Sinfonia Apple Tree Scab Resistance and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apple tree varieties lack sufficient natural resistance to scab and do not combine high-quality flavor, aroma, and sustainability effectively, particularly in terms of storage ability and disease resistance.
Innovation Solution
The development of a new apple tree variety, 'Sinfonia', resulting from a controlled breeding program, which exhibits improved resistance to scab, bi-colored intense light red overcolor, large size, weak vigor, open habit, high sugar content, and long storage ability, achieved through asexual reproduction by budding and grafting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing apple tree varieties are used, then they are easy to cultivate, but they lack sufficient natural resistance to scab and do not combine high-quality flavor, aroma, and storage ability effectively
Solution Approach 1:
The patent combines multiple desirable traits from different parent varieties into a single new variety 'Sinfonia'. The female parent 'Co-op 25' contributes disease resistance and the male parent 'CIVCP-142' contributes high sugar content and aroma. Through controlled cross-breeding, these separate advantages are merged into one variety that exhibits both scab resistance and superior fruit quality characteristics.
Solution Approach 2:
The new variety 'Sinfonia' possesses natural resistance to scab disease, eliminating the need for chemical fungicide applications. The variety serves itself by having built-in defense mechanisms against disease, reducing external intervention requirements and aligning with sustainable cultivation practices.
2Duration of action of stationary object
If existing apple tree varieties are used, then they can be cultivated with standard practices, but they do not achieve long storage ability and high sugar content simultaneously
Solution Approach 1:
The patent merges the storage ability trait from parent variety 'Co-op 25' with the high sugar content trait from parent variety 'CIVCP-142' in the new variety 'Sinfonia'. This combination allows the fruit to maintain both extended shelf life and superior sweetness, traits that were not simultaneously present in the parent varieties when grown under comparable conditions.
3Reliability
If existing apple tree varieties are used, then they maintain acceptable fruit quality, but they lack intense aroma and flavor characteristics
Solution Approach 1:
The new variety 'Sinfonia' inherently produces intense aroma and flavor characteristics without requiring special cultivation techniques or additional inputs. The variety self-generates these quality attributes through its genetic composition, particularly inheriting the high sugar content and aromatic properties from parent 'CIVCP-142', making excellent quality the default outcome of standard cultivation.

AI summary
A new and distinct Malus domestica Mill. apple tree named ‘Sinfonia’ particularly characterized by having a mid-season ripening time, with high productivity and precocious fruit bearing. The fruit are of big size, with conic shape. The overcolor is light red over green background. The flesh is very firm with fine texture and good juiciness. The flavor is slightly acidic with a global excellent eating quality. The fruit keeps very well on the tree, as well as in cold storage.
