Solution Overview

Problem

The development of new maize varieties is a time-consuming process that takes six to twelve years, and there is a continuous need for stable, high-yielding maize varieties with improved traits such as disease resistance, drought tolerance, and better agronomic characteristics.

Innovation Solution

A novel maize variety, PH48CS, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and drought tolerance, achieved through backcross conversion, genetic manipulation, and transformation, allowing for the creation of hybrid maize seeds with enhanced agronomic properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maize breeding processes are used to develop new varieties with improved traits, then disease resistance and yield stability are improved, but the development time increases significantly (6-12 years)

Engineering Contradiction:
Improveyield stabilityVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-establishing a standardized inbred line PH48CS with optimized genetic characteristics including disease resistance and yield stability. This pre-developed genetic foundation allows breeders to skip lengthy traditional breeding steps and directly create hybrids by crossing with other inbreds, dramatically reducing development time while maintaining reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by modifying specific genetic parameters through backcross conversion and genetic manipulation to create PH48CS with enhanced traits. By changing key genetic parameters such as disease resistance genes and yield-related characteristics, the patent achieves improved reliability without requiring the full 6-12 year traditional breeding cycle

Inventive Principle:
Principle #35Parameter changes

2Productivity

If multiple desirable traits are combined in a single maize variety through traditional breeding, then agronomic characteristics and yield are improved, but the breeding process complexity and time consumption increase

Engineering Contradiction:
Improvemaize yieldVSAvoidbreeding process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies merging by consolidating multiple desirable traits including disease resistance, drought tolerance, and high yield potential into a single standardized inbred line PH48CS. This consolidation allows breeders to combine PH48CS with other inbreds to create hybrids that inherit these pre-combined traits, simplifying the breeding process while maintaining high productivity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements universality by creating PH48CS as a multi-functional inbred line that can serve multiple purposes: as a parent for hybrid development, as a source of disease resistance, and as a contributor to yield stability. This universal inbred line can be crossed with various other inbreds to produce different hybrid varieties, reducing breeding process complexity while achieving high productivity across multiple applications

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