Origin & Breeding History: 'MP4' was developed from a Petunia x hybrida breeding program conducted by the breeder in Baulkham Hills, NSW, Australia. In 1993, a program to breed miniature trailing petunias was initiated. A number of smaller flowered petunias including Petunia integrifolia were crossed with a range of annual and double varieties. Two cycles of crossing and selection were undertaken each year until 1997 when promising F1 selections were coded in "A" series. These were crossed in 1997 to give further F1 selections. In 1998, X98.31 as the female parent was crossed with PJ39 as the male parent and given the breeders code X99.3.17. The new variety was selected from field and greenhouse trials during the fall of 1999 based on flower colour, flower size and plant habit.
Tests & Trials: Trials were conducted during the summer of 2006 in Oxford Station, Ontario. 15 plants of each variety were individually grown in 15cm pots in a poly house. Plants were spaced 30cm apart. Observations and measurements were taken on 10 plants of each variety. Colours were determined using the 2001 Royal Horticultural Society Colour Chart.
