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 tolerance to environmental stresses, while existing methods are inefficient and take around six to twelve years from the first cross to delivering finished seed to farmers.

Innovation Solution

The introduction of soybean variety 5PDST38, which is stable, high-yielding, and agronomically sound, along with methods for crossing, introgressing transgenic or mutant traits, and characterizing the variety to produce plants with improved traits, facilitating the development of new soybean varieties and plant parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional soybean breeding methods are used to combine desirable traits, then the resulting varieties have improved yield and stress tolerance, but the development process takes six to twelve years and requires significant resources

Engineering Contradiction:

Improveyield and stress toleranceVSAvoiddevelopment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-characterizing soybean variety 5PDST38 with multiple desirable traits (high yield, stress tolerance, disease resistance) before use in breeding programs. This pre-prepared genetic material serves as a ready-to-use foundation, eliminating the need for time-consuming trait combination processes and enabling breeders to start with already-optimized genetic stock.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses soybean variety 5PDST38 as an intermediary genetic resource that facilitates trait transfer between different soybean lines. By crossing 5PDST38 with other varieties, breeders can efficiently introgress desirable traits without performing multiple sequential crosses and selections, thus reducing development time while maintaining trait reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional breeding methods are used to develop new varieties, then genetic diversity and trait combination are achieved, but the process is inefficient and resource-intensive

Engineering Contradiction:

Improvetrait combinationVSAvoidbreeding efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-characterizing soybean variety 5PDST38 with multiple desirable traits (high yield, stress tolerance, disease resistance) before use in breeding programs. This pre-prepared genetic material serves as a ready-to-use foundation, eliminating the need for time-consuming trait combination processes and enabling breeders to start with already-optimized genetic stock.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent enables efficient copying of desirable traits from variety 5PDST38 to new varieties through controlled crossing and backcrossing programs. The well-characterized genetic profile of 5PDST38 allows breeders to reliably copy specific trait combinations into new genetic backgrounds, accelerating the development of adapted varieties without requiring extensive re-characterization.

Inventive Principle:

Principle #26Copying

3Reliability

If extensive crossing and selection programs are conducted to improve soybean varieties, then desirable traits are combined, but the process requires precise planning and minimum changes in direction

Engineering Contradiction:

Improvetrait stabilityVSAvoidbreeding program complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses soybean variety 5PDST38 as an intermediary genetic resource that facilitates trait transfer between different soybean lines. By crossing 5PDST38 with other varieties, breeders can efficiently introgress desirable traits without performing multiple sequential crosses and selections, thus reducing development time while maintaining trait reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies parameter changes by utilizing the specific genetic parameters of variety 5PDST38 (maturity group, oil content, protein content, stress tolerance levels) as fixed reference points in breeding programs. These characterized parameters serve as stable benchmarks that guide crossing decisions and selection criteria, simplifying program management while ensuring trait stability in resulting varieties.
