Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current crop breeding methods face challenges in developing uniform, high-yielding bean varieties with desirable traits such as resistance to insects, diseases, and environmental stress, as they often result in unpredictable performance due to genetic non-uniformity in hybrid plants.
Innovation Solution
The development of the bean line SVGV2089, which is homozygous and uniform, incorporating specific genetic loci for traits like herbicide tolerance, insect resistance, and disease resistance through backcrossing and genetic engineering techniques, ensuring consistent performance across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination is used to combine desirable traits from different plant varieties, then genetic diversity and trait variety are improved, but genetic uniformity and performance predictability deteriorate
Solution Approach 1:
The breeding program segments the development process into distinct phases: first developing uniform inbred lines through self-pollination, then crossing these standardized lines to create predictable F1 hybrids. This segmentation allows each phase to optimize for its specific goal without compromising the other.
Solution Approach 2:
The patent changes the genetic parameter from heterozygous (cross-pollinated) to homozygous (inbred) state to achieve uniformity. By deliberately creating homozygous inbred lines first, then crossing them, the program transforms the genetic state to achieve both diversity in traits and uniformity in performance.
2Reliability
If self-pollination is used to develop uniform inbred lines, then genetic uniformity and performance consistency are improved, but genetic diversity and trait combination capability deteriorate
Solution Approach 1:
The program performs preliminary self-pollination to create uniform inbred lines before proceeding to crossing. This preliminary action establishes the homogeneous genetic foundation necessary for predictable hybrid performance, while the subsequent crossing restores genetic diversity for trait combination.
Solution Approach 2:
The breeding program maintains continuous useful action by cycling between self-pollination (for uniformity) and cross-pollination (for diversity). This continuous alternation ensures both genetic uniformity within lines and genetic diversity across the breeding population, resolving the contradiction between the two requirements.
3Stability of the object's composition
If multiple breeding generations are advanced to achieve homozygosity, then genetic uniformity is improved, but breeding time and development duration increase
Solution Approach 1:
The patent replaces the traditional mechanical/time-dependent method of achieving homozygosity through multiple generations of selfing with molecular marker technology. By using DNA markers to track and select for homozygosity, the program accelerates the process without requiring as many generations, thus reducing breeding time while maintaining genetic uniformity.
