Innovation Solution

The development of the cotton variety 15R537, which involves crossing parental lines, advanced selection methods, and potential genetic transformation to introduce desired traits, allowing for the creation of hybrid seeds and plants with specific characteristics through backcrossing and genetic marker-assisted selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional breeding methods are used to develop new cotton varieties, then genetic diversity can be generated through crossing, but the process requires extensive time and multiple generation advancements to achieve stable superior traits

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

Solution Approach 1:

The patent employs marker-assisted selection to identify and select desired genetic traits at early breeding stages, rather than waiting for full phenotypic expression in later generations. This preliminary identification of target traits accelerates the breeding process by guiding selection decisions before extensive generation advancement is required.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes molecular markers to provide continuous feedback on the genetic composition of breeding lines throughout the breeding process. This feedback mechanism allows breeders to track the inheritance of desired traits across generations and make informed decisions about which lines to advance, thereby reducing the time required to develop stable superior varieties.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If multiple parental lines are crossed to combine desirable traits, then superior cotton varieties with multiple beneficial characteristics can be developed, but the complexity of managing billions of genetic combinations increases significantly

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the complex task of developing multi-trait superior varieties into manageable segments by using molecular markers to track specific genes of interest independently. Rather than attempting to manage all billions of genetic combinations, the breeding program focuses on monitoring and selecting for specific target traits through marker-assisted selection, thereby simplifying the overall breeding process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the parameters used for selection from phenotypic observations to genotypic markers. By using molecular markers to detect and select for desired traits, the breeding program can efficiently manage complex multi-trait combinations without being overwhelmed by the sheer number of possible genetic combinations, as markers provide direct information about the presence of target genes.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If extensive selection and generation advancement are performed to achieve stable superior traits, then new cotton varieties with improved fiber yield and quality can be developed, but the cost and resource requirements of the breeding program increase

Engineering Contradiction:
Improvefiber yieldVSAvoidbreeding resource investment
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent replaces traditional mechanical and visual selection methods with molecular marker-based selection. Instead of relying on labor-intensive phenotypic evaluation and manual selection processes that require extensive resources, the breeding program uses DNA markers to identify and select superior genotypes, thereby reducing the quantity of resources required while maintaining or improving fiber yield outcomes.

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