Solution Overview

Problem

Existing tomato breeding methods fail to produce stable, high-yielding hybrids with superior fruit quality and agronomic traits consistently.

Innovation Solution

Development of a hybrid tomato plant designated CURIOSO, which can be propagated through seeds, tissue culture, or vegetative methods, and enhanced through genetic modifications using New Breeding Techniques like CRISPR/Cas endonucleases to introduce desired traits such as disease resistance, drought tolerance, and improved fruit characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional tomato breeding methods are used, then fruit production can be achieved, but yield stability and consistency across generations are insufficient

Engineering Contradiction:
Improvefruit yieldVSAvoidhybrid stability
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by developing and maintaining pure inbred parental lines through multiple generations of self-pollination and selection before hybridization. This preliminary purification of parental lines ensures that when crossed, they produce stable F1 hybrids with consistent, high-yielding fruit production across generations, resolving the contradiction between productivity and stability.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple breeding objectives are pursued simultaneously, then comprehensive improvement is possible, but breeding complexity increases

Engineering Contradiction:
Improveagronomic qualityVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the breeding program into distinct phases: developing inbred parental lines with specific traits, crossing them to produce F1 hybrids, and separately evaluating different agronomic qualities (yield, fruit quality, disease resistance). This segmentation allows comprehensive improvement of multiple traits while managing complexity through structured, modular breeding steps.

Inventive Principle:
Principle #1Segmentation

3Manufacturing precision

If hybridization is performed to improve fruit qualities, then superior fruit characteristics can be obtained, but maintaining hybrid vigor and stability becomes difficult

Engineering Contradiction:
Improvefruit qualityVSAvoidhybrid consistency
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent applies parameter changes by controlling the genetic parameters of parental lines through extended inbreeding and selection, ensuring they are highly homozygous. This parameter control (genetic purity of parents) directly influences the consistency and reliability of F1 hybrid fruit quality, maintaining both superior characteristics and hybrid stability across generations.

Inventive Principle:
Principle #35Parameter changes
