Application No: 1994/204 Accepted: 12 Oct 1994.
Applicant: Mrs H M Barclay, Findon, SA.
Agent: Homewood Asset Pty Ltd, Waterloo Corner, SA.
Characteristics (Table 35, Figure 17) Plant: habit bushy,
height short to medium, width medium. Young shoot:
anthocyanin strong reddish brown to purple. Thorns:
present, shape of lower side concave, few short thorns,
medium number long thorns (mean length 4.2mm). Leaf:
size large, colour medium, glossiness weak, cross section
slight convex, medium undulation of margin. Terminal
leaflet: length medium (mean 50.0mm), width medium
(mean 34.3mm), shape of base rounded, petiole length
medium (mean 21.2mm). Flowering shoot: number of
flowers medium. Flower pedicel: hairs or thorns few.
Flower bud: shape ovate. Flower: type double, petal number
many, colour pink, diameter medium (mean 86.5mm),
viewed from above irregularly rounded, upper and lower
profile flat, fragrance weak. Sepal: extensions weak (length
mean 36.8mm). Petal: size medium, colour of inner and
outer side of midzone RHS 54D-55D, colour of inner and
outer side of margin RHS 55C, basal spot present on inner
side (RHS 4C) and outer side (RHS 9D), size small,
reflexing of margin medium, undulation of margin weak;
stamen filament colour pink; seed vessel size small, pitcher
shaped; flowering habit almost continuous, time of
beginning of flowering medium. (Note All RHS chart
numbers refer to 1986 edition).
Origin and Breeding Seedling selection: open pollinated
seedling selected from a rose bed between varieties ‘First
Love’ and ‘Roundelay’ at applicant’s property in Findon,
SA. ‘First Love’ is a hybrid tea with large light pink flowers,
where as ‘Roundelay’ is also a hybrid tea but with dark red
flowers. The seedling was characterised by unique flower
colour, deep pink centre with dark pink streaks present on
the petals, which is quite distinct from the above varieties.
Cuttings were taken from the seedling and propagated
through five generation to confirm uniformity and stability
of the selection. Selection criteria: attractive flower
characteristics. Propagation: vegetative through many
generations. Breeder: Mrs H M Barclay, Findon, SA.
Choice of Comparators ‘Queen Elizabeth’ and ‘Sonia’
were chosen as comparators as these are the most similar
varieties of common knowledge on the basis of flower
colour. ‘First Love’ and ‘Roundelay’ were not considered
for reasons stated above.
