Hybrid Maize Trait Introgression for Uniform Stress Tolerance
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 in plant characteristics, which are crucial for mechanical harvesting and agronomic quality.
Innovation Solution
The development of a novel maize hybrid variety X10T086, 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
1Reliability
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 divides the breeding process into distinct segments: developing separate inbred lines with specific traits, then crossing them to create hybrids. This segmentation allows each parent line to be optimized for particular 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 tolerance, drought tolerance, and yield characteristics while maintaining uniformity through controlled crossbreeding
2Adaptability or versatility
If traditional plant breeding is used to develop new varieties, then desirable traits can be combined, but the complexity of the breeding process increases
Solution Approach 1:
The patent performs preliminary actions by developing and stabilizing inbred parent lines before creating the hybrid. The parent lines are pre-selected and pre-characterized for specific traits, which simplifies the subsequent hybridization process and reduces overall breeding complexity
