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 across various conditions and environments.

Innovation Solution

A novel maize variety, 1PKGP36, 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 yield and adaptability.

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:
Improvestability of maize varietyVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-selecting and characterizing inbred line 1PKGP36 with specific desirable traits (disease resistance, drought tolerance, yield potential) before hybrid development. This preliminary characterization and selection of parent lines with complementary traits accelerates the breeding process by reducing the need for extensive multi-year field testing and selection cycles that would otherwise be required to identify suitable parent combinations.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If maize breeders select for multiple desirable traits including disease resistance, drought tolerance, and yield, then the resulting variety is agronomically sound, but the selection process becomes increasingly complex and time-consuming

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

Solution Approach 1:

The patent applies segmentation by dividing the complex breeding program into distinct modular components: (1) development and characterization of inbred line 1PKGP36 with specific trait combinations, (2) identification of complementary parent lines, (3) systematic hybrid development and testing. This segmentation allows each component to be optimized independently and facilitates the integration of multiple desirable traits without overwhelming program complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies parameter changes by systematically evaluating and selecting parent lines based on specific measurable parameters including disease resistance levels, drought tolerance indices, yield components, and maturity characteristics. By defining and optimizing these key parameters for inbred line 1PKGP36 and its hybrid counterparts, the breeding program achieves agronomic adaptability through quantitative trait selection rather than qualitative trial-and-error approaches.
