Innovation Solution

The introduction of the inbred corn line D086586, which is a new yellow dent inbred corn line with specific physiological and morphological characteristics, and methods for producing and utilizing it, including self-pollination, sib-pollination, and hybrid production, as well as genetic modification and tissue culture techniques to enhance its traits and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If traditional inbreeding techniques are used to develop new inbred corn lines, then genetic uniformity and purity are improved, but the development process becomes slow and costly

Engineering Contradiction:
Improvegenetic uniformityVSAvoiddevelopment time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by establishing a structured multi-generation inbreeding program that prepares and maintains inbred lines through systematic self-pollination and selection procedures. The method pre-establishes protocols for maintaining genetic purity through controlled pollination and selection, allowing breeders to efficiently develop new inbred lines without ad-hoc delays.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies parameter changes by modifying breeding parameters such as generation intervals, selection intensity, and pollination control methods. The method optimizes these parameters to accelerate the inbreeding process while maintaining genetic uniformity, transforming the traditionally slow process into a more efficient system.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If existing inbred parent corn lines are used repeatedly, then breeding efficiency is maintained, but commercial competitiveness is lost over time

Engineering Contradiction:
Improvebreeding efficiencyVSAvoidcommercial competitiveness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies dynamics by creating a flexible inbred line development system that can adapt to changing market demands and genetic resources. The method enables breeders to dynamically introduce new genetic material, adjust breeding strategies, and refresh inbred line portfolios to maintain commercial competitiveness while preserving breeding efficiency.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies discarding and recovering by systematically evaluating and phasing out outdated inbred lines while recovering and incorporating new genetic resources. The method establishes protocols for assessing the commercial value of existing lines and replacing them with improved lines, ensuring the breeding program remains competitive.

Inventive Principle:
Principle #34Discarding and recovering

3Stability of the object's composition

If self-pollination and sib-pollination techniques are applied, then inbred line purity is improved, but the process requires extensive manual intervention and isolation

Engineering Contradiction:
Improveinbred line purityVSAvoidbreeding system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding population into distinct isolation groups and organizing pollination events into separate, controlled stages. The method segments the breeding process into discrete steps with clear isolation protocols, making the complex manual intervention requirements more manageable and systematic.

Inventive Principle:
Principle #1Segmentation
