Resistance and Tolerance of Landrace Wheat in Fields Infested with Pratylenchus neglectus and P. thornei

Creator:: Smiley, Richard W., Gourlie, Jennifer A., Yan, Guiping, and Rhinhart, Karl E. L.
Abstract:: Pratylenchus neglectus and P. thornei reduce wheat yields in the Pacific Northwest USA. Resistant landrace cultivars have been identified using controlled environments. Field resistance and tolerance characteristics were compared over three years and two locations for four spring wheat cultivars; the susceptible cultivars Alpowa and Louise, and the resistant landraces...

Developing a Real-Time PCR Assay for Detection and Quantification of Pratylenchus neglectus in Soil

Creator:: Yan, Guiping, Smiley, Richard W., Okubara, Patricia A., Skantar, Andrea M., and Reardon, Catherine L.
Abstract:: Pratylenchus neglectus is one of the most widespread and economically important nematodes that invades plant roots and restricts wheat productivity in the Pacific Northwest. It is challenging to quantify P neglectus using microscopic methods for studies that require large-scale sampling, such as assessment of rotation crops, wheat cultivars, and other...

Detection of Dual Heterodera avenae Resistance plus Tolerance Traits in Spring Wheat

Creator:: Smiley, Richard W. and Marshall, Juliet M.
Abstract:: The cereal cyst nematode Heterodera avenae reduces wheat yield in the Pacific Northwest. Resistance and tolerance traits among spring wheat cultivars were poorly defined. Screening trials were conducted with 39 cultivars over a 2-yr period in irrigated commercial fields that were infested by H. avenae. Comparisons were made between drill...

Spring Barley Resistance and Tolerance to the Cereal Cyst Nematode Heterodera avenae

Creator:: Marshall, Juliet M. and Smiley, Richard W.
Abstract:: Heterodera avenae is a cereal cyst nematode that reduces wheat yields in the Pacific Northwest USA. Barley is also susceptible but there were no previous reports of resistance or tolerance to H. avenae in the USA. Spring barley cultivars were assayed in H. avenae-infested fields over two years. Cultivars were...

Discovery of Heterodera filipjevi in Washington and comparative virulence with H. avenae on wheat

Creator:: Smiley, Richard W. and Yan, Guiping
Abstract:: The cereal cyst nematode Heterodera avenae suppresses wheat production in the western United States. A second species of cereal cyst nematode, H. filipjevi, was identified in eastern Oregon during 2008. This paper reports the discovery of H. filipjevi–infested fields in eastern Washington, thereby extending the known distribution of H. filipjevi...

Effect of Climate on the Distribution of Fusarium spp. Causing Crown Rot of Wheat in the Pacific Northwest of the United States

Creator:: Poole, Grant J., Smiley, Richard W., Walker, Carl, Huggins, David, Rupp, Richard, Abatzoglou, John T., Garland-Campbell, Kimberly, and Paulitz, Timothy C.
Abstract:: Fusarium crown rot (FCR) is one of the most widespread root and crown diseases of wheat in the Pacific Northwest (PNW) of the United States. Our objectives were to characterize crown rot severity and distribution throughout the PNW by conducting a survey of 210 fields covering the diverse dryland wheat-producing...

Relationship Between Climatic Factors and Distribution of Pratylenchus spp. in the Dryland Wheat-Production Areas of Eastern Washington

Creator:: Kandel, Shyam L., Smiley, Richard W., Garland-Campbell, Kimberly, Elling, Axel A., Abatzoglou, John T., Huggins, David, Rupp, Richard, and Paulitz, Timothy C.
Abstract:: Field surveys were conducted by collecting soil samples to estimate nematode densities in soil from winter wheat, spring wheat, spring barley, and spring legumes (lentil, chickpea, and pea) fields during 2010 and 2011. Pratylenchus spp. were observed in 60% of sampled fields. However, nematodes were detected in nearly all of...

Species-Specific PCR Assays for Differentiating Heterodera filipjevi and H. avenae

Creator:: Yan, Guiping, Smiley, Richard W., Okubara, Patricia A., and Skantar, Andrea M.
Abstract:: Heterodera avenae and H. filipjevi are economically important cyst nematodes that restrict production of cereal crops in the Pacific Northwest United States and elsewhere in the world. Identification of these two species is critical for recommending and implementing effective management practices. Primers were designed from the internal transcribed spacer (ITS)...

Detection and Quantification of Pratylenchus thornei in DNA Extracted from Soil Using Real-Time PCR

Creator:: Yan, Guiping, Smiley, Richard W., and Okubara, Patricia A.
Abstract:: The root-lesion nematode Pratylenchus (hornet is one of the most important pests restricting productivity of wheat in the Pacific Northwest (PNW). It is laborious and difficult to use microscopy to count and identify the nematodes in soils. A SYBR Green I-based real-time polymerase chain reaction (PCR) assay was developed to...
