Fusarium virguliforme, the soilborne fungus that causes sudden death syndrome (SDS), and Heterodera glycines, the soybean cyst nematode (SCN), are economically important pathogens that often occur concomitantly in Kansas soybean fields. To examine F. virguliforme and H. glycines interactions across multiple environments, four soybean genotypes with different levels of resistance to SDS and SCN were planted at three to four locations in northeastern Kansas in 2008 and 2009. Pathogen population densities were quantified at planting (Pi), midseason (Pm), and harvest (Pf). At harvest, SDS AUDPC, F. virguliforme root population densities, H. glycines reproductive factors (RF), and yield were determined. The performance of resistant (R) genotypes varied with environment and disease pressure, but SDS-R genotypes were associated with 36% greater yields than SDS-susceptible (S) genotypes in high SDS environments. Even moderate levels of SCN resistance reduced SDS disease severity in SDS-S genotypes. Negative correlations (P ≤ 0.05) were observed between yield and AUDPC, and yield and F. virguliforme root population densities. A regression model that combined both of these covariates explained 57% of the yield variation. Disease severity was positively correlated with H. glycines Pi, but negatively correlated with RF. The data emphasize the importance of combining SDS and SCN host resistance in fields with a history of both diseases. Accepted for publication 6 November 2013. Published 27 January 2014.

Lipo-chitooligosaccharides (LCOs) are signal molecules produced by plant root endosymbionts and have been identified, formulated, and marketed as growth-promoting adjuvants for soybean (Glycine max [L.] Merr.). Experiments were conducted under controlled environmental conditions to characterize the effects of foliar LCO applications on early symptom development of sudden death syndrome (SDS), caused by Fusarium virguliforme, and Sclerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum. Treatment factors for the SDS experiment included two soybean cultivars (Sloan and CH2105R2), two inoculation levels (noninoculated control and inoculated), and two LCO applications (control and foliar LCO application), whereas two experimental soybean lines (91-38 and 91-44) and two LCO applications (water control and foliar LCO application) were used in the SSR experiment. The LCO application did not significantly influence SDS root symptom severity or early-season growth characteristics. However, on the susceptible line (P = 0.01) and with LCO application (P = 0.03), significantly larger SSR lesions developed compared with the nontreated control and resistant line. These results suggest foliar-applied LCOs have a limited effect on early root symptom development caused by F. virguliforme but increase stem symptom development caused by S. sclerotiorum.

The ecology of the complex of soybean cyst nematode (SCN) and sudden death syndrome (SDS) of soybean was investigated under soybean monoculture in two field experiments from 2003 to 2007. Initially, susceptible soybean ‘Spencer’ was planted while inoculating Fusarium virguliforme into nonfumigated or preseason-fumigated plots (methyl bromide, MB, at 450 kg/ha), and SCN and SDS were monitored. In one field, SCN population densities declined in nonfumigated but increased in fumigated plots. After years of limited SDS in 2003 and 2004, SDS developed later in nonfumigated than fumigated plots. In 2006 in the greenhouse, nondisturbed or disturbed soil cores (10-cm diameter, 30-cm depth) from field plots received two two-level factors: (i) nonfumigated or fumigated (1,070 kg/ha MB); and (ii) noninoculated or inoculated with 9,000 second-stage juveniles of SCN. At harvest, nonfumigated cores from nonfumigated plots had fewer nematodes and less SDS regardless of disturbance or inoculation than the corresponding fumigated cores and any cores from fumigated plots. In the second field, SCN became detectable after 2003 during the monoculture in nonfumigated plots and lagged in fumigated plots; both treatments had low levels of SDS. Exploiting the suppressiveness of the first field could allow for biological control of SDS and SCN in soybean production.

Clark, W. D., Reyes-Valdes, M. H., Bond, J. and Kantartzi, S. K. 2013. Performance of LS97-1610בSpencer’ soybean recombinant inbred line population segregating for resistance to Fusarium virguliforme . Can. J. Plant Sci. 93: 1179–1185. Sudden death syndrome (SDS) is a devastating disease in soybean which is caused by Fusarium virguliforme. Sudden death syndrome resistance is a quantitative trait; therefore, development of resistant varieties requires understanding of complex genetics and environmental effect. In this study, we aimed to characterize 94 F5:8 recombinant inbred (RI) lines derived from a cross between a resistant line for SDS, LS97-1610 and a susceptible cultivar, ‘Spencer’ and to identify sources of resistance. The RI lines were evaluated for their relative resistance (RR) to SDS along with the parents in four different environments; two years (2009 and 2010) and two locations (Carbondale and Valmeyer, IL). Analysis of variance revealed significant interactions between genotype and environment in each year of experimentation and in 2-yr combined data. Broad-sense heritability was estimated by ANOVA results, and it was moderate (61%). These results indicate that SDS resistance is partially unpredictable due to environmental influence. Ten RI were identified to have a RR with no significant differences from LS97-1610 and two of them had a RR lower than resistant parent. These stable RI across environments were used for further evaluation in breeding programs. Additionally, data obtained from field evaluation can be used in combination with molecular data to study the effect of quantitative trait loci (QTL) with the environment. The identification of common QTL across environments with consistent expression is the ultimate goal of every marker-assisted selection program.
