anthocyanin colouration absent to weak, internode length
medium (mean 29.76mm), attitude of distal end pendulous.
Branchlets: angled. Leaf (phyllode): straight, aroma
present, stickiness present in juvenile growth, shape
lanceolate, asymmetric, length medium (mean 86.6mm),
width medium (mean 12.5mm), lateral veins present,
obscure. Inflorescence: shape globular, diameter large
(mean 11.9mm), position on plant axillary, number of heads
per axil one to five, predominant colour red RHS 45B,
Anther: colour yellow RHS 12A. (Note: all RHS colour
chart numbers refer to 1995 edition.)
Origin and Breeding Seedling selection: single seedling
selected from a population of yellow flowering form of
Acacia leprosa. The selected plant was characterised by red
flowers. Selection criteria: red coloured flowers.
Propagation: vegetatively over 6 (six) generations to
confirm stability of the red flowering characteristic.
Breeder: Royal Botanic Gardens Melbourne, Melbourne,
VIC.
Choice of Comparators This is the first variety of the
species and no other variety of common knowledge has
been identified. Therefore, the candidate variety was
compared against the parental material. Two tables are
presented. The first table shows the original colour
distinction with the normally coloured parent; the second
table exhibits proof of breeding over 6 (six) vegetatively
propagated generations.
Comparative Trial Trial 1 was conducted to show the basic
difference in flower colour between the candidate variety
and Acacia leprosa parent. Location: Royal Melbourne
Botanic Gardens, South Yarra, VIC, Aug 1998. Trial 2 was
conducted to show the evidence of breeding over six
generation of selection. Location: Plant Growers Australia,
Park Orchards, VIC, summer 2000 – summer 2001.
Conditions: grown in 20cm pots from 10 tubes randomly
selected from 80 tubes of each variety; in commercial
potting mix in an open all-seasons environment.
Measurements: were taken from 10 plants of each variety of
generations one (1) and six (6).
Prior Applications and Sales
No prior applications. First sold in Australia in Aug 2001.

Application No: 2002/097 Accepted: 5 Jun 2002.
Applicant: Konst Breeding B.V., Nieuwveen, The
Netherlands.
Agent: David Nichols – postal address for the service of
notices on the applicant.
Characteristics (Table 2, Figure 22) Plant: stem length
long, stem thickness thin, density of foliage medium to
dense. Leaf: length medium, width medium to broad, shape
of blade narrow ovate, longitudinal axis of blade straight.
Inflorescence: number of branches in umbel many, length of
branches in umbel short, length of pedicel short. Flower:
main colour red, size medium, spread of tepals medium.
Outer tepal: shape of blade broad obovate, depth of
emargination shallow, stripes on inner side of blade absent,
colour red RHS 45A at the apex, centre and margins and
green white at the base. Inner lateral tepals: shape of blade
elliptic, colour red RHS 45A at the apex, yellow RHS 13A
at the centre and red RHS 47D at the base, number of stripes
few, thickness of stripes small to medium. Inner median
tepal: yellow colour absent, stripes absent. Stamens:
filament colour red, spots absent, anther colour orange.
Pistil: ovary anthocyanin colouration medium, colour of
style red, colour of stigma red, spots on stigma absent.
(Note: all RHS numbers referred to in local observation
were based on the 1986 edition.)
Origin and Breeding Controlled pollination: seed parent
91-141-1 x pollen parent 90-334-2, in a planned breeding
program at the applicant’s research station at Nieuwveen,
The Netherlands. Both parents are non-commercial
varieties within the breeding program. Selection criteria:
from this cross ‘Fuego’ was chosen on the basis of flower
colour and growth habit. Propagation: a number of mature
stock plants were generated from the original seedling by
tissue culture through 10 generations to confirm uniformity
and stability. ‘Fuego’ will be commercially propagated by
tissue culture. Breeder: J.W.M. Konst, Nieuwveen, The
Netherlands.
Choice of Comparators The grouping characteristics used
in identifying the most similar varieties of common
knowledge were – Flower: main colour red and stem length
long. On the basis of these grouping characteristics,
‘Starexan’ A syn Xandra A (PVJ 12:4) was considered as the
most similar variety of common knowledge. Initially
‘Stasach’ A syn Sacha (PVJ 9:3), ‘Miami’ syn Carise Miami
(PVJ 12:2) and ‘Stalona’ A syn Ilona (PVJ 10:4) were also
considered as comparators but were excluded because they
have shorter stems.
Comparative Trial Comparisons of most of the
characteristics are based on Dutch trials, which were
assessed under conditions of controlled environment in
glasshouses. Characteristics of the comparators are derived
from published descriptions in the Plant Varieties Journal.
Detailed flower descriptions of the candidate variety are
based on plants growing in a soil in a multispan polyhouse
at Monbulk, VIC. Flowers from these plants were cut in bud
in April 2002 and transferred to Devon Meadows VIC, and
placed in a solution of 5% sugar and 1 ml/l chlorine bleach.
The flowers were assessed 3 to 4 days later.
