USPP31130P2 - Chrysanthemum plant named ‘Zanmutumen’ - Google Patents

Abstract

A chrysanthemum plant named ‘Zanmutumen’ characterized by its medium sized two-tone orange blooms with dark centers and prolific branching; natural season flowering date September 10, blooming for a period of 5 weeks.

Description

Botanical designation: Chrysanthemum x morifolium Ramat.

Cultivar denomination: ‘Zanmutumen’.

RELATED CULTIVARS

This new plant cultivar ‘Zanmutumen’ is of the botanical classification Chrysanthemum x morifolium Ramat.

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 ‘Zanmutumen’. ‘Zanmutumen’ is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new cultivars with a double type inflorescence, a natural season flowering date around September 10 (week 37), blooming for a period of 5 weeks. ‘Zanmutumen’ is a seedling resulting from a cross of the female parent 54477 (unpatented) with the male parent 15123 (unpatented). Plants of the new cultivar ‘Zanmutumen’ differ from plants of the female parent in plant shape: plants of the seedling are more round than plants of the female parent, which show a more spreading habit. Plants of the new cultivar ‘Zanmutumen’ differ from plants of the male parent in the following characteristics: (1) Plant shape, and (2) Inflorescence color. (1) Plants of the seedling are more round than plants of the male parent, which are more erect. (2) Inflorescences of the seedling are orange, while those of the male parent are more bronze.

The new and distinct cultivar was discovered and selected as a flowering plant by Sjoukje Heimovaara on a cultivated field in Rijsenhout, The Netherlands in September 2013. The first act of asexual production of ‘Zanmutumen’ was accomplished when vegetative cuttings from the initial selection were propagated further in a controlled environment in October 2013, 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 17 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 new cultivar in full bloom.

FIG. 2 shows the various stages of bloom 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 15 to 21 weeks of age grown outdoor in Rijsenhout, the Netherlands, under natural day length and temperature and planted in week 21 in 2018, receiving drip irrigation. The natural blooming date of this crop was September 10. The average height of the plants was 37 cm. No growth retardants were used. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought tolerance. This new variety produces medium sized two-tone orange blooms with dark centers blooming for a period of 5 weeks.

From the cultivars known to the inventor the most similar existing cultivar in comparison to ‘Zanmutumen’ is ‘Zanmucopper’ (U.S. Plant Pat. No. 29,449). When ‘Zanmucopper’ and ‘Zanmutumen’ are compared the following difference is noticed: plants of ‘Zanmucopper’ flower later in the season than those of ‘Zanmumtumen’.

The following is a description of the plant and characteristics that distinguish ‘Zanmutumen’ 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.
