Lentil descriptors

Abstract

This descriptor list has been prepared in an IBPGR standard format following advice on descriptors and descriptor states arising from a meeting held at ICARDA on May 10-11 1982, and subsequently from crop experts throughout the world (see Appendix I). The IBPGR encourages the collection of data on the first four categories of this list; 1. Accession; 2. collection; 3. and 4. Characterization and preliminary evaluation. The IBPGR endorses The information in categories 1-4 is the minimum that ideally should be available for anyone's accession. Other descriptors are given in categories 5 onwards that will enable the simple encoding of further characterization and evaluation data which can serve as examples for the creation of additional descriptors in the IBPGR form by any user. Although the suggested coding should not be regarded as the definitive scheme, this format has the full backing of the rBPGR and is promoted worldwide. The descriptor list is given here provides an international format and thereby produces a universally understood 'language' for all plant genetic resources data. The adoption of this scheme for all data encoding. or at least the production of a transformation method to convert other schemes to the IBPGR format will produce a rapid, reliable and efficient means for information storage, retrieval and communication. This will greatly assist the utilization of germplasm throughout the international plant genetic resources network. It is recommended, therefore, that information should be produced by closely following this descriptor list with regard to: ordering and numbering descriptors; using the descriptor specified, and using the descriptor states recommended.
