Characteristics (Table 5, Figure 28) Plant: growth habit<br />
erect, height short (mean 24.3cm), density medium, stem<br />
hairiness weak, branching attitude erect. Leaf: length short<br />
22<br />
(mean 95.2mm), width medium (mean 16.7mm),<br />
length/width ratio medium (mean 5.7), position of broadest<br />
part middle third, shape of apex acute, main colour grey<br />
green, hairiness of upper side absent or very weak, hairiness<br />
of lower side weak, undulation of margin absent or very<br />
weak. Peduncle: length medium (mean 78.7mm), branching<br />
absent. Flower Bud: shape of apex pointed, colour of bud<br />
yellow (RHS 12A). Flower Head: predominant position<br />
above foliage, diameter medium (mean 53.4mm), lateral<br />
view of lower part concave, lateral view of upper part<br />
concave, number of bracts many, number of whorls of<br />
bracts many (mean 8). Involucre: number of colours one.<br />
Bract: length medium (mean 16.7mm), width narrow (mean<br />
4.7mm), length/width ratio 3.6, number of colours visible<br />
one, colour of bract yellow (RHS 9A). Disc: diameter<br />
relative to diameter of flower head less then one third.<br />
Pappus: colour yellow. Time of flowering: early. (Note: all<br />
RHS colour chart numbers refer to 1995 edition.)<br />
Origin and Breeding Open pollination: Bracteantha<br />
varieties ‘Sunraysia Splendour’ A , ‘Argyle Star’ A ,<br />
‘Menindee Magic’ A and unnamed selections breeders code:<br />
59, 66 and 67. Hybridisation took place at Redlands<br />
Nursery Pty Ltd, <strong>Australia</strong> in 1995. The most likely seed<br />
parent ‘Sunraysia Splendour’ A was characterised by<br />
yellow/orange cupped inflorescences. The possible pollen<br />
parents were characterised by white, pale lemon, orange,<br />
pale orange and pink blooms respectively. Plants were<br />
grown in close proximity and flower heads were rubbed<br />
together manually, seed heads matured and seeds<br />
germinated as they fell in the propagation trays. One<br />
thousand seedlings were potted in 1996 and Golden<br />
Nuggets was selected. Selection criteria: compact, bushy<br />
and erect growth habit and flower colour. Propagation:<br />
stock plants were generated vegetatively and found to be<br />
uniform and stable. Propagation: by vegetative cuttings.<br />

Choice of Comparators Grouping characteristics used in<br />
identifying the comparators were- Plant growth habit erect.<br />
Involucre: number of colours one. Bract: main colour of<br />
bracts yellow. On this basis, the most similar variety of<br />
common knowledge was found to be ‘Hastings Gold’ as the<br />
comparator because of its similar plant growth habit,<br />
predominant yellow flower bract and small, concave flower<br />
head. Initially, on grouping characteristics, varieties with<br />
predominant yellow bracts (‘Sunraysia Splendour’ A ,<br />
‘Coolgardie Gold’ A , ‘Colourburst Gold’ A , ‘Dargan Hill<br />
Monarch’ Yellow, ‘Diamond Head’, ‘Golden Beauty’ TM )<br />
were chosen. ‘Sunraysia Splendour’ A and ‘Coolgardie<br />
Gold’ A are similar in plant growth habit, but produce<br />
convex flower heads compared to concave flower heads of<br />
‘Golden Nuggets’ A . ‘Colourburst Gold’ A and ‘Dargan Hill<br />
Monarch’ Yellow have tall plant growth habit with very<br />
large flower heads held on long peduncles unlike ‘Golden<br />
Nuggets’ which is a low-compact plant growth habit with<br />
medium size flower heads produced on shorter peduncles.<br />
‘Diamond Head’ and ‘Golden Beauty’ TM have short and<br />
narrow leaves with small flower heads unlike ‘Golden<br />
Nuggets’ which has larger leaves and flowers.<br />
Comparative Trial Location: Redlands Nursery Pty Ltd,<br />
Redland Bay, QLD, autumn to spring 2001. Conditions:<br />
plant propagated by cuttings and rooted cuttings potted to
