Solution Overview

Problem

Current soybean breeding methods face challenges in developing stable, high-yielding soybean varieties with desirable traits such as disease resistance, drought tolerance, and improved nutritional quality, as they rely on conventional breeding techniques that are time-consuming and unpredictable, leading to difficulties in identifying genetically superior plants amidst environmental and genetic variability.

Innovation Solution

The development of the soybean variety A1035502, which combines improved traits through a breeding program involving crossing, selection, and genetic transformation, utilizing techniques like backcrossing and marker-assisted selection to introduce desired loci, resulting in a variety with enhanced resistance to diseases, insects, and improved agronomic characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

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

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

Solution Approach 1:

The patent replaces conventional mechanical breeding methods (crossing, selection, and breeding) with genetic engineering techniques (gene cloning, transformation, and molecular markers) to achieve predictable introduction of desirable traits without the time-consuming nature of traditional breeding

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

Solution Approach 2:

The patent uses molecular markers and selective breeding programs as intermediaries to identify and propagate desirable traits more efficiently, allowing breeders to track specific genes through generations and make informed selection decisions rather than relying on phenotypic observation alone

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If conventional breeding techniques are used, then soybean varieties can be developed, but it is difficult to identify genetically superior plants amidst environmental and genetic variability

Engineering Contradiction:
Improveidentification accuracy of superior plantsVSAvoidbreeding program complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces phenotypic selection with genotypic selection using molecular markers and DNA analysis, enabling precise identification of plants carrying desired genes regardless of environmental influences on physical traits

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

Solution Approach 2:

The patent implements selective breeding programs that use molecular marker data to provide feedback on genetic composition, allowing breeders to make informed decisions about which plants to propagate based on actual genetic content rather than environmental expression

Inventive Principle:
Principle #23Feedback
