plant named ‘SAKCAL107’

Abstract

A Calibrachoa plant particularly distinguished by having a yellow flower color and a compact plant growth habit, is disclosed.

Description

Genus and species: Calibrachoa spp.

Variety denomination: ‘SAKCAL107’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Calibrachoa plant, botanically known as Calibrachoa spp., and referred to by the variety name ‘SAKCAL107’. ‘SAKCAL107’ originated from a hybridization in Kakegawa, Japan in 2008 between the female Calibrachoa line ‘7-1A’, an unpatented proprietary hybrid Calibrachoa breeding line having a scarlet red flower color and mounding growth habit and the male Calibrachoa line ‘6dw-54A-2’, an unpatented proprietary hybrid Calibrachoa breeding line with a yellow flower color and compact growth habit.

In November 2008, the female parent line ‘7-1A’ and the male parent line ‘6dw-54A-2’ were crossed and 200 seeds were obtained. In February 2008, the F₁ seed were sown in a greenhouse, cultivated, and plant lines were produced with flower colors of yellow, rose, and purple having a compact and mounding growth habit. Two plant lines were selected within the F₁ plants that had yellow and purple flowers and a compact growth habit. The two F₁ plant lines were intercrossed and 900 seeds were obtained.

In July 2008, 600 seeds were sown in the greenhouse, cultivated, and plant lines were produced with flower colors of rosy red, yellow, purple, and brown and a compact growth habit. A single plant was selected that had a yellow flower color and a compact growth habit and designated ‘K2009-088’.

In February 2009, ‘K2009-088’ was vegetatively propagated, cultivated, and evaluated. In April 2009, ‘K2009-088’ was confirmed to be fixed and stable. ‘K2009-088’ was further propagated and cultivated to reconfirm the line's stability. ‘K2009-088’ was subsequently designated ‘SAKCAL107’ and found to have its unique characteristics reproduce true to type in successive generations of asexual vegetative propagation via vegetative cuttings.

SUMMARY

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

• • 1. Yellow flower color; and
  • 2. A compact plant growth habit.

DESCRIPTION OF THE PHOTOGRAPHS

This Calibrachoa plant is illustrated by the accompanying photographs which show the plant's overall plant habit including form, foliage, and flowers. The photographs are of a four-month-old plant grown in Salinas, Calif. under greenhouse conditions in the summer of 2012. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKCAL107’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. Data was collected on four-month-old plants grown under greenhouse conditions in Salinas, Calif. in the summer of 2012. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4^th edition (2001).

• Growth:
  • • Time to produce a rooted cutting.—About 6 weeks.
    • 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) 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-cm diameter plastic pots in a glass greenhouse located in Salinas, California. 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.
