Application No: 2000/068 Accepted: 29 Mar 2000.<br />

Applicant: Ball FloraPlant – A Division of Ball<br />

Horticultural Company, Illinios, USA.<br />

Agent: Oasis Horticulture Pty Ltd, Winmalee, NSW.<br />

Characteristics (Table 19, Figure 20) Plant: height of<br />

foliage medium, width medium. Leaf: length medium,<br />

width medium, shape ovate, blade ground colour of upper<br />

side green with red striations on upper side of petiole,<br />

intensity of ground colour light, blade markings absent,<br />

colour of lower side between veins green. Flower: double,<br />

diameter medium (average 44.3mm), number of colours<br />

one, main colour of upper side of petal red (RHS 44B,<br />

1986), eye zone absent. Time of beginning of flowering:<br />

early.<br />

Origin and Breeding Controlled pollination: seed parent<br />

526-1-1 x pollen parent 3020-3-1-1 in planned breeding<br />

program. Seed parent is characterised by loose growth<br />

habit, semi-double flower form and orange flower colour.<br />

Pollen parent is characterised by loose growth habit, semidouble<br />

flower form and violet flower colour. Selection<br />

criteria: large, floriferous, fully double flowers. Selection<br />

was done at Pan American Seed, Elburn, IL, USA during<br />

1997. Propagation: by vegetative tip cuttings, no off types<br />

occurred in at least three successive vegetative generations<br />

during the selection process and in numerous vegetative<br />

generations since selection. ‘Balfiecobl’ will be<br />

42<br />

commercially propagated by vegetative tip cuttings.<br />

Choice of Comparators ‘Salmon Sunrise’ A syn Fiesta<br />

Salmon Sunrise A and ‘Tropical Orange’ A syn Fiesta<br />

Tropical Orange A were initially considered for the<br />

comparative trial as these are similar varieties of common<br />

knowledge. However, ‘Tropical Orange’ A syn Fiesta<br />

Tropical Orange A was later excluded due to its different<br />

flower colour (RHS 32A). ‘Salmon Sunrise’ A syn Fiesta<br />

Salmon Sunrise A was finally chosen as the sole comparator<br />

for its similar plant habit and flower colour. The parents<br />

were not considered for the trial for the reasons stated<br />

above.<br />

Comparative Trial Location: Winmalee, NSW, Jan – Mar<br />

2001. Conditions: trial conducted in poly house, rooted<br />

cuttings (propagated from stock plants grown at Winmalee)<br />

potted in Jan into 150mm standard pots in commercial<br />

potting mix, nutrients supplied by slow release and liquid<br />

feed fertiliser applications, plant protection treatments<br />

applied as necessary. Trial design: 15 pots of each variety<br />

arranged in a completely randomised design.<br />

Measurements: taken from each plant in the trial.<br />
