‘JAColber’ syn Opening Night<br />
Application No: 1998/076 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 40, Figure 6) Plant: growth habit<br />
narrow, bushy, medium, hybrid tea. Young shoot:<br />
anthocyanin colouration weak, colour reddish brown.<br />
Thorns: short prickles absent, many long prickles, shape<br />
concave. Leaf: size medium, colour dark green. Terminal<br />
leaflet: cross section concave, margin undulation medium,<br />
shape of base obtuse. Flower bud: shape broad ovate.<br />
Flower: double, medium petal number, flower diameter<br />
large, viewed from above irregularly round, side profile<br />
upper flat, side profile lower flattened convex, fragrance<br />
weak. Petal: size very large, middle zone inner side ca RHS<br />
45B, marginal zone inner side ca RHS 45A, middle zone<br />
outer side RHS 53D, marginal zone outer side RHS 53C,<br />
basal spot present, size small, colour RHS 1D, reflexing of<br />
margin medium, undulation 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 />
‘Macauck’ syn Olympiad (US Plant Patent 5519) x<br />
‘Poulman’ syn Ingrid Bergman (US Plant Patent 6264) in a<br />
planned breeding program. The seed parent is a hybrid tea<br />
rose bearing flowers of a brilliant red colouration (RHS<br />
53A). The pollen parent has a significantly shorter plant<br />
habit bearing flowers of a cardinal red colouration (RHS<br />
46A). Selection criteria: seedlings from the cross were<br />
grown and selection was made on the basis of flower<br />
colouration and plant growth habit. Propagation:<br />
vegetatively through many generations. Breeder: Keith W.<br />
Zary, Somis, California. USA.<br />
Choice of Comparators ‘Avon’ and ‘Legend’ were<br />
considered to be the closest comparators for their similarity<br />
in flower colour. The parents were not considered because<br />
of different red colouration as stated above.<br />
Comparative Trial Comparators: ‘Avon’ and ‘Legend’.<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 />
