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 AN1081, which involves genetic manipulation and transformation to incorporate traits like male sterility, disease resistance, and improved agronomic characteristics through backcross conversion and cytoplasmic-nuclear interactions, along with specific breeding processes to produce hybrid maize seeds and plants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional maize breeding processes are used to combine desirable traits, then disease resistance and yield improvement can be achieved, but the development process takes six to twelve years and is highly time-consuming
Solution Approach 1:
The patent utilizes pre-established inbred lines with known genetic characteristics and pre-characterized traits. By starting with genetically defined parent lines that already possess desired characteristics, the breeding process eliminates the need for lengthy trait discovery and selection phases, significantly reducing development time while maintaining reliability of disease resistance and yield traits
2Productivity
If multiple desirable traits are combined in a single variety, then agronomic performance and yield are improved, but the breeding process becomes more complex and difficult to manage
Solution Approach 1:
The patent divides the complex breeding process into distinct segments: selecting parent inbreds with specific traits, performing controlled crosses, evaluating F1 hybrids for desired trait combinations, and systematically advancing superior lines. This segmentation of the breeding process into manageable stages reduces overall complexity while enabling the combination of multiple desirable traits for improved yield and agronomic performance
3Stability of the object's composition
If genetic stability and uniformity are maintained through traditional inbreeding, then variety stability is achieved, but the process requires multiple generations of selfing and is time-consuming
Solution Approach 1:
The patent employs molecular marker technology to copy and track specific genetic segments associated with desired traits through generations. By using DNA markers to monitor inheritance, the program can verify genetic stability and uniformity without requiring multiple generations of phenotypic evaluation, significantly reducing the time needed to establish genetically stable varieties while maintaining composition consistency
