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, KW7P1484, which includes methods for producing seeds, plants, and variants with specific morphological and physiological characteristics, utilizing techniques such as mutagenesis and tissue culture to enhance traits like yield, disease resistance, and nutritional quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional corn breeding methods are used to develop parental lines, then hybrid production can proceed, but yield and agronomic soundness are limited

Engineering Contradiction:
ImproveyieldVSAvoidstability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies mutagenesis techniques to induce genetic variations and changes in the corn inbred line, creating new phenotypic parameters that improve yield potential while maintaining agronomic stability through selective breeding

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If existing inbred lines are used for hybrid production, then breeding programs can continue, but superior parental lines with enhanced traits are not achieved

Engineering Contradiction:
Improveagronomic traitsVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent performs preliminary mutagenesis and selection to pre-develop inbred lines with enhanced agronomic traits before they are used in hybrid breeding programs, thereby reducing the complexity of subsequent breeding operations and improving overall program efficiency

Inventive Principle:
Principle #10Preliminary action
