Crop descriptors
Descriptors lists are targeted at farmers, curators, breeders, scientists and users managing crop genetic resources collections.

Bioversity Technical Bulletin No. 13: Developing crop descriptor lists, Guidelines for developers (0.9 MB)
The guidelines have been produced based on experience gained from a wide range of crop studies and collaboration with many scientists, national programmes and crop networks.
These guidelines provide background information, set objectives and give insights into the structure, elements and methodology used by Bioversity to develop descriptor lists. They also provide a step-by-step checklist for defining characterization and evaluation descriptors, which can serve as a quick reference guide when developing new descriptor lists. Bioversity is thankful for the scientific advice and suggestions contributed by many scientists during the development of these guidelines.

Descriptors for Barley (Hordeum vulgare L.) (1.2 MB)
This descriptor list provides an international format and thereby produces a universally understood 'language' for plant genetic resources data. The adoption of this scheme for data encoding will produce a rapid, reliable, and efficient means for information storage, retrieval, and communication, and will assist with the utilization of germplasm.
It is recommended, therefore, that information should be produced by closely following the descriptor list with regard to: ordering and numbering descriptors; using the descriptors specified; and using the descriptors states recommended.

Key access and utilization descriptors for cassava genetic resources (0.1 MB)
This list consists of an initial set of characterization and evaluation descriptors for cassava utilization.
This key set of strategic descriptors, together with passport data, will become the basis for the global accession-level information system being developed by the Bioversity-led project, Global Information on Germplasm Accessions (GIGA). It will facilitate access to and utilization of cassava accessions held in genebanks and does not preclude the addition of further descriptors, should data subsequently become available.

The Grass Descriptor List was initially developed by a sub-committee from the Commission of the European Communities' (CEC) Programme Committee for Plant Disease Resistance Breeding and the Use of Genebanks. The final list combines experience from National List Descriptors, UPOV (International Union for the Protection of New Varieties of Plants) Descriptor Lists and was produced with advice and according to the International Board for Plant Genetic Resources standard format.

Descriptors for Maize (0.5 MB)
In 1980 IBPGR published a minimal list of descriptors for maize (Zea mays L.) following the third meeting of the IBPGR Maize Advisory Committee. This list was revised by IBPGR and CIMMYT in consultation with Cher experts (see Appendix). Descriptor numbers from the 1980 list were cross-referenced and are enclosed in parentheses following the descriptor in the revised list.

Descriptors for wild and cultivated Rice (Oryza spp.) (1.2 MB)
'Descriptors for wild and cultivated rice (Oryza spp.)' is a revision of the original IBPGR and IRRI publication 'Descriptors for rice (Oryza sativa L.)'

These very useful tools for standardised description of crop plants. I found that of cowpea to be very impressive

Dear Mr Ishiyaku,
You should use UPOV Technical Guidelines for DUS tests, taking into consideration the asterisked characteristics,

Would like to know if somebody are working on the development of descriptors for the fruit tree species - Psidium guajava and Syzygium cumini?
