Description

Botanical designation: Phalaenopsis hybrida.


Cultivar denomination: ‘MI01248’.


STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR/APPLICANT

An European Community Plant Breeder's Rights application for the instant plant was filed by the Assignee of the instant application, Microflor N.V. of Lochristi, Belgium on Oct. 24, 2018, application number 2018/2685. Foreign priority is not claimed to this application.


The Inventor/Applicant and 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/Applicant and/or the Assignee. Inventor/Applicant and Assignee claim a prior art exemption 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 Phalaenopsis plant, botanically known as Phalaenopsis hybrida, and hereinafter referred to by the name ‘MI01248’.


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 freely flowering Phalaenopsis plants with good leaf shape and unique and attractive flower coloration.


The new Phalaenopsis plant originated from a cross-pollination by the Inventor in 2011 in Lochristi, Belgium of a proprietary selection of Phalaenopsis hybrida identified as code number PH00961, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number PH01170, 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 December, 2014.


Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Lochristi, Belgium since February, 2016 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 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 ‘MI01248’. These characteristics in combination distinguish ‘MI01248’ as a new and distinct Phalaenopsis plant:

    • 1. Upright plant habit.
    • 2. Vigorous growth habit.
    • 3. Strong flowering stems.
    • 4. Strong and relatively small leaves.
    • 5. Freely flowering habit with typically two racemes per plant, each inflorescence with numerous flowers.
    • 6. Large white-colored flowers.


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. Plants of the new Phalaenopsis have larger flowers than plants of the female parent selection.
    • 2. Plants of the new Phalaenopsis are more freely flowering than 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. Plants of the new Phalaenopsis are shorter than plants of the male parent selection.
    • 2. Plants of the new Phalaenopsis have shorter leaves than plants of the male parent selection.
    • 3 Plants of the new Phalaenopsis have smaller flowers plants of the male parent selection.


Plants of the new Phalaenopsis can be compared to plants of Phalaenopsis hybrida ‘MI00901’, disclosed in U.S. Plant Pat. No. 30,686. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘MI00901’ in the following characteristics:

    • 1. Plants of the new Phalaenopsis have shorter inflorescences than plants of ‘MI00901’.
    • 2. Plants of the new Phalaenopsis have smaller flowers than plants of ‘MI00901’.
