BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Phalaenopsis plant, botanically known as Phalaenopsis hybrida, and hereinafter referred to by the name ‘Hot Chilli’.
The new Phalaenopsis plant is a product of a planned breeding program conducted by the Inventor in De Lier, Heemskerk and Assendelft, The Netherlands. The objective of the breeding program is to develop new fast-growing and freely flowering Phalaenopsis plants with good leaf shape and flowers with unique and attractive patterns and coloration.
The new Phalaenopsis plant originated from a cross-pollination in May 2013 in De Lier, The Netherlands of a proprietary selection of Phalaenopsis hybrida identified as code number CX355, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number 0109100, not patented, as the male, or pollen, parent. The new Phalaenopsis plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Heemskerk, The Netherlands in October 2018.
Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Assendelft, The Netherlands since October 2019 has shown that the unique features of this new Phalaenopsis plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Phalaenopsis have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hot Chilli’. These characteristics in combination distinguish ‘Hot Chilli’ as a new and distinct Phalaenopsis plant:
- 1. Upright plant habit.
- 2. Moderately vigorous growth habit.
- 3. Strong flowering stems.
- 4. Strong leaves.
- 5. Freely flowering habit with typically two inflorescences developing per plant, each inflorescence with numerous flowers.
- 6. Flowers with dark purplish red-colored petals and sepals.
- 7. Flowers with white, reddish purple and yellow-colored labella.
- 8. Good postproduction longevity.
Plants of the new Phalaenopsis can be compared to plants of the female parent selection. Plants of the new Phalaenopsis differ primarily from plants of the female parent selection in the following characteristics:
- 1. Flower petals and sepals of plants of the new Phalaenopsis are dark purplish red in color whereas flower petals and sepals of plants of the female parent selection are soft violet in color.
- 2. Flower petals of plants of the new Phalaenopsis have a few stripes and no dots whereas flower petals of plants of the female parent selection have a moderate amount of stripes and dots.
Plants of the new Phalaenopsis can be compared to plants of the male parent selection. Plants of the new Phalaenopsis differ primarily from plants of the male parent selection in the following characteristics:
- 1. Flower petals of plants of the new Phalaenopsis are not imbricate whereas flower petals of plants of the male parent selection are very close to imbricate.
- 2. Labella of the plants of the new Phalaenopsis are white, reddish purple and yellow in color whereas labella of plants of the male parent selection are solid purplish red in color.
Plants of the new Phalaenopsis can be compared to plants of x Doritaenopis (Doritis X Phalaenopsis) ‘Bulls Eye’, disclosed in U.S. Plant Pat. No. 34,645. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘Bulls Eye’ in the flower color as labella of the plants of the new Phalaenopsis are white, reddish purple and yellow in color whereas labella of plants of ‘Bulls Eye’ are solid purple in color.

DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the early spring in 10.5-cm containers in a glass-covered greenhouse in Heemskerk, The Netherlands and under cultural practices typically used in commercial Phalaenopsis production. Plants were 18 months old when the photographs and description were taken. During the first twelve months of production of the plants, day and night temperatures averaged 27° C. During the final six months of production of the plants, day temperatures ranged from 20° C. to 22° C. and night temperatures ranged from 18° C. to 20° C. During the production of the plants, light levels ranged from a minimum of 5,000 lux to a maximum of 10,000 lux.
