Solution Overview

Problem

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

Innovation Solution

A new yellow dent hybrid corn variety, designated 1374689, is developed through a three-way cross of inbred parents 11084BM, BE1146BM, and LLD06BM, with specific physiological and morphological characteristics, and treated seeds are used to enhance resistance to adverse conditions, incorporating seed treatments like sodium methylphenyl-pentadienate and polyoxyalkylene-organo-siloxane block copolymer to improve plant hardiness.

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:
Improvecorn yieldVSAvoidbreeding development time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing specific inbred lines (11084BM, BE1146BM, LLD06BM) with desirable traits before hybridization. The inbred parents were developed and evaluated in advance, allowing the hybrid variety 1374689 to inherit predetermined beneficial characteristics that immediately improve yield without requiring additional breeding time.

Inventive Principle:
Principle #10Preliminary action

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:
ReliabilityVSProductivity

Solution Approach 1:

The patent applies parameter changes by creating a new hybrid variety with modified genetic parameters through the specific cross of three inbred lines. This generates novel trait combinations that change key performance parameters such as yield potential, stress resistance, and adaptability, thereby restoring commercial competitiveness while maintaining reliability through controlled breeding.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If protective chemicals are applied to control pests and diseases, then plant health is improved, but production costs and environmental impact increase

Engineering Contradiction:
Improveplant healthVSAvoidprotective chemicals usage
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies self-service by developing hybrid corn variety 1374689 with inherent resistance traits to insects, weeds, and diseases through its genetic composition from specific inbred parents. The plant's own genetic makeup provides protection against pests and diseases, reducing or eliminating the need for external protective chemicals while maintaining plant health.

Inventive Principle:
Principle #25Self-service
