Solution Overview

Problem

Soybean breeding faces challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved fatty acid profiles, which are time-consuming and resource-intensive, with only a small percentage of new varieties being selected for commercial use.

Innovation Solution

The development of the soybean variety XB20W09, which combines traits like glyphosate resistance, multi-race Phytophthora resistance, and SCN resistance, achieved through careful breeding and selection, allowing for improved yield potential and stress tolerance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to develop new varieties with multiple desirable traits, then the variety can achieve improved yield potential, disease resistance, and stress tolerance, but the breeding process becomes extremely time-consuming and resource-intensive, with only a small percentage of new varieties being selected for commercial use

Engineering Contradiction:
Improvevariety stabilityVSAvoidbreeding cycle duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-establishing a structured breeding program with defined objectives, selecting parent lines with specific desirable traits before the actual crossing begins, and planning multiple generations of selection and evaluation in advance. This systematic preparation reduces the overall time required by avoiding reactive adjustments during the breeding process.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The breeding program is segmented into distinct phases: parent line selection, controlled crossing, multi-generation selection, field testing, and variety release. Each phase has specific criteria and objectives, allowing efficient progression through manageable steps rather than a monolithic process, thereby reducing total breeding time while maintaining variety stability.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If breeding programs aim to combine multiple desirable traits (yield, disease resistance, stress tolerance) in a single variety, then the variety achieves superior performance, but the complexity of the breeding process increases significantly

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple desirable traits into a single variety through systematic crossing and selection. Parent lines are selected that each contribute specific traits (yield, disease resistance, stress tolerance), and through controlled crossing and multi-generation selection, these traits are combined in a unified variety that exhibits superior performance across multiple parameters.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The breeding program is designed to produce a variety that serves multiple functions simultaneously: high yield production, disease resistance, stress tolerance, and adaptability to different environments. This multi-functional approach consolidates what would otherwise require separate breeding programs into a single versatile variety.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If only a small percentage of new varieties are selected for commercial use despite creating over 500,000 potential varieties yearly, then the selection process maintains high standards, but the resource investment required to evaluate and develop each variety becomes inefficient

Engineering Contradiction:
Improvevariety selection precisionVSAvoidvariety development efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent implements feedback mechanisms through systematic field testing and evaluation at multiple stages. Performance data from field trials is used to select the most promising varieties for advancement, while less successful varieties are eliminated early in the process. This feedback-driven selection maintains high standards while improving efficiency by focusing resources on varieties with proven potential.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The breeding program creates more potential varieties than will ultimately be released (excessive action), but uses efficient selection criteria and staged evaluation to manage this surplus. By establishing a pipeline that continuously generates new varieties while systematically evaluating them against clear objectives, the program maintains high selection precision without proportionally increasing resource waste.

Inventive Principle:
Principle #16Partial or excessive action
