Sucherry2 Cherry Tree Hybridization for Early Ripening and Large Fruit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of cherry tree that ripens early, with large fruit size and specific characteristics such as dark red flesh and skin, which are not adequately met by existing cherry tree varieties.
Innovation Solution
The development of the 'Sucherry2' cherry tree variety, achieved through hybridization of 'Cherry-2' and 'LCCherry2', which exhibits early ripening, larger fruit size, and distinct characteristics like reniform fruit shape and reduced chilling requirements, while maintaining these traits through asexual propagation methods like dormant grafting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If early ripening is achieved through hybridization, then harvest time is reduced, but fruit size and chilling requirements may be compromised
Solution Approach 1:
The patent combines the early ripening genes from the pollen parent with the large fruit size genes from the seed parent through controlled hybridization. This merging of parental traits produces offspring that simultaneously exhibit both early harvest characteristics and large fruit size, resolving the contradiction between these two parameters.
Solution Approach 2:
The hybridization process changes the genetic parameters of the cherry tree to achieve a new combination of traits. By altering the genetic composition through cross-breeding, the resulting variety attains both reduced time to harvest and increased fruit size that would not be possible in either parent alone.
2Loss of time
If early blooming is achieved, then harvest starts earlier, but chilling requirement increases
Solution Approach 1:
The hybridization process changes the genetic parameters to achieve a new balance between bloom time and chilling requirement. The resulting variety has modified physiological parameters that allow early blooming while maintaining a moderate chilling requirement of 450 hours, which is higher than some ultra-early varieties but lower than traditional late-blooming types.
3Quantity of substance
If large fruit size is achieved, then market appeal improves, but productivity per tree may decrease
Solution Approach 1:
The patent applies local quality by ensuring that the large fruit size trait is expressed in the fruit itself, while the tree's overall productivity is maintained through proper vegetative propagation and tree management. The exceptional fruit size (up to 10g) is a localized characteristic of the fruit, while the tree can produce multiple fruits, balancing both parameters.
4Shape
If distinct fruit characteristics (dark red flesh and skin) are achieved, then market appeal improves, but genetic stability may be compromised
Solution Approach 1:
The patent uses vegetative propagation (grafting) to create exact genetic copies of the hybrid cherry tree. This copying process ensures that the distinctive dark red flesh and skin characteristics are perfectly replicated in all propagated plants, maintaining genetic stability and uniformity of fruit appearance across the entire population.
