Solution Overview

Problem

The development of new maize varieties and hybrids is a time-consuming process, requiring six to twelve years from the first cross to delivering finished seed to farmers, and existing technologies struggle to combine desirable traits such as disease resistance, drought tolerance, and high yield in a stable and agronomically sound manner.

Innovation Solution

A novel maize variety, PH47MY, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and drought tolerance via backcross conversion, genetic manipulation, and transformation, allowing for the creation of hybrid seeds with enhanced agronomic characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional maize breeding methods are used to combine desirable traits, then the resulting variety has improved agronomic characteristics, but the development process takes six to twelve years

Engineering Contradiction:
Improveagronomic soundnessVSAvoidbreeding 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 combining them. The inbred PH47MY is developed with predetermined characteristics that can be systematically combined with other pre-characterized inbreds, reducing the trial-and-error time of traditional breeding while maintaining agronomic soundness through planned crosses rather than random selection

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple desirable traits are combined in a single variety, then the variety has maximal yield over different conditions, but the breeding process becomes more complex

Engineering Contradiction:
Improveyield stability across environmentsVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the complex task of creating multi-traditional varieties into manageable components by developing distinct inbred lines, each optimized for specific traits (e.g., PH47MY for disease resistance and drought tolerance). This segmentation allows breeders to work with standardized, pre-characterized genetic building blocks rather than attempting to combine all traits simultaneously, reducing breeding process complexity while achieving yield stability across environments through strategic combinations of segmented inbred lines

Inventive Principle:
Principle #1Segmentation
