“…This phenomenon has been attributed to the so called field resistance of Georgia Green (Culbreath et al, 1996(Culbreath et al, , 2000, in which, under experimental mechanical inoculation, no difference in susceptibility to TSWV was observed among several peanut cultivars that are less affected by disease under field conditions (Culbreath et al, 1994;Hoffmann et al, 1998). This phenomenon has been suggested to be related to plant factors that alter the insect behavior under field conditions, limiting TSWV transmission (Krishna Kumar, 1993).…”

“…There is the possibility that natural heterogeneity to susceptibility to thrips inoculation of TSWV exists in this breeding line. Evaluation of genotype resistance to TSWV in several crops has indicated the limitation of using only mechanical inoculation to evaluate resistance and susceptibility (Amin, 1985;Krishna Kumar et al, 1993;Culbreath et al, 1996;Wells et al, 2002).…”

-The objective of this work was to evaluate the reactions of three peanut breeding lines and ICGV 86388) to Tomato spotted wilt virus (TSWV) by mechanical and thrips inoculation, under greenhouse conditions, and compare them to the reactions of cultivars SunOleic, Georgia Green, and the breeding line C11-2-39. TSWV infection by mechanical inoculation was visually assessed using an index ranging from 0 (no symptoms) to 4 (apical death). Enzyme-linked immunosorbent assay was used to confirm TSWV infection from both mechanical and thrips inoculations. IC-10, IC-34, ICGV 86388, and C11-2-39 were more resistant than the cultivars SunOleic and Georgia Green based on mechanical inoculation. Upon thrips inoculation only IC-34 and ICGV-86388 were infected by TSWV, as demonstrated by reverse transcription polymerase chain reaction (RT-PCR), although no symptoms of infection were observed. The peanut breeding lines IC-10, IC-34, and ICGV 86388 show higher level of resistance to TSWV than cultivar Georgia Green considered a standard for TSWV resistance.Index terms: Arachis hypogaea, TSWV, mechanical transmission, thrips transmission. Avaliação de genótipos de amendoim em relação à resistência ao Tomato spotted wilt virus por meio de inoculação mecânica e por tripesResumo -O objetivo deste trabalho foi avaliar as reações das linhagens de amendoim IC-10, IC-34 e ICGV 86388 quanto à resistência ao Tomato spotted wilt virus (TSWV), por meio de inoculação mecânica e por tripes, em casa de vegetação, e compará-las às reações das cultivares SunOleic, Georgia Green e da linhagem C11-2-39. A infecção de TSWV após inoculação mecânica foi visualmente avaliada, utilizando-se escala de notas que variam de zero (sem sintomas) a quatro (morte apical). A análise pelo teste ELISA confirmou a infecção de TSWV em ambos os tipos de inoculação. As linhagens IC-10, IC-34, ICGV 86388 e C11-2-39 foram mais resistentes do que as cultivares SunOleic e Georgia Green, com base nos resultados da inoculação mecânica. Em relação à inoculação por tripes, apenas IC-34 e ICGV 86388 foram infectadas por TSWV, conforme demonstrado pela reação em cadeia da polimerase com transcrição reversa (RT-PCR), embora nenhum sintoma de infecção tenha sido observado. As linhagens IC-10, IC-34 e ICGV 86388 mostram maior resistência ao vírus, quando comparadas à Georgia Green, considerada padrão de resistência ao TSWV.Termos para indexação: Arachis hypogaea, TSWV, transmissão mecânica, transmissão por tripes.

“…Over 1000 plant species, both dicots and monocots in more than 80 plant families are susceptible to TSWV (Momol et al 2002). TSWV can be transmitted in a persistent, circulative manner by at least nine thrips species (Krishna-Kumar et al 1993;Johnson et al 1995;Nagata et al 2000). In a previous study, Thrips tabaci Lindeman and Frankliniella intonsa Trybom were the species found in tomato fields in Samsun in 2002 and 2003 growing seasons and 42% of tomato crops were lost due to TSWV infection in the region (Sevik, unpublished data).…”

To detect viruses infecting tomatoes and determine their incidences, surveys were conducted in 31 fields in Samsun province from May to August in 2002 and 2003. Tomato mosaic virus (ToMV), Tomato spotted wilt virus (TSWV), Potato virus X (PVX) and Cucumber mosaic virus (CMV) were detected in tomatoes after analysing 186 samples by enzyme-linked immunosorbent assay. ToMV, TSWV, PVX and CMV were detected 52.1, 12.9, 10.7 and 6.9% of the samples tested, respectively. Thirty samples (16.1%) were found to be mixed infected with these viruses. The most widespread and predominant virus (ToMV) also occurred in mixed infections with TSWV (6.4%), PVX (4.9%) and CMV (3.2%) in our study.

“…TSWV is known to cause an average loss of yield of 1 billion dollars each year and is one of the most intensively studied plant viruses due to the future economic importance of TSWV. TSWV is large geographically widespread over the tomato cultivated lands and a large series of hosts, thus resulting in serious economic losses ( German et al, 1992 , Krishna Kumar et al, 1993 , Mumford et al, 1996 ). The disease may result in 60–100% yield loss ( Rosellό et al, 1996 ).…”

The tomato as both a fresh consumption and industrial product is one of the most profitable vegetables and has a large cultivation area in the world. Parallel to intense production activities, Tomato Spotted Wilt Virus (TSWV), like viral diseases, results in significant economic losses every year. Use of resistant cultivars is the most efficient and environmental-friendly method of fighting against these diseases. This study was conducted to develop new tomato genetic resources resistant to TSWV because of the Sw-5 resistance breaking (RB) isolates that were determined in tomato cultivation areas. In this study, a total of 40 tomato materials including 15 lines, 9 commercial varieties and 16 wild genotypes were by tested with molecular and biological testing methods. Mechanical inoculation method was used for biological testing and SCAR marker was used in molecular analysis. S. penellii , S. chmielewski , S. habrochaites , S. peruvianum and S. sitiens , LA0716, LA1028, LA1777, LA2744 and LA4110 genotypes were found as resistant against breaking isolates of Tomato Spotted Wilt Virus. These genotypes may be a good resistance source for the future breeding studies in tomato.
