Solution Overview

Problem

There is a need for stable, high-yielding corn hybrids that are agronomically sound to maximize ear or kernel production, addressing the challenge of developing superior parental lines for corn breeding.

Innovation Solution

The development of a novel inbred corn line designated BV10, which includes methods for producing seeds, plants, and variants thereof, utilizing mutagenesis techniques and transgenic approaches to introduce desired traits such as herbicide resistance, disease resistance, and improved nutritional quality, while maintaining the physiological and morphological characteristics of the original line.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional breeding methods are used to develop corn hybrids, then the parental lines can be selected, but the yield and agronomic performance are limited

Engineering Contradiction:
Improvekernel productionVSAvoidhybrid stability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies mutagenesis techniques to induce genetic variations in corn plants, changing the genetic parameters to achieve superior yield and agronomic performance. This allows breeders to create new variants with improved traits while maintaining hybrid stability through controlled mutation and selection processes.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If mutagenesis techniques are applied to introduce desired traits, then traits like herbicide resistance and disease resistance are improved, but the complexity of the breeding process increases

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs self-service principles by allowing the mutagenized plants to express their traits naturally and be selected based on their performance. The breeding process leverages natural selection and plant self-expression of mutated traits, reducing the need for complex external interventions while achieving reliable disease and herbicide resistance.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple mutagenesis methods are used to generate variants, then the diversity of traits is increased, but the time and resources required for screening and selection increase

Engineering Contradiction:
Improvetrait diversityVSAvoidscreening time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by conducting mutagenesis treatments early in the breeding process to generate diverse variants before extensive screening is needed. This allows the creation of a broad genetic base with varied traits upfront, making subsequent selection more efficient and reducing the overall time required for developing improved corn hybrids.

Inventive Principle:
Principle #10Preliminary action
