Dianthus Cultivar G22090: Patterned Flowers With Pathogen Tolerance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Dianthus cultivars lack large, uniquely patterned flowers with extended blooming periods and field tolerance to common pathogens, which limits their horticultural appeal and durability.
Innovation Solution
The new Dianthus cultivar 'G22090' is developed through a breeding program, characterized by large flowers with a light pink base color, a red-violet eye, and a distinct star pattern, along with a spreading and dense ground-cover habit, healthy glaucous blue-green foliage, and strong reblooming capabilities, as well as field tolerance to common Dianthus pathogens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Dianthus cultivars are used, then they have simpler flower patterns and shorter blooming periods, but they lack large uniquely patterned flowers with extended blooming periods and field tolerance to common pathogens
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific genetic traits that confer pathogen tolerance while maintaining or enhancing flower size and pattern complexity. The breeding program modifies genetic parameters to achieve simultaneous improvement in disease resistance and aesthetic characteristics.
Solution Approach 2:
The new cultivar represents a composite genetic material resulting from controlled cross-pollination between parent plants with complementary traits. One parent contributes pathogen tolerance while the other contributes large flower size and complex patterns, creating a composite genotype that expresses both sets of desirable characteristics.
2Shape
If breeders select for larger flowers with unique patterns, then floral aesthetics improve, but disease resistance may be compromised
Solution Approach 1:
The breeding program applies local quality by selecting for specific localized traits in different parts of the plant - large flowers with complex patterns in the floral portion while maintaining pathogen tolerance in the systemic plant defenses. This allows different regions or functions of the plant to excel at different characteristics.
Solution Approach 2:
The patent merges previously separate breeding objectives by combining selection for large uniquely patterned flowers with selection for field tolerance to common pathogens in a single integrated breeding program, achieving a cultivar that expresses both aesthetic and functional excellence simultaneously.
3Duration of action of moving object
If extended blooming periods are selected for, then horticultural appeal increases, but plant vigor may be reduced
Solution Approach 1:
The breeding program applies dynamics by selecting for plants that dynamically extend their blooming period while maintaining the physiological vigor needed to support prolonged flowering. The cultivar exhibits dynamic adaptation in resource allocation to sustain both extended bloom duration and overall plant strength.

AI summary
A new and distinct cultivar of Dianthus plant named ‘G22090’ is disclosed, characterized by large flowers with a base color of light pink with a large red-violet eye, and a very distinct star pattern in the same dark red-violet color radiating from the central eye down the petal to the petal tip. Healthy glaucous blue-green foliage exhibits good field tolerance to common Dianthus pathogens. The new variety is a Dianthus, normally used for outdoor ornamental purposes.
