PLANT VARIETIES JOURNAL 2002 VOL <strong>15</strong> NO. 2 colouration absent, shape obovate, shape of apex obtuse, shape in cross section slightly concave, pubescence of upper side medium weak, pubescence of lower side weak, pubescence of margin weak. Calyx: length long (mean 18.3mm), width medium (4.9mm), shape obovate, attitude semi-erect, curving downwards, pubescence medium, shape of apex obtuse. Flower: type semi-double, diameter large (65.1mm), attitude of corolla lobe horizontal, curving of longitudinal axis downwards, mean length of peduncle 28.4mm, mean thickness of peduncle 2.2mm. Corolla lobe: pubescence of inner side absent, pubescence of outer side very weak, undulation of margin strong, colour of inner side purple ca. RHS N78A, colour of outer side red-purple RHS 77A. Corolla tube: mean diameter 14.4mm Style: mean length 11.5mm, colour green. Anther: colour greyed white. (Note: all RHS colour chart numbers refer to 2001 edition.) Origin and Breeding Induced mutation: parent proprietary breeding line designated as “double white flowered” treated with the mutagen colchicine in a planned breeding program in Arroyo Grande, California. The parent is characterised by white flower colour. ‘Balrufpurp’ was selected from a flowering population vegetatively propagated from the treated parent plants in 1998 at Arroyo Grande, California, USA. Selection criteria: plant habit, flower type, flower diameter, corolla lobe colour. Propagation: vegetative tip cuttings. ‘Balrufpurp’ 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’. The variety ‘Traveller’ was initially considered but later excluded as it has darker flower colour. 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 <strong>15</strong>0mm standard pots in commercial potting mix, nutrients supplied by slow release and liquid feed fertiliser applications, plant protection treatments applied as necessary. Trial design: <strong>15</strong> pots of each variety arranged in a completely randomised design. Measurements taken from 10 plants per variety selected at random (one sample per plant).

(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 characterized by white flower colour. ‘Balrufvein’ 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. ‘Balrufvein’ has been found to be uniform and stable through many generations since selection. Breeder: Kerry Strope, Ball FloraPlant, Arroyo Grande, California, USA.
