Abstract

A new and distinct cultivar of Geranium plant named ‘Cante Coras’, characterized by its upright, outwardly spreading and mounded growth habit; freely basal branching habit; dark green-colored leaves; freely flowering habit with many flower umbels per plant; flower umbels with numerous coral red-colored single flowers; and resistance to leaf oedema.

Description

Botanical classification/cultivar designation: Pelargonium×hortorum×Pelargonium tongense cultivar Cante Coras.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium plant, botanically known as Pelargonium×hortorum×Pelargonium tongense, commercially known as an interspecific Geranium, and hereinafter referred to by the name ‘Cante Coras’.

The new Geranium is a product of a planned breeding program conducted by the Inventor in Gilroy, Calif. The objective of the breeding program is to develop new Geranium cultivars with mounded plant habit, good basal branching, large flowers, attractive flower and foliage coloration and resistance to leaf oedema.

The new Geranium originated from a cross-pollination made by the Inventor in October, 1996 of a proprietary Pelargonium×hortorum×Pelargonium tongense selection identified as code number 6271-5, not patented, as the female, or seed, parent with a proprietary Pelargonium×hortorum×Pelargonium tongense selection identified as code number 6828-5, not patented, as the male, or pollen, parent. The cultivar Cante Coras was discovered and selected by the Inventor as a flowering plant within the progeny from this cross-pollination in a controlled environment in Gilroy, Calif. in March, 1997.

Asexual reproduction of the new cultivar by terminal cuttings at Gilroy, Calif., since March, 1997 has shown that the unique features of this new Geranium are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Cante Coras’. These characteristics in combination distinguish ‘Cante Coras’ as a new and distinct Geranium cultivar:

• • 1. Upright, outwardly spreading and mounded growth habit.
  • 2. Freely basal branching habit.
  • 3. Dark green-colored leaves.
  • 4. Freely flowering habit with many flower umbels per plant.
  • 5. Flower umbels with numerous coral red-colored single flowers.
  • 6. Resistant to leaf oedema.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Geranium differed from plants of the female parent selection in the following characteristics:

• • 1. Plants of the new Geranium were more vigorous than plants of the female parent selection.
  • 2. Plants of the new Geranium had darker green-colored leaves than plants of the female parent selection.
  • 3. Plants of the new Geranium and the female parent selection differed in flower color as plants of the female parent selection had red-colored flowers.

In side-by-side comparisons conducted in Gilroy, Calif., plants of the new Geranium differed from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Geranium had darker green-colored leaves than plants of the male parent selection.
  • 2. Plants of the new Geranium and the male parent selection differed in flower color as plants of the male parent selection had red-colored flowers.

The new Geranium can be compared to the cultivar, Balgalsusi, disclosed in U.S. Plant Pat. No. 12,474. However, in side-by-side comparisons conducted in Gilroy, Calif., plants of the new Geranium differed from plants of the cultivar Balgalsusi in the following characteristics:

• • 1. Plants of the new Geranium were more densely foliated than plants of the cultivar Balgalsusi.
  • 2. Plants of the new Geranium had shorter peduncles than plants of the cultivar Balgalsusi.
  • 3. Flowers of plants of the new Geranium were lighter in color than flowers of plants of the cultivar Balgalsusi.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Cante Coras have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype. The aforementioned photographs and following observations and measurements describe plants grown in Gilroy, Calif., under commercial practice in a polyethylene-covered greenhouse during the late spring with day temperatures about 27 to 29° C., night temperatures about 16 to 18° C. and light levels about 2,000 foot-candles. Plants used for the photographs and description were about five months from planting rooted cuttings. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
