Title: Chrysanthemum plant named Hada

Description:
The present invention comprises a new and distinct cultivar of Chrysanthemum, botanically known as Dendranthema grandiflora, and referred to by the cultivar name Hada. 
     Hada, identified as 84125004, was originated from a cross made by Cornelius P. VandenBerg in a controlled breeding program in Salinas, Calif. in 1983. 
     The female parent and the male parent of Hada were both unnamed seedlings, identified respectively as 81822002 and 79C08001. 
     Hada was discovered and selected as one flowering plant within the progeny of the stated cross by Cornelis P. VandenBerg in August 1984 in a controlled environment in Salinas, Calif. 
     The first act of asexual reproduction of Hada was accomplished when vegetative cuttings were taken from the initial selection in October 1984 in a controlled environment in Salinas, Calif., by technicians working under formulations established and supervised by Cornelis P. VandenBerg. 
     Horticultural examination of controlled flowerings of successive plantings has shown that the unique combination of characteristics as herein disclosed for Hada are firmly fixed and are retained through successive generations of asexual reproduction. 
     Hada has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity, and daylength. 
     The following observations, measurements and comparisons describe plants grown in Salinas, Calif. under greenhouse conditions which approximate those generally used in commercial greenhouse practice. The low temperature tolerance was determined in repeated flowerings in Bogota, Colombia. 
     The following traits have been repeatedly observed and are determined to be basic characteristics of Hada, which, in combination, distinguish this Chrysanthemum as a new and distinct cultivar; 
     1. Flat capitulum form. 
     2. Decorative capitulum type. 
     3. Red-purple ray floret color. 
     4. Diameter across face of capitulum up to 62 mm at maturity. 
     5. Uniform eight week photoperiodic flowering response to short days. 
     6. Peduncle length ranging from 10 to 16 cm on open terminal sprays. 
     7. Medium plant height, requiring two long day weeks prior to short days to attain a flowered plant height of 100 to 110 cm for year-round flowerings. 
     8. Excellent tolerance to low temperatures for bud initiation and flower development. 
    
    
     The accompanying photographic drawings show typical inflorescence and leaf characteristics of Hada, with the colors being as nearly true as possible with illustrations of this type. 
     Sheet 1 is a color photograph of Hada grown as a single stem cut spray mum. 
     Sheet 2 is a black and white photograph of three views of the inflorescence of Hada. 
     Sheet 3 is a black and white photograph showing the upper and under sides of the leaves of Hada at three stages of development (mature, intermediate and immature). 
    
    
     Of the commercial cultivars known to the inventor, the most similar in comparison to Hada is Beloved, disclosed in U.S. Plant Pat. No. 3,741. Reference is made to Chart A, which compares certain characteristics of Hada to the same characteristics of Beloved. 
     Similar traits are capitulum form and type, spray formation and plant height. The ray floret color of Beloved is described as lavender; the ray floret color of Hada is red-purple. Hada has a smaller diameter of capitulum, a faster flowering response and a better low temperature tolerance than Beloved. 
     In the following description, color references are made to The Royal Horticultural Society Colour Chart. The color values were determined on plant material grown in Salinas, Calif. on Oct. 8, 1987.
