RKD Apple Tree Early Maturing Fruit Mutation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new apple tree variety that exhibits early maturing and early full-coloring fruit characteristics, as existing Gala-type varieties like 'Tenroy' do not meet these criteria effectively.
Innovation Solution
The 'RKD' apple tree variety, originating from a spontaneous two-limb mutation of 'Tenroy', is distinguished by its early maturing and early full-coloring fruit, with specific botanical descriptions and comparisons to other Gala-type varieties highlighting its unique traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If existing Gala-type varieties like 'Tenroy' are used, then fruit production is achieved, but early maturing and early full-coloring characteristics are not met
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a spontaneous mutation variant ('RKD') that exhibits altered developmental parameters compared to the parent 'Tenroy' variety. Specifically, the mutation results in accelerated maturation rate and earlier full-coloring timing while maintaining fruit quality standards, thereby resolving the contradiction between early harvest timing and consistent fruit quality
2Speed
If early maturing varieties are selected, then harvest timing is improved, but fruit coloring development may be compromised
Solution Approach 1:
The patent applies local quality by observing that the spontaneous mutation in 'RKD' creates localized changes in specific fruit characteristics (accelerated maturation and coloring) while preserving other quality attributes. The mutation affects particular developmental pathways independently, allowing early maturation without compromising overall fruit coloration quality
