Applicant: Ball FloraPlant – A Division of Ball
Horticultural Company, West Chicago, IL, USA.
Agent: Oasis Horticulture Pty Ltd, Winmalee, NSW.
Characteristics (Table 22, Figure 26) Plant: type perennial,
growth habit prostrate to semi-erect. Stem: anthocyanin
colouration absent, pubescence medium to strong. Leaf:
length medium (mean 66.2mm), width medium (mean
29.7mm), colour of upper side green RHS 137C-B,
anthocyanin colouration absent, shape elliptic, shape of
apex obtuse, shape in cross section concave, pubescence of
upper side very weak, pubescence of lower side very weak,
pubescence of margin very weak. Calyx: length long (mean
22.1mm), width medium (9.3mm), shape obovate, attitude
semi-erect, curving downwards, pubescence medium to
weak, shape of apex obtuse. Flower: type semi-double,
diameter large (67mm), attitude of corolla lobe horizontal,
curving of longitudinal axis upwards, mean length of
peduncle 28.9mm, mean thickness of peduncle 2.4mm.
Corolla lobe: pubescence of inner side absent, pubescence
of outer side very weak, undulation of margin strong, colour
of inner side red-purple ca RHS N74A, colour of outer side
red-purple RHS 77B. Corolla tube: mean diameter 19.8mm.
Style: mean length 13.5mm, colour green. Anther: colour
cream white. (Note: all RHS colour chart numbers refer to
2001 edition.)
Origin and Breeding Controlled pollination: seed parent
proprietary breeding line 3404-4 x pollen parent proprietary
breeding line designated as “double white flowered” in a
planned breeding program in Arroyo Grande, California.
The seed parent is characterised by single flower type. The
pollen parent is characterised by white flower colour.
‘Balrufbrip’ was selected from the seedling progeny of this
cross in Aug 1998 at Arroyo Grande, California, USA.
Selection criteria: plant habit, flower type, flower diameter,
corolla lobe colour, vigour. Propagation: vegetative tip
cuttings. ‘Balrufbrip’ has been found to be uniform and
stable through many generations since selection. Breeder:
Kerry Strope, Ball FloraPlant, Arroyo Grande, California,
USA.
Choice of Comparators Grouping characteristics used in
identifying the most similar varieties of common
knowledge were – Plant: type perennial, Flower: type semidouble,
Corolla lobe: colour of inner side red-purple. On the
basis of these grouping characteristics the following variety
was included in the trial: ‘Adventurer’. For the purpose of
providing evidence of breeding, the parent material can be
clearly distinguished from the candidate variety using the
grouping characteristics stated above.
Comparative Trial Location: Winmalee, NSW, Oct – Dec
2001. Conditions: trial conducted in open production area,
rooted cuttings (propagated from stock plants grown at
Winmalee) potted in Oct into 150mm standard pots in
commercial potting mix, nutrients supplied by slow release
and liquid feed fertiliser applications, plant protection
treatments applied as necessary. Trial design: 15 pots of
each variety arranged in a completely randomised design.
Measurements taken from 10 plants per variety selected at
random (one sample per plant).
