Hybrid Maize X17T132 Breeding for Uniform Stress-Resistant Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid maize varieties often lack desirable traits such as resistance to diseases and insects, heat tolerance, drought resistance, and improved yield, with non-uniform plant characteristics affecting agricultural efficiency.
Innovation Solution
Development of a novel maize hybrid variety X17T132 through crossing and introgression of genetic loci conferring traits like male sterility, disease resistance, and herbicide tolerance, combined with cytoplasmic inheritance for male sterility and regenerable tissue culture to maintain uniformity and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding is used to develop new maize varieties, then desirable traits such as disease resistance and yield can be combined, but the process is time-consuming and results in non-uniform plant characteristics
Solution Approach 1:
The patent employs preliminary action by pre-establishing uniform inbred parental lines with specific desirable traits (disease resistance, yield potential) through multiple generations of selective breeding before hybridization. This preliminary preparation of standardized parental material accelerates the overall breeding process while ensuring uniform plant characteristics in the resulting hybrid maize variety.
2Adaptability or versatility
If multiple desirable traits are combined in a single hybrid through traditional breeding, then resistance to diseases and insects, heat tolerance, and drought resistance can be achieved, but plant uniformity is compromised
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding process into distinct stages: first developing uniform inbred parental lines with specific trait combinations, then crossing these standardized lines to produce the hybrid. This segmentation allows each parental line to be optimized for particular traits while maintaining internal uniformity, and the resulting hybrid inherits both the trait diversity and plant uniformity from its standardized parents.
Solution Approach 2:
The patent employs local quality by assigning different desirable traits to different parental lines (e.g., one parent optimized for disease resistance, another for yield potential and stress tolerance). Each parent contributes specific local qualities or trait combinations, and the hybrid integrates these complementary traits while maintaining overall plant uniformity through the controlled cross between genetically standardized parents.
3Stability of the object's composition
If inbred varieties are crossed to produce hybrids, then uniformity of plant characteristics is improved, but the process requires complex breeding programs
Solution Approach 1:
The patent extracts and isolates the essential requirement for hybrid uniformity (genetic standardization of parents) from the complex overall breeding program. By focusing on developing uniform inbred parental lines through systematic selfing and selection, and then simply crossing these standardized parents, the patent separates the uniformity-generation step from the trait-introduction steps, simplifying the breeding program structure while achieving the desired plant uniformity.
