Variety used for comparison: 'Explorer Pink'

Summary: 'Kakegawa S84' is a petunia variety which has flowers that are a lighter pink colour than the flowers of 'Explorer Pink'.


'Kakegawa S84' is a petunia variety which has plants with a creeping growth habit. The shoots are medium in thickness, short to medium in length, with no anthocyanin colouration. The leaf blade is elliptic to ovate in shape, with a broad acute apex. The upper side is medium green and has no variegation or blistering. The sepals are linear to lanceolate in shape and have no anthocyanin colouration.

'Kakegawa S84' has single, blue pink flowers which are funnel form in shape. There are moderately conspicuous, pink purple veins on the inner side of the corolla. The corolla margin is weakly to moderately undulating. The corolla tube is purple with moderately conspicuous veins. Before dehiscence the anthers are light grey to yellowish white.

Origin & Breeding History: 'Kakegawa S84' originated from a hybridization first conducted in Kakegawa, Japan in 1993. The male parent was a proprietary Petunia breeding line named 001-93 and had a medium flower size and pink flower colour. The female parent was a proprietary Petunia breeding line named 002-93 and had a magenta flower colour and a creeping growth habit. An F1 and F2 generation from the initial hybridization was grown. Segregation in the F2 resulted in plants that had either pink or magenta flower colour, medium or small flower size, and either a creeping, mounding or cascading growth habit. An F3 generation was produced. From the F3 generation, the breeder selected plants that exhibited a pink flower colour and a creeping growth habit. These selections were then crossed to produce several rounds of sexual propagation for the purpose of fixing desirable traits through successive generations of sexual reproduction. The F10 generation resulted in a sexually reproduced Petunia line with pink flower colour and creeping growth habit. Another hybridization was performed using this selection as the male parent and another proprietary Petunia breeding line, with a medium flower size and light pink flower colour, named 003-93, as the female parent. The F1 hybrid generation all had a medium flower size and light pink flower colour. One was selected and named 'Explorer Pink'. In 2003, a single-plant selection was made from 'Explorer Pink' in Salinas, California. This selection had a pink flower with red inner corolla throat and tube. The selection was named 'Kakegawa S84'.

Tests & Trials: Tests and trials for 'Kakegawa S84' were conducted in Oxford Station, Ontario during the summer of 2005. The trials consisted of 15 plants of each variety, grown in 10cm square pots in a polyhouse. The pots were placed in flats and spaced approximately 15 to 20 cm apart. All colour determinations were made using the RHS Colour Chart 2001.
