Foreign priority is not claimed to this European Community Plant Breeder's Rights application.

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of x Doritaenopsis plant, botanically known as x Doritaenopsis (Doritis x Phalaenopsis), commonly referred to as Doritaenopsis and hereinafter referred to by the name ‘Ladies Day’.

The new Doritaenopsis 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 Doritaenopsis plants with good leaf shape and large flowers with unique and attractive patterns and coloration.

The new Doritaenopsis plant originated from a cross-pollination in June, 2011 in Nantou, Taiwan of x Doritaenopsis ‘Modern Valentine’, not patented, as the female, or seed, parent with x Doritaenopsis ‘Modern Rose’, not patented, as the male, or pollen, parent. The new Doritaenopsis 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 March, 2017.

Asexual reproduction of the new Doritaenopsis plant by in vitro meristem propagation in a controlled environment in Assendelft, The Netherlands since March, 2018 has shown that the unique features of this new Doritaenopsis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Doritaenopsis 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 ‘Ladies Day’. These characteristics in combination distinguish ‘Ladies Day’ as a new and distinct Doritaenopsis plant:

• • 1. Upright plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Strong leaves.
  • 4. Strong flowering stems.
  • 5. Freely flowering habit with typically two inflorescences per plant, each inflorescence with numerous flowers.
  • 6. Large reddish purple-colored flowers with light purple-colored centers.
  • 7. Good postproduction longevity.

Plants of the new Doritaenopsis can be compared to plants of the female parent, ‘Modern Valentine’. Plants of the new Doritaenopsis differ primarily from plants of ‘Modern Valentine’ in flower color as plants of the new Doritaenopsis have reddish purple-colored flowers with light purple-colored centers without distinct stripes or venation whereas plants of ‘Modern Valentine’ have white-colored flowers that are blushed with violet with dense and distinct stripes and venation.

Plants of the new Doritaenopsis can be compared to plants of the male parent, ‘Modern Rose’. Plants of the new Doritaenopsis differ primarily from plants of ‘Modern Rose’ in flower form as flower petals of plants of the new Doritaenopsis are free to touching whereas flower petals of plants of ‘Modern Rose’ are completely free. In addition, cirrose tips of the labella (also referred to as “whiskers”) of plants of the new Doritaenopsis are white in color whereas cirrose tips of the labella of plants of ‘Modern Rose’ are purple red in color.

Plants of the new Doritaenopsis can be compared to plants of x Doritaenopsis ‘Lady Fantasy’, disclosed in a Provisional U.S. Patent application Ser. No. 62/705,005 and in U.S. Plant patent application Ser. No. 17/340,015, filed concurrently. Plants of the new Doritaenopsis differ primarily from plants of ‘Lady Fantasy’ in growth habit as plants of the new Doritaenopsis are not as vigorous as plants of ‘Lady Fantasy’. In addition, plants of the new Doritaenopsis have smaller flowers than plants of ‘Lady Fantasy’.

Plants of the new Doritaenopsis can also be compared to plants of Phalaenopsis hybrida ‘Purple Dust’, disclosed in U.S. Plant Pat. No. 29,177. In side-by-side comparisons, plants of the new Doritaenopsis differ primarily from plants of ‘Purple Dust’ in flower color as plants of the new Doritaenopsis have reddish purple-colored flowers with light purple-colored centers whereas plants of ‘Purple Dust’ have purple/violet-colored flowers with a white-colored haze in the center. In addition, flowers of plants of the new Doritaenopsis are arranged on racemes whereas flowers of plants of ‘Purple Dust’ are arranged on panicles.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the winter in 10.5-cm containers in a glass-covered greenhouse in Heemskerk, The Netherlands and under cultural practices typically used in commercial Doritaenopsis 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 18 months of production, light levels ranged from a minimum of 5,000 lux to a maximum of 10,000 lux.
