Solution Overview

Problem

The development of new wheat varieties is a time-consuming process requiring significant technical human intervention and precise planning, involving multiple steps and resources, to combine desirable traits such as higher seed yield, disease resistance, and adaptability, which can take six to twelve years from the initial cross.

Innovation Solution

The wheat variety 25R72, developed through a modified pedigree selection method, combines improved traits like disease resistance, yield potential, and adaptability, achieved by cross-pollination techniques, molecular marker use, and backcross conversion, resulting in a stable and homogeneous wheat line suitable for various agricultural conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional wheat breeding methods are used to combine desirable traits, then the resulting variety has improved agronomic characteristics and disease resistance, but the development process takes six to twelve years and requires significant technical human intervention

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Molecular markers are used to identify and select plants with desirable traits at early stages of breeding, allowing breeders to make informed decisions before completing the full breeding cycle. This preliminary identification accelerates the selection process and reduces the overall development time while maintaining disease resistance traits

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If multiple breeding steps and cross-pollination techniques are applied to achieve stable and homogeneous wheat lines, then the variety shows consistent performance and adaptability, but the process requires significant technical human intervention and resources

Engineering Contradiction:
Improvevariety uniformityVSAvoidbreeding process complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

Molecular markers provide continuous feedback during the breeding process, allowing breeders to monitor the presence and combination of desirable traits in real-time. This feedback mechanism enables more efficient selection decisions and reduces the number of breeding cycles needed to achieve stable, homogeneous lines, thereby simplifying the overall process complexity
