Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing grape varieties lack high vigor, resistance to downy and powdery mildew, and consistent fruit production in temperate regions with specific climate conditions.

Innovation Solution

The development of the 'KERSUS' grape variety, resulting from a controlled cross between SK-00-1/7 and Pinot Blanc, which exhibits high vigor, circular shaped leaves, medium weight fruit clusters, early-medium harvesting time, and resistance to downy and powdery mildew, adapted to temperate regions with average yearly temperatures around 13°C and minimum winter temperatures of -20°C.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing grape varieties are cultivated in temperate regions, then they can produce fruit, but they lack high vigor and resistance to downy and powdery mildew

Engineering Contradiction:

Improveresistance to downy and powdery mildewVSAvoidvigor and consistent fruit production

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The invention combines the resistance traits from Pinot Blanc (resistance to downy and powdery mildew) with the vigor and fruit production characteristics from SK-00-1/7 through controlled cross-breeding, creating a new variety that exhibits both high vigor and disease resistance simultaneously

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If grape varieties are selected for disease resistance, then they can survive in temperate climates, but they may lack consistent fruit production

Engineering Contradiction:

Improvedisease resistanceVSAvoidconsistent fruit production

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The cross-breeding program merges the disease resistance genes from Pinot Blanc with the productive vigor of SK-00-1/7, resulting in KERSUS that maintains both traits through selective breeding and propagation

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If grape varieties are adapted to specific climate conditions, then they can thrive in those regions, but they may not perform consistently across different temperate regions

Engineering Contradiction:

Improveadaptation to temperate regionsVSAvoidconsistent fruit production

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The new variety KERSUS is bred to possess universal adaptability across temperate regions through its hybrid heritage, combining the climate adaptability of Pinot Blanc with the vigorous growth and consistent production traits of SK-00-1/7, enabling it to thrive in various temperate climates including North-Eastern Italy

Inventive Principle:

Principle #6Universality (Multi-functionality)
