Solution Overview

Problem

Existing cherry tree varieties face issues with fruit cracking, disease susceptibility, and inconsistent productivity on dwarfing rootstocks, particularly lacking resistance to Monilia disease and having undesirable tree morphology.

Innovation Solution

The 'Korvik' cherry tree variety, resulting from a controlled cross between 'Kordia' and 'Vic', exhibits resistance to Monilia disease, reduced cracking, and improved productivity on dwarfing rootstocks, characterized by its upright growth habit, fewer lenticels, and distinct leaf shape, maintaining its traits through asexual propagation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing cherry tree varieties are used, then they produce fruit, but they are susceptible to Monilia disease and fruit cracking

Engineering Contradiction:

Improvedisease resistanceVSAvoidMonilia disease susceptibility

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by creating a new cherry variety with fundamentally different genetic parameters that confer resistance to Monilia disease and reduced fruit cracking. The variety 'Korvik' exhibits these improved parameters through selective breeding, resulting in trees that maintain productivity while possessing enhanced disease resistance and fruit integrity compared to conventional varieties.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If existing cherry tree varieties are used, then they grow, but they show inconsistent productivity on dwarfing rootstocks

Engineering Contradiction:

Improveyield consistencyVSAvoidproductivity stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent resolves this contradiction by changing the genetic parameters of the cherry variety to achieve consistent productivity on dwarfing rootstocks. The variety 'Korvik' demonstrates reliable and consistent yield performance when grafted onto dwarfing rootstocks, eliminating the variability observed in conventional varieties and enabling predictable production outcomes.

Inventive Principle:

Principle #35Parameter changes

3Shape

If existing cherry tree varieties are used, then they have various growth habits, but they lack desirable upright morphology

Engineering Contradiction:

Improvetree morphologyVSAvoidgrowth habit diversity

Core Design Contradiction:

ShapeVSAdaptability or versatility

Solution Approach 1:

The patent applies parameter changes by selecting for and fixing specific morphological parameters in the variety 'Korvik' to achieve a desirable upright growth habit. This standardized morphology improves orchard management efficiency and aesthetic quality while maintaining the adaptability needed for successful cultivation on dwarfing rootstocks.
