Germplasm Management System
Seed companies need to manage genetic resources over years, sometimes decades, with accurate traceability, genotype codification and genealogical relationships. The physical storage of these resources takes place in the company owned seed bank. In addition to this, information systems today enable to manage numerical records of the physical seeds.
Codification / Unicity
Mainly for traceability matters, it is a key point for breeders to have a unique name for any genetic resource which is used during a breeding program. The codification will often be a concatenation of short codes which are properties of the genotype material: species, material type, generation, source experiment…
A germplasm management system enables to store different types of data which are crucial to define the nature of the genotype material. It can be phenotypic data (traits, yield, precocity…), genotypic data (species, pedigree, parentage, material type, generation…), or miscellaneous data like attached files or pictures. Different views can be designed to display specific results related to a specific topic only.
Traceability / security
Any removal, update, or addition of genotype material can be traced. Each information system will have different levels of traceability as the rules to generate a record in the backup log is very configurable: a balance between data loss avoidance and reasonable amounts of data. Also, different user profiles can be created to ensure data confidentiality: read access, no access, read & write access…
Numerical identifiers have made possible the accurate parentage traceability between each record of a germplasm management system. This is the necessary basis for powerful interactive graphical representations which enable to display together genotype materials with very distant genealogical relationships.
Seed quantities/weight/thousand Kernel weight
In a germplasm management system, automatic computation can be done for seed bags weight, quantities and thousand Kernel weight. In fact, at some stages of a breeding program, the amount of seeds for some genetic resources might be quite limited. The germplasm management system can offer some features to have an efficient management of the available seeds.
Genotype inventory is the process where an operator will make a verification to match information system database records and existing genotype materials. Labels with bar codes can be printed and scanned to process the inventory. A similar process can be used to verify the accurate occurrence and sorting of individual bags of seed to prepare the sowing.
The genotype resources aim to be used into experiments, to collect phenotypic or other type of data. A germplasm management system can record the source experiment and destination experiment for each lot. This information can be relevant for the breeders as the identity of genotype material is very correlated with the type of experiment it was harvested from, or the one it will be used into.
In some ways, the core of the RnDExp software is its genotype STOCK (the name of the germplasm table in the software). Standard RnDExp experiments have a direct relationship with it, in a way that every genotype material which is used as a modality in an experiment takes its source in the RnDExp Stock. Every dataflow of the STOCK individuals is traced in a dedicated table, so that the breeder can have a virtual overview of each germplasm he is using in his program. Also, there are several features in the software which are genotype or genealogy based, and Doriane strongly heads its innovations on these.
