Applicant: Kim Hawks, North Carolina, USA. Agent: Plants Growers Australia, Wonga Park, VIC. Characteristics (Table 18, Figure 32) Plant: growth habit erect, density dense, height mean 64cm. Stem: diameter at base mean 5mm, number of branches zero to two, colour light yellow-green (RHS 145 A-B), hairiness present. Leaf: arrangement alternate, shape of apex acute to acuminate, shape of base attenuate, presence of hair on upper surface present, presence of hair on lower surface present. Basal leaf: length (mean) 142mm, width (mean) 37.5mm, shape ovate to lanceolate, margin serrate. Cauline Leaf: shape lanceolate, margin serrate to entire. Inflorescence: scape arrangement solitary. Flowers: ray florets number per inflorescence mean 22, colour red-purple RHS 63 A-D, disk florets colour before dehiscence green RHS 143B-C, colour after dehiscence bronze ca. RHS 177A-B. Flowering: duration long. (Note: all RHS numbers refer to 1995 edition). Origin and Breeding Seedling selection: seed parent Echinacea purpurea is characterised by large leaf size, tall scapes and low inflorescence number. After an initial chance seedling (Atlanta, Georgia, USA 1990) crossing and evaluation was undertaken for a further three generations and one seedling was selected. Selection criteria: short scape length and high inflorescence number. Propagation: originally asexually by root cuttings and were found to be uniform and stable. The variety ‘Kim’s Knee High’ will be commercially propagated in tissue culture. Breeder: Kim Hawks, North Carolina, USA. Choice of Comparators Grouping characteristic used to identify the most similar varieties of common knowledge were – Ray Floret: colour red-purple. On the basis of this grouping characteristic the parental variety Echinacea purpurea was included in the trial. All other varieties differed either in plant height and/or ray floret colour. Comparative Trial Location: Park Orchards, VIC, Autumn-Summer 2001-2002. Conditions: trial conducted in the open, plants propagated from divisions, established in 140mm pots, transferred to 200mm pots (15/5/01). Pots filled with soilless, pine bark based mix and maintained with controlled release fertilizers. Appropriate pest and disease treatments were applied as required. Trial design: ten pots of each variety arranged in a completely randomised design. Measurements: from ten plants one sample per plant.

Applicant: New Farm Crops Ltd, Lincolnshire, UK. Agent: Heritage Seeds Pty Ltd, Mulgrave, VIC. Characteristics (Table 19, Figure 53) Plant: growth habit erect, height short to medium (mean 84.23cm), frequency of plants with recurved flag leaves absent or very low. Lowest leaves: hairiness of leaf sheaths absent. Flag leaf: anthocyanin colouration of auricles present, intensity of anthocyanin colouration of auricles medium. Flag leaf: glaucosity of sheath medium to strong. Time of ear emergence: medium. Awns: anthocyanin colouration of tips present, intensity of anthocyanin colouration of tips medium, length short (mean 100.69mm). Ear: glaucosity absent or very weak, attitude semi-erect, number of rows two, shape parallel, density medium, length long (99.5mm). Rachis: length of first segment short, curvature of first segment weak. Sterile spikelet: attitude parallel to weakly divergent. Median spikelet: length of glume and its awn relative to grain equal. Grain: rachilla hair type long, husk present, anthocyanin colouration of nerves of lemma medium, spiculation of inner lateral nerves of dorsal side of lemma absent, hairiness of ventral furrow absent, disposition of lodicules clasping. Seasonal type: spring. Origin and Breeding Controlled pollination: seed parent ‘Chalice’ x pollen parent NFC breeding line. Initial cross was made in January 1994 in the UK. F 1 plants were grown in the field between Mar and Aug 1994. 2000 F 2 plants from this population were sown in New Zealand in Oct 1995 and harvested in February 1996. 300 single ears were selected from the population in NZ and returned to the UK. 300 F 3 progenies were sown in rows in the field in the UK and grown from March 1996 to August 1996. 35 F 3 lines were selected and single F 4 plants harvested from the selected rows. Selections from this population were based on early maturity, disease resistance and large grain size. 35 F 4 lines (6921-01 to 6921-35) were shipped to NZ and grown in 2 metre long rows from October 1996 to February Table 19 Hordeum varieties 1997. Disease resistance was used to select two lines that were sent to Australia for evaluation. The two lines were planted during 1998 as single plots. During this period the lines were assessed for general agronomic performance including type, maturity, height and straw strength. The plots were harvested for yield and grain recovery. Samples were submitted for malting quality evaluation. 6921-23 was selected as the most promising line on the basis of good agronomic performance and malting quality. 6921-23 was selected for inclusion in replicated trials during 1999. During 2000 the line was included in a number of replicated trials across the barley growing regions of southern NSW and Victoria. Pure seed was introduced from the breeder during 2000 and harvested as the beginning of the seed production process. A greater number of wider ranging replicated trials were conducted during 2001 to continue to assess the agronomic performance and malting quality. The line was submitted for PBR and the field DUS trial was conducted. Pure seed multiplication continued during the same season. Selection criteria: high yield, disease resistance, high malting quality. Propagation: seed. Breeder: New Farm Crops Ltd, Lincolnshire, UK. Choice of Comparators Grouping characteristics used in identifying the most similar varieties of common knowledge were – Plant: growth habit erect, height short, maturity medium; Ear: attitude semi erect. On the basis of these grouping characteristics following comparator varieties were included in the trial: ‘Gairdner’ A , ‘Osprey’ A syn Galaxy A , ‘CK85’, ‘Sloop’ A , and ‘Schooner’. The seed parent ‘Chalice’ was not included as it has a different growth habit (intermediate), leaf type (long and recurved), awn length (long) and ear length (long). The pollen parent was not included as it is of later maturity than the candidate variety. Comparative Trial Location: sown on “Shrublands”, Heritage Seeds’ Research facility, Riverina Highway, Howlong, NSW, (Latitude 35º60′ South, elevation 150m), autumn-summer 2001. Conditions: trial sown into a redbrown soil with good moisture levels at 55 kg/ha sowing rate with 100 kg/ha of DAP. Trial design: randomised plots 1.2m x 5m in 3 replicates. Measurements: five plants randomly selected per replicate from a total of approximately 1,100 plants. Prior Applications and Sales Nil.
