Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alfalfa breeding methods are time-consuming and unpredictable, requiring extensive research and effort to develop agronomically superior varieties due to the autotetraploid genome and self-incompatibility of alfalfa, leading to inbreeding depression and difficulty in predicting final varieties.
Innovation Solution
Development of the alfalfa variety R0415C4156, which is resistant to multiple pests and diseases, and can be propagated through crossing and vegetative methods, allowing for the production of stable, high-yielding alfalfa strains and varieties suitable for specific regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional alfalfa breeding methods are used, then agronomically superior varieties can be developed, but the process is time-consuming and unpredictable due to autotetraploid genome and self-incompatibility
Solution Approach 1:
The patent applies preliminary action by creating a stable synthetic population through controlled mass crossing of selected parents before the actual breeding cycle. This pre-establishes a genetically stabilized foundation that reduces unpredictability and shortens subsequent breeding cycles, as the population already possesses improved traits without requiring extensive time for trait stabilization.
Solution Approach 2:
The patent utilizes parameter changes by shifting from traditional incremental selection to a mass crossing approach that fundamentally alters the genetic composition parameters. By creating a synthetic population with specific genetic frequencies through controlled crossing, the method changes the breeding parameters to achieve both speed and reliability simultaneously.
2Productivity
If mass crossing of selected parents is performed to create synthetic population, then breeding time is reduced and stability is improved, but the complexity of managing and tracking genetic composition increases
Solution Approach 1:
The patent applies the taking out principle by extracting and isolating specific genetic traits and parents that contribute to desired characteristics. By identifying and separating useful genetic components from the overall population, the method simplifies the management of synthetic populations while maintaining high productivity through targeted mass crossing of selected parents.
