Applicant: Chief Executive Officer, Agriculture Western <strong>Australia</strong>, South Perth, WA. Characteristics (Table 12, Figure 37) Plant: tall, erect vigorous. Stem: thickness medium, branch angle medium. Leaf: length medium, thickness thick, angle medium, apex hooked. Flowering time: early. Flower: arrangement narrow distal, density medium to dense, diameter small. Bud: main colour with cap yellow-green to red (RHS 145D-41B), without cap purple violet (RHS 81D). Petal: colour first opened violet (RHS 84B), at mid-maturity purple (RHS 77C). Flower nectary: colour first opened yellow orange (RHS 22B), at mid-maturity greyed purple (RHS 184C). Staminodia: outline narrow triangular, collar colour red purple (RHS 65D). Style: colour red purple (RHS 65D). Calyx tube: longitudinal furrowing medium, outline flared. (Note: all RHS colour chart numbers refer to 1986 edition.) Origin and Breeding Single plant selection: from open pollination of Chamelaucium uncinatum at Jurien Bay, Western <strong>Australia</strong>. The selected plant was distinctly different from the rest of the population and all other population surveyed in the following combination of characteristics; earlier time of flowering, smaller terminal flowers and longer stem. Selected in Oct 1991 and following a series of trials was successfully propagated vegetatively in 1992. Subsequent cutting propagated generations produced in 1995, 1996 and 1997. All of these plants were found to be uniform and stable. Selection criteria: early flowering, small terminal flowers, vigour. Propagation: cutting. Breeder: University of Western <strong>Australia</strong>, Nedlands, WA. Choice of Comparators ‘Mullering Brook’ was considered as the sole comparator as the most similar variety of common knowledge. ‘Early Hard’ was not considered for trial because ‘Jurien Brook’ is clearly distinguishable by its small flowers, compact and erect growth habit, deepened petal colour at base with maturity and its purple style at maturity. The original population was not considered because it is distinctly different from ‘Jurien Brook’ in the characteristics stated above. Comparative Trial Comparator: ‘Mullering Brook’. Location: Agriculture Western <strong>Australia</strong> Research Station, Medina, WA. Conditions: plants propagated by cuttings and planted in open field of sandy soil with drip irrigation and fertigation. Trial design: 15 plants of each variety, replicated randomised block design. Measurements: made on 20 typical organs from all plants. Prior Applications and Sales Nil. Description: Philip Watkins, Sunglow Flowers Pty Ltd, Perth, WA.
