PLANT VARIETIES JOURNAL 1999 VOL 12 NO. 4 weak, core diameter medium-large (mean 13.7 mm), core shape elliptical, core woody spike sometimes present, outer pericarp colour at maturity (fruit soft) light green (RHS 138B-138D), inner pericarp colour at maturity (fruit soft) green (RHS 138B-138D), fruit core colour at maturity (fruit soft) greenish white (RHS 155A-155B), fruit seed colour at harvest, while still in flesh, black (RHS 200A), seed colour when dry, brown (RHS 165A-165B), brix level at maturity for consumption medium (mean 14.3%), titratable acidity at maturity high, vitamin C content medium. Plant: time of vegetative budbreak early (mid Sep), time of beginning of flowering medium (early Nov), time of maturity for harvest medium (early Apr). (Note: all RHS colour chart numbers refer to 1986 edition.) Origin and Breeding Controlled Pollination: seed parent ‘Hayward’ x pollen parent DA02_03. The seed parent was characterised by green flesh, medium core, fruit size 100g, tangy flavour, slightly flattened ovoid shape. The pollen parent was chosen because it was one of the earliest flowering males in DA02. Crossing took place in Nov 1983 in New Zealand. From this cross seedling number 47-5-5d, code ‘Hort DA1’, later named ‘Tomua’ was selected in 1990. Selection criteria: very early maturing (4-5 weeks ahead of ‘Hayward’), medium fruit size, sweet tasting, green coloured flesh, hair easily brushed off. ‘Tomua’ can be distinguished from the seed parent, ‘Hayward’ by the shape of the stylar end of the fruit being more pointed, the hairs of the fruit being more bristly and easily removed by light brushing, the skin of the fruit being more reddishbrown, earlier budbreak and flowering date and a harvest date 4 weeks ahead of ‘Hayward’. The petals on flowers of ‘Tomua’ remain cupped around the ovary after pollination whereas those of ‘Hayward’ rise or fold back to expose the ovary. Propagation: ‘Tomua’ will be propagated by vegetative cuttings or by grafting on to seedling or clonal A. deliciosa rootstocks. Breeders: Russell Lowe, Hinga Marsh, The Horticulture and Food Research Institute of New Zealand Ltd. Choice of Comparator ‘Hayward’ is the most common kiwifruit grown world-wide and is the closest similar variety of common knowledge. ‘Hayward’ is also the seed parent of the candidate variety. The pollen parent was not considered for the trial as kiwifruit plants are dioecious and thus male plants produce no fruit. Comparative Trial Comparator: ‘Hayward’. Location: Te Puke Research Centre, Te Puke, New Zealand (Latitude 37º 49´ South) 1993/97. Conditions: a fully replicated trial was planted in 1990. Rootstocks used were clonal ‘Hayward’ cuttings. 10 replicates of each selection were planted. Vine spacing was 5m between rows and 6m between plants in the row. Measurements: taken from each plant at random, one sample per plant.

Applicant: Kristine and Geofrey Napier, Martin, WA. Agent: Wyve Horticultural Services, Lilydale, VIC. Characteristics (Table 28, Figure 23) Plant: semi upright aromatic shrub, size medium to tall. Stem: upright, weakly pubescent. Leaf: opposite, decussate, length mean 36.80mm, width narrow mean 5.3mm, shape linear, mostly straight, margin entire, recurved, acute apex, base sessile, leaf colour green RHS 137A, pubescence weak, aromatic. Inflorescence: spike, peduncle absent. Spike: length mean 21.40mm, mean width 12.5mm. Flower: petal colour purple RHS 79A. Terminal bract: length long mean 19.70mm, width narrow mean 9.20mm, shape linear, margin undulating, colour purple RHS 77B. (Note: all RHS colour chart numbers refer to 1995 edition.) Origin and Breeding Open pollination followed by seedling selection: ‘Darling Crown’ arose as the result of a single cycle of seedling selection from open pollinated of Lavandula stoechas (common form) at applicant’s property at Roleystone, WA. The parental plants were characterised by one single upright flower head where as the selected seedling was characterised by twelve smaller flower heads and bracts radiating outwards from the base of the central upright flower structure. ‘Darling Crown’ has been propagated for at least 5 generations to ensure uniformity and stability. Selection criteria: basal radiating flower spikes, flower and bract colours. Breeder: K Napier, Roleystone, WA. Propagation: vegetative. Choice of Comparators Lavandula stoechas ‘Winter Purple’ was chosen because it is the closest variety of common knowledge. Lavandula stoechas (common form) was not considered because it is clearly distinguishable from the candidate by the characteristic stated above. Comparative Trial Comparator: ‘Winter Purple’. Location: Lilydale, VIC, winter-spring 1999. Conditions: trial conducted in polyhouse, plants propagated from cutting, rooted cuttings planted into 140mm pots filed with soilless potting mix (pine bark base), nutrition maintained with slow release fertilisers, pest and disease treatments applied as required. Trial design: ten pots of each variety arranged in a completely randomised design. Measurements: from all trial plants, one sample per plant. Prior Applications and Sales Nil.
