Maize Inbred 1PUFT30 Trait Introgression via Backcross Conversion
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 single variety that is agronomically sound across different conditions and environments.
Innovation Solution
A novel maize variety, 1PUFT30, is developed through careful breeding and selection, incorporating traits like male sterility, disease resistance, and drought tolerance, achieved through backcross conversion, genetic manipulation, and transformation, allowing for the creation of stable, high-yielding hybrids with improved agronomic characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop new maize varieties, then desirable traits can be combined in a single variety, but the development process takes six to twelve years making it time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-establishing inbred lines with desirable traits through backcross conversion and genetic manipulation before the final hybrid development. This allows the breeding program to start with pre-selected genetic material that already possesses target traits, reducing the overall development time from six to twelve years to a more efficient timeline while maintaining reliable combination of traits.
Solution Approach 2:
The patent uses inbred lines as intermediaries between the base germplasm and the final hybrid varieties. These inbred lines serve as mediators that carry desirable traits through backcross conversion and genetic manipulation, allowing complex trait combinations to be achieved more efficiently without requiring direct multi-year breeding from scratch.
2Productivity
If multiple desirable traits are combined in a single variety, then agronomic performance improves, but the complexity of achieving and maintaining these traits increases
Solution Approach 1:
The patent applies segmentation by dividing the complex breeding program into distinct phases: developing base inbred lines with specific traits, performing backcross conversion to introduce additional traits, and finally creating hybrid varieties. This segmentation allows each trait combination to be managed and optimized separately, reducing the overall complexity of achieving multiple desirable traits simultaneously.
Solution Approach 2:
The patent utilizes parameter changes through genetic manipulation and transformation techniques to modify specific genetic parameters (genes, chromosomes, or genomes) to introduce desirable traits. By changing genetic parameters rather than relying solely on traditional phenotypic selection, the breeding program can more precisely control and combine multiple traits while managing complexity through molecular-level precision.
3Reliability
If new varieties are developed with improved traits, then agronomic soundness and yield stability are enhanced, but the development process remains lengthy
Solution Approach 1:
The patent applies continuity of useful action by implementing continuous backcross conversion and genetic manipulation processes that operate parallel to traditional breeding cycles. Rather than sequential one-year steps, the program maintains continuous trait introduction and stabilization through overlapping breeding seasons, reducing the overall breeding cycle duration while preserving agronomic soundness through ongoing selection and testing.
