Origin & Breeding History: 'Kakegawa S71' originated from a hybridization conducted in February of 2000 in Kakegawa, Japan. The female parent was an unnamed breeding line with red orange flowers and semi-creeping plant growth habit and the male parent was variety 'Kakegawa S52' (Liricashower Coral Vein). In August of 2000, F1 seed was sown and eighty of the resulting seedlings were transplanted outdoors. One plant was selected for vegetative propagation based on its semi-creeping plant growth habit and light orange corolla with red orange mid-veins. In February of 2001, this selection was re-propagated vegetatively for evaluation in 9 cm hanging pots grown in greenhouse and open field trials. Using new vegetatively propagated plants, the selection was further evaluated in Salinas, California, USA. When it was determined that the characters were firmly fixed, the selection was named 'Kakegawa S71'.
Tests & Trials: The test and trial for 'Kakegawa S71' was conducted in a polyhouse at Variety Rights Management in Oxford Station, Ontario during the summer of 2005. The trial included 15 plants of each variety grown in 10 cm pots. The plants were spaced 13 cm apart. All colour characteristics were determined using the 2001 Royal Horticultural Society (RHS) colour chart and measured characteristics were based on ten measurements.
