摘要:
A population of seeds wherein substantially all of the seeds in the population have a portion of seed tissue removed by an automated sampling system. Substantially all of the seeds in the population have the presence or absence of at least one transgene in common, and/or substantially all of the seeds in the population have a high recurrent parent allele frequency. The presence or absence of the at least one transgene in the seeds in the population and/or the recurrent parent allele frequency in the seeds in the population is determined by analyzing the portion of seed tissue removed from the seeds by the automated sampling system.

The present invention provides for novel methods to facilitate germplasm improvement activities through the use of high throughput, nondestructive sampling of seeds. A method for analyzing a population of haploid seeds generally includes providing a population of seeds comprising haploid seeds, removing tissue samples from a plurality of the seeds in the population using an automated seed sampler system while preserving the germination viability of the sampled seeds, and analyzing the tissue samples for the presence or absence of one or more characteristics indicative of at least one genetic or chemical trait.

The present invention provides for novel methods to facilitate germplasm improvement activities through the use of high throughput, nondestructive sampling of seeds. In one embodiment, a high-throughput, non-destructive method for analyzing individual seeds in a population of seeds comprises removing a sample from a plurality of seeds in the population while preserving the germination viability of the seed and analyzing the sample for the presence or absence of one or more characteristics of at least one genetic or chemical trait.

Controlling transient responses in power amplifiers may be accomplished in the following manner. Upon detecting an output power adjustment request, a reference level is accessed from memory, wherein the reference level is based on a previous output condition that is substantially equal to the requested output condition. From the reference level, a first response time is calculated and supplied to a control circuit of the power amplifier such that the power amplifier operates at a first gain level. When the first response time elapses, the power amplifier operates at a second gain level, where the first gain level is greater than the second gain level.

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.
摘要:
A seed sampling system is provided having an automated seed loading assembly including a seed bin and being operable to singulate seeds from a plurality of seeds within the seed bin. The system also includes an automated seed sampling assembly operable to remove tissue samples from the singulated seeds, and an automated seed transport assembly operable to transfer the singulated seeds from the seed loading assembly to the seed sampling assembly. The seed transport assembly includes multiple retention members. Each of the retention members is movable relative to the seed loading assembly and to the seed sampling assembly. The seed transport assembly is operable to position one of the multiple retention members adjacent to the seed loading assembly for engaging one of the singulated seeds, while positioning another of the retention members adjacent to the seed sampling assembly for presenting another of the singulated seeds to the seed sampling assembly.

An automated system for sampling seeds generally includes an automated sampler operable to remove a tissue sample from a seed, a seed tray configured to receive from the automated sampler the seed from which the tissue sample is removed, and a sample tray configured to receive the tissue sample removed from the seed. A table supports the seed tray and the sample tray, and an index mechanism is operable to move the table to bring the seed tray into position for receiving from the automated sampler the seed from which the tissue sample is removed, and to bring the sample tray into position for receiving the tissue sample removed from the seed.

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. And a method for bulking up a quantity of plant seed having a desired characteristic generally includes testing each seed for the desired characteristic, cultivating plants only from seeds which tested positive for the desired characteristic, recovering seed from the cultivated plants, and repeating the processes of testing, cultivating, and recovering seed for one or multiple generations.
