Solution Overview

Problem

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

Innovation Solution

A new hybrid corn variety designated 2453832 is developed by crossing inbred varieties QAE02 and JLK02, with specific physiological and morphological characteristics, and treated seeds are used to enhance resistance to adverse conditions, incorporating seed treatment options for improved crop flexibility and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

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

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevelopment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing specific inbred lines (QAE02 and JLK02) with desirable traits before crossing them. The inbred parents were developed through prior selective breeding and evaluation to ensure they possess complementary characteristics for yield, adaptability, and stress tolerance, thereby reducing the time needed for subsequent hybrid development and selection phases

Inventive Principle:
Principle #10Preliminary action

2Productivity

If existing hybrid corn varieties are used over time, then farming operations are stable, but commercial competitiveness and yield potential decrease

Engineering Contradiction:
ImproveyieldVSAvoidcommercial competitiveness duration
Core Design Contradiction:
ProductivityVSDuration of action of stationary object

Solution Approach 1:

The patent applies parameter changes by developing hybrid variety 2453832 with modified genetic parameters that improve yield potential and adaptability. The cross between inbred lines QAE02 and JLK02 creates a new hybrid with enhanced characteristics including improved stress tolerance, disease resistance, and yield performance, thereby restoring commercial competitiveness

Inventive Principle:
Principle #35Parameter changes

3Reliability

If protective chemicals are applied to control insects, weeds and diseases, then crop protection is effective, but production costs and environmental impact increase

Engineering Contradiction:
Improvecrop protectionVSAvoidprotective chemicals
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies self-service by incorporating inherent resistance traits into hybrid corn variety 2453832 through its parental lines. The hybrid possesses genetic resistance to insects, diseases, and abiotic stresses, enabling it to protect itself without requiring extensive chemical interventions, thereby reducing both protective chemical usage and associated costs

Inventive Principle:
Principle #25Self-service
