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 stable and agronomically sound manner.

Innovation Solution

The introduction of the novel maize variety PH2TS3, which involves crossing with another maize plant to introduce traits like male sterility, disease resistance, and improved agronomic characteristics through backcross conversion, genetic manipulation, and transformation, along with specific breeding processes to produce hybrid maize seeds and plants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

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

Engineering Contradiction:
Improvestability of varietyVSAvoidbreeding time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs preliminary action by pre-selecting and characterizing inbred lines with specific desirable traits (disease resistance, drought tolerance, yield potential) before combining them. The inbred PH2TS3 has been pre-developed with stable genetic characteristics through prior breeding work, allowing faster hybrid development without sacrificing stability. This preliminary characterization of parental lines accelerates the overall breeding timeline while maintaining variety reliability.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple desirable traits are combined in a single variety, then agronomic performance is improved, but the complexity of the breeding program increases

Engineering Contradiction:
Improveagronomic performanceVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct modular components: developing inbred lines with specific traits (disease resistance, drought tolerance, yield), characterizing their genetic makeup, and then combining them in controlled hybridizations. Each inbred line serves as a self-contained module with defined characteristics, making the overall breeding program more manageable and less complex while achieving multiple desirable traits in the final hybrid variety.

Inventive Principle:
Principle #1Segmentation

3Productivity

If rapid breeding methods are used to reduce development time, then breeding efficiency increases, but the stability and agronomic soundness of the variety may be compromised

Engineering Contradiction:
Improvebreeding efficiencyVSAvoidagronomic soundness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms through rigorous evaluation and characterization of inbred lines at multiple stages. Genetic markers are used to verify trait inheritance, and agronomic performance is assessed under controlled conditions before advancing to hybrid development. This feedback loop ensures that rapid breeding methods do not compromise variety stability or agronomic soundness, as only lines meeting predefined criteria proceed to the next breeding stage.

Inventive Principle:
Principle #23Feedback
