Abstract

A chrysanthemum plant named ‘Zanmumajes’ characterized by its small sized blooms with red-purple ray florets and prolific branching; natural season flowering date October 2 (week 40); blooming for a period of five weeks.

Description

Botanical designation: Chrysanthemum x morifolium Ramat.

Cultivar denomination: ‘Zanmumajes Red’.

RELATED CULTIVARS

The new plant is a flower color mutant of ‘Zanmumajes’ (U.S. Plant Pat. No. 26,847)

BACKGROUND OF THE INVENTION

The 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 ‘Zanmumajes Red’. ‘Zanmumajes Red’ 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 ‘Zanmumajes’ (U.S. Plant Pat. No. 26,847). A comparison between the parent and ‘Zanmumajas Red’ is provided in the section description of the invention.

In order to obtain flower color mutants, unrooted cuttings of the parent plant were irradiated in April 2013 at Ziekenhuis, Rotterdam, the Netherlands, with gamma radiation at a dose of 15 Gy. 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 flower color mutant in October 2013 by Sjoukje Heimovaara in a controlled environment (greenhouse) in Rijsenhout, the Netherlands. The first act of asexual reproduction of ‘Zanmumajes Red’ was accomplished when after planting of the ‘Zanmumajes Red’ as a motherplant in December 2013, vegetative cuttings from this ‘Zanmumajes Red’ 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 19 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 16 to 23 weeks of age grown outdoor in Rijsenhout, the Netherlands, under natural day length and temperature and planted in week 23. The natural blooming date of this crop was October 2 (week 40). The average height of the plants was 35-40 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 small sized blooms with red-purple ray florets blooming for a period of five weeks.

From the cultivars known to the inventor the most similar existing cultivar in comparison to ‘Zanmumajes Red’ is ‘Zanmumajes’. When ‘Zanmumajes’ and ‘Zanmumajes Red’ are being compared the following differences are noticed: (1) Color ray florets. And (2) Presence disc florets. (1) Ray florets of ‘Zanmumajes’ are purple, while those of ‘Zanmumajes Red’ are more reddish purple. (2) Disc florets are lacking in ‘Zanmumajes’ and some disc florets are formed in ‘Zamumajes Red’, especially when grown indoor.

The following is a description of the plant and characteristics that distinguish ‘Zanmumajes Red’ 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).
