Origin and Breeding Controlled pollination: seed parent
breeder’s code PAS36117 x pollen parent ‘Temari Hot Pink’
in a planned breeding program in Arroyo Grande,
California. The seed parent is characterised by semi-trailing
plant habit, serrated leaf margin, and dark purple flower
colour. The pollen parent is characterised by vigorous
trailing plant habit and hot pink flower colour. ‘Balazplum’
was selected from the seedling progeny of this cross in 1998
in Arroyo Grande, California, USA. Selection criteria: plant
habit, leaf size and colour, flowering habit, flower colour.
Propagation: vegetative tip cuttings. ‘Balazplum’ has been
found to be uniform and stable through many generations
since selection. Breeder: Dr Scott Trees, Ball FloraPlant,
Arroyo Grande, California, USA.
Choice of Comparators Grouping characteristics used in
identifying the most similar varieties of common
knowledge were – Flower: type single, bud colour purple,
and main colour of upper side of petals purple. On the basis
of these grouping characteristics the following varieties
were included in the trial: ‘Sunmarefu TP-V A syn Purple
Passion A , ‘Sunmariba’ A syn Violet Surprise A , ‘Sunmarefu
TP-L’ A syn Lilac Reflections A . For the purpose of
providing evidence of breeding, the parent material can be
clearly distinguished from the candidate variety using the
grouping characteristics – Leaf: shape and Plant: habit.
Comparative Trial Location: Winmalee, NSW, Sep-Dec
2001. Conditions: trial conducted in out door production
area, rooted cuttings (propagated from stock plants grown at
Winmalee) potted in Sep into 150mm standard pots in
commercial potting mix, nutrients supplied by slow release
and liquid feed fertiliser applications, plant protection
treatments applied as necessary. Trial design: 10 pots of
each variety arranged in a completely randomised design.
Measurements taken from 10 plants per variety selected at
random (one sample per plant).
