Solution Overview

Problem

Soybean breeding is complex due to self-pollination, requiring extensive intervention and genetic diversity, making the development of new soybean cultivars unpredictable and time-consuming, with existing methods being inefficient in introducing desired traits such as herbicide resistance, disease resistance, and altered fatty acid profiles.

Innovation Solution

The development of soybean cultivar BY1113023, which incorporates transgenes for herbicide resistance, disease resistance, and modified fatty acid profiles, along with methods like marker-assisted selection and backcrossing to introduce desired traits, allowing for the creation of progeny with improved yield and environmental adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional breeding methods are used, then genetic diversity is maintained, but breeding efficiency and predictability are low

Engineering Contradiction:

Improvebreeding efficiencyVSAvoidtime to develop new cultivars

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical breeding methods (manual pollination, visual selection) with molecular marker-based identification systems. DNA markers allow breeders to precisely identify and select plants with desired traits at the molecular level, dramatically accelerating the breeding process and improving predictability of trait inheritance.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces molecular markers as intermediaries between phenotypic observation and genotypic selection. These markers serve as reliable indicators that mediate the selection process, allowing breeders to identify desired traits without waiting for phenotypic expression, thereby reducing breeding time and improving efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If extensive manual intervention is applied, then cross-pollination is achieved, but breeding complexity increases

Engineering Contradiction:

Improvetrait introduction capabilityVSAvoidbreeding procedure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces complex manual breeding procedures with molecular marker-assisted selection. Instead of extensive manual intervention for cross-pollination and selection, breeders use DNA markers to identify and select plants with desired traits, simplifying the overall breeding procedure while maintaining the ability to introduce diverse traits.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If traditional selection methods are used, then natural genetic variation is utilized, but desired traits cannot be precisely introduced

Engineering Contradiction:

Improvetrait introduction precisionVSAvoidbreeding process simplicity

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent introduces molecular markers as intermediaries that enable precise identification of desired traits. These markers allow breeders to accurately select plants with specific genetic characteristics, achieving precise trait introduction while maintaining relatively simple breeding processes through marker-assisted selection.

Inventive Principle:

Principle #24Intermediary (Mediator)
