Applicant: Frank Bart Schuurman, Whenuapai, New Zealand. Agent: Grandiflora Nurseries Pty Ltd, Cranbourne, VIC. Characteristics (Table 46, Figure 16) Plant: habit narrow bushy, medium width. Young vegetative shoot: anthocyanin colouration medium, bronze to reddish brown. Stem thorns: present, lower surface concave. Leaves: size medium, light green, glossiness of upper side weak or absent. Terminal leaflet: size medium, cross section flat, margin undulation absent or very weak, leaf base obtuse. Flower bud: profile ovate. Flower pedicel: few prickles. Flower: size medium, double, rounded upper, lower profile flattened convex, sepal extensions weak, fragrance absent or very weak. Petals: size medium, colour middle zone inner side yellow-orange (RHS 15B), margin inner side yellow-orange (RHS 15C), middle zone outer side yellow-orange (RHS 16B), margin outer side yellow-orange (RHS 16B), basal spot absent on both sides, margin reflexing strong, undulation weak. Stamen: filament yellow. Seed vessel: small, pitcher shaped. Flowering: remontant cut flower rose. (Note: all RHS colour chart numbers refer to 1986 edition.) Origin and Breeding Controlled pollination : seed parent ‘Kordaba’ A syn Lambada A x pollen parent ‘Korbacol’ A syn Texas A in a planned breeding program in New Zealand in 1994. The seed parent is characterised by orange-pink flower colour (RHS 33C-35B) and the pollen parent was characterised by yellow (RHS 12 B-C) flower colour but with fewer thorns. Selection criteria: selected on the basis of vigorous growth, high production, non fading golden yellow colour. Propagation: vegetative methods through many generations. Breeder: F B Schuurman, Franko Roses New Zealand Ltd, Whenuapai, New Zealand. Choice of Comparator ‘Cocktail’ was chosen as the sole comparator as it is in the opinion of the qualified person the most similar cut flower variety of common knowledge on the basis of flower colour. ‘Cocktail’ could be traced back in the pedigree of the candidate through the pollen parent ‘Korbacol’ A (‘Berolina’ x ‘Cocktail’). The parents were not considered for reasons stated above. 66

Young shoot: green, prickles present. Thorns: very few long, short prickles. Leaf: size large, colour dark green, semi-glossy. Terminal leaflet: cross section slight concave, margin undulation weak, leaf base rounded. Flower pedicel: few prickles. Flower bud: profile broad ovate. Flower: double, size large, irregularly round above, flat upper, flattened convex lower profile. Sepal extensions: medium. Fragrance: medium to strong. Petals: size large, colour of middle zone inner side RHS 15A, marginal zone inner side RHS 38A, middle zone outer side RHS 16A, marginal zone outer side RHS 48A, basal spot absent, very weak margin reflexing, absent or very weak undulation, stamen filament yellow. Flowering habit: remontant. (Note: all RHS chart numbers refer to 1995 edition.) Origin and Breeding Controlled pollination: seed parent ‘Burway’ (US Plant Patent 5,827) x pollen parent ‘Aroyqueli’ syn Gold Medal (US Plant Patent 5,177) in a planned breeding program. The seed parent is a hybrid tea rose and has a significantly shorter plant habit. The pollen parent bears only slightly fragrant flowers of a deep yellow colouration (RHS 14B-C). Selection criteria: seedlings from the cross were grown and selection was made on the basis of the following selection criteria: unusual fresh flower colouration, long stems and fruity fragrance. Propagation: vegetatively through many generations. Breeder: A. Michael Dykstra, Canton, Missouri, USA. 67
