Phalaenopsis plant named ‘MI02648’

Abstract

A new and distinct cultivar of Phalaenopsis plant named ‘MI02648’, characterized by its upright plant habit; vigorous growth habit and rapid growth rate; strong and flexible flowering stems; compact and semi-erect leaves; freely flowering habit with typically two inflorescences per plant, each inflorescence with numerous flowers; bright yellow-colored flowers with reddish orange-colored stripes that resist fading; and good postproduction longevity.

Description

Botanical designation: Phalaenopsis hybrida.

Cultivar denomination: ‘MI02648’.

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 ‘MI02648’.

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 large flowers with unique and attractive flower coloration.

The new Phalaenopsis plant originated from a cross-pollination by the Inventor in September, 2016 in Lochristi, Belgium of a proprietary selection of Phalaenopsis hybrida identified as code number PHM00322, not patented, as the female, or seed, parent with a proprietary selection of Phalaenopsis hybrida identified as code number PH02885, 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 May, 2019.

Asexual reproduction of the new Phalaenopsis plant by in vitro meristem propagation in a controlled environment in Lochristi, Belgium since August, 2020 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 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.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘M102648’. These characteristics in combination distinguish ‘M102648’ as a new and distinct Phalaenopsis plant:

• • 1. Upright plant habit.
  • 2. Vigorous growth habit and rapid growth rate.
  • 3. Strong and flexible flowering stems.
  • 4. Compact and semi-erect leaves.
  • 5. Freely flowering habit with typically two inflorescences per plant, each inflorescence with numerous flowers.
  • 6. Bright yellow-colored flowers with reddish orange-colored stripes that resist fading.
  • 7. Good postproduction longevity.

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 flower two weeks earlier than plants of the female parent selection.
  • 2. Plants of the new Phalaenopsis produce twice as many flowers per inflorescence as plants of the female parent selection.
  • 3. Flowers of plants of the new Phalaenopsis are bright yellow in color with reddish orange-colored stripes whereas flowers of plants of the female parent selection are yellow in color with greyed orange-colored spots.

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. Flower buds of plants of the new Phalaenopsis are solid yellowish green in color whereas flower buds of plants of the male parent selection are yellowish green in color with violet-colored stripes.
  • 2. Central lobe of the labellum of plants of the new Phalaenopsis are trullate in shape whereas central lobe of the labellum of plants of the male parent selection are triangular in shape.
  • 3. Flowers of plants of the new Phalaenopsis are bright yellow in color with reddish orange-colored stripes whereas flowers of plants of the male parent selection are white in color with violet-colored stripes.

Plants of the new Phalaenopsis can be compared to plants of Phalaenopsis hybrida ‘Fuller's Secret’, not patented. In side-by-side comparisons, plants of the new Phalaenopsis differ primarily from plants of ‘Fuller's Secret’ in the following characteristics:

• • 1. Plants of the new Phalaenopsis have slightly smaller flowers than plants of ‘Fuller's Secret’.
  • 2. Flowers of plants of the new Phalaenopsis are bright yellow in color with reddish orange-colored stripes whereas flowers of plants of ‘Fuller's Sunset’ are yellow in color without stripes.
