Solution Overview

Problem

The development of new maize varieties and hybrids is a time-consuming process that takes around six to twelve years, and there is a continuous need for stable, high-yielding maize varieties that are agronomically sound and can perform well under various conditions and environments.

Innovation Solution

A novel maize variety, designated 1PCBD43, and processes for making it are provided. This variety can be used to produce seed, plants, and plant parts with specific traits introduced through backcross conversion, genetic manipulation, and transformation. The variety can also include cytoplasmic or nuclear factors for male sterility, and it can be used to produce hybrid maize seeds and plants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maize breeding processes are used to develop new varieties, then stable and agronomically sound varieties can be achieved, but the development time becomes excessively long (6-12 years)

Engineering Contradiction:
Improvestability and agronomic soundness of maize varietyVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-characterizing the inbred maize line 1PCBD43 with multiple desirable traits (disease resistance, yield potential, agronomic characteristics) before hybrid development. This advance preparation and selection of a well-characterized base line accelerates the breeding process while ensuring reliability, as the foundational genetic material has already been optimized for stability and performance across multiple traits

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If traditional breeding methods are used, then maize varieties with multiple desirable traits can be developed, but the process becomes extremely time-consuming

Engineering Contradiction:
Improvenumber of desirable traits in maize varietyVSAvoidbreeding development time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent merges multiple desirable traits into a single inbred maize line (1PCBD43) through systematic breeding and selection. This consolidation of traits (disease resistance, yield, agronomic characteristics) into one foundational line allows for accelerated hybrid development, as the pre-combined trait package can be rapidly deployed across multiple hybrid combinations without repeating the trait accumulation process

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If new maize varieties are developed rapidly, then time constraints are addressed, but achieving stable and high-yielding varieties with maximal agronomic performance becomes difficult

Engineering Contradiction:
Improvebreeding development speedVSAvoidyield stability and agronomic performance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The inbred maize line 1PCBD43 exhibits self-service characteristics through its inherent genetic stability and consistent performance across environments. The line's well-established genetic foundation for disease resistance, yield, and agronomic traits allows it to reliably contribute to hybrid performance without requiring extensive additional testing or stabilization, thereby enabling rapid development while maintaining reliability

Inventive Principle:
Principle #25Self-service
