Maize Inbred PH137K Trait Segmentation
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, PH137K, through a breeding process involving crossing inbred lines, self-pollination, and selection, resulting in a substantially homozygous line with improved traits such as resistance to various stresses and uniform plant characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional plant breeding methods are used to combine multiple desirable traits, then the complexity of the breeding process increases, but the ability to achieve uniformity and combine multiple traits (disease resistance, drought tolerance, etc.) is limited
Solution Approach 1:
The patent segments the breeding process into distinct phases: initial crossing of inbred lines, self-pollination over multiple generations, and systematic selection at each stage. This segmentation allows complex trait combination to be managed through structured, repeatable steps rather than uncontrolled traditional breeding
Solution Approach 2:
The patent performs preliminary actions by pre-selecting inbred lines with specific desirable traits before crossing, and by establishing uniform breeding protocols in advance. This preliminary preparation reduces the complexity of the overall breeding process while ensuring the combination of multiple traits is achieved systematically
2Productivity
If traditional breeding methods are used to develop new varieties, then the time required for variety development increases, but the achievement of desired trait combinations is possible
Solution Approach 1:
The patent maintains continuous useful action through uninterrupted self-pollination cycles and consistent selection pressure across multiple generations. This continuous breeding process accelerates variety development compared to traditional methods that may have intermittent selection or breeding pauses
Solution Approach 2:
The patent implements feedback mechanisms by evaluating plants at each generation for desired traits and using this information to guide subsequent selection and crossing decisions. This systematic feedback loop accelerates the development of varieties with combined desirable traits by learning from each breeding cycle
3Manufacturing precision
If inbred lines are used to achieve uniformity in plant characteristics, then the genetic diversity decreases, but the uniformity of germination, stand establishment, growth rate, and maturity is improved
Solution Approach 1:
The patent applies local quality by using different inbred lines with specific trait combinations for different breeding objectives. Each inbred line maintains its specialized genetic composition for particular traits, while the overall breeding program preserves genetic diversity through the use of multiple specialized lines rather than one homogeneous line
