How to show the parent site link, like home in breadcrumb in sharepoint 2013 when i am in sub site?
You can see here, is a possible solution for you. Replace this:
<SharePoint:SPLinkButton runat="server" NavigateUrl="~site/" id="onetidProjectPropertyTitle"><SharePoint:ProjectProperty Property="Title" runat="server" /></SharePoint:SPLinkButton>

<asp:SiteMapPath

RenderCurrentNodeAsLink="false"
NodeStyle-CssClass="breadcrumbNode"
CurrentNodeStyle-CssClass="breadcrumbCurrentNode"
