Maize Variety PH13JC Breeding Using Genetic Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maize breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and uniformity, which are essential for efficient crop production and mechanical harvesting.
Innovation Solution
Development of the novel maize variety PH13JC, which involves crossing and backcrossing to introduce specific traits, and the use of genetic marker profiles for identifying and verifying the genetic integrity of PH13JC in hybrid seeds and plants, allowing for locus conversions and hybrid production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding methods are used to combine desirable traits, then disease resistance and drought tolerance can be achieved, but the time required for breeding and the complexity of the breeding process increase
Solution Approach 1:
The patent applies preliminary action by developing inbred line PH13JC with pre-introgressed desirable traits through backcrossing before hybrid production. The inbred line is prepared in advance with confirmed disease resistance, drought tolerance, and uniformity characteristics, allowing rapid hybrid development without extensive field testing at later stages.
Solution Approach 2:
The patent uses genetic marker profiles as copies or fingerprints to verify and track the transmission of specific genetic traits. Molecular markers serve as replicable identifiers that allow breeders to confirm the presence of desired genes without phenotypic testing, accelerating the breeding process while maintaining reliability.
2Productivity
If multiple desirable traits are combined in a single variety, then yield and stress resistance improve, but the uniformity of plant characteristics may be compromised
Solution Approach 1:
The patent applies local quality by introducing specific desirable traits into specific genetic backgrounds through backcrossing. The inbred line PH13JC contains targeted introductions of disease resistance and drought tolerance genes while maintaining the uniformity of the base genome, allowing different regions of the genome to have different functions (yield, resistance, uniformity) without compromising overall plant consistency.
Solution Approach 2:
The patent uses parameter changes by employing molecular marker analysis to precisely track and verify genetic composition during breeding. This allows real-time monitoring of trait inheritance and genome composition, enabling adjustments to maintain uniformity while incorporating multiple desirable traits through controlled backcrossing and selection.
3Measurement precision
If genetic marker profiles are used to verify genetic integrity, then the precision of trait identification improves, but the complexity of analysis and verification processes increases
Solution Approach 1:
The patent extracts specific molecular markers from complex genomic data to create simplified verification profiles. Instead of analyzing the entire genome, selected marker loci are used to track specific traits of interest, reducing analytical complexity while maintaining high precision in identifying disease resistance, drought tolerance, and other desirable characteristics.
