PLANT VARIETIES JOURNAL 2000 VOL 13 NO. 1 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. Description: Ian Aberdeen, Aberdeen Consulting Pty Ltd., Kilmore, VIC.

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. Description: Peter Beal, Cleveland, QLD. 48
