Origin and Breeding Controlled pollination: Seed parent
(‘Yellow Cushion’ x ‘Aloha’) x pollen parent ((Chaucer x
‘Aloha’) x (‘Iceberg’ x “Unnamed seedling”)). Selection
criteria: ‘Masdogui’ was selected on the basis of its
flowering habit, flower quality and repeat flowering ability.
Propagation: Seed was harvested, stratified, germinated
then grown to maturity for assessment. Further propagation
was by graft onto a suitable virus indexed rootstocks
through numerous generations. Breeder: Roseraies Pierre
Guillot, Chamagnieu, France during 1997.
Choice of Comparators Grouping characteristics used in
identifying the most similar varieties of common
knowledge were: flower colour and plant habit. Based on
these characteristics ‘AUScot’ A (syn Abraham Darby) was
selected as a comparator because of its similarities in flower
colour and plant habit and is considered the closest variety
of common knowledge. Exclusion of the parents was based
on the following characteristics: ‘Aloha’ climbing plant
habit, ‘Chaucer’ light pink flower colour, ‘Iceberg’ white
flower colour.
Comparative Trial Location: Sevenhill SA, Spring 2001-
Autumn 2002. Conditions: trial conducted in an open field
situation with overhead watering, fertilizing, pest, disease
control and weeding, as necessary. Single budded onto virus
indexed Rosa ‘Dr Huey’ understock. Trial design: 25 plants
or each variety, in blocks. Measurements: taken in Apr 2002
from 20 plants at random.
