Inbred Corn Line CB18615S2 Yield Stability Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for stable, high-yielding corn hybrids that are agronomically sound to maximize ear or kernel production, addressing the challenge of developing superior parental lines for corn breeding.
Innovation Solution
The development of a novel inbred corn line, CB18615S2, which includes methods for producing seeds, plants, and derived corn lines with specific morphological and physiological characteristics, utilizing mutagenesis, TILLING screening, and genetic modification to introduce desired traits such as herbicide resistance, disease resistance, and improved nutritional quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional breeding methods are used to develop corn hybrids, then parental lines can be selected, but yield and agronomic performance are limited
Solution Approach 1:
The patent applies parameter changes by modifying the genetic composition of corn parental lines through controlled crossing and selection. Specific genetic parameters are altered to achieve superior yield and stability in hybrids, transforming the genetic parameters of the parental lines to produce offspring with enhanced productivity while maintaining reliability through systematic breeding protocols
2Adaptability or versatility
If genetic modification techniques are applied to introduce desired traits, then traits like herbicide resistance and nutritional quality are improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding process into distinct stages: selecting parental lines with specific traits, controlled crossing to introduce desired traits, and systematic selection of offspring. This segmentation allows for the introduction of diverse traits like herbicide resistance and nutritional quality while managing process complexity through organized, step-by-step procedures
Solution Approach 2:
The patent uses controlled crossing as an intermediary mechanism to introduce desired traits. By using specific parental lines as intermediaries that carry desired traits (such as herbicide resistance or nutritional enhancements), the breeding process can systematically introduce these traits into new hybrids without directly applying complex genetic modification techniques
