‘Interlene’<br />
Application No: 1998/263 Accepted: 29 Jan 1999.<br />
Applicant: Interplant B.V., Ne Leersum, The Netherlands.<br />
Agent: Grandiflora Nurseries Pty Ltd, Cranbourne, VIC.<br />
Characteristics (Table 37, Figure 12) Plant: habit narrow<br />
bushy, width medium. Young vegetative shoot: anthocyanin<br />
colouration very strong, purple. Stem thorns: present, lower<br />
surface concave. Leaves: size small, medium green,<br />
glossiness of upper side medium. Terminal leaflet: size<br />
medium, cross section slight concave, margin undulation<br />
absent, leaf base rounded. Flower pedicel: medium prickles.<br />
Flower bud: profile ovate. Flower: size small, double, flat<br />
upper and lower profile, sepal extensions medium,<br />
fragrance weak. Petals: size small, colour inner and outer<br />
side white (RHS 155D), basal spot absent on both sides,<br />
margin reflexing strong, undulation weak, stamen filament<br />
white. Seed vessel: small, pitcher shaped. Flowering:<br />
remontant cut flower rose. (Note: all RHS colour chart<br />
numbers refer to 1986 edition.)<br />
Origin and Breeding Controlled pollination: seed parent<br />
‘unnamed seedling’ x pollen parent ‘unnamed seedling’ in a<br />
planned breeding program at the applicant’s nursery in<br />
Leersum, The Netherlands, in 1992. Both parents are<br />
proprietary breeding stock plants within breeder’s private<br />
collection. Selection criteria: selected on the basis of<br />
vigorous growth, high production, pure white colour.<br />
Propagation: by vegetative methods through many<br />
generations. Breeder: Mr. G. P Ilsink, Interplant B.V.,<br />
Leersum, The Netherlands.<br />
Choice of Comparator ‘Tineke’ was initially considered as<br />
a comparator, however it was not finally included in the trial<br />
as it significantly differs from the candidate in stamen<br />
filament colour, which is yellow-green in ‘Tineke’ but white<br />
in ‘Interlene’. ‘Prebian’ A syn Bianca A was finally chosen<br />
as the sole comparator as it is in the opinion of the qualified<br />
person the most similar cut flower variety of common<br />
knowledge on the basis of flower colour.<br />
Comparative Trial Comparator: ‘Prebian’ A syn Bianca A .<br />
Location: Cranbourne, VIC, Jul – Dec 1999. Conditions:<br />
plants grown in the soil within environmentally controlled<br />
glasshouse. Measurements: 20 random samples of each<br />
variety collected over a five month period.<br />
