Solution Overview

Problem

The development of new maize varieties and hybrids is a time-consuming process, taking six to twelve years, and existing technologies face challenges in creating stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved agronomic characteristics.

Innovation Solution

The introduction of the novel maize variety 1PEEA63, which involves specific breeding techniques including backcross conversion, genetic manipulation, and transformation to incorporate traits like male sterility, disease resistance, and improved metabolic traits, along with detailed processes for crossing and seed production to ensure uniformity and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maize breeding methods are used to develop new varieties with desirable traits, then the varieties achieve stability and high yield, but the development process takes six to twelve years

Engineering Contradiction:
Improvevariety stabilityVSAvoiddevelopment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing inbred line 1PEEA63 with specific desirable traits (disease resistance, drought tolerance, yield potential) before hybrid development. This preliminary characterization allows breeders to immediately use the inbred line in hybrid combinations without extensive preliminary testing, thereby reducing the overall development time while maintaining variety stability and high yield characteristics

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple desirable traits are combined in a single maize variety, then the variety achieves greater adaptability and yield, but the breeding process becomes more complex and time-consuming

Engineering Contradiction:
Improveenvironmental adaptabilityVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple desirable traits into inbred line 1PEEA63 through systematic breeding, combining disease resistance, drought tolerance, and yield potential into a single genetic platform. This consolidation allows the trait package to be efficiently transferred to hybrid varieties through crossing, reducing breeding process complexity compared to developing each trait separately in different lines

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Inbred line 1PEEA63 serves as a universal parent line that can be crossed with multiple different inbred lines to produce various hybrid combinations, all inheriting its desirable traits. This multi-functionality allows the same inbred line to contribute to multiple hybrid varieties with different adaptability characteristics, simplifying the breeding process while maintaining high adaptability across different environmental conditions

Inventive Principle:
Principle #6Universality (Multi-functionality)
