done for two more years to confirm the uniformity and
stability of the selection. Selection criteria: seed yield,
larger leaf size and early maturity. Propagation: by seed.
Breeder: Stewart Sutherland, Tooma, NSW.
Choice of Comparators ‘Tattoo’, ‘New Tetilla’ and ‘USA
Tetilla’ were chosen as the most similar tetraploid varieties
of common knowledge on the basis of similar heading
dates. ‘USA Tetilla’ is one of the original source materials
from which ‘Robust was developed. ‘New Tetilla’ is a
further selection from ‘USA Tetilla’.
Comparative Trial Comparators: ‘Tattoo’, ‘New Tetilla’
and ‘USA Tetilla’. Location: Whittlesea, VIC, springsummer,
1999. Conditions: planted as spaced plants in open
beds, managed for even and uniform growth. Trial design:
60 plants of each variety arranged in randomised complete
blocks with 6 replicates. Measurement: from all trial plants.
Prior Applications and Sales
No prior applications. First Australian sales in May 1997.

Lonicera nitida

‘Little Nikki’
Application No: 1999/159: Accepted: 21 Jun 1999.
Applicant: David George Kent, Morayfield, QLD.
Characteristics (Table 30, Figure 26) Plant: vigour
medium, habit erect, compact, height medium, width
medium, size small to medium. Stem: slender straight many
branched red brown anthocyanin present weakly and
proximally. Leaf: opposite, simple, entire, shortly petioled,
length long, width narrow, size small, shape elliptical, apex
obtuse/mucronulate, base cuneate, incisions of margin
absent, undulations of margin weak to medium, variegation
present, primary colour green and yellow-green (137A,
141A and 144A), variegation colour white and yellowwhite
and yellow (155A and 158B and 11B, 12C, 2D)
variegation occurrence/expression marginal irregular
narrow to broad band, variegation intensity strong, variable,
blistering of blade weak. (Note: all RHS colour chart
numbers refer to 1995 edition)
Origin and Breeding Spontaneous mutation: from
common form of Lonicera nitida. The source material is an
old variety, cultivated since the turn of the century, with mid
to dark green non-variegated leaves. A variegated mutant
was first observed in 1995 on the applicant’s property,
which was characterised by green and white-yellow
variegated foliage. Selection criteria: selected for variegated
leaves repeatedly for 5 selection cycles. Propagation: by
cuttings through about 10 generations to confirm the
uniformity and stability of the selection. ‘Little Nikki’ will
be commercially propagated vegetatively, as cuttings, from
stock plants. Breeder: David Kent, Morayfield, QLD.
Choice of Comparators ‘Silver Beauty’ with similar leaf
shape and variegation and the common form of Lonicera
nitida (the parent of the candidate variety) were chosen as
the similar varieties of common knowledge. ‘Paradise
Royal Flush’ and ‘Aurea’ initially considered as widely
available varieties, however, were finally excluded as they
lacked leaf variegation.
Comparative Trial Comparators: ‘Silver Beauty’ and
Lonicera nitida common form. Location: trials conducted at
D&N Tubestock Nursery, Morayfield, QLD, Jul-Dec 1999.
Conditions: 3-5 cm cuttings struck on 10 Jul 1999 in cutting
media in cells in igloo, planted on 7 Aug 1999 on their own
roots into 140mm pots into commercial 80:20
pinebark/sand potting mix with normal osmocote: Plants
were subsequently grown in full sun and watered as
required. Trial design: forty pots of each variety were
initially arranged in rows in four replicates. Measurements:
twenty samples at random for each variety. One sample per
plant. Leaf samples on the most recently matured leaf.
Prior Applications and Sales
No prior applications. First Australian sales Nov 1999.
