Solution Overview

Problem

The development of new corn inbred lines is a time-consuming and unpredictable process due to the complexity of combining desirable traits like yield, disease resistance, and environmental adaptability, often requiring extensive research and resources without guaranteed results.

Innovation Solution

The introduction of the inbred corn line ML8, which is a yellow dent corn with superior characteristics, adapted for specific regions, and methods for producing hybrid seeds and plants with traits such as male sterility, disease resistance, and improved nutritional quality through genetic modification and backcrossing techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional corn breeding methods are used to combine desirable traits, then genetic diversity and trait combination potential are improved, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:
Improvetrait combination capabilityVSAvoidbreeding cycle duration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-establishing inbred line ML8 with desired traits (disease resistance, yield potential, adaptability) through extensive breeding work before it is needed. This pre-developed inbred line can then be rapidly crossed with other lines to produce hybrids, eliminating the need to perform lengthy breeding cycles at the hybridization stage. The inbred line serves as a pre-prepared genetic resource that accelerates the overall breeding process.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If extensive breeding programs are conducted to develop superior inbred lines, then genetic quality and yield potential are improved, but resource consumption and program complexity increase

Engineering Contradiction:
Improvegenetic quality consistencyVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by standardizing key genetic parameters of inbred line ML8, including disease resistance levels, yield potential, and adaptability characteristics. By establishing consistent genetic parameters through controlled breeding and selection, the patent achieves reliable genetic quality without requiring continuously expanding complex breeding programs. The inbred line represents a standardized genetic solution that can be repeatedly used across multiple hybrid combinations.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If multiple breeding cycles and evaluations are performed to ensure superior hybrid performance, then hybrid yield and agronomic traits are improved, but the number of steps and operational complexity increase

Engineering Contradiction:
Improvehybrid yield performanceVSAvoidbreeding process steps
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies self-service by developing inbred line ML8 with inherently superior traits (disease resistance, yield potential, stress tolerance) that automatically contribute to hybrid performance without requiring additional breeding interventions. The inbred line's genetic composition provides built-in advantages that express themselves directly in hybrid offspring, reducing the need for multiple evaluation cycles and complex selection processes to ensure superior performance.

Inventive Principle:
Principle #25Self-service
