Maize Inbred PH2DMC Double Haploid Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maize breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and improved agronomic qualities into a single variety, leading to inconsistencies in crop uniformity and yield.
Innovation Solution
Development of the novel maize variety PH2DMC, which is created through a process involving double haploid breeding and locus conversion, allowing for the introgression of specific traits such as drought resistance, disease resistance, and improved yield, while maintaining genetic integrity and phenotypic stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding is used to combine desirable traits, then various traits can be integrated into a single variety, but the process is time-consuming and achieves inconsistent uniformity and yield
Solution Approach 1:
The patent applies preliminary action by using double haploid technology to create inbred lines that are genetically fixed after only one generation of selfing, rather than requiring multiple generations of traditional inbreeding. This preliminary genetic fixation dramatically reduces the time needed to develop stable inbred lines while maintaining the ability to combine desirable traits through subsequent hybridization.
Solution Approach 2:
The patent changes the breeding parameter from traditional sequential selfing over multiple generations to a single-generation double haploid approach. This parameter change in the breeding methodology reduces the time required to achieve genetic uniformity while maintaining trait combination capabilities through modern breeding techniques.
2Stability of the object's composition
If traditional inbreeding is used to achieve uniformity, then genetic uniformity can be obtained, but the process requires multiple generations and achieves inconsistent results
Solution Approach 1:
The patent applies preliminary action by using double haploid technology to create inbred lines that are genetically fixed after only one generation of selfing, rather than requiring multiple generations of traditional inbreeding. This preliminary genetic fixation dramatically reduces the time needed to develop stable inbred lines while maintaining the ability to combine desirable traits through subsequent hybridization.
Solution Approach 2:
The patent changes the breeding parameter from traditional sequential selfing over multiple generations to a single-generation double haploid approach. This parameter change in the breeding methodology reduces the time required to achieve genetic uniformity while maintaining trait combination capabilities through modern breeding techniques.
3Adaptability or versatility
If multiple desirable traits are integrated into a single variety, then improved agronomic quality can be achieved, but consistency and reliability of performance vary
Solution Approach 1:
The patent applies preliminary action by using double haploid technology to create inbred lines that are genetically fixed after only one generation of selfing, rather than requiring multiple generations of traditional inbreeding. This preliminary genetic fixation dramatically reduces the time needed to develop stable inbred lines while maintaining the ability to combine desirable traits through subsequent hybridization.
Solution Approach 2:
The patent replaces the mechanical, time-consuming process of traditional multi-generational inbreeding with a more efficient double haploid technology. This substitution enables the creation of genetically stable inbred lines faster and more reliably, improving the consistency of performance for varieties with multiple desirable traits.
