Epidemics of spotted wilt, caused by tomato spotted wilt tospovirus, were monitored in field plots of advanced breeding lines of groundnut GA T-2846, F 84X9B-1-1-1-b3-B and F 84X1A-7-2-1-1-b2-B and in runner-type groundnut cultivars Georgia Browne, Southern Runner and Florunner in 1 location in 1993 and in 3 locations in 1994 in Georgia, USA. Across all tests, final incidence of spotted wilt and standardized areas under the disease progress curves were lower in the 3 breeding lines, Georgia Browne and Southern Runner compared with standard runner-type cultivar Florunner. With some exceptions, numbers of tobacco thrips (Frankliniella fusca), western flower thrips (F. occidentalis) and larvae of Frankliniella spp. were similar for all groundnut cultivars and breeding lines. There was no evidence that differences in disease progress among the 6 entries were due to differences in preference by thrips or to suitability for thrips reproduction. It is suggested that all 3 advanced breeding lines evaluated in this study represent potential tools for management of spotted wilt in groundnut production areas of the southeastern USA.
