Solution Overview

Problem

The development of new corn inbred lines is a time-consuming and unpredictable process due to the complexity of inheritance and environmental factors, making it challenging to identify genetically superior plants with desirable traits such as high yield, disease resistance, and adaptability.

Innovation Solution

The introduction of the inbred corn line ML9, which is a yellow dent corn with superior characteristics, adapted to specific maturity zones in the US Corn Belt, and methods for producing hybrid seeds and plants with traits like male sterility, herbicide resistance, and improved nutritional quality through genetic modification and backcrossing techniques.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional breeding methods are used to develop new corn inbred lines, then genetic diversity and adaptability are improved, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:
ImproveadaptabilityVSAvoidbreeding time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing specific inbred lines (such as ML9) with known superior traits including yield potential, adaptability to multiple maturity zones, and resistance to diseases and insects. This pre-characterization allows breeders to immediately use these lines in hybrid development without lengthy evaluation periods, significantly reducing the time required while maintaining high adaptability.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If extensive testing and evaluation of breeding lines is conducted to ensure superior traits, then reliability of the inbred line is improved, but the complexity of the breeding program increases

Engineering Contradiction:
ImprovereliabilityVSAvoidbreeding program complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct modules: (1) development and characterization of individual inbred lines with specific traits, (2) evaluation of hybrid combinations, and (3) regional adaptation testing. This modular approach allows each component to be optimized independently and reduces overall program complexity while ensuring reliable selection of superior inbred lines through systematic, stepwise evaluation.

Inventive Principle:
Principle #1Segmentation
