Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maize breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and uniformity, which are essential for efficient and high-yielding crop production.
Innovation Solution
Development of a novel maize variety, PHF5G, which is homozygous and can be used to produce hybrid seeds through crossing with other maize plants, incorporating traits such as drought resistance, disease resistance, and improved agronomic qualities, along with processes for backcross conversion and transformation to enhance specific traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding techniques are used to combine desirable traits, then disease resistance and drought tolerance can be achieved, but uniformity of plant characteristics and yield consistency deteriorate
Solution Approach 1:
The patent segments the breeding process into distinct generations (P1, P2, F1, F2, F3, F4) with specific selection criteria for each stage. This structured segmentation allows systematic combination of desirable traits while maintaining uniformity through controlled crossing and selection protocols.
Solution Approach 2:
The patent performs preliminary action by pre-selecting parent lines (P1 and P2) with specific desirable traits before crossing. The F1 generation is then selfed multiple times with predetermined selection criteria to ensure uniformity is established early in the breeding process, preventing trait variability from developing.
2Reliability
If traditional plant breeding is used to develop new varieties, then desirable traits can be combined, but the time required for variety development increases
Solution Approach 1:
The patent performs preliminary selection and characterization of parent lines (P1 and P2) with desired traits before initiating the crossing program. This preliminary action ensures that subsequent generations can be developed more rapidly with predetermined selection criteria, reducing overall development time.
Solution Approach 2:
The patent maintains continuous useful action by selfing the F1 generation multiple times (F2, F3, F4) with ongoing selection for desired traits throughout each generation. This continuous selection process accelerates variety development compared to traditional methods by maintaining focused selection pressure across all generations rather than interrupting the process.
3Productivity
If mechanical harvesting is implemented, then crop productivity increases, but uniformity of plant characteristics becomes more critical and harder to achieve
Solution Approach 1:
The patent applies local quality by ensuring uniformity in specific critical characteristics (maturity, plant height, ear height) that are essential for mechanical harvesting, while allowing variability in other non-critical traits. This targeted approach to uniformity maintains productivity requirements without compromising overall genetic diversity.
Solution Approach 2:
The patent performs preliminary selection for uniformity in harvesting-critical traits during the F1 and F2 generations, establishing uniform plant characteristics before the variety is released for mechanical harvesting. This preliminary action ensures that the variety will perform well with mechanical harvesting systems.
