Lady Emma Strawberry Plant Compact Architecture High Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strawberry varieties lack consistent and high-yielding, conical-shaped fruit with strong remontant behavior and compact architecture, often exhibiting variability in fruit size and color, and are susceptible to environmental conditions.
Innovation Solution
The development of a new strawberry variety, 'Lady Emma', resulting from a cross between SA22 and SA11, which exhibits larger flowers and fruit, stronger remontant behavior, and a more compact architecture, while maintaining consistent conical fruit shape and high yields, with improved resistance to powdery mildew and crown rot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional strawberry varieties are used, then fruit yield is achieved, but fruit shape consistency and size uniformity deteriorate
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that control fruit shape and size consistency. The 'Lady Emma' variety was developed through selective breeding to optimize parameters including fruit shape uniformity (conical shape consistency), size uniformity across positions, and yield performance, resolving the contradiction between precision and productivity.
2Volume of moving object
If strawberry varieties with larger flowers and fruit are developed, then fruit size is improved, but plant architecture becomes less compact
Solution Approach 1:
The patent utilizes parameter changes by breeding 'Lady Emma' with optimized genetic parameters that simultaneously achieve larger fruit volume (20-30g average weight) and maintain compact plant architecture. The variety exhibits a balance between flower/fruit size parameters and plant structural parameters, resolving the contradiction through selective breeding for specific parameter combinations.
3Duration of action of moving object
If remontant behavior is strengthened in strawberry varieties, then fruit production duration is extended, but vegetative growth is reduced
Solution Approach 1:
The patent applies parameter changes by developing 'Lady Emma' with optimized remontant behavior parameters. The variety exhibits strong remontant characteristics (producing multiple crops per year) while maintaining adequate vegetative growth parameters, achieving a balance between fruit production duration and vegetative development through selective breeding.
4Productivity
If strawberry varieties are bred for high yield, then productivity is improved, but resistance to diseases deteriorates
Solution Approach 1:
The patent applies the composite materials principle by developing 'Lady Emma' as a composite genetic variety that integrates multiple desirable traits: high yield potential, powdery mildew resistance, and crown rot resistance. The variety combines resistance genes from different parent lines while maintaining productivity, creating a composite genotype that resolves the contradiction between yield and disease resistance.
