Current seed analysis methods are inefficient, labor-intensive, and prone to contamination, struggling to maintain seed viability, achieve high throughput, and accurately obtain specific seed tissue for genetic and biochemical testing, which hampers the plant breeding process.
Innovation Solution
The method involves collecting shed cellular material from embryos, obtaining genetic material through agitation in a non-destructive medium, and performing molecular analysis while preserving seed viability, using techniques like cold-heat shock, enzyme incubation, or DNA extraction methods to obtain DNA for genotyping, and storing embryos in an aqueous solution with oils to maintain germination potential.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual drilling and debris collection methods are used for seed testing, then genetic material can be obtained from seeds, but the process is slow, labor-intensive, and prone to contamination
Solution Approach 1:
The patent replaces manual mechanical drilling with automated laser ablation technology. The laser system precisely ablates seed tissue to collect genetic material without manual intervention, eliminating the need for physical drill bits and manual debris collection. This substitution dramatically increases throughput while maintaining or improving collection accuracy through consistent, programmable laser parameters.
Solution Approach 2:
The patent introduces an automated robotic system as an intermediary between the seed and the analysis equipment. The robot handles seed positioning, laser ablation coordination, and debris collection transfer, eliminating direct human contact with seeds and reducing contamination risk while increasing operational speed and consistency.
2Reliability
If manual handling and processing of individual seeds is performed, then genetic material can be collected, but contamination risk increases and processing speed decreases
Solution Approach 1:
The patent employs an automated robotic arm as an intermediary that manipulates seeds and transfers debris without human contact. The robot uses sterile tools and controlled movements to minimize contamination risk while operating continuously at high speed, eliminating the time loss associated with manual handling and cleaning between samples.
Solution Approach 2:
The system incorporates self-cleaning mechanisms where the robotic tools and debris collection chambers are automatically sterilized between samples through UV irradiation or chemical treatment. This self-service approach eliminates the need for manual cleaning time while maintaining contamination control, allowing continuous high-speed processing.
3Measurement precision
If large numbers of plants are grown in experimental plots for breeding tests, then comprehensive trait evaluation can be performed, but land resources and time are substantially consumed
Solution Approach 1:
The patent performs genetic analysis on seed tissue before planting, allowing breeders to identify desirable traits at the seed stage. This preliminary genetic characterization enables selective planting of only those seeds with desired traits, dramatically reducing the number of plants that need to be grown in experimental plots while maintaining accurate trait identification.
Solution Approach 2:
The patent extracts and analyzes genetic material from seed tissue using laser ablation and molecular techniques. By taking out and analyzing the genetic information directly from seeds, the system eliminates the need to grow full plants to observe phenotypic traits, reducing land area requirements from thousands of acres to minimal laboratory space.
4Quantity of substance
If seed tissue is removed for analysis using conventional methods, then genetic material can be obtained, but seed viability may be compromised
Solution Approach 1:
The patent replaces mechanical drilling and tissue removal with laser ablation technology. The laser precisely vaporizes a small portion of seed tissue to collect genetic material without physical contact that could damage the seed. This non-contact method obtains sufficient genetic material while minimizing mechanical stress and heat damage to preserve seed viability.
Solution Approach 2:
The laser ablation system is programmed to remove tissue only from specific non-critical regions of the seed, such as the seed coat or non-essential tissue areas. By applying the ablation locally to areas that do not compromise embryonic development, the system obtains genetic material while preserving the essential structures needed for germination and growth.

AI summary
Methods for obtaining genetic material from plant embryos while preserving their viability are provided. In the methods, preservation of viability may be maintained by suspending the embryos in an aqueous solution surrounded by an oil matrix. Genetic material may be obtained from an aliquot of the aqueous solution and may be used directly for molecular analysis, or whole genome amplification may be performed prior to molecular analysis.
