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 nutritional quality, 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 A1024319, which combines improved traits through specific breeding methods including backcrossing and genetic transformation, allowing for the introduction of desired loci such as herbicide resistance, disease resistance, and nutritional enhancements, while maintaining the morphological and physiological characteristics of the original variety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional breeding techniques are used, then genetic diversity is maintained, but breeding time is excessive and yield stability is poor

Engineering Contradiction:
Improvebreeding efficiencyVSAvoidbreeding time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies parameter changes by modifying genetic parameters through molecular marker-assisted selection and backcrossing. This allows precise control over genetic traits, significantly reducing the time required to develop new soybean varieties while maintaining genetic diversity. The use of DNA markers enables selection at the molecular level rather than waiting for phenotypic expression, accelerating the breeding process.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs copying by using molecular markers to copy and track specific genetic traits through generations. DNA markers serve as copies or indicators of desired genetic traits, allowing breeders to select plants carrying specific traits without having to wait for the traits to manifest phenotypically, thus reducing breeding time while maintaining genetic diversity.

Inventive Principle:
Principle #26Copying

2Stability of the object's composition

If conventional breeding techniques are used, then natural genetic variation is preserved, but variety stability is poor

Engineering Contradiction:
Improvevariety stabilityVSAvoidbreeding efficiency
Core Design Contradiction:
Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent replaces mechanical/phenotypic selection systems with molecular marker-based selection. Instead of visually selecting plants based on observable traits, the invention uses DNA markers to detect and select for desired genetic traits at the molecular level. This substitution provides greater precision and stability in variety composition while maintaining breeding efficiency.

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

Solution Approach 2:

The patent implements feedback through molecular marker-assisted selection, where genetic information is continuously monitored and used to guide breeding decisions. DNA markers provide real-time feedback on the genetic composition of breeding populations, allowing for precise control over trait inheritance and variety stability across generations.

Inventive Principle:
Principle #23Feedback

3Reliability

If backcrossing and transformation techniques are applied, then desired traits are introduced, but genetic uniformity increases

Engineering Contradiction:
Improvetrait consistencyVSAvoidgenetic diversity
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by introducing specific desired traits into an existing genetic background through backcrossing. The molecular markers enable precise identification and selection of plants that have acquired the desired trait while retaining the majority of the original variety's genetic composition. This allows for localized genetic modification without compromising overall genetic diversity.

Inventive Principle:
Principle #3Local quality
