-hybrid plant named ‘SAKPXC016’

Abstract

A new Petunia-Calibrachoa hybrid plant particularly distinguished by having pink flower color with darker pink veins and a yellow throat and a spreading plant habit, is disclosed.

Description

Genus and species: Petunia-Calibrachoa intergeneric hybrid.

Variety denomination: ‘SAKPXC016’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Petunia-Calibrachoa (Petchoa) referred to by the variety name ‘SAKPXC016’. ‘SAKPXC016’ originated from a hybridization in Kakegawa, Japan in December 2009 between the proprietary female Petunia line ‘AM6-81A-1A-1A-1A’ (unpatented) and the proprietary male Calibrachoa line ‘8B-43A-V1’.

In January 2010, an F1 generation from the initial hybridization was grown and approximately 41 seeds were obtained. In July 2010, 6 plants from the F1 generation of seeds were cultivated in a greenhouse. F1 plants exhibited pink and lavender flower colors with mounding and semi-mounding habits. In July 2010, a single plant was selected and designated ‘K2011-J-120’ which had pink flowers with a yellow eye color, vigorous blooming, and a mounding habit. In August 2010, the selection was first vegetatively propagated to produce rooted cuttings and plants of the selection were cultivated and evaluated in an open field. In November 2010, the selection was observed to have its distinctive characteristics remain stable. In December 2010, the selection was propagated again and plants were cultivated. In April 2011, ‘K2011-J-120’ was observed to have its distinct characteristics remain stable. ‘K2011-J-120’ was confirmed that the distinct characteristics of the plant were fixed and stable. All breeding work was conducted at the Kakegawa research station in Kakegawa, Japan. ‘K2011-J-120’ was later named ‘SAKPXC016’ and was found to reproduce true to type in successive generations of asexual propagation via vegetative cuttings in Salinas, Calif.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Salinas, Calif.

• • 1. Pink flower color with darker pink veins and a yellow throat; and
  • 2. A spreading plant habit.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKPXC016’. Color references are to The R.H.S.

• Classification:
  • • Family.—Solanaceae.

    • Common.—Petchoa, petunia-calibrachoa.
    • Designation.—‘SAKPXC016’.
• Growth:
  • • 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 solution: 9 water), a 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 10 seconds every 30 minutes 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.
