A U.S. Provisional Patent application for the instant plant was filed by the Inventor of the instant application, Mr. Martinus Nicolaas Gerardus van Swieten on Aug. 2, 2024. Domestic priority is hereby claimed to this U.S. Provisional Patent application Ser. No. 63/679,023.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Phalaenopsis plant, botanically known as Phalaenopsis hybrida, commonly referred to as a Phalaenopsis or Moth Orchid and hereinafter referred to by the name ‘PHA760527’.

The new Phalaenopsis plant is a product of a planned breeding program conducted by the Inventor in Bleiswijk, The Netherlands. The objective of the breeding program is to develop new medium-sized and freely flowering Phalaenopsis plants with flowers with unique and attractive patterns and coloration.

The new Phalaenopsis plant originated from a cross-pollination in August, 2017 in Bleiswijk, The Netherlands of a proprietary selection of Phalaenopsis hybrida identified as code number 13-056991-0002, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number 13-057810-0003, 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 Bleiswijk, The Netherlands in May, 2020.

Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Bleiswijk, The Netherlands since May, 2020 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 ‘PHA760527’. These characteristics in combination distinguish ‘PHA760527’ as a new and distinct Phalaenopsis plant:

- 1. Upright plant habit.
- 2. Relatively moderately vigorous to vigorous growth habit and moderate growth rate.
- 3. Strong flowering stems.
- 4. Healthy and sturdy leaves.
- 5. Freely flowering habit with typically three inflorescences developing per plant, each inflorescence with numerous flowers.
- 6. Pale yellow-colored flowers with darker yellow and red purple-colored labella.
- 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 the following characteristics:

- 1. Leaf aspect of plants of the new Phalaenopsis is semi-erect to horizontal whereas leaf aspect of plants of the female parent selection is horizontal to semi-drooping.
- 2. Flower labella of plants of the new Phalaenopsis are not as broad as flower labella of plants of the female parent selection.
- 3. Cirrhose tips of plants of the new Phalaenopsis are longer than cirrhose tips of plants of the female parent selection.

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 pale yellow in color whereas flower petals of plants of the male parent selection are light yellow green in color.
- 2. The labella lateral lobes of plants of the new Phalaenopsis are more inwardly curved than the labella lateral lobes of plants of the male parent selection.
- 3. Cirrhose tips of plants of the new Phalaenopsis are yellowish green in color whereas cirrhose tips of plants of the male parent selection are reddish orange in color

Plants of the new Phalaenopsis can be compared to plants of Phalaenopsis hybrida ‘PHA402006’, not patented. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘PHA402006’ in the following characteristics:

- 1. Flowers of plants of the new Phalaenopsis are not as broad as flowers of plants of ‘PHA402006’.
- 2. The labella lateral lobes of plants of the new Phalaenopsis are more inwardly curved than the labella lateral lobes of plants of ‘PHA402006’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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.

The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘PHA760527’ grown in a container.

The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical flower of ‘PHA760527’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the early autumn in 12-cm containers in a glass-covered greenhouse in Bleiswijk, The Netherlands and grown under cultural practices typically used in commercial Phalaenopsis production. Plants were 18 months old when the photographs and description were taken. During the first 14 months of production of the plants, day and night temperatures averaged 28.5° C., and during the last four months of production of the plants, day and night temperatures averaged 20° C. Throughout the production of the plants, light levels ranged from 100 μmol to 180 μmol. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
