These seven accessions could be potential sources for understanding the resistant mechanisms and can be further used in developing resistant cultivars or introgressing resistance in popular released varieties.</description><identifier>ISSN: 0929-1873</identifier><identifier>EISSN: 1573-8469</identifier><identifier>DOI: 10.1007/s10658-016-0879-9</identifier><language>eng</language><publisher>Dordrecht: Springer Netherlands</publisher><subject>Aflatoxins ; Agriculture ; Arachis hypogaea ; Aspergillus flavus ; Biomedical and Life Sciences ; Contamination ; Cultivars ; Ecology ; Harvesting ; Life Sciences ; Plant diseases ; Plant Pathology ; Plant resistance ; Plant Sciences ; Studies ; Toxins</subject><ispartof>European journal of plant pathology, 2016-08, Vol.145 (4), p.901-913</ispartof><rights>Koninklijke Nederlandse Planteziektenkundige Vereniging 2016</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c392t-d3da6940b537cbb26561c3d49384de106017a4893340a0a47743ffc26bd2a62b3</citedby><cites>FETCH-LOGICAL-c392t-d3da6940b537cbb26561c3d49384de106017a4893340a0a47743ffc26bd2a62b3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s10658-016-0879-9$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s10658-016-0879-9$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,780,784,27924,27925,41488,42557,51319</link.rule.ids></links><search><creatorcontrib>Waliyar, F.</creatorcontrib><creatorcontrib>Kumar, K.
