USPP15529P2 - Interspecific Diascia plant named ‘Balwincor’ - Google Patents

Abstract

A new and distinct Diascia plant named ‘Balwincor’, characterized by its coral-colored flowers, medium green-colored foliage, and spreading and trailing growth habit.

Description

Latin name of genus and species of plant claimed: Diascia barbarae×Diascia integerimma×Diascia mollis.

Variety denomination: ‘Balwincor’.

BACKGROUND OF INVENTION

The present invention relates to a new and distinct Interspecific Diascia plant hereinafter referred to by the cultivar name ‘Balwincor’.

The new cultivar was developed by the inventor in a controlled breeding program during June 2000, at Guadalupe, Calif. The objective of the breeding program was the development of Diascia cultivars with a well-branched, spreading growth habit, continuous flowering and medium green foliage.

The female (seed) parent of ‘Balwincor’ was the proprietary Interspecific Diascia selection designated ‘316-2m-1’ (not patented) characterized by its coral-colored flowers, dark green foliage and bushy growth habit. The male (pollen) parent of ‘Balwincor’ was the proprietary Interspecific Diascia selection designated ‘400-2’ (not patented), characterized by its light lavender-colored flowers, dark green foliage and prostrate growth habit. ‘Balwincor’ was discovered and selected in December, 2000 as a single flowering plant from within the progeny of the above stated cross-pollination and was initially designated ‘593-3m-2-1-1’.

Asexual reproduction of the new cultivar by terminal stem cuttings since December 2000 at Guadalupe, Calif. and West Chicago, Ill., has demonstrated that the new cultivar reproduces true to type with all the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF INVENTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length.

It was repeatedly found that the cultivar of the present invention:

• • 1. Exhibits coral-colored flowers,
  • 2. Forms foliage of a medium green color, and
  • 3. Exhibits a spreading and trailing growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in foliage color and from plants of the male parent primarily in flower and foliage color.

The new cultivar can be compared to the commercially available Diascia variety Sun Chimes Peach(not patented). However, in side by side comparisons, plants of the new cultivar differ from plants of Sun Chimes Peach in the following characteristics:

• • 1. The flowers of the new cultivar are larger,
  • 2. The flowers of the new cultivar are lighter in color, and
  • 3. The leaves of the new cultivar are larger.

BRIEF DESCRIPTION OF PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balwincor’. The plants were grown for 10 weeks in a greenhouse at West Chicago, Ill.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length.

The chart used in the identification of colors described herein is the R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 1995 edition except where general color terms of ordinary dictionary significance are used. The color values were determined on Jul. 23, 2003. The readings were taken between 1:00 and 3:00 p.m. under natural daylight conditions. The plants were produced from cuttings taken from stock plants and were grown in a double polycarbonate covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in 10 cm pots for 10 weeks while utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 62° to 75° F. (17° to 24° C.) during the day and approximately 52° to 60° F. (11° to 15° C.) during the night. Greenhouse light levels were maintained at approximately 5,000-8,000 footcandles during the day.
