Maize Inbred PH2G07 Trait Integration via Preliminary Action
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new maize varieties and hybrids is a time-consuming process that requires precise planning and efficient resource use, aiming to combine desirable traits such as disease resistance, drought tolerance, and high yield, while maintaining stability across different conditions and environments.
Innovation Solution
The introduction of the novel maize variety PH2G07, which involves crossing with another maize plant to introduce specific traits like male sterility, herbicide tolerance, and disease resistance through backcross conversion and genetic transformation, along with processes for producing hybrid seeds and plants with enhanced agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional maize breeding processes are used to combine desirable traits, then trait integration is achieved, but the development time becomes excessively long (6-12 years)
Solution Approach 1:
The patent applies preliminary action by pre-characterizing inbred lines with specific desirable traits (disease resistance, drought tolerance, yield potential) before hybridization. This allows breeders to select parents with known trait profiles, reducing the time needed for trait integration in later generations compared to traditional breeding where traits are discovered and combined during the lengthy development process
2Reliability
If multiple desirable traits are combined in a single variety, then agronomic performance is improved, but the breeding program complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: (1) development and characterization of specialized inbred lines with specific traits, (2) strategic hybridization to combine these lines, and (3) evaluation of hybrid performance. This segmented approach manages complexity by handling one trait or a limited set of traits at a time in each phase, rather than attempting to combine multiple traits simultaneously
3Stability of the object's composition
If conventional breeding methods are used to ensure stability across environments, then variety stability is achieved, but productivity of the breeding process decreases
Solution Approach 1:
The patent applies preliminary action by conducting multi-environment evaluations of parent inbred lines before hybridization. This preliminary characterization of parental stability across different environments allows for more predictable hybrid performance, reducing the need for extensive re-evaluation in later breeding stages and thereby improving overall breeding efficiency
