Abstract

The author makes a proposal on the use of a code system elaborated for the major test plants (hosts, non-hosts) of plant viruses as well as for diagnostically important cultivars and hybrids by adapting and using the Weed Science Society of America (WSSA) and Weed Science Society of Japan (WSSJ) approved computer codes; and also suggests the establishment of a data base. The code system covers the virus acronyms (e.g., TMV for tobacco mosaic virus), the virus family/groups and subgroups (e.g., TOBAMO for tobacco mosaic virus group; or BROMO for brome mosaic virus group, etc.), the hosts and non-hosts (five letter abbreviations; e.g., AGRIT for Agropyron intermedium), the cultivars and hybrids (three letter codes; e.g., SAM for cultivar Samsun of Nicotiana tabacum, or GTC for hybrid of Nicotiana glutinosa x Nicotiana clevelandii), the plant families (three letter codes; e. g., AIZ for Aizoaceae) and the host characters (2-4 letter abbreviations; e.g., AH for assay host, DH for diagnostic host, PH for propagation host). With these abbreviations used a code system can be written down: e.g., AILV - NEPO - NIOTA - WHB - DH - SOL, which expresses that the artichoke Italian latent Nepovirus (AILV - NEPO) has the Nicotiana tabacum (NIOTA) White Burley cultivar (WHB) as host, which is a diagnostic host (DH) for the virus, and belongs to the family Solanaceae (SOL).
