Solution Overview

Problem

Current soybean breeding processes are time-consuming and resource-intensive, aiming to develop stable, high-yielding varieties with desirable traits such as disease resistance, drought tolerance, and improved fatty acid profiles, while existing methods face challenges in efficiently combining these traits in a single variety.

Innovation Solution

The development of a novel soybean variety, XB33U13, which is the result of careful breeding and selection, combining traits like resistance to aerial web blight, aphid antibiosis, and improved fatty acid profiles, through a process involving backcrossing and genetic marker-assisted breeding to introduce desired traits and achieve phenotypic stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional soybean breeding methods are used to combine multiple desirable traits, then trait combination is achieved, but the breeding process becomes time-consuming and resource-intensive

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding process duration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs marker-assisted selection where DNA markers provide feedback on the presence of desired traits during breeding. This allows breeders to track and select for multiple traits simultaneously without waiting for phenotypic expression, significantly reducing the time required to combine desirable traits while maintaining accuracy in trait selection.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If extensive breeding and selection processes are conducted to achieve phenotypic stability, then trait stability is improved, but resource consumption increases

Engineering Contradiction:
Improvephenotypic stabilityVSAvoidbreeding resource consumption
Core Design Contradiction:
Stability of the object's compositionVSLoss of energy

Solution Approach 1:

The patent uses DNA markers to detect and confirm the presence of desired traits at early developmental stages, allowing breeders to make selection decisions before extensive phenotypic expression occurs. This preliminary genetic screening reduces the number of breeding cycles needed to achieve phenotypic stability, thereby conserving time and resources while ensuring trait stability in the final variety.
