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 ‘MI01181’.
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 relatively small flowers with 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 PH01616, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number PH01477, 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 September, 2014.
Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Lochristi, Belgium since May, 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 ‘MI01181’. These characteristics in combination distinguish ‘MI01181’ 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 inflorescences per plant, each inflorescence with numerous flowers.
- 6. Small white-colored flowers with large red purple-colored lateral spots on the lateral petals.
- 7. Good postproduction longevity and resistance to bud drop during transport.
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. Inflorescences of plants of the new Phalaenopsis are shorter than inflorescences of plants of the female parent selection.
- 2. Plants of the new Phalaenopsis have smaller flowers than plants of the female parent selection.
- 3. The flower labella of plants of the new Phalaenopsis are yellow and white in color whereas the flower labella of plants of the female parent selection are pink in color.
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 have white-colored flowers with large red purple-colored lateral spots on the lateral petals whereas plants of the male parent selection are white-colored flowers without spots.
- 2. The flower labella of plants of the new Phalaenopsis are yellow and white in color whereas the flower labella of plants of the male parent selection are orange red in color.
Plants of the new Phalaenopsis can be compared to plants of Phalaenopsis hybrida ‘MI00819’, not patented. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘MI00819’ in the following characteristics:
- 1. Plants of the new Phalaenopsis have shorter inflorescences than plants of ‘MI00819’.
- 2. Plants of the new Phalaenopsis have smaller flowers than plants of ‘MI00819’.
Plants of the new Phalaenopsis can also be compared to plants of Phalaenopsis hybrida ‘Anastasia 7’, not patented. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘Anastasia 7’ in the following characteristics:
- 1. Plants of the new Phalaenopsis are taller than plants of ‘Anastasia 7’.
- 2. Plants of the new Phalaenopsis have white-colored flowers with large red purple-colored lateral spots on the lateral petals whereas plants of ‘Anatasia 7’ have white-colored flowers with or without spots.
