Abstract

A New Guinea Impatiens cultivar particularly distinguished by having light pink flowers, large flower petal size, a compact plant habit, and strong root system is disclosed.

Description

Genus and species: Impatiens×hybrida.

Variety denomination: ‘SAKIMP013’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of New Guinea impatiens, botanically known as Impatiens×hybrida (hort), and hereinafter referred to by the cultivar name ‘SAKIMP013’. ‘SAKIMP013’ originated from an interspecific hybridization between ‘NC-229’, an unpatented proprietary pink-lilac flowered Impatiens plant and ‘NC-1H1’, an unpatented proprietary light-orange flowered Impatiens plant, in Misato, Japan.

In January 2004, the female parent line ‘NC-1H1’ and male parent line ‘NC-229’ 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 flower color, strong root system and compact plant growth habit. At the completion of the trial, one single-plant selection was made based on the above criteria and vegetatively propagated. From May to August 2005, 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 reevaluated for stability of traits. The selection subsequently was named ‘SAKIMP013’ and found to have its unique characteristics reproduce true to type in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

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

• • 1. Light pink flowers;
  • 2. Large flower petal size;
  • 3. Compact plant habit; and
  • 4. Strong rooting system.

DESCRIPTION OF PHOTOGRAPHS

This new impatiens plant is illustrated by the accompanying photographs which show overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are 5 months from their transplanting date and 6 months from the stick date.

DETAILED DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘SAKIMP013’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. The plant history was taken on plants grown for about four months from propagation by terminal cuttings under greenhouse conditions. Color references are primarily to the R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4^th edition (2001). Anatomic labels are from The Cambridge Illustrated Glossary of Botanical Terms, by M. Hickey and C. King, Cambridge University Press.

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.
    • Environmental conditions for plant growth.—Rooted cuttings were transplanted and grown in 6-inch 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. Plants were fertilized every 2-3 days, 2 times in consecutive applications and then given one clear water application.
