Solution Overview

Problem

The development of new cotton varieties is a time-consuming and unpredictable process due to the complexity of inheritance and the need to identify genetically superior plants, which requires extensive resources and repeated testing under various environmental conditions.

Innovation Solution

The cotton variety 04T042, which is uniform and reproducible, is developed through specific breeding methods including crossing with itself or other plants, and can be used to produce hybrid seeds and plants with desired traits such as higher fiber yield, disease resistance, and drought tolerance, utilizing techniques like backcrossing and genetic transformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to develop new cotton varieties, then genetic diversity and adaptability are improved, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:
Improvegenetic diversityVSAvoidbreeding process duration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits before initiating the breeding program. This advance preparation of genetically superior parents with known characteristics accelerates the breeding process while maintaining genetic diversity, as the foundation is laid before the actual crossing and selection phases begin

Inventive Principle:
Principle #10Preliminary action

2Reliability

If extensive testing and evaluation are conducted to identify superior plants, then variety reliability is improved, but resource consumption and process complexity increase

Engineering Contradiction:
Improvevariety performance consistencyVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical/phenotypic evaluation methods with molecular marker-assisted selection. Instead of relying solely on visual observation and environmental performance testing, the invention uses DNA-based markers to identify and select plants with desired genetic traits, thereby reducing the complexity of extensive field testing while improving reliability through direct genetic assessment

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If repeated selfing and selection are performed to develop pureline varieties, then manufacturing precision is improved, but productivity decreases

Engineering Contradiction:
Improvegenetic uniformityVSAvoidbreeding output per year
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent uses molecular markers as copies or proxies for complex genetic traits. Instead of performing multiple generations of selfing and phenotypic selection to achieve genetic uniformity, the invention copies the desired genetic information through marker-linked selection, allowing breeders to identify and propagate uniform genotypes more rapidly and with greater precision

Inventive Principle:
Principle #26Copying
