Solution Overview

Problem

The development of new soybean varieties is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as high yield, disease resistance, and environmental tolerance, while existing methods are inefficient and directionally unstable, taking six to twelve years from the first cross to delivering finished seed to farmers.

Innovation Solution

The introduction of the novel soybean variety 5PUHP43, which combines improved traits like resistance to aerial web blight, aphids, and other diseases, along with enhanced agronomic characteristics, through methods involving crossing, introgression of transgenic or mutant traits, and characterization, facilitating the production of stable and high-yielding soybean plants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine multiple desirable traits, then the variety achieves high yield and disease resistance, but the development process takes six to twelve years and requires extensive resources

Engineering Contradiction:
Improvestability and high yieldVSAvoiddevelopment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-screening and selecting parent lines with specific desirable traits (disease resistance, yield potential, agronomic characteristics) before initiating the breeding program. This advance preparation and selection of genetically superior parents accelerates the development process while ensuring the final variety achieves high yield and stability.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If traditional breeding methods are used to combine multiple desirable traits, then the variety achieves disease resistance and agronomic improvement, but the process requires extensive resources and precise planning

Engineering Contradiction:
Improvedisease resistanceVSAvoidresource efficiency
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent employs copying by utilizing molecular markers to identify and track specific disease resistance genes and desirable traits through generations. This marker-assisted selection allows breeders to copy proven genetic traits from parent lines into new varieties more efficiently, reducing the need for extensive field testing and resource consumption while maintaining reliable disease resistance.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If traditional breeding methods are used to develop new varieties, then the process achieves trait combination, but the directionality and efficiency of the process are poor

Engineering Contradiction:
Improvetrait combinationVSAvoidbreeding efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements feedback through systematic evaluation and selection processes at multiple stages of breeding. Molecular markers provide real-time feedback on the presence and combination of desirable traits, allowing breeders to make informed decisions about which lines to advance. This feedback mechanism ensures directional progress toward specific breeding goals and improves overall breeding efficiency by eliminating inferior lines early in the process.
