P. sojae; Pythium and Fusarium. Continue the VIGs experiments for potential R-gene sequence and candidate genes for resistance via functional analysis. Continue to use SNP markers for the Illumina 6KSNP chip for high throughput analysis of additional populations segregating for novel Rps genes and QTL. Collect soil from studies of soil factors that influence SDS. Harvest plots and analyze summer data. Complete identification of pathogens from summer/fall surveys. Submit 2 to 3 manuscripts. Continue to evaluate segregating populations for resistance to key Pythium spp.
Second quarter (March 2019): Complete screening of all Ohio Breeders material; screening of populations with novel resistance developed/advanced during summer of 2014 as well as isolate DNA for marker analysis. In addition to Phytophthora sojae, screen populations for resistance to Py. irregulare, Py ultimum and compare responses across isolates. Provide breeders with any new data to facilitate decisions required for new soybean populations. Continue with experiments for functional analysis of candidate genes.
Third quarter (June 2019): Initiate summer field studies for disease management, begin to increase germplasm with novel resistance genes that require further analysis, evaluate yield effects for specific QTL, increase selected germplasm for studies. Monitor disease development throughout the state, collect isolates for further studies.
Fourth quarter (September 2019) – Collect and summarize summer field data, continue screening and fine mapping of resistance genes; begin writing reports; present results at APS meeting to be held in Cleveland!
