<p>Soybean aphid (<em>Aphis glycines</em> Matsumura; SA) is a major invasive pest of soybean [<em>Glycine max</em> (L.) Merr.] in northern production regions of North America. Although insecticides are currently the main method for controlling this pest, SA-resistant cultivars are being developed to sustainably manage SA in the future. The viability of SA-resistant cultivars may depend on identifying a diverse set of resistance genes from screening various germplasm sources, including wild soybean (<em>Glycine soja</em> Siebold and Zucc.), the progenitor of cultivated soybean. Data consisted of infestation ratings generated for a total of 337 distinct plant introduction lines of wild soybean that were exposed to avirulent SA biotype 1 for 14 d in 25 separate tests. Individual plants of the test lines were given a common rating by two researchers, based on a rating scale that progressed from 1=0 to 50, 2=51 to 100, 3=101 to 150, 4=151 to 200, 5=201 to 250, and 6 with >250 SA per test plant. Public dissemination of this dataset will allow for further analyses and evaluation of resistance among the test lines. </p><div><br>Resources in this dataset:</div><br><ul><li><p>Resource Title: Infestation ratings for individual plants of various wild soybean lines.</p> <p>File Name: Web Page, url: <a href="https://ars.els-cdn.com/content/image/1-s2.0-S2352340917304432-mmc2.xlsx">https://ars.els-cdn.com/content/image/1-s2.0-S2352340917304432-mmc2.xlsx</a> </p><p>MS Excel spreadsheet showing infestation ratings for individual plants of 337 distinct plant introduction (PI) wild soybean lines following 14 d of exposure to SA.</p><p>Resource Software Recommended: Microsoft Excel,url: <a href="https://office.microsoft.com/excel/">https://office.microsoft.com/excel/</a> </p></li></ul><p></p>
Support analysis and evaluation of host-plant resistance among the wild soybean lines subjected to infestation by soybean aphids. Useful in identifying plant introduction (PI) lines of wild soybean with putative resistance to soybean aphid (SA). Provides baseline dataset with avirulent SA biotype 1 that can be compared in future tests against virulent SA biotypes. Useful in deciding what PI lines to include in follow-up resistance tests with SA. Provides phenotypic data that can be used in studies that genetically characterize the basis of resistance in soybean.
