plant named ‘SAKPXC005’

Abstract

‘SAKPXC005’ is a new Petunia-Calibrachoa hybrid particularly distinguished by having a vanilla and blue-purple flower color and medium to large flower size.

Description

Genus and species: Petunia-Calibrachoa hybrid.

Variety denomination: ‘SAKPXC005’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Petunia-Calibrachoa hybrid referred to by the variety name ‘SAKPXC005’. Variety ‘SAKPXC005’ originated from a hybridization in Kakegawa, Japan in October of 2004. The male parent was a proprietary hybrid Calibrachoa line named ‘04-94’, which had a bronze with vein flower color, medium-large flower size and a creeping plant habit. The female parent was a proprietary hybrid Petunia line named ‘04F-31 K’, which had a pink with eye flower color, medium flower size and a semi-mounding plant habit.

In October 2004, the new Petunia-Calibrachoa variety was developed using an intergeneric cross between Petunia hybrida and a Calibrachoa hybrida species. After crossing the parent lines, 1,500 ovules were removed from flowers on the female parent and cultured by standard ovule culture techniques. In December 2004, one intergeneric hybrid plantlet was transplanted to soilless media for greenhouse culture and acclimatization.

In April 2005, the selected plant was vegetatively propagated by cuttings to produce rooted cuttings. The selected plant was transplanted to an open field and evaluated for flower color and plant growth habit through July 2005. The selected plant, named ‘SAKPXC005’, has a vanilla and blue-purple with vein flower color, medium-large flower size and a mounding plant habit. From August to November 2005, ‘SAKPXC005’ was vegetatively propagated and transplanted into a field. In November 2005, ‘SAKPXC005’ was found to reproduce true to type in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Kakegawa, Japan.

• • 1. Vanilla and blue-purple flower color;
  • 2. Medium to large flower size; and
  • 3. A mounding plant growth habit.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘SAKPXC005’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. The detailed description was taken from plants grown under greenhouse conditions for approximately five and a half months from transplanting of rooted cuttings. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4^th Edition.

• 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 four 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. For the first week, the cuttings were misted with water from overhead for 20 seconds, one time per hour. For the second week, the cuttings were misted one time every 2 hours for 10 seconds. After that time, the cuttings were misted occasionally until sufficient roots were formed. Rooted cuttings were transplanted and grown 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 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.

COMPARISON WITH PARENTAL LINES AND KNOWN CULTIVARS

‘SAKPXC005’ is a distinct variety of Petunia-Calibrachoa due to its vanilla and blue-purple flower color and mounding growth habit. ‘SAKPXC005’ is distinguished from its parents mainly by flower color and plant growth habit as shown in Table 1 below.

‘SAKPXC005’ is a distinct variety of Petunia-Calibrachoa due to its vanilla and blue-purple flower color. ‘SAKPXC005’ is most similar to the variety ‘Kakegawa S91’ (U.S. Plant Pat. No. 19,122); however, there are differences in the petal color as described in the table below (color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4^th Edition):
