Royal Sonia Cherry Tree Self-Compatibility and Maturity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cherry tree varieties, such as 'Royal Lynn' and 'Royal Hazel', face challenges in self-compatibility and fruit maturity timing, which affect productivity and handling qualities.
Innovation Solution
A new cherry tree variety, 'Royal Sonia', originated from 'Royal Hazel' and budded onto 'Mahaleb' Rootstock, exhibits self-compatibility, later fruit maturity, and improved fruit quality, with characteristics like vigorous growth, attractive red skin, and good handling and shipping qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cherry tree varieties like 'Royal Lynn' and 'Royal Hazel' are used, then fruit production is achieved, but self-compatibility is poor and fruit maturity timing is suboptimal
Solution Approach 1:
The patent applies parameter changes by selecting and breeding cherry trees with modified genetic parameters that confer self-compatibility. The 'Royal Sonia' variety was developed through controlled breeding to change the self-compatibility parameter from poor (in parent varieties) to good, enabling reliable self-pollination and consistent fruit production without requiring cross-pollination partners.
2Loss of time
If early maturing cherry varieties are used, then fruit is available earlier, but handling and shipping qualities are compromised
Solution Approach 1:
The patent changes the maturity timing parameter by developing 'Royal Sonia' to mature approximately 7 days later than the parent 'Royal Hazel' variety. This parameter adjustment allows the fruit to achieve optimal handling and shipping qualities while still maintaining a competitive harvest window, resolving the trade-off between early availability and fruit quality.
Solution Approach 2:
The patent applies preliminary action by allowing the fruit to develop additional ripeness and firmness during the extended 7-day period before harvest. This preliminary maturation process ensures that the fruit reaches optimal eating quality and handling characteristics before being subjected to picking, packing, and shipping operations.
3Productivity
If vigorous growth is pursued, then tree productivity increases, but tree size and management complexity increase
Solution Approach 1:
The patent changes the growth vigor parameter by selecting 'Royal Sonia' to exhibit moderate rather than excessive vigor. This parameter optimization allows the tree to maintain high productivity through regular bearing while keeping tree size manageable and simplifying pruning, harvesting, and overall orchard management operations.

AI summary
A new and distinct variety of cherry tree. The following features of the tree and its fruit are characterized with the tree budded on ‘Mahaleb’ Rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consist of the following combination of desirable features:1. Tree with a vigorous, upright growth habit.2. Regular and productive bearer of medium to large size fruit.3. Fruit with an attractive red skin color.4. Fruit with very good flavor and eating quality with a good balance between acid and sugar.5. Fruit with firm flesh that has good handling and shipping qualities.
