Variety Description

Varieties used for comparison: 'Mediopimo' (Supertunia Mini Bright Pink) and 'Constraw' (Mini Strawberry Pink Veined)

Summary: 'MP209' is a petunia variety which has slightly smaller leaves than 'Constraw' and significantly smaller leaves than 'Mediopimo'. The corolla of 'MP209' is smaller in diameter than the corolla of the reference varieties. The veins on the upper side of the corolla of 'MP209' are weakly to moderately conspicuous, whereas the veins on the corolla of 'Constraw' are very strongly conspicuous. The corolla tube of 'MP209' is violet on the inner side, while the corolla tube of 'Mediopimo' is light yellow,with the colour extending onto the corolla lobes at the transition to the tube.

Description:

PLANT: creeping growth habit
SHOOT: medium thickness, short to medium length, no anthocyanin colouration

LEAF: elliptic shape, broad acute apex, no variegation, medium green on upper side, blistering absent

SEPAL: linear to obovate shape, no anthocyanin
FLOWER: single, funnel form
COROLLA LOBE: one colour on upper side, blue pink, weakly to moderately conspicuous purple veins, medium undulation of margin
COROLLA TUBE: violet on inner side, moderately conspicuous veins
ANTHER: yellowish white before dehiscence

Origin & Breeding History: 'MP209' was developed from a Petunia × hybrida breeding program located at the University of Sydney Plant Breeding Institute Cobbitty (PBIC), in Cobbitty, New South Wales, Australia. This vegetative breeding program is aimed at producing compact but spreading, small flowered petunia varieties. The parents 'X01.85.1' (female) and 'X01.131.1' (male) were crossed in December 2001. These parents were crossbreeds from the proprietary program. The new variety was selected from the F1 seedling population in October 2002 and was tested for uniformity and stability in tissue culture propagation. The initial selection criteria were for flower colour, early flowering and habit.

Tests & Trials: Trials for 'MP209' were conducted in a polyhouse at Oxford Station, Ontario during the summer of 2006. The trials consisted of 15 plants of each variety, planted in 15 cm pots and spaced at approximately 30 cm apart on the bench. Observations and measurements were taken from 10 plants of each variety. Colour determinations were done using the 2001 Royal Horticultural Society (RHS) Colour Chart.
