Early-Maturing Mandarin Variety With Thin Rind and Small Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mandarin varieties lack distinct characteristics such as fruit color, flesh color, maturity, and core characteristics, which are not adequately addressed by existing cultivars like 'Mikanken4' and 'HAREHIME'.
Innovation Solution
Development of a new mandarin variety 'Mikanken14' through asexual reproduction, characterized by vivid orange fruit surface, strong orange flesh, very early maturity, thin rind, sparse core filling, and small core diameter, differentiated from its parents and comparative varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If existing mandarin varieties are cultivated, then fruit production is achieved, but distinct characteristics in fruit color, flesh color, maturity timing, and core characteristics are insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific quantitative traits: fruit surface color (orange to vivid orange), flesh color (orange to strong orange), maturity timing (late to very early), rind thickness (thick to very thin), core filling (sparse to absent), and core diameter (medium to very small). These parameter modifications create the distinct characteristics of the new variety while maintaining fruit production capability.
2Stability of the object's composition
If fruit maturity is delayed, then fruit development is complete, but consumer appeal and market timing are reduced
Solution Approach 1:
The patent employs preliminary action by accelerating the fruit development process through selective breeding, enabling the fruit to reach full maturity with complete development much earlier than traditional varieties. The new variety achieves very early maturity while maintaining complete fruit development, allowing consumers to enjoy fully developed fruit earlier in the season.
3Ease of operation
If rind thickness is reduced, then consumer appeal and juice accessibility are improved, but fruit protection and structural integrity are compromised
Solution Approach 1:
The patent applies parameter changes by modifying the rind thickness from thick to very thin, which improves juice accessibility and consumer appeal. This parameter modification is achieved through selective breeding while maintaining adequate structural integrity through complementary traits in the overall fruit structure.
4Stability of the object's composition
If core filling is increased, then fruit structure is more complete, but edible flesh proportion and consumer appeal are reduced
Solution Approach 1:
The patent applies parameter changes by modifying core filling from sparse to absent and core diameter from medium to very small. These changes increase the proportion of edible flesh while maintaining fruit structure completeness through the overall integrity of the fruit segments and rind, thereby improving consumer appeal.
