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, PH41JM, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and improved agronomic characteristics, using backcross conversion, genetic manipulation, and transformation techniques, allowing for the creation of hybrid maize seeds with enhanced properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maize breeding methods are used to develop new varieties with improved traits, then the desired traits (disease resistance, drought tolerance, yield) are achieved, but the development time becomes excessively long (six to twelve years)

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

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing inbred lines with specific desirable traits (disease resistance, drought tolerance, yield potential) before hybridization. The inbred PH41JM has been pre-developed through systematic breeding to possess multiple desirable traits simultaneously, so that when crossed with other inbreds, the hybrid inherits these pre-selected characteristics, significantly reducing the time required for variety development while maintaining reliability.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple desirable traits are combined in a single maize variety through traditional breeding, then the variety becomes more complex and adaptable, but the breeding process becomes more difficult and time-consuming

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

Solution Approach 1:

The patent applies segmentation by dividing the complex breeding process into distinct stages: first developing individual inbred lines with specific traits (PH41JM was developed to carry multiple traits), then combining these pre-characterized inbreds through controlled crosses. This segmentation allows each inbred to be optimized for specific functions, and the final hybrid inherits a组合 of traits without requiring the breeder to manage all trait combinations simultaneously, thus reducing breeding process complexity while maintaining high adaptability.

Inventive Principle:
Principle #1Segmentation
