PLANT VARIETIES JOURNAL 2000 VOL <strong>13</strong> NO. 2<br />
Choice of Comparators ‘Nonya’ A and ‘Krishna’ A were<br />
included in the trial as these are the most similar variety of<br />
common knowledge on the basis of bract colour. ‘Nonya’ A<br />
is also the pollen variety of the candidate variety. The seed<br />
parent ‘White Cascade’ was excluded because of it is<br />
clearly distinguishable white bract colour.<br />
Comparative Trial Comparators: ‘Nonya’ A and<br />
‘Krishna’ A . Location: 50 Sugars Rd, Moggill, QLD, Aug<br />
1999-Apr 2000. Conditions: plants grown in soil-less<br />
potting media in 200mm pots, fertilised with 5g/l<br />
Osmocote® 4-5 month and 9-12 month slow release<br />
fertiliser, grown in full sun. Normal cultural practices with<br />
the exception of pruning were carried out during the trial.<br />
Trial design: 8 plants of each arranged in a completely<br />
randomised design. Measurements: from all trial plants.<br />

Application No: 1999/083 Accepted: 15 Apr 1999.<br />
Applicant: Jan & Peter Iredell, Moggill, QLD.<br />
Characteristics (Table 6, Figure 10) Plant: small to<br />
medium vine with compact bushy habit. Stem: glabrous,<br />
young stems golden green, with axillary thorns. Thorns:<br />
medium long, slightly curved. Leaf: size variable, length<br />
72mm-90mm, width 58mm-68mm, broadly ovate with<br />
acute apex and shortly cuneate base, petioles medium-long,<br />
main colour green (RHS <strong>13</strong>7A) with a yellow green (RHS<br />
147B) irregular central patch. Bract: size medium to large,<br />
rounded, ruffled, initial colour of bract (in full sun) at 8mm<br />
greyed-orange (RHS 165B), bract at 20mm greyed-orange<br />
(RHS 163A), mature bract yellow-orange (RHS 22A) bract<br />
finally greyed-orange (RHS 170B). Flower: cream, stamens<br />
visible, diameter 6mm, floral tube 20mm long, slender,<br />
green-gold. (Note: all RHS colour chart numbers refer to<br />
1986 edition.)<br />
Origin and Breeding Spontaneous mutation: originated as<br />
a bud-sport on Bougainvillea ‘Barleysugar’ at applicant’s<br />
property. The sport was characterised by slightly variegated<br />
leaves whereas in the parental variety such variegation is<br />
absent. The mutated shoot was isolated and propagated<br />
vegetatively through several generations to confirm the<br />
uniformity and stability of the selection. Selection criteria:<br />
compact growth habit, prolific and dense flowering habit,<br />
bract colour. Propagation: by cuttings. Breeder: Jan Iredell,<br />
Moggill, QLD.<br />
Choice of Comparators ‘Barleysugar’ and ‘Golden Tango’<br />
were included in the trial as these are the most similar<br />
variety of common knowledge on the basis of bract colour.<br />
‘Barleysugar’ is also the parental variety from where the<br />
candidate variety was originated.<br />
Comparative Trial Comparators: ‘Barleysugar’, ‘Golden<br />
Tango’. Location: 50 Sugars Rd, Moggill, QLD, Aug 1999-<br />
Apr 2000. Conditions: plants grown in soil-less potting<br />
media in 200mm pots, fertilised with 5g/l Osmocote® 4-5<br />
month and 9-12 month slow release fertiliser, grown in full<br />
sun. Normal cultural practices with the exception of pruning<br />
were carried out during the trial. Trial design: 8 plants of<br />
each arranged in a completely randomised design.<br />
