Miniature Rose Plant Compact Growth and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a miniature rose plant with attractive, medium-red colored blossoms and a compact growth habit that offers good ornamental value for parks, gardens, and residential settings, while also providing resistance to diseases like Botrytis and powdery mildew.
Innovation Solution
The development of the Rosa hybrida 'KORpot089' variety, created through artificial pollination of 'KORsinski' and 'KORpolare' parents, which exhibits medium-red blossoms, compact growth, and vigorous vegetation, and demonstrates stable and homogeneous characteristics through asexual propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the rose plant is bred for larger flowers, then flower size increases, but the growth habit becomes less compact
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific trait combinations - maintaining medium-sized flowers (not large) while achieving compact growth habit. This resolves the contradiction by changing the parameter values to an optimal middle ground that satisfies both ornamental value and space-efficient growth requirements for container cultivation.
2Quantity of substance
If the rose plant is bred for higher petal count, then flower complexity increases, but the overall flower size and plant compactness are compromised
Solution Approach 1:
The patent resolves this contradiction by changing multiple parameters simultaneously - achieving medium petal count (not excessive) while maintaining medium flower size and compact growth. This balanced parameter optimization allows the plant to meet ornamental requirements without sacrificing compactness or flower size.
3Productivity
If the rose plant exhibits vigorous vegetation, then plant productivity increases, but control over growth form becomes more difficult
Solution Approach 1:
The patent resolves this contradiction by changing the growth habit parameter to compact while maintaining vigorous vegetation. This parameter combination ensures that the plant produces abundant foliage and flowers (high productivity) while the compact growth form maintains control over plant shape and size, making it suitable for container cultivation and landscape applications.
4Reliability
If the rose plant is bred for disease resistance, then reliability improves, but ornamental characteristics may be compromised
Solution Approach 1:
The patent resolves this contradiction by changing multiple parameters to achieve a balanced phenotype - the plant exhibits good disease resistance (improving reliability) while simultaneously maintaining medium-red colored blossoms, compact growth habit, and vigorous vegetation (preserving ornamental value). This multi-parameter optimization ensures both health and aesthetic requirements are met.
