Hello Srikanat,

You need to query on existing records on controller side, describe picklist values & populate picklist values those records are not created in your_option variable. 
<apex:selectList id="selectedObject" value="{!your_variable}">
	<apex:selectOptions value="{!your_options}"/>
</apex:selectList>
