Origin & Breeding History: 'MP205' 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 'X01.559.1' (female) and 'X01.81.1' (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 'MP205' 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.
