| Abstract: |
A new and distinct cultivar of Nemesia plant named `Balarwite` characterized by its white-colored flowers, floriferousness, and compact, upright growth habit. |
| Claim: |
What is claimed is:
1. A new and distinct cultivar of Nemesia plant named `Balarwite`, substantially as herein shown and described. |
| Description: |
Latin name of genus and species of plant claimed: Nemesia caerulea.
Variety denomination: `Balarwite`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Nemesia plant botanically known as Nemesia caerulea and hereinafter referred to by the cultivar name `Balarwite`.
The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during August 2002. The objective of the breeding program was the development of Nemesia cultivars with unique flower colors, continuous flowering, and awell-branched growth habit.
The new cultivar is the result of open pollination with the female (seed) parent being the proprietary Nemesia caerulea breeding selection designated NEM-214, not patented, characterized by its white-colored flowers, medium green-colored foliage,and medium upright growth habit. The male (pollen) parent of the new cultivar is unknown. The new Nemesia was discovered and selected by the inventor as a single flowering plant within the progeny of the above stated open-pollination during November2002 in a controlled environment at Arroyo Grande, Calif.
Asexual reproduction of the new cultivar by terminal stem cuttings since November 2002 at Arroyo Grande, Calif. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all characteristics, as herein described,firmly fixed and retained through successive generations of such asexual propagation.
SUMMARY OF THE INVENTION
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish `Balarwite` as a new and distinct cultivar of Nemesia plant: 1. White-colored flowers; 2. Floriferousness; and 3. Compact, uprightgrowth habit.
Plants of the new cultivar differ from plants of the female parent primarily in growth habit.
Of the many commercially available Nemesia cultivars known to the inventor, the most similar in comparison to the new cultivar is `Balarcomwhit`, U.S. Plant Pat. No. 15,459. However, in side by side comparisons, plants of the new cultivardiffer from plants of `Balarcomwhit` in the following characteristic: Plants of the new cultivar are more compact than plants of `Balarcomwhit` as measured by plant height, internode length, and pedicel length.
BRIEF DESCRIPTION OF THEPHOTOGRAPHS
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 fromthe color values cited in the detailed description, which accurately describes the colors of `Balarwite`. The plants were grown in 10 cm pots for 10 weeks in a greenhouse at West Chicago, Ill.
FIG. 1 illustrates a side view of the overall growth and flowering habit of `Balarwite`.
FIG. 2 illustrates a close-up view of a single flower of `Balarwite`.
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 daylength, without, however, any variance in genotype.
The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2001 edition, except where general color terms of ordinary significance are used. The color valueswere determined on Apr. 4, 2005 between 3:00 p.m. and 4:00 p.m. under natural light conditions, in West Chicago, Ill.
The following descriptions and measurements describe plants produced from cuttings taken from stock plants and grown in a double polycarbonate-covered greenhouse under conditions comparable to those used in commercial practice. The plants weregrown at West Chicago, Ill. in 10 cm pots for 10 weeks utilizing a soilless growth medium. Greenhouse temperatures were maintained at approximately 65.degree. F. to 75.degree. F. (18.degree. C. to 24.degree. C.) during the day and approximately50.degree. F. to 60.degree. F. (10.degree. C. to 15.degree. C.) during the night. Greenhouse light levels of 4,000 to 7,000 footcandles were maintained during the day. Botanical classification: Nemesia caerulea cultivar Balarwite.
