Solution Overview

Problem

The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as high yield, disease resistance, and adaptability to various conditions, but existing methods are slow and prone to directional changes.

Innovation Solution

The introduction of soybean variety 5PQVC29, which is a stable, high-yielding variety with improved traits like resistance to aerial web blight, aphids, and drought, achieved through a combination of genetic manipulation and breeding techniques, including backcrossing and transgenic trait introgression, to enhance agronomic characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional breeding methods are used to develop new soybean varieties, then desirable traits can be combined, but the process takes 6-12 years and requires precise planning with minimal directional changes

Engineering Contradiction:
Improvestability of variety performanceVSAvoidbreeding cycle duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by using molecular markers to identify and select plants with desired traits at early developmental stages, rather than waiting for full maturity to assess traits. This allows breeders to make selection decisions much earlier in the breeding process, significantly reducing the time required to develop new varieties while maintaining reliability through genetic marker-assisted selection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces traditional mechanical/phenotypic selection methods with molecular marker-based selection. Instead of visually assessing plant traits after growth, the invention uses DNA markers to detect desired genetic traits at the molecular level, enabling faster and more accurate selection of plants with target characteristics.

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

2Productivity

If multiple breeding techniques are used to combine desirable traits, then yield and resistance can be improved, but the process becomes more complex and resource-intensive

Engineering Contradiction:
Improveseed yieldVSAvoidbreeding process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by breaking down the complex breeding process into discrete, manageable steps based on specific molecular markers associated with individual traits. Each marker allows for independent selection of specific traits (e.g., disease resistance, yield components), enabling breeders to systematically combine multiple desirable traits without being overwhelmed by the overall complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements feedback mechanisms through molecular marker analysis that provides immediate information about the presence of desired traits in breeding plants. This feedback allows for real-time adjustment of breeding decisions, ensuring that plants with the optimal combination of traits are selected while reducing unnecessary complexity in the breeding process.

Inventive Principle:
Principle #23Feedback
