Solution Overview

Problem

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

Innovation Solution

The development of a novel soybean variety, XB29P12, which is the result of careful breeding and selection, combining traits like resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, achieved through a comprehensive breeding program involving cross-pollination and backcrossing techniques to introduce desired traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional soybean breeding methods are used to combine multiple desirable traits, then trait combination is achieved, but the breeding process becomes time-consuming and resource-intensive

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding 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 track specific trait loci independently. This allows breeders to select for multiple traits simultaneously through marker-assisted selection rather than relying on traditional time-consuming phenotypic selection across multiple generations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary action by using molecular markers to pre-identify desirable trait combinations in early breeding generations. This preliminary genetic analysis enables selection decisions to be made before phenotypic expression is visible, significantly reducing the time required to develop new varieties.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If multiple desirable traits are combined in a single variety, then variety improvement is achieved, but the complexity of the breeding program increases

Engineering Contradiction:
Improvevariety improvementVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms through molecular marker analysis that provides real-time information on the presence and combination of desirable traits. This feedback allows breeders to make informed selection decisions at each generation, monitoring progress toward the target variety composition and adjusting breeding strategies accordingly.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces molecular markers as intermediaries between the breeder and the target traits. These markers serve as measurable indicators that simplify the complex task of tracking multiple trait combinations, allowing breeders to indirectly select for desired traits through easily detectable marker patterns.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If extensive breeding and selection is performed to achieve stable high-yielding varieties, then yield and stability are improved, but resource consumption increases

Engineering Contradiction:
Improveyield and stabilityVSAvoidresource consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent replaces traditional mechanical phenotypic selection methods with molecular marker-based genetic analysis. This substitution allows for more efficient and accurate identification of desirable trait combinations, reducing the number of breeding cycles and field trials needed to develop stable high-yielding varieties, thereby conserving resources.

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