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 struggle to efficiently integrate these characteristics into stable, high-yielding varieties.

Innovation Solution

The soybean variety XB64E13 is developed through careful breeding and selection, combining traits like resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, with methods for introgressing transgenic or mutant traits to enhance its agronomic characteristics and disease resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine multiple desirable traits, then the variety achieves improved yield and disease resistance, but the breeding process becomes extremely time-consuming (6-12 years)

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

Solution Approach 1:

The patent segments the breeding process by using molecular markers to identify and track specific disease resistance genes independently. This allows breeders to select for multiple traits simultaneously through marker-assisted selection rather than waiting for complete variety development, significantly reducing the time required to achieve reliable disease resistance while maintaining breeding accuracy.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple desirable traits are integrated into a single variety through conventional breeding, then the variety achieves superior agronomic characteristics, but the complexity of the breeding program increases

Engineering Contradiction:
Improveagronomic characteristicsVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms through molecular marker analysis at various stages of the breeding process. By continuously monitoring the presence and combination of desired traits using DNA markers, breeders can make informed decisions about which plants to advance, cross, or discard. This feedback system simplifies the breeding program complexity by providing objective criteria for selection rather than relying on lengthy field trials and phenotypic observations.

Inventive Principle:
Principle #23Feedback

3Stability of the object's composition

If extensive field trials and evaluations are conducted to ensure variety stability, then the variety achieves uniformity and stability, but the resource requirements and time investment increase significantly

Engineering Contradiction:
Improvevariety uniformityVSAvoidresource requirements
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The patent applies preliminary action by using molecular marker analysis early in the breeding process to identify plants with the desired genetic composition. Rather than conducting extensive field trials to prove uniformity, the markers provide preliminary confirmation of genetic stability and homozygosity. This allows breeders to confidently advance only those lines that have already demonstrated the required uniformity, reducing both resource requirements and time investment while maintaining variety stability.

Inventive Principle:
Principle #10Preliminary action
