Characteristics (Figure 7) Plant: narrow bushy, remontant
cut flower rose. Young vegetative shoot: anthocyanin
colouration weak to medium, bronze to reddish brown.
Stem thorns: present, lower surface concave. Leaves: size
medium, light to medium green, medium glossiness on
upper side. Terminal leaflet: cross section slightly concave,
margin undulation weak, leaf base rounded. Flower pedicel:
medium to many prickles. Flower bud: profile ovate.
Flower: size medium to large, double, flattened convex
upper profile, flat lower profile, fragrance weak, petals size
small to medium, red colour group (RHS 45A to 46A),
basal spot present both surfaces, medium margin reflexing,
medium undulation, stamen filament red Seed vessel:
Medium, funnel shaped.
Origin and Breeding Controlled pollination: seed parent
‘unnamed seedling’ x pollen parent ‘unnamed seedling’ in a
planned breeding program at applicant’s nursery in
Ventimiglia, Italy. Both seed and pollen parents are
breeding lines developed by the same breeder. Selection
criteria: seedlings from the cross were grown and the new
variety was selected for cut flower production in
glasshouses or under other transparent cover, with strong
stems, reasonable fragrance and good Winter budform &
production. Propagation: vegetative for many generations.
Breeder: Ghione Luciano, Ventimiglia, Italy
Choice of Comparator The qualified person considers
‘Kardinal’ to be the most similar variety of common
knowledge on the basis of flower colour within the
greenhouse cut flower range. No other similar varieties of
common knowledge have been identified.
Comparative Trial The description is based on the official
Community Plant Variety Office certificate. The testing was
conducted by the Dutch authorities in Wageningen, The
Netherlands. The data was further confirmed by the QP
under glasshouse conditions at Cranbourne, VIC. The
candidate variety ‘Nirpstrip’ has a significantly higher
flower production, significantly less blind shoots in winter
and significantly longer vase life compared to those of the
existing variety ‘Kardinal’.
