Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in maize breeding is to combine desirable traits such as resistance to diseases and insects, heat, and drought tolerance with improved yield and agronomic quality, while maintaining uniformity and stability in hybrid varieties.
Innovation Solution
The development of the hybrid maize variety X180108, produced by crossing proprietary Pioneer Hi-Bred International inbred varieties, which incorporates locus conversion and transformation processes to introduce specific traits, enhancing resistance and yield while maintaining genetic integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding methods are used to combine multiple desirable traits, then the complexity of the breeding program increases, but the ability to maintain uniformity and stability of the hybrid variety decreases
Solution Approach 1:
The patent segments the breeding process by using separate inbred parental lines, each carrying specific desirable traits (disease resistance, insect resistance, drought tolerance, heat tolerance). By crossing these pre-characterized inbreds, the hybrid inherits a segmented combination of traits while maintaining overall uniformity through controlled pollination and selection.
Solution Approach 2:
The patent applies preliminary action by developing and characterizing inbred parental lines before crossing. Each inbred line is pre-selected and pre-characterized for specific traits (e.g., disease resistance, drought tolerance) through multiple generations of inbreeding and selection, ensuring that the resulting hybrid will uniformly express the desired trait combinations.
2Productivity
If multiple traits are combined in a single hybrid to improve resistance and yield, then the genetic complexity increases, but the difficulty of maintaining trait uniformity across generations increases
Solution Approach 1:
The patent applies local quality by assigning specific traits to specific parental inbreds. Each inbred line is optimized for particular local qualities (e.g., one parent for disease resistance, another for drought tolerance), and the hybrid inherits these localized trait expressions, maintaining uniformity through the controlled combination of these specialized parental lines.
Solution Approach 2:
The patent creates a composite genetic structure by combining multiple inbred lines, each contributing specific genetic components for different traits. The hybrid represents a composite of these parental genomes, where each parental contribution maintains its characteristic traits while forming a unified hybrid variety with consistent uniformity.
3Reliability
If proprietary inbred varieties are crossed to develop new hybrids, then the genetic integrity of parental lines is maintained, but the time and resources required for breeding increase
Solution Approach 1:
The patent applies preliminary action by pre-developing and characterizing proprietary inbred parental lines with known genetic integrity and desired traits. This preliminary work is done once and can be reused across multiple hybrid developments, reducing the time required for new breeding programs while maintaining genetic integrity through established inbreeding protocols.
Solution Approach 2:
The patent applies universality by creating proprietary inbred lines that can serve multiple functions across different hybrid combinations. A single inbred line with desirable traits can be crossed with multiple different partners to produce various hybrids, all maintaining the genetic integrity and trait expression of the original inbred, thereby reducing overall breeding time and resources.
