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 efficient trait introduction and environmental adaptability.

Innovation Solution

The development of soybean cultivar AR1211948 and methods involving transgenes for herbicide resistance, fungal resistance, insect resistance, and altered oil profiles, combined with breeding techniques like marker-assisted selection and backcrossing to introduce desired traits, enabling the creation of stable and high-yielding soybean lines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

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

Engineering Contradiction:
Improvegenetic diversityVSAvoidbreeding development time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs molecular markers as intermediary tools to track and select desired alleles during breeding. These markers serve as mediators between the breeder and the genetic traits, enabling precise identification and selection of plants carrying target genes without requiring extensive phenotypic evaluation across multiple generations, thus significantly reducing breeding time while maintaining genetic diversity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If extensive manual intervention is applied to pollination for trait breeding, then desired traits can be introduced, but the breeding process complexity increases

Engineering Contradiction:
Improvetrait introduction capabilityVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical pollination intervention with molecular marker-assisted selection systems. Instead of physically manipulating pollination processes and visually tracking traits through generations, the system uses DNA markers to automatically identify and select plants with desired alleles, substituting mechanical breeding operations with molecular detection methods that reduce procedural complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Manufacturing precision

If marker-assisted breeding is used to move desired alleles accurately, then breeding precision is improved, but the requirement for intensive research and development increases

Engineering Contradiction:
Improveallele movement precisionVSAvoidresearch and development intensity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-developing and storing a comprehensive library of molecular markers associated with various soybean traits before actual breeding begins. This preparatory work includes characterizing markers, establishing their inheritance patterns, and creating reference databases, which enables rapid and precise allele tracking during subsequent breeding operations without requiring intensive R&D during the actual breeding process

Inventive Principle:
Principle #10Preliminary action
