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 higher seed yield, disease resistance, drought tolerance, and improved fatty acid profiles, while existing methods are limited in efficiently introducing these traits into stable, high-yielding varieties.

Innovation Solution

The soybean variety BG4272 is developed through careful breeding and selection, combining traits like resistance to diseases and abiotic stresses, with methods including backcrossing and transgenic introgression to introduce desired traits, ensuring stability and high yield.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional breeding methods are used to develop new soybean varieties, then desirable traits such as disease resistance and yield can be combined, but the process becomes extremely time-consuming and resource-intensive

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

Solution Approach 1:

Molecular markers serve as intermediaries to identify and track desired traits during breeding. Instead of waiting for phenotypic expression of disease resistance, breeders use molecular markers linked to resistance genes to select plants carrying these traits, dramatically accelerating the breeding process while maintaining reliability of trait introduction

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If multiple desirable traits are combined in a single variety, then the overall performance and stability improve, but the breeding complexity and resource requirements increase significantly

Engineering Contradiction:
Improvevariety stabilityVSAvoidbreeding program complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The breeding program is segmented into distinct phases: identifying individual trait-associated molecular markers, validating marker-trait associations, and then systematically combining multiple traits through marker-assisted selection. This segmentation allows breeders to manage complexity by handling one trait at a time while building toward multi-trait varieties, reducing overall program complexity while achieving stable multi-trait combinations

Inventive Principle:
Principle #1Segmentation

3Productivity

If precise planning and efficient resource use are implemented in breeding programs, then development time can be reduced, but the initial investment in marker development and validation increases

Engineering Contradiction:
Improvebreeding efficiencyVSAvoidresource investment
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

Molecular markers and their associations with desirable traits are developed and validated in advance before large-scale breeding programs begin. This preliminary action creates a ready-to-use toolkit of markers that can be immediately applied to accelerate breeding, reducing long-term resource requirements and increasing productivity once the initial marker development is complete

Inventive Principle:
Principle #10Preliminary action
