Figure 4From: Identification of QTLs associated with oil content and mapping FAD2 genes and their relative contribution to oil quality in peanut (Arachis hypogaeaL.)Epistatic interaction identified by QTL Network for oil quality traits. Figure shows epistatic interaction for (a) oil content, (b) oleic acid, (c) linoleic acid, and (d) oleic/linoleic (O/L) ratio. The black ball represents epistatic QTLs without individual effect; the blue ball represents additive × (additive × environment) interaction; the red ball indicates epistatic QTLs with direct individual effect while interacting loci are shown by red colored bars.Back to article page
