Description

Genus and species: Phalaenopsis hybrid.

Variety denomination: ‘PHA217131’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct cultivar of Phalaenopsis plant, botanically known as Phalaenopsis hybrid of the Orchidaceae family, commonly referred to as moth orchid, and hereinafter referred to by the variety name ‘PHA217131’.

The new Phalaenopsis plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, the Netherlands. The objective of this breeding program was to create a new Phalaenopsis plant with attractive, dark reddish-purple flowers with small light reddish-purple centers and dark red lips, suitable for potted plant production.

The new Phalaenopsis plant ‘PHA217131’ is a result of cross-pollination made by the inventor in January 2013 in Bleiswijk, the Netherlands, of the proprietary female, or seed parent, Phalaenopsis hybrid ‘17956-06’ (unpatented) with the proprietary male, or pollen parent, Phalaenopsis hybrid ‘01-3389’ (unpatented).

The new Phalaenopsis was selected by the inventor as a single plant within the progeny of the stated cross-pollination in a controlled greenhouse in Bleiswijk, the Netherlands, in November 2015. Asexual reproduction of the new Phalaenopsis plant by meristem tissue culture since 2017 in Bleiswijk, the Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations.

Community Plant Variety Rights for this variety have been applied for in the European Union on Jan. 29, 2021 (Application no. 2021/0306), by Applicant who obtained the subject matter disclosed directly from the inventor. ‘PHA217131’ has not been made publicly available or sold anywhere in the world prior to the effective filing date of this application with the exception of sales or disclosures made one year or less before the effective filing date of this claimed invention by Applicant who obtained ‘PHA217131’ directly from the inventor.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Bleiswijk, the Netherlands, and can be used to distinguish ‘PHA217131’ as a new and distinct variety of Phalaenopsis plant:

• • 1) Dark reddish-purple flowers with small light reddish-purple centers and dark red lips;
  • 2) Flower shape in lateral view is concave; and
  • 3) Apical lobe of the lip has a small bump and ridge.

DESCRIPTION OF THE PHOTOGRAPHS

This new Phalaenopsis plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken in a greenhouse in Bleiswijk, the Netherlands, from 50-week-old plants in November 2021. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 1 shows the overall plant habit, including blooms, buds, and foliage of ‘PHA217131’.

FIG. 2 shows a close-up of a flower of ‘PHA217131’.

FIG. 3 shows an overhead view of the leaves of ‘PHA217131’.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘PHA217131’. Plants of the new Phalaenopsis have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, and day length, 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, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined under 4000-6000 lux natural light in a greenhouse in Bleiswijk, the Netherlands. Observations and measurements were made in November 2021 on flowering plants which were planted in 12-centimeter (diameter) pots. After in vitro propagation, the plants were grown in nursery trays for 20-24 weeks, followed by transplantation to 12-centimeter pots and grown in a greenhouse between 27° C. to 29° C. for 30 weeks, continued by a cooling period of 8 weeks between 18° C. to 20° C. and 12 weeks in a greenhouse of 21° C. Flowering occurs after 50 weeks in 12-centimeter pots.

COMPARISON WITH PARENTAL LINES AND MOST SIMILAR VARIETIES

‘PHA217131’ differs from the female parent plant ‘17956-06’ (unpatented) in that ‘PHA217131’ has elliptic apical lobes and leaves with no anthocyanin coloration on the upper surface, whereas ‘17956-06’ has rhombic apical lobes and leaves with very weak to weak anthocyanin coloration on the upper surface. Additionally, ‘PHA217131’ has smaller flowers than ‘17956-06’.

‘PHA217131’ differs from the male parent plant ‘01-3389’ (unpatented) in that ‘PHA217131’ has pedicels with a main color of yellow-green and elliptic apical lobes, whereas ‘01-3389’ has pedicels with a main color of light reddish-purple and ovate apical lobes.

‘PHA217131’ is most similar to the commercial Phalaenopsis plants named ‘PHALFEMYM’ (U.S. Plant Pat. No. 29,783) and ‘PHALBIRWIN’ (U.S. Plant Pat. No. 33,727). ‘PHA217131’ differs from the commercial variety ‘PHALFEMYM’ in that ‘PHA217131’ has elliptic apical lobes, dark red-purple whiskers, and leaves with a semi-erect attitude, whereas ‘PHALFEMYM’ has ovate apical lobes, red-purple whiskers, and leaves with a horizontal to semi-drooping attitude.

‘PHA217131’ differs from the commercial variety ‘PHALBIRWIN’ in that ‘PHA217131’ has elliptic apical lobes, dark red-purple whiskers, and flowers that are concave in lateral view, whereas ‘PHALBIRWIN’ has circular apical lobes, dark purplish-red whiskers with small white tips, and flowers that are flat in lateral view.
