Solution Overview

Problem

The development of stable, high-yielding wheat varieties with improved grain quality and winter hardiness is a time-consuming process, requiring precise breeding and selection, and existing wheat varieties often suffer from issues like lower test weight and susceptibility to Fusarium head blight, which affects their commercial viability.

Innovation Solution

The introduction of the soft winter white wheat variety MSU Line E0028, also known as 'Ambassador,' which demonstrates higher yield, improved flour yield, and increased winter hardiness, along with methods for breeding and producing derivatives, including transgenic backcross conversions, to enhance wheat quality and resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional wheat breeding methods are used, then existing varieties can be maintained, but yield and winter hardiness are insufficient

Engineering Contradiction:
ImproveyieldVSAvoidwinter hardiness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent combines multiple desirable traits (high yield, winter hardiness, disease resistance, and improved milling quality) into a single integrated wheat variety through controlled crossing and selection processes, resolving the contradiction by merging previously separate improvement goals into one superior cultivar

Inventive Principle:
Principle #5Merging (Combining)

2Loss of time

If wheat breeding process is accelerated, then development time is reduced, but breeding precision and stability are compromised

Engineering Contradiction:
Improvebreeding development timeVSAvoidbreeding precision
Core Design Contradiction:
Loss of timeVSManufacturing precision

Solution Approach 1:

The patent employs preliminary action through pre-planned breeding objectives, selection of specific parent lines with known desirable traits, and structured multi-generation crossing programs that maintain precision while efficiently progressing toward the target variety with integrated improvements in yield, hardiness, and quality

Inventive Principle:
Principle #10Preliminary action

3Reliability

If existing wheat varieties are used, then commercial viability is maintained, but disease susceptibility and low test weight reduce profitability

Engineering Contradiction:
Improvedisease resistanceVSAvoidtest weight
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent achieves parameter changes by systematically improving multiple quantitative traits simultaneously - increasing test weight, enhancing disease resistance, and improving milling quality - through selective breeding that modifies the genetic parameters of the wheat variety to produce a superior cultivar with both higher productivity and reliability

Inventive Principle:
Principle #35Parameter changes
