Solution Overview

Problem

Current wheat breeding methods face challenges in combining desirable traits such as high seed yield, disease resistance, drought tolerance, and improved nutritional quality in a single wheat cultivar, while also maintaining stability across different environments and generations.

Innovation Solution

The development of the wheat cultivar H4N12-0058, which involves a combination of traditional breeding techniques and genetic transformation to introduce specific traits like herbicide resistance, disease resistance, and improved nutritional quality, along with methods for producing hybrid seeds and using tissue culture for regenerable cells to express morphological and physiological characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If traditional breeding techniques are used to combine multiple desirable traits, then the complexity of the breeding program increases, but the ability to successfully combine all desired traits in a single cultivar decreases

Engineering Contradiction:

Improvebreeding program complexityVSAvoidtrait combination success

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent combines multiple desirable traits (herbicide resistance, disease resistance, drought tolerance, nutritional quality) into a single wheat cultivar H4N12-0058 through systematic breeding programs that merge parental germplasm with complementary traits, achieving reliable trait combination despite program complexity

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If multiple traits are combined in a single cultivar, then the agronomic quality improves, but the stability of the cultivar across different environments becomes more difficult to maintain

Engineering Contradiction:

Improveagronomic qualityVSAvoidcultivar stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent evaluates and optimizes multiple parameters simultaneously in cultivar H4N12-0058, including yield, protein content, disease resistance levels, and stress tolerance, achieving both high agronomic quality and environmental stability through balanced parameter selection

Inventive Principle:

Principle #35Parameter changes

3Manufacturing precision

If genetic transformation is used to introduce specific traits, then the precision of trait introduction improves, but the complexity of the development process increases

Engineering Contradiction:

Improvetrait introduction precisionVSAvoiddevelopment process complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent employs genetic transformation techniques to replace traditional mechanical cross-breeding methods, enabling precise introduction of specific traits (such as herbicide resistance and disease resistance) into the wheat cultivar without the uncertainty of genetic recombination in conventional crossing

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
