Description

[0001] Botanical designation: Phalaenopsis hybrida.

[0002] Cultivar denomination: ‘MI03271’.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 of the instant application, Microflor N.V. of Lochristi, Belgium on Apr. 18, 2024, application number 2024 / 0881. Foreign priority is not claimed to this European Community Plant Breeder's Rights 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 ‘MI03271’.

[0005] The new Phalaenopsis plant is a product of a planned breeding program conducted by the Inventor in Lochristi, Belgium. 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 February 2018 in Lochristi, Belgium of a proprietary selection of Phalaenopsis hybrida identified as code number PH02905 E, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number PH03295, 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 Lochristi, Belgium in November 2020.

[0007] Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Lochristi, Belgium since November 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 ‘MI03271’. These characteristics in combination distinguish ‘MI03271’ as a new and distinct Phalaenopsis plant:

[0010] 1. Upright plant habit.

[0011] 2. Leaves that are semi-erect to horizontal in orientation.

[0012] 3. Strong flowering stems.

[0013] 4. Freely flowering habit with typically about two or three inflorescences per plant, each inflorescence with numerous flowers.

[0014] 5. Bright yellow-colored flowers.

[0015] 6. Excellent postproduction longevity.

[0016] 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:

[0017] 1. Plants of the new Phalaenopsis flower about two weeks earlier than plants of the female parent selection.

[0018] 2. Plants of the new Phalaenopsis are more freely flowering than plants of the female parent selection.

[0019] 3. Plants of the new Phalaenopsis have larger flowers than 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. Leaves of plants of the new Phalaenopsis are shorter than leaves of plants of the male parent selection.

[0022] 2. Plants of the new Phalaenopsis are more freely flowering than plants of the male parent selection.

[0023] 3. Plants of the new Phalaenopsis have smaller flowers than plants of the male parent selection.

[0024] Plants of the new Phalaenopsis can be compared to plants of Phalaenopsis hybrida ‘YH0207’, also known by the trade name Golden Coin, not patented. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘YH0207’ in the following characteristics:

[0025] 1. Leaves of plants of the new Phalaenopsis are not as sensitive to burning during the cooling period as leaves of plants of ‘YH0207’.

[0026] 2. Plants of the new Phalaenopsis are more freely flowering than plants of ‘YH0207’.

[0027] 3. Plants of the new Phalaenopsis have larger flowers than plants of ‘YH0207’.BRIEF DESCRIPTION OF THE PHOTOGRAPHS
