Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved agronomic qualities, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to genetic variability and environmental dependence.

Innovation Solution

The development of the soybean variety A1026256, which is adapted for early group 3 growing regions, involves specific breeding techniques including bulk and single plant selection, and can be used for crossing with other plants to produce hybrid seeds and plants with desired traits like herbicide resistance and disease resistance, utilizing genetic transformation and marker-assisted selection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional breeding techniques are used, then soybean varieties can be developed with desirable traits, but the process is time-consuming and unpredictable

Engineering Contradiction:
Improvepredictability of breeding outcomesVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces conventional mechanical breeding methods (cross-pollination, selection, and breeding) with genetic engineering techniques (genetic transformation, marker-assisted selection) to directly introduce desirable traits into soybean varieties, thereby reducing the time and increasing the predictability of breeding outcomes

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

Solution Approach 2:

The patent uses molecular markers as intermediaries to identify and select plants with desired traits during the breeding process, enabling more precise and predictable trait inheritance without relying on time-consuming conventional selection methods

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If conventional breeding techniques are used, then soybean varieties can be developed, but genetic variability and environmental dependence increase

Engineering Contradiction:
Improvegenetic stability of soybean varietyVSAvoidenvironmental adaptability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent introduces specific desirable traits (herbicide resistance, disease resistance) at localized genetic positions through targeted genetic transformation, rather than relying on broad genetic variability from conventional breeding, thus achieving genetic stability while maintaining environmental adaptability through precise trait introduction

Inventive Principle:
Principle #3Local quality

3Productivity

If genetic transformation and marker-assisted selection are used, then breeding efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvebreeding program efficiencyVSAvoidbreeding technique complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces complex, time-consuming conventional breeding procedures with more efficient genetic transformation and marker-assisted selection techniques, where molecular markers serve as simplified indicators for trait presence, reducing the overall complexity of the breeding program despite the introduction of biotechnological tools

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