Cotton Variety 11R115B2R2 Breeding via Segmentation
Find Innovative SolutionsGenerate Solutions
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, leading to high research costs and time-consuming processes.
Innovation Solution
The development of the cotton variety 11R115B2R2, which is insect-protected and herbicide-tolerant, achieved through conventional breeding and backcrossing, incorporating transgenic genes for resistance and tolerance, allowing for the introduction of desired traits and improved agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering 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 becomes unpredictable and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental lines with specific desirable traits (insect protection, herbicide tolerance, disease resistance) before crossing. This preliminary selection and characterization of parents reduces the unpredictability and time required in subsequent breeding generations, as the desired traits are already established in the parental material.
2Reliability
If multiple traits are incorporated into cotton varieties, then resistance and tolerance improve, but breeding complexity increases
Solution Approach 1:
The patent applies segmentation by developing parental lines that each carry specific, isolated traits (one parent with insect protection, another with herbicide tolerance and disease resistance). This segmentation allows breeders to systematically combine traits through controlled crosses, reducing overall breeding program complexity while maintaining reliable multi-trait resistance in the final variety.
3Productivity
If research and development is intensified to develop superior varieties, then fiber yield and quality improve, but research costs increase
Solution Approach 1:
The patent applies copying by utilizing existing parental lines with proven desirable traits as templates for developing new varieties. By copying successful trait combinations from established parents (such as the B2RF parent with insect protection and herbicide tolerance), researchers can develop new superior varieties more efficiently, reducing R&D costs while maintaining high fiber yield and quality standards.
