Abstract

‘Kakegawa S63’ is a new variety of Calibrachoa plant. This new variety has red-purple petal lobes with purple petal lobe veins and dark green foliage.

Description

Genus/species: Calibrachoa species.
Varietal denomination: ‘Kakegawa S63’.
BACKGROUND OF THE INVENTION
‘Kakegawa S63’ originated from a hybridization made in November 1998 in Kakegawa, Japan. The female parent was a Calibrachoa breeding line with a deep blue flower color and mounding habit known as 8B-48 (not patented). The male parent was a Calibrachoa breeding line with deep rose colored flowers and mounding habit and short internode length known as 97-1176 (not patented).
In February 1999, F1 seed from this cross was sown and later transplanted outdoors. The F1 plants were rose, magenta or blue in flower color and ranged from semi-creeping to compact in habit. Three, single-plant selections were made from the F1 generation and vegetatively propagated. In February 2002, these selections were evaluated in 9 cm hanging pots in a greenhouse as well as in an open field. One selection was chosen based on the trial.
The selection was further evaluated from new vegetative plants in Salinas, Calif. during 2003. The selection was subsequently named ‘Kakegawa S63’ ‘Kakegawa S63’ was asexually reproduced by stem cuttings in Salinas, Calif. and was determined to reproduce true to type in successive generations of asexual propagation.
DESCRIPTION OF PHOTOGRAPH
This new Calibrachoa plant is illustrated by the accompanying photograph which shows 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 GENUS CALIBRACHOA LLAVE & LEX
The genus Petunia was originally established in 1803 by A. L. Jussieu, who described both P. parviflora and P. nyctaginiflora as type species. Using a non-horticultural system that selected the first mentioned species as the type species (lectotype), N. L. Britton and H. A. Brown declared P. parviflora as the type species for Petunia in 1913.
During the 1980's and 1990, H. J. Wijsman published a series of articles regarding the ancestry of P. hybrida, the Garden Petunia, and the inter-relationship of several species classified as Petunia. These studies discovered that P. hybrida and its ancestral species, P. nyctaginiflora (=P. axillaris) and P. violacea (=P. integrifolia), possessed 14 pairs of chromosomes while several other species, including P. parviflora, possessed 18 pairs of chromosomes. Since P. parviflora was the lectotype species for the Petunia genus, Wijsman and J. H. de Jong proposed transferring the 14 chromosome species to the genus Stimoryne. Horticulturists opposed reclassifying the Garden Petunia and in 1986, Wijsman proposed the alternative of making P. nyctaginiflora the lectotype species for Petunia and transferring the 18 chromosome species to another genus. The I. N. G. Committee adopted this proposal. By 1990, Wijsman had transferred several species, including P. parviflora (=C. parviflora) to Calibrachoa, originally established by Llave and Lexarza in 1825. Calibrachoa parviflora (=C. mexicana Llave & Lexarza) is now the type species for the genus Calibrachoa.
Classification of the current Petunia and Calibrachoa species is still in progress. New species are also being identified. Consequently, a proper description has not been written for the Calibrachoa genus. Calibrachoa can, however, be distinguished from Petunia based on the higher chromosome number, chromosome morphology, plant branching habit and type of flower bud aestivation. Whereas Petunia species bear a flower peduncle and one new stem from a node, Calibrachoa bear a flower peduncle and three stems. Petunia species have a cochlear corolla bud, a single outermost petal covers the other four, radially folded and terminally contorted petals. Calibrachoa flower buds are flat with all five petals linearly folded and the two lower petals forming a cover around the three other petals and fused together.
ENVIRONMENTAL CONDITIONS FOR PLANT 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 DIP 'N GROW: 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 seconds every 30 minutes until sufficient roots were formed.
Rooted cuttings were transplanted and grown in 20.0 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 irrigation. 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.
