Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding varieties that combine desirable traits such as disease resistance, drought tolerance, and improved agronomic qualities, which are often unpredictable and time-consuming due to the complexity of genetic inheritance and environmental factors.

Innovation Solution

The development of the soybean variety A1026577, which is adapted for early to mid-growing regions, involves a specific breeding history and methods like backcrossing, genetic transformation, and marker-assisted selection to introduce desired traits like herbicide resistance, disease resistance, and improved nutritional quality, while maintaining the variety's morphological and physiological characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional breeding methods are used to combine multiple desirable traits, then trait combination complexity increases, but breeding time and unpredictability increase significantly

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Marker-assisted selection uses molecular markers to provide feedback on the presence of desired traits during breeding, allowing breeders to track and select for multiple traits simultaneously with predictable outcomes, dramatically reducing breeding time compared to conventional phenotypic selection

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces conventional phenotypic observation and selection methods with molecular marker-based genotypic selection, substituting mechanical/visual assessment with biochemical analysis to achieve faster and more accurate trait combination

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

2Adaptability or versatility

If multiple traits are combined through conventional breeding, then desirable trait combination is achieved, but selection precision and predictability decrease

Engineering Contradiction:
Improvedesirable traits combinationVSAvoidselection precision
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

Molecular markers provide precise feedback on the genetic composition of breeding materials, enabling selection based on actual genotype rather than phenotypic expression, which significantly improves selection precision and predictability for complex trait combinations

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent substitutes phenotypic measurement with genotypic measurement using molecular markers, replacing imprecise visual assessment with accurate biochemical detection to achieve high selection precision

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

3Productivity

If extensive breeding programs are implemented to improve yield and quality, then variety performance is enhanced, but program complexity and resource requirements increase

Engineering Contradiction:
Improveyield and qualityVSAvoidbreeding program complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent extracts and isolates specific molecular markers associated with desirable traits, separating the selection function from complex phenotypic evaluation, thereby simplifying breeding program design and implementation while maintaining high productivity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Molecular marker technology replaces complex multi-trait phenotypic evaluation with simple DNA-based assays, reducing breeding program complexity and resource requirements while improving yield and quality outcomes

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