QTL mapping of Phytophthora root rot resistance and aphid resistance in soybean
… stresses such as soybean cyst nematode (SCN), Phytophthora root rot (PRR), sudden death syndromes (SDS) and soybean aphids are threatening soybean production and plant health. Three independent projects were performed to identify genetic resistance against PRR, caused by Phytophthora sojae; to …

Evaluation of Soil Compaction, Plant Density, and Resistance to Phytophthora Root Rot in Soybeans
Phytophthora root rot, caused by Phytophthora megasperma f. sp. glycinea Kuan and Erwin, is a soil-borne fungal disease of soybean Glycine max (L.) Merr. . Studies were conducted to determine the effects of soil compaction on phytophthora incidence, to determine if reduced soybean stand due to …

Using targeted phenomics and environmental proxies to understand Phytophthora medicaginis and Phytophthora root rot resistance in Australian chickpea
Australian chickpea production is constrained by Phytophthora root rot (PRR), caused by the soil-borne oomycete Phytophthora medicaginis. Yield penalties are exacerbated by waterlogging resulting in partial or complete crop losses with few control options. Higher levels of PRR resistance have been …

Agronomic and molecular marker mapping of brown stem rot, phytophthora root rot, and powdery mildew resistance in soybean
… of soybean (Glycine max (L.) Merr.). Brown stem rot of soybean, caused by Phialophora gregata (Allington and Chamberlain) W. Gams, and phytophthora root rot, caused by Phytophthora sojae Kaufmann & Gerdemann, are major diseases of soybean in Illinois. A gene for resistance to powdery mildew, …

Evaluation of fertile lines derived from the hybridization of Glycine max and G. tomentella
… evaluation of plant height, maturity, and seed protein and oil concentration, confirm introgression of G. tomentella genes. Genotypic data obtained using a custom single-nucleotide polymorphism (SNP) GoldenGate array also showed introgression of G. tomentella genes across most G. max chromosomes. …

Biological control studies of Phytophthora Parasitica root rot of boxwood using multiple antagonists
Phytophthora parasitica is an important root rot pathogen of American and English boxwood, Buxus sempervirens and B. sempervirens var. suffruticosa, respectively, shrubs used extensively in the landscape in Virginia and North Carolina. Studies were undertaken to screen microorganisms for antagonism …

Analyses of the in vitro effects of phosphite on Phytophthora cinnamomi isolates
Phytophthora Root Rot, caused by the oomycete Phytophthora cinnamomi (Rands), results in devastating decreases in avocado yields every year. Successful management of P. cinnamomi relies on many features, one of which is chemical control by phosphite. Despite its continuous use in South Africa for …

Restriction fragment length polymorphism mapping of quantitative and qualitative traits in soybean
… quantitative trait loci (QTL) for seed size, protein and oil content and for the content of the fatty acids palmitate, stearate, oleate, linoleate and linolenate were mapped. The traits were measured on seed harvested from a replicated trial of 60 F[subscript]2-derived lines from a cross …

Phytophthora Sojae Infecting Soybean: Pathotype Diversity, New Sources of Resistance and Interaction with the Soybean Cyst Nematode
<p>Phytophthora root and stem rot, caused by <em>Phytophthora sojae</em> Kaufmann and Gerdemann, is an important disease of soybean (<em>Glycine max</em> L.) in South Dakota. To gain a better understanding of the importance of P. sojae in South Dakota, specifically pathotype diversity, …
