Application No: 1998/074 Accepted: 3 Sept 1998.<br />
Applicant: Bear Creek Gardens Inc., Somis, California,<br />
USA.<br />
Agent: Swane Bros. Pty Ltd, Narromine, NSW.<br />
Characteristics (Table 39, Figure 9) Plant: growth habit<br />
bushy, upright, vigorous, hybrid tea. Young shoot:<br />
anthocyanin colouration strong, colour reddish brown.<br />
Thorns: present, shape of lower side flat, many long<br />
prickles, medium short prickles. Leaf size: large, colour<br />
dark green, upper surface medium gloss. Terminal leaflet:<br />
cross section slight concave, margin undulation medium,<br />
rounded base. Flower bud: shape broad ovate. Flower:<br />
double, many petals, flower diameter large, view from<br />
above irregularly round, side profile flattened convex,<br />
fragrance very weak. Septal extensions: absent or very<br />
weak. Petal: size large, middle zone inner side RHS<br />
48B/39B, margin inside RHS 48A/39A, middle zone outer<br />
side RHS 48D/49A, margin outer side RHS 51/50B, basal<br />
spot present, size large, colour RHS 2B, petal margin<br />
undulation medium, reflexing of margin weak. Stamen<br />
filament: colour pink. Flowering habit: remontant. (Note:<br />
all RHS chart numbers refer to 1995 edition.)<br />
Origin and Breeding Controlled pollination: seed parent<br />
‘JACbor’ (US Plant Patent 6,668) x pollen parent ‘JACyo’<br />
(US Plant Patent 6,443) in a planned breeding program. The<br />
seed parent bears large red flowers (RHS 42B-C) and dark<br />
green foliage. The pollen parent has orange-red flower<br />
colour (RHS 32D) with a pale yellow and orange reverse<br />
colour with long flowering stems and has vigorous, upright<br />
growth habit. Selection criteria: seedlings from the cross<br />
were grown and selection was made on the basis of flower<br />
colour, plant growth habit. Propagation: vegetatively<br />
through many generations. Breeder: Keith W. Zary, Somis,<br />
California. USA.<br />
Choice of Comparator Initially ‘Fragrant Cloud’, ‘Lady<br />
Rose’ and ‘Fascination’ considered as comparators. Later<br />
‘Lady Rose’ and ‘Fascination’ was excluded on the basis of<br />
flower colour and shape as well as bush size and foliage<br />
colour and texture. Finally ‘Fragrant Cloud’ was chosen to<br />
be the closest comparator for its similarity in flower colour.<br />
The parents were not considered because of different flower<br />
colour as stated above.<br />
Comparative Trial Comparator ‘Fragrant Cloud’.<br />
Location: Swane’s Nursery, Narromine, NSW in Nov 1999.<br />
Conditions: plant were budded on root stocks and raised in<br />
open beds. Trial Design: completely randomised.<br />
Measurements: from 10 plants taken at random.<br />
