Abstract

‘SAKPXC009’ is a new Petunia-Calibrachoa hybrid plant particularly distinguished by its pink flower color, excellent blooming ability and semi-creeping growth habit.

Description

Genus and species: Petunia-Calibrachoa Hybrid (P.×hybrida×C.×hybrida).

Variety denomination: ‘SAKPXC009’.

BACKGROUND OF THE INVENTION

The present invention comprises of a new and distinct cultivar of Petunia-Calibrachoa (Petchoa) referred to by the variety name ‘SAKPXC009’. Variety ‘SAKPXC009’ originated from an intergeneric hybridization in Kakegawa, Japan in October of 2004. The male parent was proprietary hybrid Calibrachoa line ‘2B-106A-1’, which has a white flower color, large flower size and a creeping plant habit. The female parent was proprietary hybrid Petunia line ‘103K’, which has a rose flower color, medium flower size and semi-mounding plant habit.

After crossing the parent lines, 1600 ovules were removed from flowers on the female parent and cultured by standard ovule culture techniques. In March 2005, intergeneric hybrid plantlets were transplanted to soilless media for greenhouse culture and acclimatization.

From July to November 2005, the plants were vegetatively propagated to produce rooted cuttings. Subsequently, the plants were transplanted to an open field and evaluated for flower color and plant growth habit. A plant was selected that had a pink flower color, an excellent blooming ability and semi-creeping plant growth habit. Plants of the selection were vegetatively propagated and then were evaluated in an open field. In June 2006, the breeder confirmed that the distinct characteristics of the selection were fixed and stable. The selection was named ‘SAKPXC009’. All breeding work was conducted at Kakegawa Research station in Kakegawa Japan.

Plant Variety Protection for this variety was applied for in Japan on Oct. 8, 2010. ‘SAKPXC009’ has not been made publicly available more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

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

• • 1. Pink flower color;
  • 2. Excellent blooming ability; and
  • 3. Semi-creeping growth habit.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘SAKPXC009’. 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 4 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.

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

‘SAKPXC009’ is a new and unique variety of intergeneric Calibrachoa-Petunia owing to its pink flower color, excellent blooming ability and semi-creeping plant growth habit. ‘SAKOST8202’ is distinguished from its parents as described in Table 1.

		Female Parent:	Male Parent:
Characteristic	‘SAKPXC009’	‘103K’	‘2B-106A-1’

‘SAKPXC009’ is most similar to the commercial Calibrachoa-Petunia variety ‘Kakegawa S89’ (U.S. Plant Pat. No. 19,130), commercially known as ‘SuperCal® Neon Rose’; however there are differences in the flower color as described in the Table 2 below (color references are to The Royal Horticultural Society Colour Chart, 4^th edition):
