PLANT VARIETIES JOURNAL 1999 VOL 12 NO. 4 short. Flower: colour white and purple pink, size large, tepal spread medium, outer tepal shape broad obovate, depth of emargination shallow, stripes very few (absent), colour white RHS 155C at margins and base red pink RHS 68A-B at the apex and red RHS 58A-B at the centre; inner lateral tepals shape elliptic, colour yellow RHS 4C-D at centre and base, red purple RHS 68A-B at the apex, stripes medium thickness small to medium; inner median tepal yellow colour absent, stripes present. Stamens: filament purple pink, spots present, anther colour greenish. Ovary: anthocyanin weak (medium), style purple pink, stigma purple pink, spots absent. (Note: data in parenthesis denotes Dutch observations, all RHS numbers referred to in local observation were based on the 1986 edition). Origin and Breeding Spontaneous mutation: Alstroemeria ‘Stamond’ A at the applicant’s nursery at Aalsmeer, The Netherlands. The parent ‘Stamond’ A is a propriety variety developed by the applicant. Selection criteria: ‘Testapink’ was chosen on the basis of flower characteristics and growth habit. Propagation: a number of mature stock plants were generated from the original sport by tissue culture through 10 generations to confirm uniformity and stability. ‘Testapink’ will be commercially propagated by tissue culture. Breeder: Van Staaveren BV, Aalsmeer, The Netherlands. Choice of Comparators ‘Vienna’ A , ‘Stamond’ A , ‘Stalbel’ A , ‘Cavalier’, and ‘Alaska’ A were initially considered as the similar varieties of common knowledge based on previous published descriptions in Plant Varieties Journal. ‘Vienna’ A (PVJ Vol. 9 No. 3) was chosen because of similarities in flower colour and ‘Stamond’ A was included (PVJ Vol. 9 No. 3) because it is the parental variety. ‘Stalbel’ A (PVJ Vol. 3 No. 4) and ‘Cavalier’ PVJ Vol. 7 No. 2) were rejected because of dark yellow colour in the inner lateral tepals and ‘Alaska’ A described in (PVJ Vol.7 No. 4) because of paucity of red purple tints. Comparative Trial Comparators: ‘Vienna’ A and ‘Stamond’ A . Comparisons of most of the characteristics are based on Dutch trials, which were assessed under conditions of controlled environment in glasshouses. Detailed flower descriptions of the candidate variety are based on plants growing in soil in a multispan polyhouse in Bunyip, VIC. Flowers from these plants were cut in bud in Oct 1999 and transported to Rye VIC, and placed in a solution of 5% sugar and 1 ml/l chlorine bleach. The flowers were assessed three to four days later.

DESCRIPTIONS PLANT VARIETIES JOURNAL 1999 VOL 12 NO. 4 ASTER Aster hybrid ‘Dark Milka’ Application No: 98/260 Accepted: 18 Jan 1999. Applicant: Nachtvlinder B.V., Ter Aar, The Netherlands. Agent: Yates Botanicals Pty Ltd, Somersby, NSW. Characteristics (Table 4, Figure 11) Plant: habit upright, height medium. Stem: internodes medium, pubescence absent-very weak, anthocyanin at internode and leaf axil present. Leaf: long (average length 139mm), shape elliptic, dentations at distal part of margin, apex acute, anthocyanin absent, sessile, pubescence absent. Inflorescence: capitulum, distributed along the axis, more than two whorls of ray florets. Ray florets: very many, attitude horizontal, length medium, shape narrow elliptic, cross sectional shape concave, curvature of longitudinal axis and tip straight, apex acute, dentation of apex absent, colour of upper side violet (RHS 87A-B, 1995), colour less intense towards base. Involucre: many bracts, length medium, shape funnelform, bract position free, bract overlapping medium. Origin and Breeding Spontaneous mutation: ‘Milka’. The parent is characterised by having a violet flower corresponding to RHS 85A (1995). Following mutation, an additional cycle of selection took place in Ter Aar, The Netherlands in 1994. Selection criteria: flower colour. Propagation: stock plants were created from cuttings and micropropagation and were found to be uniform and stable through many generations. ‘Dark Milka’ will be commercially propagated by vegetative cuttings from micropropagated motherstock created from the stock plants. Breeder: P.J.F. Akerboom, Nachtvlinder B.V, Holland. Choice of Comparators ‘Milka’ and ‘Karmijn Milka’ were used for the comparative trial as these varieties have similar flower forms and colours and arise from the same breeding program. ‘Milka’ is also the parental variety. No other similar varieties were identified. Comparative Trial Comparators: ‘Milka’, ‘Karmijn Milka’. Location: Somersby, NSW, autumn-spring 1999. Conditions: trial initially grown under glass with long days provided by incandescent lights until flower initiation in Aug 1999, then finished in open beds in full sun, plants propagated from cutting and micropropagation, rooted cuttings planted into 150mm pots filled with soilless potting mix (pine bark & copra peat base), nutrition maintained with slow release fertilisers, pest and disease treatments applied as required. Trial design: 40 pots of each variety arranged in a completely randomised design. Measurements: from ten plants at random. One sample per plant.
