimum level 2500 lux) it can be planted year round under greenhouse conditions in Holland.
From the cultivars known to inventor the most similar existing cultivars in comparison to ‘Sizzleness Purple’ is the parent ‘Sizzleness’ and its sports ‘Sizzleness Pink’ (U.S. Plant Pat. No. 15,504), and ‘Sizzleness Salmon’ (U.S. Plant patent application Ser. No. 10/979,188). When ‘Sizzleness Purple’, ‘Sizzleness Pink’, ‘Sizzleness Salmon’ and the parent ‘Sizzleness’ are being compared the following differences and similarities are noticed: The difference of ‘Sizzleness’ and its sports ‘Sizzleness Purple’, ‘Sizzleness Pink’ and ‘Sizzleness Salmon’ is (1) Color ray florets. The color is for ‘Sizzleness’ purple and cream, while it is purple for ‘Sizzleness Purple’, pink for ‘Sizzleness Pink’, and dark salmon for ‘Sizzleness Salmon’. For which charecteristic ‘Sizzleness Purple’ has been selected from the original ‘Sizzleness’. All other characteristics of ‘Sizzleness’ and ‘Sizzleness Purple’ are similar.
The following is a description of the plant and characteristics that distinguish ‘Sizzleness Purple’ as a new and distinct variety. The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designations and the colors depicted in the photographs are due to photographic tolerances.
