Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee.

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 ‘Grand Master’.

The new Phalaenopsis plant is a product of a planned breeding program conducted by the Inventor in Nantou, Taiwan and Heemskerk, The Netherlands. The objective of the breeding program is to develop new fast-growing and freely flowering Phalaenopsis plants with good leaf shape and large flowers with unique and attractive patterns and coloration.

The new Phalaenopsis plant originated from a cross-pollination on Jun. 13, 2014 in Nantou, Taiwan of a proprietary breeding selection identified as Phalaenopsis hybrida ‘Sunrise Red Peoker’ X ‘Sogo Lisa’, not patented, as the female, or seed, parent with Phalaenopsis hybrida ‘Yu Pin Burgundy’, 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 June, 2018.

Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Assendelft, The Netherlands since June, 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 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 ‘Grand Master’. These characteristics in combination distinguish ‘Grand Master’ as a new and distinct Phalaenopsis plant:

• • 1. Upright plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Strong flowering stems.
  • 4. Strong and moderately elongated leaves.
  • 5. Freely flowering habit with typically two inflorescences per plant, each inflorescence with numerous flowers.
  • 6. Dark purplish red-colored flowers with white, violet and yellow-colored labellum.
  • 7. 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 flower color as plants of the new Phalaenopsis have dark purplish red-colored flowers whereas plants of the female parent selection have yellow-colored flowers with numerous stripes.

Plants of the new Phalaenopsis can be compared to plants of the male parent, ‘Yu Pin Burgundy’. Plants of the new Phalaenopsis differ primarily from plants of ‘Yu Pin Burgundy’ in flower color as plants of the new Phalaenopsis have dark purplish red-colored flowers with white, violet and yellow-colored labellum whereas plants of ‘Yu Pin Burgundy’ have burgundy-colored flowers purplish red and cream-colored labellum and numerous spots.

Plants of the new Phalaenopsis can be compared to plants of Phalaenopsis hybrida ‘Scarlet Jubilee’, not patented. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘Scarlet Jubilee’ in plant size as plants of the new Phalaenopsis are shorter than plants of ‘Scarlet Jubilee’. In addition, petals of plants of the new Phalaenopsis have narrow white-colored edges whereas petals of plants of ‘Scarlet Jubilee’ do not have colored edges.

The accompanying photographs illustrate the overall appearance of the new Phalaenopsis plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Phalaenopsis plant.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the autumn 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.
