Description

[0001] Botanical designation: Phalaenopsis hybrida.

[0002] Cultivar denomination: ‘HELIX BRIDGE’.CROSS-REFERENCED TO CLOSELY-RELATED APPLICATIONS

[0003] A European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant / Assignee, Floricultura B.V. of Heemskerk, The Netherlands on Oct. 9, 2024, application number 2024 / 2358. Foreign priority is not claimed to this application.BACKGROUND OF THE INVENTION

[0004] 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 ‘Helix Bridge’.

[0005] 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.

[0006] The new Phalaenopsis plant originated from a cross-pollination in August, 2014 in De Lier, The Netherlands of a proprietary selection of Phalaenopsis hybrida identified as code number 362644, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number B3024, 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 November, 2020.

[0007] Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Assendelft, The Netherlands since December, 2021 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

[0008] 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.

[0009] The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Helix Bridge’. These characteristics in combination distinguish ‘Helix Bridge’ as a new and distinct Phalaenopsis plant:

[0010] 1. Upright plant habit.

[0011] 2. Moderately vigorous growth habit.

[0012] 3. Strong flowering stems.

[0013] 4. Healthy and sturdy leaves.

[0014] 5. Freely flowering habit with typically two inflorescences developing per plant, each inflorescence with numerous flowers.

[0015] 6. Flower petals and sepals that are reddish purple in color.

[0016] 7. Good postproduction longevity.

[0017] 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:

[0018] 1. At the base of the flower petals of plants of the new Phalaenopsis there are fine dots whereas at the base of the flower petals of plants of the female parent selection there are no dots.

[0019] 2. Cirrhose apices of the labella of plants of the new Phalaenopsis are lighter in color than cirrhose apices of the labella of plants of the female parent selection.

[0020] 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:

[0021] 1. Flower petals of plants of the new Phalaenopsis are not netted whereas flower petals of plants of the male parent selection are netted.

[0022] 2. Cirrhose apices of the labella of plants of the new Phalaenopsis are lighter in color than cirrhose apices of the labella of plants of the male parent selection.

[0023] Plants of the new Phalaenopsis can be compared to plants of x Phalaenopsis hybrida ‘Coronado’, disclosed in U.S. Plant patent application Ser. No. 19 / 243,678. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘Coronado’ in the following characteristics:

[0024] 1. Flowers of plants of the new Phalaenopsis are broader than flowers of plants of ‘Coronado’.

[0025] 2. Flower petals of plants of the new Phalaenopsis are not netted whereas flower petals of plants of ‘Coronado’ are netted.

[0026] 3. Flower columns of plants of the new Phalaenopsis are mostly reddish purple in color whereas flower columns of plants of ‘Coronado’ are mostly dark yellow in color.BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0003] A European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant / Assignee, Floricultura B.V. of Heemskerk, The Netherlands on Oct. 9, 2024, application number 2024 / 2358. Foreign priority is not claimed to this application.BACKGROUND OF THE INVENTION

[0004] 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 ‘Helix Bridge’.

[0005] 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.

[0006] The new Phalaenopsis plant originated from a cross-pollination in August, 2014 in De Lier, The Netherlands of a proprietary selection of Phalaenopsis hybrida identified as code number 362644, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number B3024, 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 November, 2020.

[0007] Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Assendelft, The Netherlands since December, 2021 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

[0008] 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.

[0009] The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Helix Bridge’. These characteristics in combination distinguish ‘Helix Bridge’ as a new and distinct Phalaenopsis plant:

[0010] 1. Upright plant habit.

[0011] 2. Moderately vigorous growth habit.

[0012] 3. Strong flowering stems.

[0013] 4. Healthy and sturdy leaves.

[0014] 5. Freely flowering habit with typically two inflorescences developing per plant, each inflorescence with numerous flowers.

[0015] 6. Flower petals and sepals that are reddish purple in color.

[0016] 7. Good postproduction longevity.

[0017] 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:

[0018] 1. At the base of the flower petals of plants of the new Phalaenopsis there are fine dots whereas at the base of the flower petals of plants of the female parent selection there are no dots.

[0019] 2. Cirrhose apices of the labella of plants of the new Phalaenopsis are lighter in color than cirrhose apices of the labella of plants of the female parent selection.

[0020] 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:

[0021] 1. Flower petals of plants of the new Phalaenopsis are not netted whereas flower petals of plants of the male parent selection are netted.

[0022] 2. Cirrhose apices of the labella of plants of the new Phalaenopsis are lighter in color than cirrhose apices of the labella of plants of the male parent selection.

[0023] Plants of the new Phalaenopsis can be compared to plants of x Phalaenopsis hybrida ‘Coronado’, disclosed in U.S. Plant patent application Ser. No. 19 / 243,678. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘Coronado’ in the following characteristics:

[0024] 1. Flowers of plants of the new Phalaenopsis are broader than flowers of plants of ‘Coronado’.

[0025] 2. Flower petals of plants of the new Phalaenopsis are not netted whereas flower petals of plants of ‘Coronado’ are netted.

[0026] 3. Flower columns of plants of the new Phalaenopsis are mostly reddish purple in color whereas flower columns of plants of ‘Coronado’ are mostly dark yellow in color.BRIEF DESCRIPTION OF THE PHOTOGRAPHS

Embodiment Construction

[0030]The aforementioned photographs and following observations and measurements describe plants grown during the winter in 11-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 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 klux to a maximum of 10 klux. 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.[0031]Botanical classification: Phalaenopsis hybrida ‘Helix Bridge’.[0032]Parentage:[0...
