Applicant: Minister for Primary Industries, Natural Resources and Regional Development, Adelaide, SA and Grains Research and Development Corporation, Barton, ACT. Characteristics (Table 23, Figure 46) Plant: quality blue field pea, height medium, time of flowering late, maturity late (semi-determinate), plant anthocyanin absent. Foliage: colour green (RHS 137C), Leaf: 3-5 sets of leaflets, large stipule, strong dentation along entire length, sparse flecking, stipule length and breadth 8 x 4cm. Flower: standard white (RHS 155D) and raised, peduncle length from stem to first flower 6-8cm. Pod: shape straight, no curvature, pod length and maximum width 7.38 x 1.25cm, pod colour at maturity greyed-orange (RHS 163B), number of ovules 7.8 (average). Seed: shape spherical, size large, shape of starch grain simple, cotyledon colour green (RHS 137A), testa colour green (RHS 138C). Disease resistance: moderately resistant to downy mildew and has shown less susceptibility to ascochyta blight over conventional dun pea varieties. (Note: all RHS colour chart number refer to 1995 edition). Origin and Breeding Controlled pollination: seed parent breeding line M150-1 x pollen parent S.A. 1406, with final cross made in 1989. Breeding line M150-1 developed from complex crossing of Early Dun/ SA966/SA916. ‘Soupa’ is a sister line of both ‘Mukta’ and ‘Santi’. The parent plants were distinguishable from ‘Soupa’ in terms of leaf type, stipule size and dentation, flower colour, seed type and size. A single-plant, single-row pedigree system was employed. Selection of single plants commenced with the F 2 generation. In the F 3 -F 5 generations, emphasis was toward selection among families. ‘Soupa’ entered into replicated yield trials as M257-7-2 in 1993. Selection criteria: increased grain yield, seedling vigour, reduced bleaching of blue cotyledon colour at maturity, non-shattering of pod at harvest and high grain quality. Propagation: by seed. Breeder: S. M. Ali, SARDI, Adelaide, SA. Choice of Comparators ‘Bluey’ and ‘Jupiter’ were included in the comparative trial as these are similar varieties of common knowledge. ‘Bluey’, ‘Jupiter’ and ‘Soupa’ are all blue pea varieties. The parental genotypes were not considered for the trial because ‘Soupa’ is clearly distinguishable from these lines in characteristics stated above. The sister lines ‘Mukta’ and ‘Santi’ were not considered because these are white pea varieties. Comparative Trial Comparators: ‘Bluey’ and ‘Jupiter’. Location: Charlick Field Experimental Station, University of Adelaide, located 70km south-east of Adelaide, SA. Conditions: plants were raised in fallowed open plots. Trial design: plots arranged in randomised complete blocks, each plot was sown as a paired row 3m in length. The rows were 1m apart. Sowing rate was 40 seeds per plot. Measurements: 10 specimens per replication selected randomly from each plot. Prior Applications and Sales No prior applications. First sold in Australia in Apr 1998 under the name M257-7-2.

Applicant: Royal Botanic Gardens, Sydney, NSW. Characteristics (Table 24, Figures 26a, 26b) Plant: erect bushy shrub, height at flowering medium (mean 60cm), width at flowering wide (mean 28cm) with heavy branching (mean 7 at first flowering). Leaves: medium density on stem, leaf length medium (mean 68mm), width narrow (mean 52mm), large number of tertiary lobes (mean 32), predominant colour RHS 191A, upper leaf strongly pubescent. Stem: white pubescence. Inflorescence: umbel, consisting of flowers subtended by two rows of bracts that reflex on maturity (mean 11), diameter including bracts small (mean 76mm), individual bract length short (mean 35mm) and bract width narrow (mean 8mm), predominant colour RHS 155C. Time of first flowering intermediate. (Note: all RHS chart numbers refer to 1986 edition). Origin and Breeding Recurrent Phenotypic Selection over nine years: phenotypes from a coastal population (Kurnell, NSW) were screened on the basis of plant habit, suitability for tissue culture and response to cultivated conditions. After 24 cycles of tissue culture and 7 cycles of vegetative propagation ‘Starbright’ proved to be different from the original population (Population 1) as well as a closely located populations (see Choice of Comparators). In addition, ‘Starbright’ has been shown to be different from more than 100 other populations collected throughout the natural area of occurrence of A. helianthi. Selection criteria: medium bushy habit, ability to be propagated by tissue culture, vigorous growth in cultivation, small-medium numerous flowers. Breeder: employees of the Mount Annan Botanic Garden, Mount Annan, NSW. Choices of Comparators There were no varieties of common knowledge at the time of this application. Through the wide screening of Flannel Flower selections conducted over nine years, no other varieties similar in their propagation ability, cultivation characteristics or morphological characteristics were observed in cultivation or in the wild. The comparators were therefore the most phenotypically similar plants selected from the source population (within 100 m of collection of source material) (‘Population 1’) and the next nearest population (300 m from source material) (‘Population 2’). Comparative Trial Comparators: Population 1 and Population 2. Location: Mount Annan Botanic Garden Nursery, Mount Annan NSW (Latitude 34º 05´ South, elevation 100m), autumn-spring 1999. Conditions: trial conducted in a polyhouse, plants propagated from cuttings, rooted cuttings potted into 175mm pots filled with soilless potting mix (coir, sand 1:4), nutrition maintained with slow release fertiliser, no pests or diseases recorded. Trial design: fifteen pots of each variety arranged in a completely random design. Measurements: from 13-15 plants of each variety. One sample per plant. Prior Applications and Sales No prior applications. First sold in Australia in Sep 1998. Description: Cathy Offord and Lotte von Richter, Mount Annan Botanic Garden, Mount Annan, NSW.
