Application No. 98/034 Accepted: 7 Jul 1998.
Applicant: Konst Alstroemeria BV, Nieuwveen, The
Netherlands.
Australian: Maxiflora Pty Ltd, Monbulk, VIC.
Characteristics (Table 4, Figure 25) Plant: stem length
medium, stem thickness medium, density of foliage
medium. Leaf: shape narrow elliptic, longitudinal axis of
blade recurved, length medium, width medium.
Inflorescence: umbel branch number medium, length
medium, pedicel length long. Flower: colour red purple,
size large, tepal spread medium to broad; outer tepal shape
broad obovate, depth of emargination deep, stripes very
few, colour red purple RHS 61D at margins, RHS 61B at
apex and cream with pink tinge at base; inner lateral tepals
shape elliptic, colour yellow RHS 5A (RHS 14A) at centre
and margins, red purple RHS 61C at apex, stripes medium
to many; inner median tepal yellow colour present, stripes
present. Stamens: filament red, spots absent; anther colour
brownish. Ovary: anthocyanin weak (medium to strong);
style pink, stigma colour pink, spots absent. (Characteristics
given in parenthesis are from Dutch observations).
Origin and Breeding Controlled pollination: seed parent
85-34 x pollen parent 91-0-1 in a planned breeding program
at the applicant’s nursery at Nieuwveen, The Netherlands.
The female parent is dark pink/yellow flowered orchid type
Alstroemeria with stem length approx. 150cm. The male
parent is a pink butterfly type Alstroemeria with stem length
approx. 60cm. Both parents are proprietary breeding lines
developed by the applicant. Selection criteria: from this
cross, ‘Roma’ was chosen on the basis of flower
characteristics and growth habit. Propagation: a number of
mature stock plants were generated from the original
seedling by tissue culture through 10 generations to confirm
uniformity and stability. ‘Roma’ will be commercially
propagated by tissue culture. Breeder: Konst Alstroemeria
BV, Nieuwveen, The Netherlands.
Choice of comparator On the basis of flower colour
‘Cobra’ A was chosen as the most similar variety of common
knowledge. ‘Cobra’ A is a variety also developed from the
same breeding programme. No other similar varieties have
been identified.
Comparative Trial Comparator: ‘Cobra’ A . Comparisons
of most of the characteristics are based on Dutch trials,
which were assessed under conditions of controlled
environment in glasshouses. Characteristics of the
comparator are derived from a previous description in the
Plant Varieties Journal (PVJ 8.1 pp7). Detailed flower
descriptions of the candidate variety are based on plants
growing in red kraznozem soil in a multispan polyhouse in
Monbulk, Victoria. Flowers from these plants were cut in
bud in Jan 1999 and transported to Rye, Victoria, and placed
in a solution of 5% sugar and 1 ml/litre chlorine bleach. The
flowers were assessed four to five days later.
