Genus and species: Calibrachoa sp.
Variety denomination: ‘Cal Scaredtwo’.
BACKGROUND OF THE INVENTIONThe present invention comprises a new and distinct cultivar of Calibracoa, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name ‘Cal Scaredtwo’. The new cultivar originated from a hybridization made in the year 2001 in Gilroy, Calif. The female parent was proprietary Calibrachoa breeding line 328-1 (unpatented) with coral-rose flowers. The male parent was proprietary Calibrachoa breeding line 399-1 (unpatented) with red flowers.
The new cultivar was created in 2001 in Gilroy, Calif. and has been asexually reproduced over a two-year period by vegetative cuttings and tissue culture in Gilroy, Calif. and Andijk, The Netherlands. The plant has also been trialed at Gilroy, Calif., Litchfield, Mich. and Andijk, The Netherlands. ‘Cal Scaredtwo’ has been found to retain its distinctive characteristics through successive asexual propagations. ‘Cal Scaredtwo’ reproduces true to type through successive generations of asexual reproduction.
Description of the genus Calibrachoa Llave & LexThe 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 ancestrial 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 species bear a flower peduncle and three stems. Petunia species have a cochlear corolla bud, a single outermost petal which covers the other four, and radially folded and terminally contorted petals. Calibrachoa flower buds are flat with all five petals linearly folded with the two lower petals forming a cover around the three other petals and fused together.
This new Calibrachoa plant is illustrated by the accompanying photograph which shows blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photograph is of a three-month-old plant grown in a lexan-covered greenhouse.
FIG. 1. shows overall plant habit while the inset photograph show a closer view of the mature inflorescence.
The following detailed descriptions set forth the distinctive characteristics of ‘Cal Scaredtwo’. The data which defines these characteristics were collected from asexual reproductions carried out in Gilroy, Calif. The plant history was taken on four-month-old plants grown in one-gallon pots in a poly-covered greenhouse during the summer season. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001). Texture description data were collected by viewing plant parts with a dissecting microscope.
