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:

a. automatically positioning the seed in a pre-determined orientation;

b. removing a measurable sample from the seed.

2. The method of claim 1, wherein the removal of the measurable sample from the seed 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 predetermined orientation comprises:

i. applying a magnetically active substance to a location on the seed related to the pre-determined orientation;

ii. 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 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.

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

i. mechanically restraining the seed in the pre-determined orientation.

8. An apparatus for sampling one or more seed comprising:

a. a means to position a seed;

b. a means to orient the seed in a pre-determined orientation when the seed is positioned;

c. a means to separate a sample of the seed from the remainder of the seed when the seed is in position and pre-determined orientation.

9. The apparatus of claim 8 wherein the means to position the seed comprises a magnet and the means to orient the seed comprises a magnetically active substance or component on the seed.

10. The apparatus of claim 8 wherein the means to position and the means to orient the seed comprises a receiver having a geometry which mechanically restrains the seed in the position and predetermined orientation.

11. The apparatus of claim 8 wherein the means to separate comprises:

a. a laser beam;

b. a cutting edge;

c. a drill;

or

d. an abrasive surface.

12. The apparatus of claim 8 further comprising a container to collect each sample and a container to collect each sampled seed.

13. A method of sampling a seed comprising:

a. separating a sample from the remainder of a seed, the separating comprising one or more of;

i. without significantly affecting germination potential of the seed;

ii. providing a useful amount of sample;

iii. providing a sample from a desired location of the seed;

iv. minimizing risk of contamination of the sample; and

v. producing the sample at a relatively high throughput rate;

b. translating the sample to a pre-determined location for further use, the translating comprising one or more of;

i. minimizing risk of contamination of the sample;

ii. moving the sample at a relatively high throughput rate; and

iii. tracking the sample.

14. The method of claim 13 wherein translating the sample comprises one or more of:

a. suction;

b. pressurized air;

c. automated actuators;

d. mechanical apparatus;

e. gravity;

f. on a substrate.

15. The method of claim 13 wherein the pre-determined position of the sample is correlated to other samples.

16. A method of sampling seed tissue from individual seed comprising:

a. separating a relatively small portion of the seed from the remainder of the seed;

b. the separating step adapted to;

i. be non-lethal to the remainder of the seed; and

ii. provide a relatively measurable sample of the seed.

17. The method of claim 16 wherein the step of separating comprises one of:

a. cutting;

b. drilling;

or

c. sanding.

18. The method of claim 16 further comprising collecting the sample to deter contamination of a sample.

19. The method of claim 18 wherein the step of deterring contamination of samples comprises collecting each sample by:

b. vacuum;

or

c. adherence to a carrier.

20. The method of claim 16 further comprising positioning and orienting the seed prior to separation of the sample by:

b. holding the seed with a tool;

c. retaining the seed by properties of a surface;

or

d. holding the seed by magnetic attraction, wherein a magnetically active material or substance has previously been applied to a position on the seed correlated to desired orientation of the seed.

21. The method of claim 16 further comprising indexing one or both of the sample and the seed to an indexing system.

22. The method of claim 16 further comprising using the sample in an application comprising biochemical, genetic, or phenotypic testing.
