PLANT VARIETIES JOURNAL 1999 VOL 12 NO. 4 AVOCADO Persea americana ‘Llanos Hass’ Application No: 97/159 Accepted: 6 August 1997. Applicant: Anthony Philip Llanos and Cassandra Ann Llanos, Hope Valley, WA. Characteristics (Table 5, Figure 28) Plant: habit vigorous, upright, height medium to large. Stem: anthocyanin not present in young shoots. Leaf: attitude horizontal, blade folding concave, length long, width narrow, size large (183mm x 71mm), shape lanceolate (length:width ratio 2.6), tip acute, anthocyanin present in newly emerged leaves, anise aroma not present when crushed. Inflorescence: size axis length medium, Type ‘B’. Flower: habit late, pubescence on sepals medium. Mature fruit: early maturing, size small (97mm x 64mm), shape base rounded stylar region slightly depressed, length:diameter ratio medium (1.5:1), stalk cavity present, relief of surface rough. Pedicel: length medium, shape cylindrical, nailhead shape present, pedicel/peduncle combined length medium (81mm). Ripe fruit: colour of skin purple black, thickness of skin thick (1.75mm), texture of skin leathery, adherence of skin to flesh medium, main flesh colour yellow, wide green layer of flesh next to skin, fibres in flesh inconspicuous, flesh texture smooth, seed set into cavity tight. Seed: size compared to fruit large (flesh weight:seed weight ratio 3.7:1), shape in longitudinal section base flattened, apex conical. Origin and Breeding Open pollination followed by seedling selection: an open pollinated seedling was selected at applicant’s property in Hope Valley, WA, which displayed precocious and consistent fruit set that was similar to ‘Hass’ but consistently matured approximately 4-6 weeks earlier than ‘Hass’. DNA profiling has shown that ‘Hass’ is likely to be one of the parents. Selection criteria: fruit quality and maturity. Propagation: by vegetative grafting onto seedling rootstocks. Breeders: Anthony and Cassandra Llanos, Hope Valley, WA, Australia. Choice of Comparators ‘Hass’ was chosen as the sole comparator because it is the most similar variety of common knowledge. DNA profiling indicated that ‘Llanos Hass’ is genetically very similar to ‘Hass’. Comparative Trial Comparator: ‘Hass’. Location: Hope Valley, WA (Zone 50) approximately 30Km south of Perth. Conditions: scion wood from the original ‘Llanos Hass’ seedling tree was grafted onto Guatemalan seedling rootstocks, trees were planted in 1996 at spacings of 5.0m x 2.5m to a total of 100 trees. ‘Hass’ trees grafted onto Guatemalan seedling rootstocks were planted randomly within the ‘Llanos Hass’ block in 1997 to a total of 10 trees. The plants were grown in the field, soil being deep sands; all trees were managed in the same manner with regard to irrigation and nutrition. Irrigation using mini sprinklers aimed to wet 100% of soil in the drip zone. Nutrition requirements were based on annual leaf analysis and applied by fertigation. Trial design: the trial set up was of a completely randomised design. Measurements: samples were randomly collected from trees selected at random for analysis. Prior Applications and Sales First Australian sale in 1998. Description: Alec McCarthy, Agriculture Western Australia, Bunbury, WA.

DESCRIPTIONS PLANT VARIETIES JOURNAL 1999 VOL 12 NO. 4 BOX HONEYSUCKLE Lonicera nitida ‘Paradise Royal Flush’ Application No: 98/219 Accepted: 30 Oct 1998. Applicant: R. J. Cherry, Kulnura, NSW. Characteristics (Table 6, Figure 18) Plant: vigorous, dense, upright, branching, evergreen shrub. Stem: round in cross section, new stem growth purple (ca. RHS 187A) fading with age. Leaf: opposite, length 17mm (average), width 11mm (average), shape ovate-cordate, deeply concave in cross section, margin entire with medium undulation, apex blunt acuminate, base slightly cordate-truncate, colour of upper surface dark green (RHS 147A), lower surface dull green (RHS 146B), new growth purple (RHS 187A). Flower: trumpet shaped, borne in pairs in the leaf axils of new season’s growth, size small (average diameter 10mm) with five fused petals, five free anthers becoming fused half way down the corolla tube, colour creamy-lime (RHS 154D). (Note: all RHS colour chart number refers to 1995 edition) Origin and Breeding Controlled Pollination: Lonicera nitida ‘Aurea’ (seed parent) x Lonicera nitida Common form (pollen parent) in a planned breeding program in 1993. Several seeds were developed as a result of this cross. Seedlings were produced and raised to maturity in 1994. Selection criteria: from the batch of these seedlings, ‘Paradise Royal Flush’ was selected for its vigour, dense growth habit and deeply coloured new growth. Propagation: asexually by cuttings through three generations to ensure uniformity and stability. Breeder: R. J. Cherry, Paradise Plants, Kulnura, NSW, Australia. Choice of Comparator The comparator used in this trial is the Common form of Lonicera nitida. This variety has been chosen as it is the most similar variety of common knowledge and is also the pollen parent. The seed parent Lonicera nitida ‘Aurea’ was not used as it is clearly different from the candidate variety in leaf colour (yellowgreen ca. RHS 144C) which is the primary distinguishing characteristic. Comparative Trial Comparator: Common form of Lonicera nitida. Location: trial conducted at Paradise Plants, Kulnura, between 1997-1999. Conditions: plants raised on their own roots from cuttings. Grown in 200mm pots in commercial potting mix and potted up into 250mm pots after 1 year, grown under full sun with overhead watering. All plants were subjected to the same chemical treatments for crop protection and nutrition as required. Trial design: 12 plants of each variety arranged in a complete block design. Measurements: taken from 10 plants of each variety. All leaf measurements are taken from mature leaves. Prior Applications and Sales No prior application. First sold in Australia in Oct 1997.
