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 technologies face challenges in efficiently combining these traits in a single variety.

Innovation Solution

The development of the soybean variety XB45Y10, which is the result of careful breeding and selection, combining traits like resistance to aerial blight, brown stem rot, and improved fatty acid composition, along with molecular marker profiles for identification and introgression of new traits, facilitates efficient breeding and trait introduction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding processes are used to combine multiple desirable traits, then disease resistance and yield improvement are achieved, but the breeding process becomes time-consuming and resource-intensive

Engineering Contradiction:
Improvedisease resistanceVSAvoidbreeding process duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-characterizing parental lines with specific disease resistance traits (aerial blight, brown stem rot, sudden death syndrome) and fatty acid profiles before crossing. This allows the breeding program to start with parents that already possess the desired traits, reducing the time needed for trait discovery and selection in later generations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through systematic evaluation of F1 and F2 progeny for both disease resistance traits and fatty acid composition. By measuring these traits in early generations and using this information to guide selection decisions, the breeding process accelerates while maintaining reliability of the desired traits.

Inventive Principle:
Principle #23Feedback

2Productivity

If extensive breeding and selection is performed to achieve stable, high-yielding varieties with multiple traits, then variety performance is improved, but resource consumption increases

Engineering Contradiction:
Improveseed yieldVSAvoidbreeding resource consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent segments the breeding objective into distinct, measurable components: disease resistance (aerial blight, brown stem rot, sudden death syndrome), yield traits, and fatty acid profiles. By evaluating and selecting for each component separately in the F1 and F2 generations, the program efficiently combines multiple traits without requiring exhaustive breeding cycles, thus improving productivity while managing resource consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes parameters by establishing specific target ranges for fatty acid composition (oleic, linoleic, linolenic acids) and disease resistance scores. This parameter-based selection approach allows for precise tracking of trait improvement and enables more efficient breeding decisions compared to traditional phenotypic selection alone, reducing the resources needed to achieve high-yielding varieties with multiple desirable traits.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple traits are combined in a single variety through breeding, then variety versatility is improved, but breeding program complexity increases

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding program structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the complex multi-trait breeding program into manageable components by evaluating specific disease resistance traits (aerial blight, brown stem rot, sudden death syndrome) and fatty acid profiles separately in the F1 and F2 generations. This segmented approach to trait evaluation and selection simplifies the overall breeding program structure while still achieving combination of multiple desirable traits in the final variety.

Inventive Principle:
Principle #1Segmentation
