initial seedling was selected in 1997 and cuttings were
propagated and the initial trials were set up in 1998. Trials
were increased to 50 plants to test stability and for favorable
characteristics in 1999. Selection criteria: flower colour and
suitability as a cut flower. ‘Grandbeta’ will be commercially
propagated by vegetative cuttings or budded from the stock
plants. Breeder: Mr. H Schreuders, Cranbourne, VIC,
Australia.
Choice of Comparators ‘Sundel’ A syn Delilah A was
considered as a comparator because of its similar growth
characteristics, with the exception of flower colour and
shape. It is the seed parent of the candidate variety.
‘Selcarbonium’ syn Honesty was initially considered as the
pollen parent. However, it was discarded due to its
dissimilar flower colour.
Comparative Trial Location: Cranbourne, VIC, Mar 2000
– Apr 2001, Measurements and other data were collected in
Mar 2001. Conditions: trial conducted in a glasshouse,
plants propagated from cuttings, plants of both candidate
and comparator were grown in an adjoining glass house
with the same controlled environment conditions in the soil.
Nutrition maintained by complete nutrient supplied through
fertigation, pest and disease treatments applied as required.
Trial design: rows of 30 metre flower beds of each variety.
Measurements: from twenty plants at random. One sample
per plant.
Prior Applications and Sales
No prior applications. First sold in Australia in Mar 2000.

(Note: All RHS colour chart numbers refer to 1995 edition.)
Origin and Breeding Controlled pollination: seed parent
“unnamed seedling” x pollen parent “unnamed seedling”.
Both parents are breeding stock plants within breeder’s
private collection. Hybridisation took place in Quito,
Ecuador in 1994. From this cross, the seedling was chosen
in 1995 on the basis of flower colour. Selection criteria:
suitable habit and production in greenhouse conditions for
cut flower production. Propagation: a number of mature
stock plants were generated from this seedling through
vegetative cuttings and grafted and budded onto a rootstock
and were found to be uniform and stable. ‘Panroug’ will be
commercially propagated by vegetative cuttings and grafted
and budded onto a rootstock from the stock plants. Breeder:
Mr. A.A. Pouw, Quito, Ecuador.
