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 needing improvement for traits like herbicide resistance, disease resistance, and yield enhancement.

Innovation Solution

The development of soybean cultivar BN1012650, which incorporates transgenes for herbicide resistance, disease resistance, and altered oil profiles, using techniques such as marker-assisted selection and transformation to enhance genetic traits, along with breeding methods like backcrossing and pedigree breeding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional breeding methods are used for soybean cultivar development, then genetic diversity is maintained through self-pollination, but the breeding process becomes highly unpredictable and time-consuming

Engineering Contradiction:

Improvepredictability of breeding outcomesVSAvoidbreeding development time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Molecular markers serve as intermediary tools that allow breeders to indirectly select for desired traits without waiting for phenotypic expression. By using DNA markers linked to target genes, the breeding process becomes predictable and can be accelerated, resolving the contradiction between reliability and time loss in traditional breeding methods

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical/visual selection methods with molecular marker-assisted selection. Instead of relying on phenotypic observation and manual selection over multiple generations, breeders use molecular techniques to directly identify and select plants with desired genetic traits, dramatically reducing breeding time and improving predictability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If extensive genetic diversity is maintained through self-pollination, then trait selection becomes more complex, but breeding intervention requirements increase

Engineering Contradiction:

Improvegenetic diversityVSAvoidbreeding method complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Molecular markers act as intermediaries that simplify the complexity of selecting from diverse genetic material. By providing direct molecular evidence of desired traits, markers reduce the complexity of breeding interventions needed to manage genetic diversity and select for specific traits

Inventive Principle:

Principle #24Intermediary (Mediator)

3Manufacturing precision

If marker-assisted selection and transformation techniques are used to enhance genetic traits, then breeding precision is improved, but method complexity increases

Engineering Contradiction:

Improvebreeding selection precisionVSAvoidbreeding technique complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent replaces imprecise phenotypic selection with precise molecular marker-assisted selection. This substitution dramatically improves breeding precision by allowing direct detection of desired genetic traits at the DNA level, even though it introduces more complex molecular techniques into the breeding process

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
