Applicant Jan and Peter Iredell, Moggill, QLD. Characteristics (Table 14, Figure 20) Plant: growth habit spreading, size medium. Stem: degree of hairiness absent or low, thorns present, size of thorns large, thickness of thorns thin, shape of thorns flat. New growth: presence of anthocyanin present. Leaf: size medium, length of blade (mean), 79.77 mm, width of blade (mean), 63.36 mm, length of petiole (mean), 24.14 mm, shape broad ovate, shape of apex acuminate, shape of base obtuse, undulation of the margin weak, shape of cross-section concave/flat, curvature of longitudinal axis recurved, glossiness of upper side medium, presence of variegation present, type of variegation central, degree of variegation very low, Leaf colour: number of colours two, primary colour RHS 147A, (most prevalent or obvious) secondary colour RHS 147B, border between colours not clearly defined. Bract: size medium, degree of reflex, medium width medium, shape of apex acute, partly expanded: number of colours one, primary colour 64A, fully expanded: number of colours one, primary colour RHS N66B. Flower: present, diameter small, predominant colour of visible petals (perianth) cream, predominant colour of floral tube purple, size of floral tube medium, shape of floral tube slender, emergence of stamens absent. (Note: all RHS colour chart numbers refer to 2001 edition.) Origin and Breeding Spontaneous mutation: originated as a bud-sport on Bougainvillea ‘Zuki’ A at applicant’s property. The sport was characterised by leaves expressing a very level of variegation when mature, bract colour, prolific flower production and plant vigour. The mutated shoot was isolated and propagated vegetatively through eight generations to confirm the uniformity and stability of the selection. Selection criteria: Bract colour, prolific flower production, plant vigour. Propagation: by cuttings. Breeder: Jan Iredell, Moggill, QLD. Choice of Comparators Grouping characteristics used in identifying the most similar varieties of common knowledge were – Bract colour and plant growth habit. On the basis of these grouping characteristics ‘Zuki’ A , ‘Rubyana’ and ‘Gloucester Royal’ were selected as comparators. ‘Zuki’ A , is also the original parental variety. Comparative Trial Location: Moggill, QLD Dec 2000- May 2002. Conditions: plants raised in soilless potting media in 200mm pots, fertilised with slow release Osmocote® added at 5g/litre, grown under greenhouse film. Normal cultural practices except pruning carried out during the trial. Trial design: 5 plants of each variety randomly placed. Measurements: taken from all plants. Prior Applications and Sales Nil.
