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 combining desirable traits such as disease resistance, drought tolerance, and high yield in a single variety that is agronomically sound across different conditions and environments.

Innovation Solution

A novel maize variety, 6CWXI1550, 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 stable, high-yielding hybrids with improved agronomic characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maize breeding methods are used to combine desirable traits, then disease resistance and drought tolerance can be achieved, but the development process takes six to twelve years

Engineering Contradiction:
Improvedisease resistanceVSAvoiddevelopment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs preliminary action by using molecular markers to identify and select plants with desired traits early in the breeding process. This allows breeders to predict which plants will inherit disease resistance and drought tolerance before actual phenotypic expression occurs, significantly reducing the time required for trait verification and variety development.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms through molecular marker-assisted selection, where genetic information is continuously monitored and used to guide breeding decisions. This feedback loop enables real-time selection of plants carrying desired alleles, accelerating the breeding process while maintaining reliability of trait inheritance.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If multiple desirable traits are combined in a single variety, then agronomic soundness and yield stability improve, but the breeding process becomes more complex

Engineering Contradiction:
Improveagronomic soundnessVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by breaking down the complex breeding process into manageable components. Molecular markers are used to track individual genes and trait combinations separately, allowing breeders to systematically assemble multiple desirable traits through controlled crosses and selection, thereby reducing overall process complexity while achieving multi-trait varieties.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs universality through the use of molecular markers that can detect multiple different traits simultaneously. This multi-functional approach allows a single breeding program to track and select for disease resistance, drought tolerance, and other desirable traits using the same molecular toolkit, simplifying the management of complex multi-trait breeding programs.

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