Botanical designation: Chrysanthemum×morifolium Ramat.
Cultivar denomination: “Zanmuaval Yelimp”.
RELATED CULTIVARS
The new plant is a flower color mutant of ‘Zanmuval’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium Ramat., commercially known as a garden mum, and hereinafter referred to by the cultivar denomination ‘Zanmuaval Yelimp’. ‘Zanmuaval Yelimp’ 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 ‘Zanmuaval (U.S. Plant Pat. No. 22,659). Plants from the new cultivar ‘Zanmuaval Yelimp’ differ from plants of the female parent in the color of the ray-florets. The ray-florets of the parent are purple, while those of the new plant are yellow.
The new cultivar was discovered as a flower color mutant in May 2008 by Henricus Cornelius Maria Jacobs in a controlled environment (greenhouse) in Rijsenhout, the Netherlands. The first act of asexual reproduction of ‘Zanmuaval Yelimp’ was accomplished when after planting of the new plant as a motherplant in July 2008, vegetative cuttings from this Zanmuaval Yelimp 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 propagations.
BRIEF DESCRIPTION OF THE DRAWINGS
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.
FIG. 1 shows a plant of the cultivar in full bloom.
FIG. 2 shows the various stages of blooms of the new cultivar.
FIG. 3 shows the various stages of foliage of the new cultivar.
DESCRIPTION OF THE INVENTION
The observations and measurements were gathered from plants in the period of 21 to 26 weeks of age grown outdoor in Rijsenhout, the Netherlands, under natural day length and temperature and planted in week 23 in 2015. The natural blooming date of this crop was October 19 (week 43). The average height of the plants was 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 greenish center blooming for a period of five weeks.
From the cultivars known to the inventor the most similar existing cultivar in comparison to “Zanmuaval Yelimp” is ‘Zanmuval Golden’ (U.S. Plant Pat. No. 24,024). When ‘Zanmuval Golden’ and “Zanmuaval Yelimp” are being compared the following differences are noticed: The differences of ‘Zanmuval Golden’ and “Zanmuaval Yelimp” are (1). Plant vigor. And (2). Ray-floret color. (1) Plants of ‘Zanmumaval Golden’ are more vigorous than those of ‘Zanmuaval Yelimp’. (2) Ray-florets of ‘Zanmuaval Golden’ are more intensively yellow colored than those of ‘Zanmuaval Yelimp’.
The following is a description of the plant and characteristics that distinguish “Zanmuaval Yelimp” 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 2001.
