Solution Overview

Problem

The development of new hybrid corn varieties is a slow and costly process that requires expertise, and existing hybrid corn varieties lose commercial competitiveness over time, necessitating a continuous need for novel varieties with improved characteristics to enhance yield production and provide flexibility against insects, weeds, and diseases.

Innovation Solution

The development of a new yellow dent hybrid corn variety, X12505, produced from a cross of inbred varieties 5ABSM0035 and LLD06BM, with specific physiological and morphological characteristics, and the use of treated seeds to enhance resistance to adverse conditions such as cold, drought, and diseases, along with processes for producing novel inbred and hybrid plants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If hybrid corn varieties are developed through traditional breeding processes, then yield and performance are improved, but the development time and cost increase significantly

Engineering Contradiction:
ImproveyieldVSAvoiddevelopment time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing parent inbred lines with specific desirable traits before hybridization. The inbred parents are rigorously evaluated for yield components, plant health, and adaptability characteristics beforehand, so that when crossed, they produce hybrids with predictable and improved performance. This preliminary characterization accelerates the breeding process by reducing the need for extensive multi-generation testing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent employs parameter changes by systematically varying and optimizing key genetic parameters through controlled crosses of inbred lines with different trait profiles. By adjusting the genetic composition parameters of parent lines and selecting specific combinations, the breeders can tune the hybrid's yield, maturity, and adaptability parameters to match target production environments, thereby improving productivity without proportionally increasing development time.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If existing hybrid corn varieties are used over time, then established performance is maintained, but commercial competitiveness is lost

Engineering Contradiction:
Improveperformance consistencyVSAvoidcommercial competitiveness
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by creating a flexible, ongoing hybrid development program that continuously introduces new variety combinations in response to changing market and environmental conditions. Rather than relying on static, long-lived varieties, the system dynamically updates the hybrid portfolio by re-evaluating parent lines and developing new crosses that maintain reliability while adapting to current agricultural needs, thereby preserving commercial competitiveness over time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs universality by developing hybrid varieties with multi-functional trait profiles that can adapt to diverse production conditions and market demands. The inbred parent selection process targets general adaptability alongside specific yield traits, creating hybrids that can serve multiple functions across different environments and uses, thus maintaining both performance consistency and commercial competitiveness as conditions change.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If hybrid seed production requires elimination of pollen from female parent, then self-pollination is prevented, but the process complexity increases

Engineering Contradiction:
Improvehybrid purityVSAvoidseed production process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by utilizing the natural self-sterility characteristics of certain inbred parent lines, which inherently produce non-viable or absent pollen. This biological self-service mechanism eliminates the need for complex mechanical or chemical emasculation procedures, maintaining hybrid purity through the parents' own genetic properties rather than external intervention, thereby reducing process complexity while ensuring reliability.

Inventive Principle:
Principle #25Self-service

4Reliability

If treated seeds are used to enhance resistance to environmental stresses, then seedling hardiness is improved, but seed treatment cost increases

Engineering Contradiction:
Improveseedling hardinessVSAvoidseed treatment cost
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent employs parameter changes by optimizing the concentration and composition of seed treatment substances to achieve effective stress resistance at cost-effective levels. Rather than applying maximum doses of expensive treatments, the research identifies minimal effective parameters for coating formulations and application methods that provide sufficient hardiness improvement while controlling input costs, thereby balancing reliability enhancement with economic feasibility.

Inventive Principle:
Principle #35Parameter changes
