Solution Overview

Problem

Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits like disease resistance, drought tolerance, and improved fatty acid profiles, but face challenges in efficiently combining these traits in a single variety.

Innovation Solution

Development of the soybean variety XBP18007, which is the result of careful breeding and selection, combining traits such as resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a comprehensive breeding program involving cross-pollination and genetic marker profiling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding processes are used to combine multiple desirable traits, then disease resistance and yield improvement are achieved, but the breeding process becomes extremely time-consuming and resource-intensive

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

Solution Approach 1:

The patent employs molecular marker-assisted selection (MAS) which provides feedback on the genetic composition of breeding plants at the DNA level. This allows breeders to track and select for multiple desirable traits simultaneously without waiting for phenotypic expression, dramatically reducing the time required to develop resistant varieties while maintaining reliable disease resistance through precise genetic selection

Inventive Principle:
Principle #23Feedback

2Productivity

If multiple desirable traits are combined in a single soybean variety through extensive breeding, then agronomic performance is improved, but the complexity of the breeding program increases significantly

Engineering Contradiction:
Improvegrain yieldVSAvoidbreeding program complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the breeding process into distinct molecular marker-assisted selection steps for different traits. Each desirable trait (disease resistance, yield components, stress tolerance) can be tracked and selected for independently using specific molecular markers, allowing complex multi-trait varieties to be developed through systematic, modular selection rather than random cross-breeding, thereby reducing program complexity while improving productivity

Inventive Principle:
Principle #1Segmentation

3Reliability

If soybean varieties are developed with altered fatty acid profiles for improved nutrition and oxidative stability, then oil quality is enhanced, but the breeding process requires additional years of development

Engineering Contradiction:
Improveoxidative stabilityVSAvoidvariety development duration
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent applies preliminary action by using molecular markers to identify and select for fatty acid profile traits at the seedling stage rather than waiting for maturity and oil extraction analysis. This allows breeders to track inheritance of fatty acid composition traits through generations and make selection decisions early in the breeding process, significantly reducing the overall development duration while ensuring reliable oxidative stability in the final variety

Inventive Principle:
Principle #10Preliminary action
