Solution Overview

Problem

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

Innovation Solution

Development of the soybean variety XB79B13, which is the result of careful breeding and selection, combining traits like resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a comprehensive breeding program involving backcrossing and genetic marker-assisted breeding to ensure homozygosity and phenotypic stability.

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 disease resistance and yield, 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 applies preliminary action by using molecular markers to identify and select plants with desired traits early in the breeding process, before traditional phenotypic selection would occur. This allows breeders to pre-screen large populations for disease resistance and other traits at the seedling stage, dramatically reducing the time required to develop new varieties while maintaining trait reliability

Inventive Principle:
Principle #10Preliminary action

2Productivity

If multiple traits are combined in a single variety through extensive breeding, then the variety achieves superior agronomic performance, 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 applies segmentation by breaking down the complex task of combining multiple traits into separate, manageable components. Each desired trait (disease resistance, yield components, oil composition) is targeted with specific molecular markers, allowing breeders to address each trait independently through marker-assisted selection rather than attempting to improve all traits simultaneously through traditional multi-generational breeding

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If traditional phenotypic selection is used to identify desirable traits, then the variety achieves stable trait expression, but the selection process requires large field trials and extensive resources

Engineering Contradiction:
Improvetrait stabilityVSAvoidresources required
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The patent applies mechanics substitution by replacing the mechanical/physical process of phenotypic selection (visual inspection, field trials, manual measurement) with a biochemical/molecular approach using DNA markers. This substitution allows trait identification at the molecular level without requiring large-scale field trials, reducing resource requirements while maintaining trait stability through accurate genetic selection

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