USPP28590P2 - New Guinea Impatiens plant named ‘SAKIMP039’ - Google Patents

Abstract

An Impatiens plant particularly distinguished by having red flowers with red-purple eyes, and a compact plant habit, is disclosed.

Description

Genus and species: Impatiens×hybrida hort.

Variety denomination: ‘SAKIMP039’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of New Guinea impatiens plant, botanically known as Impatiens×hybrida hort, and referred to by the variety name ‘SAKIMP039’. ‘SAKIMP039’ originated from an interspecific hybridization in Misato, Japan between the proprietary female Impatiens line ‘NH-248-13H’ (unpatented) and the proprietary male Impatiens line ‘NH-312-36KH’ (unpatented).

In June 2011, the parental lines were crossed and a population of F1 plants was created. The F1 plants were evaluated in Misato, Japan in an open-field trial. The criteria for plant selection included deep flower color and vigorous rooting. At the completion of the trial, one single plant selection designated ‘M2013-191’ was made based on the above criteria and vegetatively propagated. From June to August 2013, the selection was evaluated in an open-field in Misato, Japan. Shoot-tip cuttings of the variety were then shipped to Salinas, Calif., where the plants were regenerated and re-evaluated for stability of traits. The selection, subsequently named ‘SAKIMP039’, was found to reproduce true to type in successive generations of asexual propagation via shoot-tip 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. Red flowers with red-purple eyes; and
  • 2. A compact plant habit.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKIMP039’. Color references are to The Royal Horticultural Society of London Colour Chart (R.H.S.), 4^th edition (2001). Data was collected from plants grown about 7 months from propagation by terminal cuttings in Salinas, Calif. under greenhouse conditions. Anatomic labels are from The Cambridge Illustrated Glossary of Botanical Terms, by M. Hickey and C. King, Cambridge University Press.

• Classification:
  • • Family.—Balsaminaceae.
    • Botanical.—Impatiens×hybrida hort.
    • Common.—Impatiens.
    • Designation.—‘SAKIMP039’.
• 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.
