Solution Overview

Problem

The challenge in soybean breeding is to develop stable, high-yielding varieties that are resistant to diseases, insects, and abiotic stresses while maintaining desirable agronomic characteristics, which is a time-consuming process requiring precise planning and resource management.

Innovation Solution

The development of the soybean variety 95Y21, which combines improved traits such as disease resistance, insect tolerance, and abiotic stress tolerance through careful breeding and selection, involving crossing and introgression of transgenic or mutant traits, and characterization using genetic markers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional breeding methods are used to develop soybean varieties with improved traits, then disease resistance and yield are improved, but the breeding process becomes time-consuming and resource-intensive

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding process duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-characterizing soybean accessions using molecular markers and high-throughput phenotyping before breeding crosses. This advance characterization allows breeders to select parents with desired traits more efficiently, reducing the time required for traditional breeding while maintaining disease resistance improvements.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through molecular marker-assisted selection and genomic prediction models that provide real-time information on trait inheritance and performance. This feedback mechanism allows breeders to make informed decisions about which crosses to pursue, accelerating the breeding process while ensuring disease resistance is maintained or improved.

Inventive Principle:
Principle #23Feedback

2Productivity

If multiple traits are combined in a single soybean variety through breeding, then agronomic performance is improved, but the complexity of the breeding program increases

Engineering Contradiction:
Improvegrain yieldVSAvoidbreeding program complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies universality by developing a integrated breeding platform that simultaneously evaluates multiple traits including yield, disease resistance, and abiotic stress tolerance using the same set of molecular markers and phenotyping protocols. This multi-functional approach allows breeders to select for multiple traits in a single breeding program, improving grain yield without proportionally increasing program complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent utilizes parameter changes by applying genomic selection and molecular marker technologies that transform the breeding process from phenotype-based to genotype-based selection. This parameter change allows for more precise and efficient selection of plants with desired combinations of traits, reducing the complexity of managing multi-trait breeding programs while improving overall agronomic performance.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If soybean varieties are developed with altered fatty acid profiles for improved nutrition, then nutritional quality is enhanced, but the breeding and selection process becomes more complex

Engineering Contradiction:
Improvenutritional qualityVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies mechanics substitution by replacing traditional, labor-intensive phenotypic analysis of fatty acid profiles with molecular marker-based prediction and genomic selection. This substitution of mechanical/chemical analysis with molecular biology techniques simplifies the breeding process for developing varieties with altered fatty acid profiles, reducing program complexity while maintaining or improving nutritional quality.

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