Description

Botanical designation: Chrysanthemum×morifolium Ramat.

Cultivar denomination: ‘Zanmubrilli’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×morifolium Ramat., and hereinafter referred to by the cultivar denomination ‘Zanmubrilli’. ‘Zanmubrilli’ is a product of a breeding and selection program for pot mums which had the objective of creating new cultivars with a bicolored daisy-type inflorescence, a medium plant height and a response time of 7-8 weeks. ‘Zanmubrilli’ is a seedling resulting from a cross of the female parent id 45626 with the male parent id 53426. Plants of the new cultivar ‘Zanmubrilli’ differ from plants of the female parent in the following characteristics. (1) Color ray-florets. And (2) Vigor. (1) The red color in the ray florets of the female parent is more intense than in those of the seedling. (2) Plants of the female parent are more vigorous than those of the seedling. Plants of the new cultivar ‘Zanmubrilli’ differ from plants of the male parent in vigor; the plants of the male parent are more vigorous than those of the seedling.

The new and distinct cultivar was discovered and selected as a flowering plant within the progeny of the stated cross by Wilhelmus Bernardus Blom in a controlled environment (greenhouse) in Rijsenhout, The Netherlands in April 2004. The first act of asexual production of ‘Zanmubrilli’ was accomplished when vegetative cuttings were used from the initial selection in June 2004 and propagated further in a controlled environment in Rijsenhout, The Netherlands. The new cultivar has been found to retain its distinctive characteristics through successive propagations, although the phenotype may somewhat vary with variations in environment such as light intensity and temperature.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention of a new and distinct variety of chrysanthemum 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 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 in May 2010 from plants grown in a greenhouse in Rijsenhout, The Netherlands, in a photo-periodic controlled crop under conditions generally used in commercial practice. Three cuttings were planted in a pot with a diameter of 12 cm. The greenhouse temperatures for this crop were at day-time 18.degree.C. to 25.degree. C., and at night about 20.degree. C. The photo—periodic response time in this crop was 7.5 weeks after an average of eight long days. After this long day period growth retardants (Alar) were applied six times in an average dose of 1.5 gram/liter water until flowering. The plants were observed (directly) during the flowering of this crop. No tests were done on disease or insect resistance or susceptibility. No tests were done on cold or drought tolerance. To show the phenotype as described ‘Zanmubrilli’ can be planted without assimilation lighting (high pressure sodium lamps) between week 50 and week 40 of the next year under greenhouse conditions in the Netherlands. With assimilation lighting (minimum level 2500 lux) it can be planted all year round under greenhouse conditions in the Netherlands. This new variety produces large sized blooms with red-yellow ray florets and a response time of 7.5 weeks.

From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Zanmubrilli’ is ‘Bajimba’ (U.S. Plant Pat. No. 14,608). When ‘Bajimba’ and ‘Zanmubrilli’ are being compared the following differences are noticed: The differences of ‘Bajimba’ and ‘Zanmubrilli’ are (1) Inflorescence size. And (2) Color pattern ray florets (1) The inflorescences of ‘Bajimba’ are slightly larger than those of ‘Zanmubrilli’. (2) In ‘Bajimba’ the red color covers a larger portion in the ray florets than in ‘Zanmubrilli’.

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