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

The development of the soybean variety XBP24003, 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 process involving cross-pollination, backcrossing, and molecular marker-assisted breeding to ensure homozygosity and phenotypic stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to combine multiple desirable traits in soybean varieties, then trait combination is achieved, but the breeding process becomes time-consuming and resource-intensive

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

Solution Approach 1:

The patent replaces traditional mechanical breeding methods (manual cross-pollination, field selection, and phenotypic evaluation) with molecular marker-assisted selection systems. DNA markers are used to identify and select plants with desired traits at the molecular level, eliminating the need for time-consuming multi-year field trials and manual trait assessment, thereby dramatically reducing breeding cycle time while maintaining trait combination effectiveness

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

2Stability of the object's composition

If multiple generations of breeding and selection are performed to achieve phenotypic stability, then variety stability is improved, but the development timeline extends to 6-12 years

Engineering Contradiction:
Improvephenotypic stabilityVSAvoidbreeding efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent substitutes traditional phenotypic selection requiring multiple generations of field testing with genotypic selection using molecular markers. DNA-based identification of desired traits allows breeders to select stable varieties in a single generation rather than advancing through multiple generations, thereby maintaining phenotypic stability while dramatically improving breeding efficiency and reducing development time from 6-12 years to a fraction of that time

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

3Reliability

If comprehensive breeding programs are implemented to achieve high yield and disease resistance, then variety performance is improved, but resource requirements and program complexity increase

Engineering Contradiction:
Improvevariety performanceVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces complex, resource-intensive comprehensive breeding programs with a streamlined molecular marker-assisted selection system. Instead of monitoring multiple phenotypic traits across numerous field trials requiring extensive human labor and infrastructure, the system uses DNA markers to simultaneously assess multiple traits including yield, disease resistance, and other performance characteristics, thereby maintaining high variety performance while reducing program complexity and resource requirements

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