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 5PHVN18, which combines improved traits like resistance to aerial web blight, aphids, and environmental stresses, along with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to enhance breeding efficiency and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine 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:
Improveyield stability and disease resistanceVSAvoidbreeding development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-screening and selecting parent lines with desired traits (disease resistance, yield potential) before initiating the breeding program. This advance preparation of germplasm with known desirable characteristics accelerates the breeding process while ensuring the final variety meets performance targets, reducing the overall development time from 6-12 years

Inventive Principle:
Principle #10Preliminary action

2Productivity

If multiple crossing and selection steps are performed to achieve stable high-yielding varieties, then the variety shows maximal yield over different conditions, but the process becomes complex and resource-intensive

Engineering Contradiction:
Improveseed yieldVSAvoidbreeding process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The breeding program is segmented into distinct phases: parent line selection, initial crossing, F1 evaluation, backcrossing if needed, and multi-environment testing. Each phase has specific objectives and selection criteria, allowing systematic progression toward the goal of high-yielding stable varieties without overwhelming complexity. This structured segmentation manages the breeding process efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent develops varieties that are universally adaptable to multiple environments and conditions through testing across different locations and years. The selected varieties demonstrate consistent performance (maximal yield over different conditions) across diverse agricultural settings, making them universally applicable and reducing the need for variety-specific management practices

Inventive Principle:
Principle #6Universality (Multi-functionality)
