Description

Genus and species: Impatiens hybrida hort.

Variety denomination: ‘SAKIMP037’.

BACKGROUND OF THE NEW PLANT

The present invention comprises of a new and distinct cultivar of New Guinea Impatiens, botanically known as Impatiens hybrida hort, and referred to by the variety name ‘SAKIMP037’. ‘SAKIMP037’ originated from an interspecific hybridization between Impatiens ‘NE-4391’, an unpatented proprietary white flowered Impatiens breeding line and Impatiens ‘NF-4858’, an unpatented proprietary scarlet flowered Impatiens breeding line in Misato, Japan.

In September 2009, the female parent line ‘NE-4391’ and male parent line ‘NF-4858’ 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 compact growth habit, vigorous rooting, bright flower color and variegated leaves. At the completion of the trial, one single-plant selection was made based on the above criteria and vegetatively propagated. From June to August 2012, 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 ‘SAKIMP037’ and found to have its unique characteristics 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 flowers; and
    • 2. Green leaves with yellow variegation.

CROSS-REFERENCE TO RELATED APPLICATIONS

  • Classification and parentage:
      • Family.—Balsaminaceae.
      • Botanical.—Impatiens hybrida hort.
      • Common.—Impatiens.
      • Designation.—‘SAKIMP037’.
      • Parentage.—Female Parent: Proprietary Impatiens plant line ‘NE-4391’. Male Parent: Proprietary Impatiens plant line ‘NF-4858’.
  • 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.
