Variety used for comparison: 'Tiger'
Summary: The length of the terminal lobe relative to the leaf length is medium for 'Dekgiliam' while it is medium to long for 'Tiger'. The angle between the primary lateral inflorescence shoot and stem is large for 'Dekgiliam' while it is medium for 'Tiger'. 'Dekgiliam' has a short to medium length peduncle whereas that for 'Tiger' is medium to long.
PLANT: tall to very tall, non-bushy type, response group when grown under precise daylength control is 4 (7 weeks)
PETIOLE: attitude is moderately upwards, short relative to leaf length
LEAF: short to medium length including petiole, medium width, low to medium length/width ratio, terminal lobe is medium length relative to leaf length, lowest lateral sinus is deep, margins of lowest lateral sinus are overlapping, cordate base, absent or very weak glossiness of upper side, dark green on upper side, attitude is horizontal
LEAF MARGIN: medium to many indentations, medium depth indentations
INFLORESCENCE: deeply domed form, narrow to medium width at widest point, large angle between primary lateral shoot and stem, semi-upright attitude of lateral flower heads
FLOWER BUD: colour of outer side just before opening is nearest to grayed-orange (RHS 176A) becoming more yellow in the distal quarter
FLOWER HEAD: few per stem, semi-double type, medium diameter and medium height on non-disbudded plants, few rows of ray florets, medium to many ray florets, short to medium length peduncle
RAY FLORET: ligulate type only, attitude of basal part is moderately ascending to horizontal, ribbed upper surface, very short to short corolla tube, profile in cross-section at widest point is weakly convex, weakly involute margin along basal three quarters, longitudinal axis is reflexed, part of longitudinal axis which is not straight extends from distal quarter to distal half, medium strength curvature along londitudinal axis, short to medium length, medium to broad, low length/width ratio, mamillate tip, one coloured on inner side, main colour on inner side is nearest grayed-orange (RHS 167A, but slightly more yellow), colour of outer and inner sides is similar
DISC: daisy type, medium diameter, medium diameter relative to head diameter, slightly domed profile in cross-section, green before anther dehiscence, no dark spot at centre before anther dehiscence, yellowish green at anther dehiscence
Origin & Breeding History: 'Dekgiliam' was bred and developed as part of a planned breeding program by the breeder, Cornelius W. Dekker, in Hensbroek, Netherlands. It originated from a hybrid cross conducted in September 2007 between the female parent, proprietary seedling number '05.45656.04', and the male parent, proprietary seedling number '05.39660.01'. 'Dekgiliam' was selected from the resultant progeny in March 2008 based on its plant vigour, flower colour, flower number per stem, flowering stem strength and quality.
Tests & Trials: The detailed description of 'Dekgiliam' is based on the UPOV report of Technical Examination, application number 2010/0779, purchased from the Community Plant Variety Office, Angers, France. The trials were conducted by the National Institute of Agricultural Botany in Cambridge, United Kingdom, in 2011. Colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
