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 />

Breeder: Dr K V Bunker, Redlands Nursery Pty Ltd, QLD.<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 />
