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 crop production and mechanical harvesting.
Innovation Solution
Development of a novel maize variety, PHE64, and processes for making it, including crossing with other maize plants, introgression of traits through backcross conversion and transformation, and production of hybrid seeds and plant parts with specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding is used to combine desirable traits, then resistance to diseases and insects, resistance to heat and drought, reducing the time to crop maturity, greater yield, and better agronomic quality can be achieved, but uniformity of plant characteristics such as germination, stand establishment, growth rate, maturity, plant height and ear height becomes difficult to maintain
Solution Approach 1:
The patent segments the complex breeding process into distinct stages: creating inbred lines with specific traits, then crossing them to produce hybrids. This segmentation allows systematic combination of desirable traits while maintaining uniformity through controlled breeding steps.
Solution Approach 2:
The patent merges multiple desirable traits into a single hybrid variety by crossing inbred lines that each possess specific traits. The hybrid combines resistance to diseases, insects, heat and drought, reduced maturity time, greater yield, and uniform plant characteristics in one integrated variety.
2Stability of the object's composition
If inbred lines are used to ensure uniformity, then mechanical harvesting can be efficiently performed, but genetic diversity and adaptability to different environments are reduced
Solution Approach 1:
The patent applies local quality by creating inbred lines with specific localized traits (disease resistance, drought tolerance, growth rate) and then combining them in hybrids. Each inbred line maintains uniformity for its specific function while the hybrid overall achieves both uniformity and genetic diversity.
Solution Approach 2:
The patent creates a composite genetic structure by combining multiple inbred lines with different genetic compositions into a hybrid. This composite approach maintains uniformity through controlled inbreeding while introducing genetic diversity through the combination of different inbred lines in the hybrid.
3Productivity
If crossing inbred lines to create hybrids is performed, then yield and vigor are improved through heterosis, but the complexity of breeding programs and time required for development increases
Solution Approach 1:
The patent applies preliminary action by first developing and testing multiple inbred lines with desired traits before creating the final hybrid. This preliminary development of component lines simplifies the overall breeding program by pre-establishing the genetic building blocks that can be systematically combined.
Solution Approach 2:
The patent uses copying through the repeated use of validated inbred lines as parents for multiple hybrid generations. Once inbred lines are developed and tested, they can be reused across different hybrid combinations, simplifying the breeding program complexity while maintaining high yield and vigor through heterosis.
