Hybrid Maize Variety 89458876 Trait Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional plant breeding methods struggle to consistently incorporate multiple desirable traits such as disease resistance, drought tolerance, and improved yield into maize crops, while maintaining uniformity and stability necessary for mechanical harvesting.
Innovation Solution
Development of a novel maize hybrid variety 89458876, produced by crossing two inbred varieties, which includes genetic loci for traits like male sterility, herbicide tolerance, and disease resistance, introduced through locus conversion, backcrossing, and transformation, allowing for the production of seeds and plants with specific physiological and morphological characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding methods are used to incorporate multiple desirable traits, then trait diversity is improved, but manufacturing precision (uniformity of plant characteristics) deteriorates
Solution Approach 1:
The breeding program segments the incorporation of traits into distinct stages: first developing inbred lines with specific traits through controlled crosses, then combining these inbred lines to create hybrids. This segmentation allows each stage to focus on specific traits while maintaining overall uniformity through systematic breeding protocols.
Solution Approach 2:
The patent employs parameter changes by systematically varying breeding parameters such as selection criteria, crossing schemes, and environmental conditions during the breeding process. This allows precise control over which traits are incorporated and how they are expressed, achieving both diversity and uniformity.
2Adaptability or versatility
If multiple desirable traits are combined into a single hybrid, then adaptability is improved, but device complexity (breeding program complexity) deteriorates
Solution Approach 1:
The complex breeding program is segmented into manageable components: developing specific inbred lines with individual traits, then combining them in controlled crosses. This segmentation reduces the complexity of managing multiple traits simultaneously by breaking the problem into smaller, controllable steps.
Solution Approach 2:
The patent applies preliminary action by first developing and stabilizing inbred lines with specific desirable traits before combining them to create the final hybrid. This preliminary development ensures that each component is optimized independently, reducing the overall complexity of the breeding program.
3Ease of operation
If uniformity of plant characteristics is maintained for mechanical harvesting, then ease of operation is improved, but loss of time (breeding duration) deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-establishing inbred lines with uniform characteristics suitable for mechanical harvesting before creating the final hybrid. This allows the uniformity requirement to be met without extending the overall breeding duration, as the inbred lines are prepared in advance.
Solution Approach 2:
The breeding program utilizes parameter changes by adjusting selection criteria and environmental conditions to accelerate the development of uniform plant characteristics. This allows uniformity to be achieved more rapidly, reducing the time loss while maintaining ease of operation for mechanical harvesting.
