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 stable and agronomically sound manner.
Innovation Solution
The introduction of the novel maize variety PH47JV, which involves crossing and genetic manipulation to introduce traits like male sterility, disease resistance, and improved agronomic characteristics, using backcross conversion and transformation techniques, along with specific breeding practices to produce stable and high-yielding maize plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding methods are used to combine desirable traits, then the variety achieves stability and agronomic soundness, but the development process takes six to twelve years
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing inbred line PH47JV with specific desirable traits (disease resistance, yield potential, agronomic characteristics) before hybrid development. This preliminary characterization and selection of parent lines with complementary traits accelerates the breeding process by reducing the need for extensive multi-year field testing and selection cycles that traditionally take 6-12 years.
2Productivity
If multiple desirable traits are combined in a single variety, then the variety achieves maximal yield across different conditions, but the breeding process becomes more complex and time-consuming
Solution Approach 1:
The patent applies segmentation by dividing the complex trait combination process into manageable components: selecting specific inbred lines (PH47JV and compatible partners) that already possess certain desirable traits, then combining them in controlled hybrid crosses. This segmentation of the breeding process into discrete parental selection and hybridization steps simplifies the overall complexity while achieving multi-trait combinations for maximal yield across different environmental conditions.
3Stability of the object's composition
If traditional breeding methods are used to introduce new traits, then the variety achieves genetic stability, but the process requires six to twelve years from first cross to finished seed
Solution Approach 1:
The patent applies parameter changes by utilizing controlled hybridization parameters and selective breeding strategies with inbred line PH47JV to accelerate genetic stabilization. By optimizing cross-compatibility parameters, selection criteria, and generation advancement timing, the process achieves genetic stability more rapidly than traditional methods, reducing the 6-12 year timeline while maintaining variety integrity and stability.
