Origin & Breeding History: 'Kakegawa S62' originated from a cross made in November 1998 in Kakegawa, Japan. The female parent was calibrachoa 'Colorburst Cherry' and the male parent was the calibrachoa breeding line 97-1176. In February 1999, F1 seed was sown from this cross and planted outdoors. Three plants with red flower colour were selected and intercrossed to produce F2 generation seed. In August 1999, 100 lines of the F2 seed were grown outdoors. The F2 plants ranged from extra compact to mounding habit, as well as being either rose or red in flower colour. Two plants were selected for their red flower colour and extra compact habit and were vegetatively propagated. In February 2002, these two selections were evaluated in hanging 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 Salinas, California, USA during 2003.
Tests & Trials: Test and trials for 'Kakegawa S62' were conducted during the summer of 2005 at Oxford Station, Ontario. 15 plants of each variety were individually grown in 10 cm pots in a polyhouse. 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.
