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 .
a chrysanthemum plant named ‘ zanmubrilli ’ characterized by its large sized blooms with red - yellow ray florets and prolific branching ; and a response time of 7 . 5 weeks .
