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 creating stable, high-yielding maize varieties with desirable traits such as disease resistance, drought tolerance, and improved agronomic characteristics.

Innovation Solution

A novel maize variety, 1PLPF77, 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 to develop new varieties with desirable traits, then the varieties achieve stability and high yield, but the development process takes 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 line 1PLPF77 with specific desirable traits (disease resistance, drought tolerance, yield stability) before hybrid development. This preliminary characterization and selection of parent lines with complementary traits accelerates the breeding process by 3-5 years while maintaining yield stability, as the parent lines are already optimized for specific functions rather than requiring extensive field testing during hybrid development

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple desirable traits are combined in a single maize variety, then the variety achieves greater yield and stress tolerance, but the breeding process becomes more complex and time-consuming

Engineering Contradiction:
Improvestress toleranceVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the complex multi-trait breeding process into separate functional components: inbred line 1PLPF77 provides disease resistance and drought tolerance traits, while complementary inbred lines contribute yield and maturity traits. This modular approach allows parallel development of trait-specific parent lines, reducing overall breeding complexity and time while achieving cumulative trait benefits in the final hybrid

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies universality by developing inbred line 1PLPF77 with multiple stress tolerance traits (disease resistance, drought tolerance, heat tolerance) that can be universally applied across different hybrid combinations and environmental conditions. This multi-functional parent line serves as a versatile foundation for creating various hybrid varieties targeting different market needs, reducing the need for separate breeding programs for each trait combination

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