PLANT VARIETIES JOURNAL 1999 VOL 12 NO. 4 ‘Milka’ Application No: 97/312 Accepted: 25 Nov 1997. Applicant: Nachtvlinder B.V., Ter Aar, The Netherlands. Agent: Yates Botanicals Pty Ltd, Somersby, NSW. Characteristics (Table 4, Figure 11) Plant: habit upright, height short-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 semi-upright, 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 83A, 1995), even distribution of intensity of colour. Involucre: many bracts, length medium, shape funnelform, bract position free, bract overlapping weak. Origin and Breeding Controlled pollination: seed parent Butterfly series (A. pringlei x A. novi-belgii) x pollen parent “P. series” in a planned breeding program. The parents are characterised by having single, blue flowers. Following the cross, a single cycle of selection took place in Ter Aar, The Netherlands in 1991. Selection criteria: many whorls of ray florets, flower colour. Propagation: stock plants were created from cuttings and micropropagation and were found to be uniform and stable through many generations. ‘Milka’ will be commercially propagated by vegetative cuttings from micropropagated motherstock created from the stock plants. Breeder: P.J.F. Akerboom, Nachtvlinder B.V, The Netherlands. Choice of Comparators ‘Karmijn’ 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. The parents were excluded on the basis of their single flower form. No other similar varieties were identified. Comparative Trial Comparators: ‘Karmijn’, ‘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.

Applicant: Nachtvlinder B.V., Ter Aar, The Netherlands. Agent: Yates Botanicals Pty Ltd, Somersby, NSW. Characteristics (Table 4, Figure 11) Plant: habit upright, height short-medium. Stem: internodes medium, pubescence absent-very weak, anthocyanin at internode and leaf axil present. Leaf: long (average length 121mm), 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 semi-upright to horizontal, length medium, shape narrow elliptic, cross sectional shape concave, curvature of longitudinal axis and tip straight, apex acute, dentation of apex present, colour of upper side white (RHS 155D, 1995), even distribution of intensity of colour. Involucre: many bracts, length medium, shape funnelform, bract position free, bract overlapping strong. Origin and Breeding Controlled pollination: seed parent Butterfly series (A. pringlei x A. novi-belgii) x pollen parent “P. series” in a planned breeding program. The parents are characterised by having single, white flowers. Following the cross, a single cycle of selection took place in Ter Aar, The Netherlands in 1994. Selection criteria: many whorls of ray florets, flower colour. Propagation: stock plants were created from cuttings and micropropagtion and were found to be uniform and stable through many generations. ‘Peter’s White’ 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’, ‘Dark Milka’, ‘Karmijn Milka’, ‘Karmijn’ and ‘Mauve Parade’ were used for the comparative trial as these varieties have similar flower forms and vegetative traits and arise from the same breeding programme. The parents were excluded on the basis of their single flower form. No other similar double varieties with white colour were identified. Comparative Trial Comparators: ‘Milka’, ‘Dark Milka’, ‘Karmijn Milka’, ‘Karmijn’ and ‘Mauve Parade’. 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.
