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 the need for innovative approaches to introduce specific desirable characteristics.

Innovation Solution

The development of the soybean variety A1026807, which includes methods for crossing and breeding techniques like backcrossing and genetic transformation to introduce desired traits like herbicide resistance, disease resistance, and improved nutritional quality, along with the use of tissue culture and regenerable cells to produce plants with consistent physiological and morphological characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional breeding techniques are used to develop soybean varieties, then genetic diversity and adaptability are maintained, but the breeding process becomes time-consuming and unpredictable

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

Solution Approach 1:

The patent employs preliminary action by pre-selecting parental lines with desired traits (disease resistance, yield potential, nutritional quality) and using molecular markers to identify and track specific genes of interest throughout the breeding process. This allows breeders to predict outcomes earlier and make informed decisions before completing the full breeding cycle, thereby reducing time loss while maintaining genetic diversity.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If conventional breeding techniques are used to develop soybean varieties, then natural genetic variation is preserved, but the ability to introduce specific desirable characteristics becomes limited and unpredictable

Engineering Contradiction:
Improvegenetic variationVSAvoidtrait introduction precision
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The patent implements feedback mechanisms through molecular marker-assisted selection, where DNA markers linked to desired traits are used to monitor and select plants carrying specific genes of interest during each generation of breeding. This feedback loop allows precise tracking of trait inheritance and enables breeders to make targeted selections, thereby introducing specific desirable characteristics with high precision while preserving overall genetic variation.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If multiple breeding objectives are pursued simultaneously (yield, disease resistance, nutritional quality), then comprehensive variety improvement is achieved, but the complexity and difficulty of the breeding program increases

Engineering Contradiction:
Improvemulti-trait improvementVSAvoidbreeding program complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the multi-trait breeding program into distinct modules: (1) selection of parental lines with specific trait combinations, (2) molecular marker development for each target trait, (3) systematic screening for disease resistance, (4) yield potential evaluation, and (5) nutritional quality analysis. This segmented approach allows each trait to be addressed systematically while reducing overall program complexity through organized, stepwise progression.

Inventive Principle:
Principle #1Segmentation
