Solution Overview

Problem

There is a need for a novel, superior soybean variety that offers improved yield potential, disease resistance, and adaptability to various growing conditions, as existing soybean varieties face challenges such as disease susceptibility and yield stability.

Innovation Solution

The development of the soybean variety 18400RR, which is characterized by its superior agronomic traits including high yield potential, lodging resistance, emergence, disease resistance, and herbicide tolerance, achieved through a breeding process that involves crossing elite soybean varieties and introducing transgenes for desired traits like glyphosate tolerance and insect resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional soybean varieties are used, then existing yield levels are maintained, but disease susceptibility and yield instability occur

Engineering Contradiction:

Improveyield potentialVSAvoidyield stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies composite materials principle by combining multiple genetic traits (disease resistance genes, yield enhancement genes, and stability genes) into a single soybean variety (18400RR). This variety integrates resistance to multiple diseases including soybean cyst nematode, sudden death syndrome, and frogeye leaf spot, while simultaneously maintaining high yield potential and yield stability across varying environmental conditions.

Inventive Principle:

Principle #40Composite materials

2Productivity

If soybean varieties are bred for high yield potential, then productivity increases, but disease resistance may be compromised

Engineering Contradiction:

Improveyield potentialVSAvoiddisease susceptibility

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality principle by providing different resistance traits to different parts of the plant system. Variety 18400RR incorporates specific resistance genes targeting different disease pathways - SCN resistance through cyst nematode resistance genes, SDS resistance through fungal resistance genes, and frogeye leaf spot resistance through bacterial blight resistance genes, while maintaining high yield potential throughout the plant.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If existing soybean varieties are planted, then current agronomic performance is achieved, but adaptability to different growing conditions is limited

Engineering Contradiction:

Improveadaptability to growing conditionsVSAvoidyield potential

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies universality principle by developing variety 18400RR with multi-functional traits that enable it to perform consistently across diverse growing conditions. The variety combines multiple disease resistances, yield enhancement capabilities, and environmental adaptability genes, making it universally suitable for various soil types, climates, and management systems while maintaining high yield potential.

Inventive Principle:

Principle #6Universality (Multi-functionality)
