Solution Overview

Problem

Current cotton breeding methods face challenges in developing new, superior cotton varieties that combine desirable traits such as higher fiber yield, earlier maturity, disease resistance, and tolerance to drought and heat, due to the unpredictability of genetic combinations and the complexity of inheritance, which requires extensive research and resources.

Innovation Solution

The development of the cotton variety 10R015B2R2, which is insect-protected and herbicide-tolerant, achieved through conventional breeding and backcrossing, incorporating traits like Bollgard II and Roundup Ready Flex, allowing for the production of hybrid seeds and plants with improved agronomic characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional breeding methods are used to develop new cotton varieties, then genetic combinations can be generated, but the process requires extensive research and resources due to unpredictability and inheritance complexity

Engineering Contradiction:
Improvetrait combination capabilityVSAvoidbreeding process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by modifying specific genetic loci through targeted backcrossing and selection. Instead of relying on random genetic recombination across the entire genome, the breeding process focuses on changing specific parameters (traits) at defined loci while maintaining the genetic background of the recurrent parent. This approach transforms the unpredictable nature of conventional breeding into a more controlled process where specific traits can be introduced or modified with known inheritance patterns.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If multiple parental lines are crossed to achieve desirable traits, then trait diversity increases, but the inheritance complexity and research requirements increase significantly

Engineering Contradiction:
Improvetrait diversityVSAvoidbreeding cycle time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs preliminary action by pre-selecting parental lines with known desirable traits and established inheritance patterns before initiating the breeding program. The recurrent parent is carefully chosen to possess the desired genetic background, and donor parents are selected for specific traits to be introduced. This preliminary preparation allows the breeding process to proceed more efficiently, as the inheritance expectations are known in advance, reducing the time required for evaluation and selection across multiple generations.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If extensive breeding programs are conducted to combine desirable traits, then variety improvement is achieved, but resource requirements and research efforts increase

Engineering Contradiction:
Improvevariety performance stabilityVSAvoidbreeding resources
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies the extraction principle by isolating and focusing on specific traits of interest for introduction or modification, rather than attempting to improve all traits simultaneously. The breeding program extracts the essential genetic components needed for the desired variety performance and concentrates resources on those specific loci. This approach allows for more efficient resource allocation, as breeding efforts are directed toward achieving specific performance targets rather than conducting comprehensive improvements across the entire genome.

Inventive Principle:
Principle #2Taking out (Extraction)
