Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beet breeding methods face challenges in identifying and developing genetically superior beet varieties due to the masking of true genotypic value by confounding plant traits and environmental factors, and in efficiently transferring desirable traits through breeding processes.
Innovation Solution
The development of the inbred beet line AZ10319, which allows for advanced breeding techniques such as backcrossing, recurrent selection, and genetic editing using methods like CRISPR, to introduce traits like herbicide tolerance, disease resistance, and enhanced nutritional quality, while maintaining the physiological and morphological characteristics of the parent line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional beet breeding methods are used, then breeding processes can be maintained with conventional techniques, but the ability to identify and develop genetically superior varieties is limited due to masking of true genotypic value by confounding plant traits and environmental factors
Solution Approach 1:
The patent extracts and removes the confounding effects of environmental factors and plant traits that mask true genotypic value. By using inbred lines with high genetic uniformity, the patent isolates the genetic component from environmental noise, enabling precise measurement of genotypic value without the interference of variable environmental conditions.
Solution Approach 2:
The patent changes the genetic parameter of the breeding material by using highly inbred lines with near-complete homozygosity. This parameter change from heterogeneous to homogeneous genetic material transforms the measurement environment, allowing true genotypic value to be expressed without masking effects.
2Productivity
If advanced breeding techniques such as backcrossing and genetic editing are implemented, then desirable traits can be introduced more efficiently, but the complexity of the breeding process increases
Solution Approach 1:
The patent performs preliminary action by creating highly inbred parent lines before initiating backcrossing or genetic editing programs. This preliminary inbreeding establishes a genetically uniform foundation that simplifies subsequent trait introduction, as the uniform genetic background reduces variability and makes selection more efficient.
Solution Approach 2:
The inbred line acts as an intermediary between the donor parent and the recurrent parent in backcrossing programs. The highly uniform genetic background of the inbred line mediates the transfer of desirable traits by providing a stable genetic framework that facilitates efficient selection and reduces the number of backcrosses needed.
3Measurement precision
If inbred lines with high genetic uniformity are used, then true genotypic value can be accurately assessed, but genetic variability for selection is reduced
Solution Approach 1:
The patent segments the breeding program into distinct phases: first using highly inbred lines for precise genotypic assessment and foundation establishment, then introducing genetic variability through controlled crosses with diverse parents. This segmentation allows each phase to optimize for its specific purpose without compromise.
Solution Approach 2:
The patent performs preliminary inbreeding to establish uniform parent lines before introducing genetic variability. This preliminary action creates a stable genetic foundation that enables accurate assessment, and subsequent controlled crossings reintroduce variability in a managed manner for selection purposes.
