PLANT VARIETIES JOURNAL 2000 VOL 13 NO. 1
Stem: anthocyanin colouration of stem dark (RHS 59A),
abundant branching. Leaf blade: ground colour of upper
side dark green, anthocyanin colour concentration in petiole
dark (RHS 59A-60A). Inflorescence: number of flowers per
axil 2-7. Flower: size medium, number of colours (eye zone
excluded) one, main colour of upper side of petal red (RHS
53A), eye zone absent, main colour of under side of petal
red (RHS 47B) colour of spur red-purple (RHS 59A),
anther colour red. (Note: all RHS colour chart numbers
refer to 1986 edition.)
Origin and Breeding Controlled pollination: seed parent
S269 x pollen parent S015 in a planned breeding program.
The seed parent was characterised by good flower stability,
mid to late season flowering time. The pollen parent was
characterised by medium to strong vigour, bluish red flower
colour. Hybridisation took place in Rheinberg, Germany pre
1996. Selection criteria: early flowering, very good flower
stability, vigour. Propagation: a number of mature stock
plants were generated from this seedling through cuttings
and found to be uniform and stable. ‘Dueimpetred’ will be
commercially propagated by vegetative cuttings from stock
plants. Breeder: Marga Dummen, Rheinberg, Germany.
Choice of Comparators ‘Paradise Moala’ and ‘Paradise
Prepona’ were considered for the comparative trial as the
most similar varieties of common knowledge. The Red Fox
Riviera series varieties are similar to the Paradise series
varieties in flower size, number, colour and earliness. All
other varieties available in Australia were excluded because
of their lack of similarity to either of the above series
varieties.
Comparative Trial Comparators: ‘Paradise Moala’,
‘Paradise Prepona’. Location: trials conducted at F&I
Baguley Flower and Plant Growers, Clayton South, VIC,
Aug-Dec 1999. Conditions: plants raised on their own roots
from cuttings planted into 150mm pots in commercial pine
bark potting mix on raised glasshouse benches. Pots were
watered and fed using a drip system (one dripper/pot). The
glasshouse walls and roof were sprayed with whitewash at
the start of the trial. All plants were subjected to the same
spray chemical treatments to maintain health. Trial design:
12 plants of each variety were arranged in rows.
Measurements: from all trial plants.

Characteristics (Table 24, Figure 30) Plant: habit
spreading, height tall, width medium-broad, early
flowering. Stem: anthocyanin colouration of stem greybrown
(RHS 199B), abundant branching. Leaf blade:
ground colour of upper side dark green (RHS 139A)
anthocyanin colour concentration in petiole light.
Inflorescence: number of flowers per axil 2-7. Flower:
number of colours (eye zone excluded) one, main colour of
upper side of petal dark red-purple (RHS 74A-B), eye zone
present, size of eye zone small, colour of eye zone solid
dark red purple (RHS 74A), colour of spur red purple (RHS
58A), anther colour red purple (RHS 57B). (Note: all RHS
colour chart numbers refer to 1986 edition.)
Origin and Breeding Controlled pollination: seed parent
K2OP x pollen parent D5 in a planned breeding program.
The seed parent was characterised by more magenta (red) in
flower colour with less branching and not as compact as
‘Dueribluni’. The pollen parent was characterised by green
foliage and more compact growth habit. Hybridisation took
place in Rheinberg, Germany pre 1998. Selection criteria:
blue flowers, dark foliage. Propagation: a number of mature
stock plants were generated from this seedling through
cuttings and found to be uniform and stable. ‘Dueribluni’
