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 the need for innovative approaches to combine desirable traits effectively.

Innovation Solution

The development of the soybean variety A1026349, which involves specific breeding techniques like backcrossing and genetic transformation to introduce desired traits like herbicide resistance, disease resistance, and improved nutritional quality, along with methods for tissue culture and regeneration to produce plants expressing these 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 outcomesVSAvoidbreeding cycle duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by using pre-developed germplasm lines with known desirable traits (disease resistance, drought tolerance, high yield) as starting materials. The breeding program begins with selection of germplasm that already possesses target traits, rather than discovering them during the breeding process, thereby reducing time and increasing predictability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by transitioning from conventional phenotypic selection to marker-assisted selection, where molecular markers are used to track and select for specific genetic loci. This changes the parameter of selection from observable traits to genetic markers, enabling more precise and predictable breeding outcomes with reduced time.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If conventional breeding techniques are used, then soybean varieties can be developed, but the process is complex and inefficient

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

Solution Approach 1:

The patent applies segmentation by dividing the breeding program into distinct modules: germplasm selection, crossing design, marker-assisted selection, and evaluation. Each module handles specific aspects of trait combination, making the overall complex process more manageable and efficient through systematic organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses molecular markers as intermediaries between the breeding objectives and the actual selection process. These markers serve as mediators that link desired traits to selectable genetic markers, simplifying the breeding process by providing direct genetic indicators rather than requiring complex phenotypic evaluations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple desirable traits are combined in a single variety, then agronomic quality improves, but the breeding difficulty increases

Engineering Contradiction:
Improveagronomic qualityVSAvoidbreeding difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies merging by integrating multiple desirable traits (disease resistance, drought tolerance, high yield, improved compositional traits) into a single variety through coordinated germplasm selection and strategic crossing. The program combines these traits by selecting parent lines that carry different desirable traits and systematically combining them in offspring.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent utilizes universality by developing germplasm lines that possess multiple desirable traits simultaneously, creating multi-functional parent lines that can contribute various traits to offspring. This reduces the number of separate breeding operations needed, as each parent line serves multiple purposes in trait combination.

Inventive Principle:
Principle #6Universality (Multi-functionality)
