Automated seed sampler and methods of sampling, testing and bulking seeds
An automated seed sampler includes a sampling station; a sampler for removing material from a seed in the sampling station; a seed conveyer for conveying the seed from the sampling station to a compartment in a seed tray; and a conveyor for conveying the material removed from the seed to a corresponding compartment in a sample tray. The method of the present invention comprises feeding seeds individually to a sampling station, removing a sample from the seed in the sampling station; conveying the sample to a compartment in a sample tray, and conveying the seed to a corresponding compartment in a seed tray. The samples can be tested, and the seeds can be sorted according to the results of the testing of their corresponding samples.
1. A method of bulking seeds in a population comprising:
(a) taking a sample from each seed in the population, wherein the sample includes a portion of said each seed;
(b) conveying each seed and the sample from each seed to separate locations of known relationship;
(c) testing each sample for a desired property; and
(d) thereafter separating the seeds based upon the results of the testing from each seed.
2. The method according to claim 1 further comprising cultivating plants from the seeds that exhibited the desired property; harvesting seeds from the cultivated plants; and repeating steps (a)-(d).
3. The method according to claim 2 further comprising feeding each seed to a sampling station; removing the portion of said each seed at the sampling station; and transporting the seed and the sample from the seed to separate locations of known relationship.
4. The method according to claim 3 wherein each sample is pneumatically transported from the sample station to at least one compartment in a sample tray, and wherein each seed is pneumatically conveyed from the sample station to a corresponding compartment in a separate seed tray.
5. The method according to claim 3 wherein the step of removing a portion of the seed comprises scraping material from the seed to a depth of no more than about 3 millimeters.
6. The method according to claim 3 wherein the sample is transported in a tube made from a non-electrostatic material.
