Solution Overview

Problem

The development of new corn inbred lines is hindered by the unpredictability of genetic traits due to environmental factors and the complexity of inheritance, leading to high research costs and lengthy breeding processes, with existing methods struggling to efficiently combine desirable traits like yield, disease resistance, and drought tolerance.

Innovation Solution

The introduction of the inbred corn line BB93, which is a yellow dent corn with superior characteristics, including high yield, drought tolerance, and resistance to stalk and root lodging, achieved through a combination of traditional breeding methods and potential genetic modification techniques, such as backcrossing and transgenic approaches, to stabilize desirable traits across different environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional breeding methods are used to combine desirable traits, then genetic diversity is improved, but the breeding process becomes time-consuming and unpredictable

Engineering Contradiction:
Improvegenetic diversityVSAvoidbreeding process duration
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent creates a standardized inbred line BB93 with pre-stabilized desirable traits (high yield, drought tolerance, lodging resistance) that can be directly used as a parental line. This preliminary development of a ready-to-use genetic foundation eliminates the need for time-consuming trait combination experiments in subsequent breeding programs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The inbred line BB93 represents a specific genetic parameter configuration that has been optimized for multiple traits simultaneously. By fixing these genetic parameters in a stable inbred line, breeders can reliably predict and achieve desired outcomes without repeated trial and error cycles.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If multiple breeding cycles are performed to stabilize traits, then trait consistency is improved, but research costs increase

Engineering Contradiction:
Improvetrait consistencyVSAvoidresearch costs
Core Design Contradiction:
Stability of the object's compositionVSLoss of energy

Solution Approach 1:

The inbred line BB93 has already undergone multiple breeding cycles and stabilization processes during its development. This preliminary stabilization work is completed once, and the resulting line can be repeatedly used without requiring additional stabilization cycles, thereby amortizing the research costs over many breeding applications.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The standardized inbred line BB93 serves as a reusable genetic template that can be copied and used in multiple breeding programs. Once the desirable trait combination is established in BB93, this genetic configuration can be replicated across different breeding projects without repeating the expensive stabilization process.

Inventive Principle:
Principle #26Copying

3Measurement precision

If environmental factors are controlled to predict genetic traits, then measurement precision is improved, but breeding program complexity increases

Engineering Contradiction:
Improvegenetic trait prediction accuracyVSAvoidbreeding program complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The inbred line BB93 has been developed with stabilized genetic parameters that reduce the influence of environmental variability on trait expression. This genetic stabilization allows for more accurate prediction of trait inheritance without requiring complex environmental control measures.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The inbred line BB93 inherently possesses stable and consistent trait expression that does not require complex external management or environmental controls to predict outcomes. The line's genetic constitution itself provides the stability needed for accurate prediction, eliminating the need for additional complexity in breeding program management.

Inventive Principle:
Principle #25Self-service
