Solution Overview

Problem

Cotton breeding is a time-consuming process that involves unpredictability in developing new varieties due to the complexity of inheritance and the lack of control at the DNA level, leading to high research costs and inefficiencies in identifying genetically superior plants.

Innovation Solution

The development of the cotton variety 04T056, which is uniform for breeding purposes and can be reproduced under self-pollinating or sib-pollinating conditions, along with methods for crossing this variety with itself or other plants to produce hybrid seeds and plants, enabling the introduction of desired traits through 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 trait combinations can be explored, but the process becomes time-consuming and unpredictable due to complexity of inheritance

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

Solution Approach 1:

The patent replaces conventional mechanical breeding methods (cross-pollination, selection, and generation advancement) with molecular biology techniques including DNA extraction, PCR amplification of specific loci, and genetic transformation. This substitution allows direct manipulation and introduction of desired traits at the molecular level, bypassing the time-consuming process of traditional breeding while maintaining genetic diversity through controlled introduction of specific genetic variations.

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

2Adaptability or versatility

If conventional breeding procedures are used, then new genetic combinations can be generated, but control at the DNA level is lacking leading to unpredictability in final varieties

Engineering Contradiction:
Improvegenetic combinationVSAvoidDNA level control
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent changes the parameter of genetic modification from indirect phenotypic selection to direct genotypic manipulation. By using PCR to amplify specific DNA loci and employing genetic transformation techniques, the invention enables precise control over which genetic combinations are introduced into the cotton variety. This allows the breeder to select and introduce specific alleles at known locations in the genome, providing DNA-level control over the final variety characteristics.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If repeated selfing and selection are performed to develop new varieties, then desirable traits can be combined, but large amounts of research monies are expended due to unpredictability

Engineering Contradiction:
Improvetrait combinationVSAvoidresearch cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent introduces molecular marker-based feedback mechanisms into the breeding process. By using PCR amplification of specific DNA loci, the invention provides real-time feedback on the genetic composition of breeding lines. This allows researchers to identify and select plants with desired genetic combinations at early stages, rather than waiting for phenotypic expression. The feedback system enables informed decision-making about which lines to advance, reducing the number of unsuccessful breeding attempts and associated costs.

Inventive Principle:
Principle #23Feedback

4Measurement precision

If superior plants are identified through observation and replication, then genetically valuable individuals can be found, but the process is inefficient due to masking by environmental factors

Engineering Contradiction:
Improvegenetic worth estimationVSAvoididentification efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces phenotypic observation and environmental performance evaluation with direct genotypic analysis using PCR and DNA marker techniques. By substituting mechanical/visual assessment methods with molecular biology methods, the invention directly measures the genetic composition of plants without the confounding influence of environmental factors. This allows for precise identification of genetically superior individuals based on their actual DNA sequence and genetic markers, rather than their phenotypic performance which may be masked by environmental conditions.

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