Title: Chrysanthemum plant named ‘Amor Dark Coral’

Description:
Related cultivars: ‘Amor Dark Coral’ is related to ‘Amor Coral’ (U.S. Plant Pat. No. 13,067). ‘Amor Dark Coral’ is a color mutant of ‘Amor Coral’. 
     BACKGROUND OF THE INVENTION 
     ‘Amor Dark Coral’ is a product of a breeding and selection program which had the objective of finding color mutants of ‘Amor Coral’. The new plant of the present invention comprises a new and distinct cultivar of chrysanthemum plant that is a natural occuring sport of a parent chrysanthemum named ‘Amor Coral’ (U.S. Plant Pat. No. 13,067). A comparison with Parent chrysanthemum ‘Amor Coral’ is also made in this application. The new cultivar was discovered as a sport in September 1999 by Rob Noodelijk in a controlled environment (greenhouse) in Rijsenhout Holland. The first act of asexual reproduction of ‘Amor Dark Coral’ was accomplished when vegetative cuttings were taken from the initial selection in October 1999 in Rijsenhout Holland. The new cultivar has been found to retain its distinctive characteristics through successive propagations. 
    
    
     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 petiole and foliage of the new cultivar. 
    
    
     DESCRIPTION OF THE INVENTION 
     This new variety of chrysanthemum is of the botanical classification  Chrysanthemum morifolium . The observations and measurements were gathered from plants grown out door in Rijsenhout, Holland under natural day length and temperature and planted week 22 in 2000 and 2001. The natural blooming date of this crop was September 4-9 (week 36). The average height of the plants was 30-35 CM cms. No growth retardants were used. No tests were done on disease or insects resistance or susceptibility. No tests were done on cold or drought resistance. This new variety produces medium sized blooms with coral ray florets and a dark coral center blooming for a period of 7 weeks. 
     From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Amor Dark Coral’ is ‘Amor Coral’. When ‘Amor Coral’ and ‘Amor Dark Coral’ are being compared the following difference is noticed: The flower color. ‘Amor Dark Coral’ is a color mutant of ‘Amor Coral’ bearing dark coral blooms instead of coral blooms All other characteristics of ‘Amor Coral’ and ‘Amor Dark Coral’ are similar. 
     The following is a description of the plant and characteristics that distinguish ‘Amor Dark Coral’ 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. The color chart used in this description is: The Royal Horticultural Society Colour Chart, edition 1995.
