Solution Overview

Problem

Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits like disease resistance, drought tolerance, and improved fatty acid profiles, but face challenges in efficiently combining these traits in a single variety.

Innovation Solution

Development of the soybean variety XBP52005, which is the result of careful breeding and selection, combining traits such as resistance to diseases, insects, drought, and improved agronomic characteristics, along with specific methods for producing and characterizing this variety, including genetic marker profiles and backcrossing techniques to introduce new traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional soybean breeding processes are used to combine multiple desirable traits (disease resistance, drought tolerance, improved fatty acid profiles), then the variety achieves superior agronomic characteristics, but the breeding process becomes extremely time-consuming and resource-intensive

Engineering Contradiction:
Improvecombination of desirable traitsVSAvoidbreeding process duration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments the breeding process by using molecular markers to identify and select specific trait combinations in early generations, rather than waiting for complete variety development. This allows parallel evaluation of multiple trait combinations, significantly reducing the time required to achieve superior agronomic characteristics.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary action by performing molecular marker-based selection in early breeding generations (F2-F4) to pre-identify plants with desired trait combinations. This preliminary screening eliminates the need for lengthy field testing of all possible combinations, accelerating the breeding process while maintaining trait combination quality.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If multiple generations of breeding and selection are performed to achieve stable, high-yielding varieties, then the variety achieves genetic stability and uniformity, but the development process requires six to twelve years

Engineering Contradiction:
Improvegenetic stabilityVSAvoidbreeding efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent replaces the traditional mechanical/phenotypic selection system with a molecular marker-based selection system. By using DNA markers linked to desirable traits, the patent can predict trait expression without waiting for phenotypic manifestation, thereby achieving genetic stability assessment much earlier in the breeding process and improving overall breeding efficiency.

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

Solution Approach 2:

The patent implements feedback mechanisms through molecular marker analysis that provides early information about genetic composition and trait inheritance patterns. This feedback allows breeders to make informed selection decisions in early generations, adjusting breeding strategies to achieve desired genetic stability more quickly without sacrificing uniformity.

Inventive Principle:
Principle #23Feedback

3Reliability

If extensive field testing and characterization are conducted to ensure variety stability and uniformity, then the variety achieves reliable performance, but the resource requirements and complexity of the breeding program increase

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

Solution Approach 1:

The patent introduces molecular markers as intermediary tools that mediate between genetic composition and phenotypic expression. These markers serve as reliable indicators of desirable traits, allowing breeders to assess variety performance reliability without conducting extensive field testing at every breeding stage, thereby reducing program complexity while maintaining reliability.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the assessment parameters from phenotypic observations (which require extensive field testing) to molecular marker profiles (which can be analyzed in the laboratory). This parameter change enables reliable variety characterization with reduced field trial requirements, lowering breeding program complexity while maintaining performance reliability through molecular verification of trait inheritance.

Inventive Principle:
Principle #35Parameter changes
