Maize Inbred PH47WV Breeding via Preliminary Action and Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process, taking six to twelve years, and existing technologies face challenges in combining desirable traits such as disease resistance, drought tolerance, and high yield in a single variety that is agronomically sound across various conditions and environments.
Innovation Solution
The introduction of the novel maize variety PH47WV, which involves crossing with other maize plants to introduce traits like male sterility, disease resistance, and improved agronomic characteristics through backcross conversion, genetic manipulation, and transformation, along with specific breeding processes to produce stable and high-yielding maize plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding processes are used to develop new maize varieties, then the variety can be agronomically sound and stable, but the development time is extremely long (6-12 years)
Solution Approach 1:
The patent applies preliminary action by pre-selecting and pre-characterizing parent inbreds with desirable traits before the actual hybrid development. The inbreds are evaluated for yield, disease resistance, and other traits in advance, allowing the breeding process to start with a ready-to-use genetic foundation rather than beginning from scratch, thus reducing overall development time while maintaining agronomic soundness
Solution Approach 2:
The patent uses copying by utilizing existing well-characterized inbred lines and their known genetic properties as templates for hybrid development. Instead of creating entirely new varieties from scratch, the invention copies and combines proven genetic components (inbreds) to create hybrids that inherit desirable traits, significantly accelerating the development process while maintaining reliability
2Adaptability or versatility
If multiple desirable traits are combined in a single variety, then the variety becomes more versatile and high-yielding, but the breeding complexity and time required increase
Solution Approach 1:
The patent applies segmentation by dividing the complex trait combination process into separate stages: first selecting parent inbreds with specific traits, then combining them through controlled crosses. This segmented approach allows each trait (yield, disease resistance, stress tolerance) to be selected and combined systematically rather than attempting to create all traits simultaneously, reducing breeding complexity while achieving versatility
Solution Approach 2:
The patent uses universality by developing inbred lines that possess multiple desirable traits simultaneously (multi-functional inbreds). These universal inbreds can serve as parents for multiple different hybrid combinations, allowing a single inbred to contribute to varieties with diverse trait combinations, thereby reducing overall breeding complexity while increasing adaptability
