Abstract

A Petunia plant particularly distinguished by having burgundy and white star patterned flowers and a semi-trailing, and mounding habit, is disclosed.

Description

Genus and species: Petunia hybrida.

Variety denomination: ‘SAKPET105’.

BACKGROUND OF THE NEW PLANT

The present invention comprises of a new and distinct cultivar of Petunia, botanically known as Petunia hybrida, and hereinafter referred to by the cultivar name ‘SAKPET105.’ ‘SAKPET105’ characterized by having a burgundy and white star pattern and mounding plant habit. ‘SAKPET105’ originated from a hybridization in Kakegawa, Japan in 2013. The female parent was a proprietary Petunia breeding line named ‘2ExTr-111a-V1’ (unpatented) having a rose star pattern and a semi-mounding plant habit. The male parent was a proprietary Petunia breeding line named ‘2ExTr-111a-V2’ (unpatented) having a rose star pattern and a semi-mounding plant habit.

In June 2013, ‘2ExTr-111a-V1’ and ‘2ExTr-111a-V2’ were crossed in Kakegawa, Japan and 300 seeds were obtained. In February 2014, the F₁seed was sown in the greenhouse, cultivated and 140 plants were produced with flower colors of rose star pattern and rose with mounding, semi-mounding, and semi-creeping plant habits. In June 2014, five plant lines were selected within the F₁plants that both had burgundy and white start pattern flowers and a mounding plant growth habit. A selection named ‘L2015-PT032’ was selected from these plant lines. From February to March 2015, ‘L2015-PT032’ was evaluated for day length neutral flowering response. From March to May 2015, ‘L2015-PT032’ was vegetatively propagated, cultivated and transplanted to the field for outdoor evaluation. From June to October 2015, the final selections were chosen and the mother stock was established. In January 2016, the breeder confirmed the line to be fixed and stable. The line was subsequently named ‘SAKPET105’ and its unique characteristics were found to reproduce true to type in successive generations of asexual propagation.

SUMMARY

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

- 1. Burgundy and white star patterned flowers; and
- 2. A semi-trailing, and mounding habit.

DESCRIPTION OF THE PHOTOGRAPHS

This Petunia plant is illustrated by the accompanying photographs which show the plant's overall plant habit including form, foliage, and flowers. The photographs are of plants grown 3-months from transplant into 8-inch pots from rooted cuttings in Salinas, Calif. under greenhouse conditions. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

FIG. 1 shows the overall plant habit of the plant grown in a pot.

FIG. 2 shows a close-up of the mature flower of the plant.

DESCRIPTION OF THE NEW VARIETY

The following traits and characteristics describe the new variety. Data obtained from plants grown 3-months from transplant into 8-inch pots from rooted cuttings in Salinas, Calif., under greenhouse conditions. Plants were pinched once during growth. Color references are to The Royal Horticultural Society of London color chart (R.H.S.), 4^thedition (2001). Anatomic labels are from The Cambridge Illustrated Glossary of Botanical Terms, by M. Hickey and C. King, Cambridge University Press.

Classification:
- - Family.—Solanaceae.
  - Botanical.—Petunia hybrida.
  - Common.—Petunia.
  - Designation.—‘SAKPET105’.
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 for 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, 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.
