Try like this.Kindly Modify it according to your apex controller method
<aura:component controller= "picklistvaluesController"
                implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes,force:lightningQuickAction" 
                access="global" >

	    <aura:attribute name="picklistvalues" type="string[]" />
            <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>

<lightning:select aura:id="PicklistId" label="Enter Last Class Percentage" name="percent" >
			<option value="" text="- None -" /> 
            <aura:iteration items="{!v.picklistvalues}" var="pickval">
            	<option value="{!pickval}" text="{!pickval}" />  
        	</aura:iteration>
    	</lightning:select>
</aura:component>

js controller

({
    doInit : function(component, event, helper) {
        var action = component.get("c.getPicklistvalues");
        action.setCallback(this, function(response) {
            var Values = response.getReturnValue();
            component.set("v.picklistvalues", values);

        });
        $A.enqueueAction(action);
