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, 6DDMX1102, 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 seeds with enhanced agronomic properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maize breeding methods are used, then stable high-yielding varieties can be developed, but the development process takes six to twelve years which is time-consuming

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

Solution Approach 1:

The patent applies preliminary action by developing and maintaining a pre-characterized inbred maize line (6DDMX1102) with known desirable traits including disease resistance, drought tolerance, and agronomic characteristics. This pre-developed genetic foundation allows breeders to skip lengthy breeding steps and directly utilize the inbred line for hybrid production, significantly reducing the 6-12 year development timeline while maintaining yield stability and reliability

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple desirable traits are combined in a single variety, then agronomic performance and resistance are improved, but the breeding process becomes more complex

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple desirable traits into a single integrated inbred maize line (6DDMX1102), combining disease resistance, drought tolerance, and superior agronomic characteristics. This consolidation approach simplifies the breeding process by providing a ready-made genetic package that breeders can directly utilize, eliminating the need to separately develop and combine multiple trait lines, thus reducing breeding complexity while maintaining high adaptability

Inventive Principle:
Principle #5Merging (Combining)
