Origin and Breeding Spontaneous mutation: originated as
a bud-sport on Bougainvillea ‘Jazzi’ A at applicant’s
property. The sport was characterised by variegated leaves
whereas the parental variety lacks such variegation. The
mutated shoot was isolated and propagated vegetatively
through several generations to confirm the uniformity and
stability of the selection. Selection criteria: small compact
growth habit, and variegated foliage. Propagation: by
cuttings. Breeder: Jan Iredell, Moggill, QLD.
Choice of Comparators Grouping characteristics used in
identifying the most similar varieties of common
knowledge were – Leaf variegation, type of variegation, and
plant growth habit. On the basis of these grouping
characteristics ‘Jazzi’ A , ‘Wabag’ and ‘Raspberry Ice’. were
selected as comparators. ‘Jazzi’ 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.
