Solution Overview

Problem

Soybean breeding is challenging due to the plant's self-pollinating nature, which limits genetic diversity and requires intensive research for developing new cultivars with desired traits like yield, disease resistance, and environmental adaptability, and existing methods are inefficient in introducing specific genetic alleles for improved traits.

Innovation Solution

The development of soybean cultivars such as CL1463825, CL1560023, CL1560457, CL1560517, CL1561938, CL1562168, CL1562319, CW1410004, CW1660237, EC1661076, EE1660540, and EW1660267, which incorporate transgenes for herbicide resistance, disease resistance, insect resistance, and modified fatty acid profiles, using techniques like marker-assisted selection and genetic transformation to introduce desired traits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional self-pollinating breeding methods are used, then genetic stability is maintained, but genetic diversity is limited and breeding efficiency is low

Engineering Contradiction:
Improvegenetic diversityVSAvoidbreeding efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent employs marker-assisted selection as an intermediary tool between traditional breeding and genetic transformation. Molecular markers serve as mediators to identify and select plants with desired traits, bridging the gap between phenotypic selection and genotypic precision, thereby improving breeding efficiency while maintaining genetic stability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical phenotypic selection methods with molecular marker-based genotypic selection. Instead of visually assessing plant traits, breeders use DNA markers to directly identify plants carrying desired alleles, substituting mechanical observation with molecular detection to accelerate breeding进程

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

2Measurement precision

If marker-assisted selection is implemented, then selection accuracy is improved, but research and development costs increase

Engineering Contradiction:
Improveselection accuracyVSAvoidresearch and development costs
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent applies marker-assisted selection selectively at critical breeding stages rather than throughout the entire breeding process. By focusing molecular marker analysis on key selection points where trait differentiation is most important, the patent achieves high selection accuracy while limiting the overall cost increase to manageable levels

Inventive Principle:
Principle #16Partial or excessive action
