Maize Hybrid Trait Introgression for Uniform Stress-Tolerant Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid maize development methods struggle to combine desirable traits such as disease resistance, heat and drought tolerance, and improved yield while maintaining uniformity and stability, which are crucial for commercial crop production.
Innovation Solution
The development of the maize hybrid variety X95T028, produced by crossing specific inbred varieties and incorporating genetic loci for traits like male sterility, disease resistance, and altered metabolism through backcrossing and transformation, along with cytoplasmically-inherited traits to enhance hybrid performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding methods are used to combine multiple desirable traits, then disease resistance, heat and drought tolerance, and yield improvement can be achieved, but uniformity and stability of plant characteristics deteriorate
Solution Approach 1:
The patent segments the breeding process into distinct stages: developing inbred lines with specific traits, then crossing them to produce hybrids. This segmentation allows each parent line to be optimized for specific characteristics while the hybrid combines them uniformly
Solution Approach 2:
The patent merges multiple desirable traits from different inbred parent lines into a single hybrid variety. The hybrid combines disease resistance, heat and drought tolerance, and yield improvement while maintaining uniformity through controlled crossbreeding of homozygous parents
2Reliability
If hybrid maize variety is developed for improved traits, then resistance to diseases, insects, and environmental stresses is enhanced, but the complexity of the breeding process increases
Solution Approach 1:
The patent applies preliminary action by developing and stabilizing inbred parent lines before crossing them. The parent lines are prepared with specific traits and homozygosity established through multiple generations of selfing, which simplifies the subsequent hybridization process
Solution Approach 2:
The patent utilizes self-service through the natural hybridization behavior of maize, where controlled crosses between inbred lines automatically produce uniform F1 hybrids with heterosis, eliminating the need for complex intervention during the crossing process
