Abstract

Apparatus, methods, and systems for high throughput, useful sampling of seed, wherein viability is optionally maintained, are disclosed. Seed from one generation in a plant advancement experiment is individually sampled by removal and collection of tissue from the seed. The tissue is then processed to derive one or more biochemical, genetic, or phenotypic characteristic of the seed before a decision is made whether to utilize that seed further in a plant advancement experiment or other plant research and development. In some embodiments of the method, the sampling is controlled to remove a useful amount of tissue for analytical purposes without significant effect on viability potential of the sampled seed. In some embodiments, the sampling is controlled to deter contamination of the sample. In some embodiments, the seed is automatically positioned and oriented to facilitate efficient and accurate sampling.

Claims

1. A method of sampling seed comprising:

applying a magnetic substance to a particular location on a seed corresponding to a desired pre-determined orientation of the seed;

automatically positioning the seed in the pre-determined orientation by influence of a magnetic field;

removing a measurable sample from the seed.

2. The method of claim 1, wherein the removal of the measurable sample from the seed while in the pre-determined orientation does not cause a significant reduction to germination potential of the seed.

3. The method of claim 1 wherein the step of automatically positioning the seed in a pre-determined orientation comprises:

magnetically attracting the magnetically active substance in a manner related to the pre-determined orientation.

4. The method of claim 1 wherein the seed is corn seed.

5. The method of claim 3 wherein the seed is corn seed and the particular location on the seed is the crown of the seed.

6. The method of claim 1 further comprising automatically positioning a plurality of seed in the pre-determined orientation for high throughput processing of plural seed by influence of the magnetic field.

7. A method of sampling seed comprising:

applying a magnetically active substance to a particular location on a seed corresponding to a desired pre-determined orientation of the seed;

magnetically attracting the magnetically active substance on the seed to automatically position the seed in the desired pre-determined orientation; and

removing a measurable sample from the seed while being retained in the desired pre-determined orientation.

8. The method claim 7 wherein the particular location on the seed where the magnetically active substance is applied is a single location on the seed independent of other locations on the seed.

9. The method of claim 8 wherein placement of the magnetically active substance at the single location on the seed is based on the desired orientation and position of the seed for facilitating sampling.

10. The method of claim 7 wherein the particular location on the seed corresponding with the desired pre-determined orientation is the crown of the seed.

11. The method of claim 7 wherein the magnetically active substance is applied before removing a measurable sample from the seed.

12. The method of claim 7 wherein the pre-determined orientation of the seed corresponds with the step of removing a measurable sample from the seed.

13. The method of claim 7 wherein the magnetically attracting step comprises subjecting the magnetically active substance to the influence of a magnetic field for automatically orienting the seed in the desired pre-determined orientation.

14. A method of sampling seed comprising:

identifying a single location on a seed corresponding to a pre-determined orientation of the seed for facilitating sampling;

applying a magnetically active substance to the single location on the seed before sampling;

subjecting the seed to influence of a magnetic field at a position corresponding with the step of sampling;

attracting the magnetically active substance to automatically position and orient the seed in the pre-determined orientation; and

removing a measurable sample from the seed.

15. The method of claim 14 wherein the single location on the seed corresponding with the desired pre-determined orientation is the crown of the seed.

16. The method of claim 14 wherein the single location on the seed where the magnetically active substance is applied is independent of other locations on the seed to allow orienting and positioning of the seed to correspond with the pre-determined orientation.

17. The method of claim 14 wherein the pre-determined orientation of the seed resulting from placement the magnetically active substance corresponds with a location on the seed suited for facilitating removal of the measurable sample.
