Meiscouby Floribunda Rose Breeding for Fast Repeat Bloom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of floribunda rose plant that exhibits unique characteristics such as deeper flower color, higher petal count, larger flower diameter, and faster repeat bloom, while maintaining stability through asexual propagation, and being resistant to powdery mildew.
Innovation Solution
The development of the 'Meiscouby' floribunda rose plant, created by controlled breeding, which possesses purple-magenta blossoms, medium green matte foliage, and a bushy upright growth habit, and is distinguished by its earlier blooming and faster repeat bloom compared to its ancestors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If controlled breeding is performed to achieve deeper flower color, higher petal count, and larger flower diameter, then the ornamental value is improved, but the breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-selecting parent plants with specific desirable traits (deeper flower color, higher petal count, larger diameter) before performing the controlled cross-breeding. The female parent from the ('KORblue' x 'Delboip') cross and the male parent 'FRAntasia' were both carefully chosen to contribute specific characteristics, allowing the breeding process to move more efficiently toward the desired outcome without requiring multiple generations of selection.
2Stability of the object's composition
If asexual propagation is used to ensure homogeneous and stable characteristics, then the genetic stability is improved, but the propagation process complexity increases
Solution Approach 1:
The patent applies copying through asexual propagation methods where exact genetic copies of the selected rose plant are produced. Techniques such as budding create clones that are genetically identical to the parent plant, ensuring homogeneous and stable characteristics are transmitted from one generation to another without the variability introduced by sexual reproduction.
3Productivity
If the rose plant is bred for earlier blooming and faster repeat bloom, then the productivity is improved, but the plant's physiological stress increases
Solution Approach 1:
The patent applies periodic action by breeding the rose plant to exhibit repeat blooming characteristics, where the plant cycles through flowering periods rather than blooming once. The 'Meiscouby' variety was selected for its ability to bloom repeatedly with faster intervals between flowering cycles, allowing the plant to distribute its reproductive effort across multiple periods rather than concentrating it in a single blooming event.

AI summary
A new and distinct variety of floribunda rose plant, referred to by its cultivar name, ‘Meiscouby’, is described. The new variety forms in abundance on a substantially continuous basis, purple-magenta-colored blossoms. The growth habit is bushy and upright. Matte, medium green ornamental foliage is formed. Additionally, the new variety is particularly well suited for growing as ornamentation in the landscape.
