Solution Overview

Problem

Cotton breeders face challenges in preserving desired traits while maintaining the unique characteristics of a specific variety during the breeding process, particularly in achieving genetic conformity and introducing specific traits through backcrossing or genetic transformation.

Innovation Solution

The development of the cotton variety FM 6000AXTP involves a breeding process that includes recurrent backcrossing, selection, and genetic transformation to introduce desired traits while retaining the unique characteristics, utilizing molecular markers for genetic conformity, and producing essentially derived varieties with a genetic identity of 90-100% similarity to the initial variety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If backcrossing is used to introduce specific traits, then desired traits such as herbicide resistance and insect resistance are introduced, but genetic conformity to the original variety may be compromised

Engineering Contradiction:

Improvedesired traitsVSAvoidgenetic conformity

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Molecular markers are used throughout the backcrossing process to continuously monitor and verify genetic conformity to the original variety while tracking the introduction of desired traits. This feedback mechanism allows breeders to make informed decisions at each generation to maintain genetic purity while achieving trait introduction

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Traditional phenotypic selection methods are replaced with molecular marker-based genotypic selection. This substitution allows for more precise and early detection of genetic conformity and trait presence, enabling more efficient backcrossing with fewer generations required to achieve both genetic conformity and desired trait introduction

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If multiple backcrossing generations are performed to achieve genetic conformity, then genetic identity increases to 90-100% similarity, but breeding time and complexity increase

Engineering Contradiction:

Improvegenetic identityVSAvoidbreeding time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

Phenotypic selection across multiple generations is replaced with molecular marker-based selection that can detect genetic conformity at the DNA level. This allows breeders to identify conforming plants much earlier in the breeding process, reducing the number of generations needed to achieve 90-100% genetic identity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

Molecular marker analysis is performed at each generation of backcrossing to preliminarily identify plants that maintain genetic conformity. This preliminary action allows early elimination of non-conforming plants before investing resources in further breeding cycles, thereby reducing overall breeding time

Inventive Principle:

Principle #10Preliminary action
