A greenhouse study in the late 1990s used a set of TSWV isolates from Australia to show that resistance breaking (RB) strains of TSWV could be induced by the selection pressure of using tomato varieties with Sw-5 resistance.6 The first detection of resistance breaking of Sw-5 in the field was reported from South Africa back in 1993, but that RB strain of TSWV did not become established and did not spread.

The TSWV isolates collected from symptomatic plants could infect and cause symptoms on all of the Sw-5 resistant tomato varieties tested in greenhouse trials, verifying the existence of RB TSWV strains in California.9, The emergence of RB isolates of TSWV in many locations worldwide most likely is the result of the continuous, widespread use of tomato varieties with Sw-5 resistance.5 At least some of the RB isolates of TSWV studied so far appear to have lower environmental fitness when compared to non-RB strains, because the percentage of TSWV isolates that are able to break Sw-5 resistance declines over time in a region when tomato varieties with Sw-5 resistance are not grown consistently in that region.5 For example, tomato growers in Hawaii stopped using varieties with Sw-5 resistance to TSWV because that form of resistance was no longer effective due to the presence of RB strains of TSWV. The symptoms of TEV and PVY can be confused with TMV. All plants in an accession were initially screened for resistance to TSWV using isolate 85–9 from Arkansas. Plant Dis.

Traditionally, peanut breeders select resistant plants in the field under natural conditions. 3 Falk, B. The use of genes that convey partial resistance could also be useful, as this type of resistance tends to be longer lasting.4,5, Because RB strains of TSWV appear to be less fit than wildtype strains, the use of “Sw-5 rest periods”, times in which Sw-5 resistant tomato varieties are not grown in a region, could be used to lower the proportion of RB strains and restore the effectiveness of the Sw-5 resistance gene.
