BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct cultivar of petunia, botanically known as Petunia hybrida, and hereinafter referred to by the cultivar name ‘Kakegawa S84’. ‘Kakegawa S84’ originated from a whole plant off-type of ‘SAIPET93’, an unpatented proprietary petunia plant in Salinas, Calif. in 2003. ‘SAIPET93’ originated from a hybridization between ‘001-93’, a proprietary petunia plant with medium flower size and pink flower color, and ‘002-93’, a proprietary petunia plant with magenta flowers and a creeping growth habit.
F1 and F2 generations resulting from the hybridization were grown. Segregation in the F2 generation resulted in plants that had either pink or magenta flower color, medium or small flower size, and either a creeping, mounding, or cascading growth habit. An F3 generation was produced. From the F3 generation, plants were selected that exhibited a pink flower color and creeping growth habit. The selections were then subjected to several rounds of sexual propagation for the purpose of fixing the desirable traits through successive generations of sexual reproduction. The F10 generation resulted in a sexually reproduced petunia with pink flower color and a creeping growth habit named ‘004-93’.
A second hybridization was performed using ‘004-93’ as the male parent and another proprietary petunia plant with a medium flower size and a light pink flower color named ‘003-93’ as the female parent. The resulting F1 hybrid had a medium flower size and a light pink flower color. The hybrid was named ‘SAIPET93’.
In 2003, a sport of ‘SAIPET93’ was noticed in Salinas, Calif. The sport had a pink with red inner corolla throat and tube. The sport was maintained by way of shoot-tip cuttings in Salinas, Calif. and was observed to have its distinct characteristics remain stable through successive generations of asexual reproduction. The sport was then named ‘Kakegawa S84’. ‘Kakegawa S84’ has been found to retain its distinctive characteristics after three years and five cycles of vegetative propagation.
Plant Breeder's Rights for this cultivar were applied for in Canada on Apr. 19, 2005.
DESCRIPTION OF PHOTOGRAPHS
This new petunia plant is illustrated by the accompanying photographs which show blooms and foliage of the plant in full color, the colors shown being as true as can be reasonably obtained by conventional photographic procedures.
DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of ‘Kakegawa S84’. The data which defines these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on plants in 6 inch pots four months after rooted cuttings were transplanted. Plants were pinched once during growth. Color references are primarily to the RHS Colour Chart of The Royal Horticultural Society of London (RHS) (4th ed). Anatomic labels are from The Cambridge Illustrated Glossary of Botanical Terms, by M. Hickey and C. King, Cambridge University Press.
DETAILED BOTANICAL DESCRIPTION
- Botanical.—Petunia hybrida.
- Common name.—Petunia.
- Parentage: Whole plant off-type of ‘SAIPET93’.
- Growth: The terminal 1.0 to 1.5 inches of an actively growing stem was excised. The vegetative cuttings were propagated in five to six weeks. The base of the cuttings were dipped for 1 to 2 seconds in a 1:9 solution of DIP 'N GROW (1 solution: 9 water) root inducing solution immediately prior to sticking into the cell trays. Cuttings were stuck into plastic cell trays having 98 cells, and containing a moistened peat moss-based growing medium. The cuttings were misted with water from overhead for 10 second every 30 minutes until sufficient roots were formed. Plants were propagated from vegetative cuttings, and grown individually in 20 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium was applied once a day or every other day by overhead irrigations. Pots were top-dressed with a dry, slow release fertilizer containing 20% nitrogen, 10% phosphorus and 18% potassium. The typical average air temperature was 24° C.
