Maize Inbred 1PDBW79 Breeding Acceleration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process that takes several years, and there is a continuous need for stable, high-yielding maize varieties that are agronomically sound and can perform well under various conditions and environments.
Innovation Solution
A novel maize variety, designated 1PDBW79, and processes for making 1PDBW79 are provided. This variety can be used to produce seed, plants, and plant parts with specific traits introduced through backcross conversion, genetic manipulation, and transformation. The variety can also include cytoplasmic or nuclear factors for male sterility to prevent self-pollination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding processes are used to develop new varieties, then stable and agronomically sound varieties can be achieved, but the development time becomes excessively long (6-12 years)
Solution Approach 1:
The patent applies preliminary action by pre-establishing a diverse panel of inbred lines with characterized traits before beginning variety development. This allows breeders to select from pre-tested genetic material rather than creating new combinations from scratch, significantly reducing the time required to develop stable, high-yielding varieties while maintaining agronomic soundness.
Solution Approach 2:
The patent utilizes parameter changes by modifying breeding approaches to include molecular markers, genomic selection, and controlled cross-breeding strategies. These changes in breeding parameters accelerate the selection process while maintaining the stability and agronomic quality of resulting varieties, reducing development time without sacrificing reliability.
2Productivity
If multiple desirable traits are combined in a single variety, then yield and stress tolerance improve, but the breeding process complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding process into distinct stages: selecting parent inbred lines with specific traits, performing controlled crosses, and selecting offspring with desired trait combinations. This segmented approach makes the complex process of combining multiple traits more manageable and systematic.
Solution Approach 2:
The patent employs universality by developing inbred lines that serve multiple functions - they can be used as parents for different hybrid combinations, provide multiple desirable traits simultaneously, and serve as genetic resources for various breeding objectives. This multi-functionality reduces overall breeding complexity while achieving high productivity.
3Adaptability or versatility
If conventional breeding methods are used, then genetic diversity can be maintained, but the speed of variety development is slow
Solution Approach 1:
The patent uses molecular markers and genomic tools as intermediaries to accelerate variety development while maintaining genetic diversity. These intermediaries allow for precise tracking and selection of diverse genetic material through generations, enabling faster development without losing the genetic variation necessary for adaptability.
