Botanical designation: Chrysanthemum x morifolium Ramat.
Cultivar denomination: ‘Zanmumadore Yellow’.
RELATED CULTIVARSThe new plant is a flower color mutant of ‘Zanmumadore’ (unpatented)
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum x morifolium Ramat, commercially known as a garden mum, and hereinafter referred to by the cultivar denomination ‘Zanmumadore Yellow’. ‘Zanmumadore Yellow’ is a product of a breeding and selection program which had the objective of finding flower color mutants from existing parent plants. The new plant comprises a whole plant mutant of the parent chrysanthemum named ‘Zanmumadore’ (unpatented). Plants from the new cultivar ‘Zanmumadore Yellow’ differ from plants of the parent in the color of the ray-florets. The ray-florets of the parent are pink, while those of the new plant are yellow.
In order to obtain color mutants, unrooted cuttings of the parent plant were irradiated in April 2014 at Ziekenhuis, Rotterdam, the Netherlands, with gamma radiation at a dose of 15Gy. These treated cuttings were then planted in a controlled environment (greenhouse) in Rijsenhout, the Netherlands. In this population of planted cuttings, the new cultivar was discovered as a natural flower color mutant in October 2014 by Sjoukje Heimovaara. The first act of asexual reproduction of ‘Zanmumadore Yellow’ was accomplished when after planting of the ‘Zanmumadore Yellow’ as a motherplant in December 2014, vegetative cuttings from this ‘Zanmumadore Yellow’ were taken and propagated further in Rijsenhout, the Netherlands. In summer, about 6-8 days are needed to initiate roots in cuttings of the new cultivar, after another 5 days rooted plants are formed. The new cultivar has been found to retain its distinctive characteristics through successive asexual propagations.
The present invention of a new and distinct variety of chrysanthemum (of about 22 weeks) is shown in the accompanying drawings, the color being as nearly true as possible with color photographs of this type.
The observations and measurements were gathered from plants in the period of 19 to 25 weeks of age grown outdoors in Rijsenhout, the Netherlands, under natural day length and temperature and planted in week 22 in 2017. The natural blooming date of this crop was October 2 (week 41). The average height of the plants was 25-30 cm. 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 yellow ray florets and a dark center blooming for a period of five weeks.
From the cultivars known to the inventor the most similar existing cultivars in comparison to ‘Zanmumadore Yellow’ is its parent ‘Zanmumadore’ and ‘Zanmumadore Orange’. When ‘Zanmumadore’, ‘Zanmumadore Yellow’ and ‘Zanmumadore Orange’ are being compared the following differences are noticed: ray floret color in ‘Zanmumadore’ is pink, yellow in ‘Zanmumadore Yellow’ and bronze in ‘Zanmumadore Orange’.
The following is a description of the plant and characteristics that distinguish ‘Zanmumadore Yellow’ 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, sixth edition, 2015.
