Solution Overview

Problem

Cotton breeding is a time-consuming and unpredictable process due to the complexity of inheritance and the lack of control over genetic combinations, making it difficult to develop superior cultivars with desired traits such as higher fiber yield, disease resistance, and environmental tolerance.

Innovation Solution

The development of cotton cultivar DP 110 RF, which incorporates specific genetic traits through backcrossing and genetic engineering, including herbicide resistance and insect resistance, using molecular markers for precise selection and regeneration of plants with desired characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional breeding methods are used to develop new cotton cultivars, then genetic diversity and trait combination are improved, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:

Improvetrait combinationVSAvoidbreeding process duration

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

Molecular markers provide feedback on the genetic composition of breeding lines, allowing breeders to track desired traits through generations and make informed selection decisions, thereby reducing the time and unpredictability of conventional breeding processes

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent replaces phenotypic selection (mechanical/physical observation) with molecular marker-based genotypic selection, enabling direct detection of genetic traits without waiting for phenotypic expression, thus accelerating the breeding process

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If multiple generations of selection and testing are conducted to ensure cultivar superiority, then trait reliability is improved, but the development time and resource expenditure increase

Engineering Contradiction:

Improvecultivar superiorityVSAvoidevaluation period

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Molecular marker analysis is performed early in the breeding process to pre-identify lines carrying desired genetic traits, allowing superior lines to be selected before phenotypic evaluation, thereby reducing the time required for multi-generation testing while maintaining reliability

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If large population sizes are grown to generate sufficient genetic combinations, then genetic diversity is improved, but the resource requirements and complexity of management increase

Engineering Contradiction:

Improvegenetic combinationsVSAvoidbreeding program complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts specific genetic information using molecular markers from a subset of individuals, eliminating the need to grow and evaluate large populations, thereby reducing program complexity and resource requirements while maintaining genetic diversity

Inventive Principle:

Principle #2Taking out (Extraction)
