Solution Overview

Problem

There is a need for a new strawberry cultivar that combines desirable traits such as earlier fruit production, compact plant habit, increased fruit size with softer texture, improved rain tolerance, and resistance to pests and diseases, which existing strawberry cultivars like 'Driscoll Ojai' and 'Driscoll El Dorado' do not fully address.

Innovation Solution

The development of the strawberry cultivar 'DrisStrawThirteen' (Fragaria×ananassa), which results from a cross between '2K297' and 'Driscoll Ojai', exhibits distinct characteristics including larger fruit, softer texture, earlier fruiting, compact habit, darker foliage, and enhanced rain tolerance, as well as moderate resistance to various pests and diseases, achieved through asexual propagation and testing in Ventura and Shasta counties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing strawberry cultivars like 'Driscoll Ojai' and 'Driscoll El Dorado' are used, then they provide basic fruit production, but they fail to combine earlier fruit production, compact habit, increased fruit size with softer texture, improved rain tolerance, and resistance to pests and diseases

Engineering Contradiction:

Improverain toleranceVSAvoidresistance to pests and diseases

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The strawberry cultivar 'DrisStrawThirteen' combines genetic material from two parent cultivars through controlled cross-breeding, creating a composite genetic structure that integrates desirable traits including rain tolerance, pest resistance, and improved fruit characteristics that neither parent possessed alone

Inventive Principle:

Principle #40Composite materials

2Productivity

If existing strawberry cultivars are used, then they provide fruit production, but they do not produce larger fruit with softer texture earlier in the season

Engineering Contradiction:

Improvefruit production timing and sizeVSAvoidfruit texture

Core Design Contradiction:

ProductivityVSShape

Solution Approach 1:

The cross-breeding program selectively combined genetic parameters from parent cultivars to optimize fruit development timing, size, and texture characteristics, resulting in a cultivar that produces larger, softer fruit earlier in the season compared to existing varieties

Inventive Principle:

Principle #35Parameter changes

3Shape

If existing strawberry cultivars are used, then they provide basic plant habit, but they do not provide improved plant compactness

Engineering Contradiction:

Improveplant habit compactnessVSAvoidplant structure

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The new cultivar exhibits modified local characteristics in plant architecture, including compact growth habit and darker foliage, while maintaining essential plant functions, creating a more space-efficient plant structure suitable for high-density planting

Inventive Principle:

Principle #3Local quality
