Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plant breeding methods face challenges in developing uniform and stable melon varieties with desirable traits such as herbicide tolerance, insect resistance, and disease resistance, as they often result in unpredictable performance due to genetic non-uniformity in hybrid plants.
Innovation Solution
The development of the melon line HAR-DV15-4299MO, which involves creating a homozygous inbred line with specific genetic loci modifications through backcrossing or genetic engineering techniques, ensuring uniformity and stability by introducing traits like herbicide tolerance, insect resistance, and disease resistance, and producing a homogeneous seed population.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional breeding methods are used to develop melon varieties, then genetic diversity is maintained, but uniformity and predictability of hybrid performance deteriorate
Solution Approach 1:
The patent applies preliminary action by developing homozygous inbred parent lines through multiple generations of self-pollination and selection before crossing. This preliminary homozygosity ensures that when hybrids are produced, they will be uniform and predictable in performance, resolving the contradiction between maintaining genetic diversity and achieving uniformity.
Solution Approach 2:
The patent changes the genetic parameter of homozygosity in parent lines through systematic self-pollination over multiple generations. By increasing homozygosity from heterozygous to homozygous state, the patent ensures uniform hybrid performance while maintaining the ability to introduce desirable traits through controlled crosses.
2Adaptability or versatility
If multiple desirable traits are combined in breeding programs, then variety improvement is achieved, but breeding program complexity increases
Solution Approach 1:
The patent segments the breeding program into distinct phases: developing homozygous inbred lines, evaluating them for specific desirable traits, and then crossing selected lines to combine traits. This segmentation manages complexity by breaking down the multi-trait breeding process into controlled, sequential steps rather than attempting to manage all traits simultaneously.
Solution Approach 2:
The patent applies local quality by selecting parent lines that each excel in specific desirable traits (e.g., one parent for disease resistance, another for yield). By assigning different trait strengths to different parent lines, the patent efficiently combines multiple desirable traits in the hybrid while managing breeding program complexity through targeted selection.
3Stability of the object's composition
If homozygous inbred lines are developed through self-pollination, then uniformity is achieved, but time required for breeding increases
Solution Approach 1:
The patent applies self-service by using self-pollination to naturally produce homozygous inbred lines. The plants themselves perform the pollination function without requiring external intervention, efficiently achieving homozygosity through their own reproductive process over multiple generations, thus managing the time requirement for developing uniform lines.
4Manufacturing precision
If genetic engineering techniques are used to introduce traits, then precision of trait introduction is improved, but regulatory and public acceptance challenges increase
Solution Approach 1:
The patent uses conventional breeding methods as an intermediary approach between traditional random mutation and direct genetic engineering. By using controlled crosses and selection, the patent achieves precise trait introduction through natural genetic recombination, avoiding the regulatory and public acceptance issues associated with transgenic methods while maintaining precision through systematic selection.
