Abstract: -The objectives of this work were to evaluate two greenhouse screening methods for sudden death syndrome (SDS) and to determine which one is best correlated with fi eld resistance of soybean genotypes. The evaluations were done with three sets of genotypes that were classifi ed as partially resistant, intermediate, and susceptible to SDS based on previous fi eld evaluations. These three sets were independently evaluated for greenhouse SDS reactions using cone and tray inoculation methods. Plants were infected … Show more

“…These include dip inoculation of sprouted seed in F. virguliforme spore suspension and planting in greenhouse mix [80,81,85], temperature-controlled water bath method [38], exposing cut stem to cell free culture filtrate [42], molecular marker-assisted breeding for resistance [60], toothpick inoculation and soil infestation methods [111], planting seeds in a mixture of 1 part inoculum with 20 part soil [64], using cones filled with steam-treated soil mix (2:1 sand: soil) and topped with 3 g of fungus infested white sorghum grains [25]. Navi and Yang (unpublished), modified greenhouse screening technique [80,81,85] to identify resistance sources in germplasm and explore efficacy tests of seed treatments with biocontrol agents (BCA) and or chemicals against SDS (Fig.…”

“…Quando são testados em casa de vegetação, as médias de forma geral são similares para genótipos de diferentes ciclos de maturação (Farias Neto et al, 2008). Entretanto, os testes de campo, especialmente em fases finais de programas de melhoramento, refletem mais a realidade do que os testes realizados em casa de vegetação (Farias Neto et al, 2008). Os cultivares BRS Tuiuiú e P98R91 apresentaram os maiores índices, respectivamente.…”

“…Resistance is quantitative (Meksem et al, 1999;Iqbal et al, 2001;Njiti et al, 2002;Farias Neto et al, 2007), producing consistent symptoms in the field is very difficult (Scherm and Yang, 1996), and although more consistent results can be obtained in the greenhouse, those data can be different from those collected in field trials Farias Neto et al, 2008). For example, we have evaluation data for over 6800 accessions for resistance to Fusarium virguliforme, which causes sudden death syndrome (SDS).…”
