SPC411 Cherry Cultivar Resolving Fruit Splitting and Firmness Trade-off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cherry tree cultivars face challenges in fruit appearance, firmness, splitting resistance, storage potential, and disease resistance, with limited self-fertility and inconsistent harvest timing.
Innovation Solution
The development of the 'SPC411' sweet cherry tree cultivar, which is bred for improved fruit size, firmness, low splitting, self-fertile flowers, and enhanced storage potential, achieved through asexual propagation by budding onto Mazzard rootstock, combining desirable traits such as late harvest timing and disease resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing cherry tree cultivars are grown for fruit production, then fruit yield is achieved, but fruit firmness and splitting resistance are insufficient
Solution Approach 1:
The patent applies parameter changes by developing a new cultivar with modified genetic parameters that result in altered fruit physical properties. The 'SPC411' cultivar exhibits changed parameters including fruit firmness, skin thickness, and flesh texture that collectively improve splitting resistance while maintaining commercial viability.
2Manufacturing precision
If cherry cultivars are bred for improved fruit appearance and taste, then fruit quality is enhanced, but disease resistance and tree quality may be compromised
Solution Approach 1:
The patent merges multiple desirable traits into a single cultivar through controlled breeding. The 'SPC411' cultivar combines improved fruit appearance (dark red color, glossy skin), enhanced taste (balanced sweetness and acidity), and maintained disease resistance, integrating these previously separate advantages into one unified variety.
3Loss of time
If cherry trees are selected for self-fertility, then harvest timing consistency is improved, but fruit size and firmness may be reduced
Solution Approach 1:
The patent utilizes parameter changes through selective breeding to optimize the relationship between flowering characteristics and fruit development. The 'SPC411' cultivar exhibits changed parameters in both reproductive biology (self-fertility, consistent blooming period) and fruit morphology (large size, firm texture), breaking the traditional trade-off between these characteristics.
4Volume of moving object
If cherry cultivars are developed for large fruit size, then marketability is improved, but natural splitting increases
Solution Approach 1:
The patent applies composite material principles by developing fruit with a composite structure that combines different tissue properties. The 'SPC411' cultivar exhibits a composite fruit structure with reinforced skin-flesh interface, thicker epidermis, and modified flesh composition that together create a more resilient fruit capable of withstanding expansion forces during growth while resisting environmental cracking.
