Abstract

Curly top disease (CID) is one of the most economically important diseases of SUGAR BEET (Beta vulgaris L.) in IRAN. Resistant varieties have been used effectively for controlling CTD. In the present study, 50 accessions of SUGAR BEET GERMPLASM were evaluated for curly top RESISTANCE. A SUGAR BEET plant with typical symptoms of CTD was selected in Zarghan (Fars Province) and used as a source of beet curly top virus (BCTV) in inoculation experiments. Twenty one seedlings of each accsession were tested. Two young viruliferous leafhoppers (Circulifer haematoceps) were caged on each plant at two-leaf stage and allowed to feed for 5 days. The plants were rated for severity of curly top symptoms four and eight weeks after inoculation. Each inoculated plant was graded using a 0-5 scale (0, plants free of symptoms; 5, plants dying). Mean value of disease severity index (DSI) was computed for each accession tested. DSI values varied from 1.25 to 3.8. DSI range in 21, 22 and 7 accessions was 3 - 3.8, 2 - 3 and less than 2, respectively. F-20511, 16402-66, 13687-62, F-20510 and 13691-62 with DSI 1.25, 1.35, 1.5, 1.55 and 1.65, respectively, were considered the most resistant accessions and are recommended for further research in the field and incorporation in breeding programs. In most cases, DSI recorded after eight weeks was less than that recorded after four weeks, indicating general recovery tendency in some genetic materials. The rate of recovery varied among accessions and its possibility for selection program must be studied further.
