Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current grapevine varieties lack resistance to downy and powdery mildew and sufficient winter hardiness, limiting their adaptability and yield in challenging environmental conditions.

Innovation Solution

The 'TRASEMIS' grapevine variety, resulting from a hybridization program between 'SK-00-1/10' and 'TRAMINER', exhibits unique characteristics such as leaf blistering, medium-sized blades, resistance to downy and powdery mildew, and winter hardiness up to −23° C, achieved through asexual reproduction and grafting onto K5BB rootstock.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional grapevine varieties are used, then they have simple cultivation requirements, but they lack resistance to downy and powdery mildew and sufficient winter hardiness

Engineering Contradiction:

Improvedisease resistance and winter hardinessVSAvoidadaptability to diverse environmental conditions

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies hybridization to create a composite grapevine variety 'TRASEMIS' by crossing two parent varieties 'SK-00-1/10' and 'TRAMINER'. This combines the disease resistance and winter hardiness traits from the parents to produce offspring with improved reliability, specifically resistance to downy mildew, powdery mildew, and cold temperatures down to -23° C.

Inventive Principle:

Principle #40Composite materials

2Reliability

If grapevine varieties with improved disease resistance are developed, then reliability improves, but the complexity of breeding programs increases

Engineering Contradiction:

Improveresistance to downy and powdery mildewVSAvoidbreeding program complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a planned hybridization program where the crossing of parent varieties was performed in advance (2009), and the desired traits were selected during the growing period (2017). This preliminary breeding action established the disease resistance characteristics before commercial propagation, simplifying subsequent cultivation.

Inventive Principle:

Principle #10Preliminary action

3Temperature

If grapevine varieties with enhanced winter hardiness are created, then they can survive lower temperatures, but their leaf characteristics and disease resistance may be compromised

Engineering Contradiction:

Improvewinter hardiness up to −23° CVSAvoidresistance to downy and powdery mildew

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The hybrid variety 'TRASEMIS' combines traits from both parent varieties to achieve a balance of characteristics. The cross between 'SK-00-1/10' and 'TRAMINER' produces offspring that inherit winter hardiness (resisting up to -23° C) while maintaining resistance to downy mildew and powdery mildew, along with desirable leaf characteristics including medium-sized blades with blistering and circular shape.
