Origin & Breeding History: 'Kakegawa S79' originated from a cross made in May 2001 in Kakegawa, Japan. The female parent was calibrachoa breeding line 0B-10AA-1A, and the male parent was the calibrachoa breeding line 9B-8AA-1A. In August 2001, F1 seed was sown from this cross and planted in a greenhouse. Three plants regardless of flower colour or habit were selected and intercrossed to produce F2 generation seed. In February 2002, 100 lines of the F2 seed were grown and evaluated. The F2 plants all had bronze vein flower colour and were either semi-creeping or mounding in habit. Four plants were selected for their bronze vein flower colour and semi-creeping habit and were vegetatively propagated. In the summer of 2002, these four selections were evaluated in 9cm pots in a greenhouse as well as under field conditions. One selection was chosen based on these evaluations and further evaluated from new vegetative plants in August 2002.

Tests & Trials: Test and trials for 'Kakegawa S79' were conducted during the summer of 2006 at Oxford Station, Ontario. 15 plants of each variety were individually grown in 10 cm pots in a poly house. Plants were spaced 13 cm apart. Observations and measurements were taken on 10 plants of each variety. All colour observations were made using the RHS Colour Chart 2001.
