Solution Overview

Problem

There is a need for new strawberry plant varieties that are stable, high-yielding, and agronomically sound, with improved characteristics such as fruit size, flavor, and disease susceptibility, which current commercial varieties do not adequately meet.

Innovation Solution

The new strawberry plant variety 'DrisStrawFiftyOne' (Fragaria x ananassa) was developed through a cross between proprietary parents '166T218' and 'DrisStrawForty', exhibiting large, uniform, sweet fruit, flat globose plant habit, early harvest maturity, and moderate rain tolerance, and has been shown to be stable and reproduce true to type through asexual propagation and tissue culture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If current commercial strawberry varieties are used, then cultivation is established, but yield stability and agronomic performance are insufficient

Engineering Contradiction:

ImproveyieldVSAvoidyield stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies parameter changes by selecting and propagating plants with specific phenotypic characteristics (large fruit size, uniform color, early maturity) to create a variety with improved yield and stability. The variety 'DrisStrawFiftyOne' was developed by changing the genetic parameters through controlled crossing and selection, resulting in superior agronomic performance compared to commercial varieties.

Inventive Principle:

Principle #35Parameter changes

2Productivity

If strawberry varieties are improved for high yield and large fruit size, then productivity increases, but disease susceptibility and rain tolerance may worsen

Engineering Contradiction:

Improvefruit size and yieldVSAvoiddisease susceptibility and rain tolerance

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by developing a variety with specific localized adaptations - 'DrisStrawFiftyOne' exhibits moderate rain tolerance and improved disease susceptibility resistance in specific regions while maintaining high productivity. The variety was tested and selected in specific environments (Hillsborough County, Fla.; Huelva, Spain) to optimize local adaptability without compromising overall performance.

Inventive Principle:

Principle #3Local quality

3Productivity

If new strawberry varieties are developed through crossing and selection, then improved characteristics are achieved, but development time and propagation complexity increase

Engineering Contradiction:

Improvevariety performanceVSAvoiddevelopment time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-establishing the genetic cross between proprietary parents '166T218' and 'DrisStrawForty' before the actual variety development. The crossing was performed in advance, and the selected plant was asexually propagated via stolons in 2012, with subsequent testing beginning in 2015. This preliminary preparation accelerated the overall development process while maintaining variety performance.
