Campbell Jonathan Apple Tree Bold Fruit Striping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Jonathan apple tree varieties lack a bold and distinctive striping pattern on their fruit, with most having faint or no striping, which limits their visual appeal and market differentiation.
Innovation Solution
A new variety, 'Campbell Jonathan', is introduced as a limb mutation of 'Robison' (U.S. Plant Pat. 2,934), characterized by a bold pattern of alternating dark red and lighter red stripes on the fruit, providing a unique visual appeal and distinctiveness from other Jonathan cultivars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Jonathan apple tree varieties are used, then the tree structure and basic fruit characteristics are maintained, but the fruit lacks bold and distinctive striping pattern
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a specific limb mutation that exhibits enhanced striping characteristics. The mutation changes the visual parameter of the fruit surface from faint or no striping to bold alternating dark red and lighter red stripes, while maintaining the basic Jonathan apple tree structure and fruit type.
Solution Approach 2:
The patent segments the fruit surface into distinct alternating bands of dark red and lighter red stripes. This segmentation creates the bold striping pattern that distinguishes the new variety from other Jonathan cultivars, providing visual differentiation while maintaining the overall fruit form.
2Illumination intensity
If faint or no striping is present on fruit, then the fruit appearance is simpler, but visual appeal and market differentiation are limited
Solution Approach 1:
The patent utilizes color changes by developing a fruit surface with bold alternating dark red and lighter red stripes. This coloration pattern enhances visual appeal and distinguishes the new variety from other Jonathan cultivars that have faint or no striping, while the colors remain natural to the apple fruit.

AI summary
A new and distinct variety of Jonathan apple tree, ‘Campbell Jonathan’ originating as a limb mutation of the Malus domestica variety of ‘Robison’, (U.S. Plant Pat. 2,934). This new variety is unique from its parent and other Jonathan cultivars in that it has a very bold pattern of alternating dark red and bright red stripes on the skin of its fruit, unlike its parent which has very faint, thin stripes.
