Botanical designation: Chrysanthemum×morifolium Ramat.
Cultivar denomination: Zanmustarbu.
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct cultivar of chrysanthemum plant, botanically known as Chrysanthemum×monrifolium Ramat., commercially grown as a garden mum, and herein after referred to by the cultivar denomination ‘Zanmustarbu’. ‘Zanmustarbu’ is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new chrysanthemum cultivars with a double-spider type flower, a natural season flower date around August 20 (week 34); blooming for a period of 5 weeks. ‘Zanmustarbu’ is a seedling resulting from a crossing of the seed parent id 710 and pollen parent 16.590. Plants of the new cultivar ‘Zanmustarbu’ differ from plants of parent plants in (1) flower color (2) and bloom type. (1) The flowers of ‘Zanmustarbu’ are white, while those of the seed parent and pollen parent are yellow, and purple, respectively. (2) The flowers of the seed parent are double, while those of the pollen parent and of ‘Zanmustarbu’ are double-spiders.
The new and distinct cultivar was discovered and selected as a flowering plant by Wilhelmus Bemardus Blom on a cultivated field in Rijsenhout, The Netherlands in 2004. The first act of asexual production of ‘Zanmustarbu’ was accomplished when vegetative cuttings from the initial selection in 2004 were propagated further in a controlled environment in Rijsenhout, The Netherlands. The new cultivar has been found to retain its distinctive characteristics through successive propagations.
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.
The observations and measurements were gathered from plants grown out door in Rijsenhout, The Netherlands under natural day length and temperature and planted in week 25 in 2007. The natural blooming date of this crop was August 20 (week 34). The average height of the plants was 25 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 large sized blooms with white ray florets blooming for a period of 5 weeks.
From the cultivars known to inventor the most similar existing cultivar in comparison to ‘Zanmustarbu’ is ‘Crete’ (U.S. Plant Pat. No. 16,677). When ‘Crete’ and ‘Zanmustarbu’ are being compared the following difference is noticed: The difference of ‘Crete’ and ‘Zarmustarbu’ are (1) Flower type And (2) Flower size. (1) The flowers of ‘Zanmustarbu’ are larger than those of ‘Crete’. (2) The flowers of ‘Zanmustarbu’ are double-spiders, while those of ‘Crete’ are purely double types.
The following is a description of the plant and characteristics that distinguish ‘Zanmustarbu’ 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.
