Why is the ID showing null in my System.assertEquals() statement?

In my test class, I am simply updating a list of custom object records (QA Release) and then I want to compare the field value of these newly inserted records in the list to the field values of Account object. I get the following error:
System.AssertException: Assertion Failed: Expected: Version0, Actual: null

The line which is causing this exception:
System.assertEquals(qaRels[i].Release_Version__c, accs[i].Production_Version__c);

To me, it seems like the accs[i].Production_Version__c is getting populated but the qaRels[i].Release_Version__c is returning Null even when it does have a value. 

Here is the code snippet. Can anyone please throw light on why the System.assert statement is failing?
for (Integer i=0; i<225; i++) {
     QA_Release__c qaRel  = new QA_Release__c();
     qaRel.Client__c             = accs[i].Id;
     qaRel.Objective__c          = 'New Build';
     qaRel.Due_Date__c           =;
     qaRel.Client_Site_Type__c   = 'Production';
     insert qaRels;
     //This trick gives us a new set of Governor Limits
     // Test1: Update QA Releases and fill out the delivered date (200+ records)
        for(Integer i=0; i<225; i++) {
        qaRels[i].Delivered_Date__c  =;
        qaRels[i].Release_Version__c = 'Version' + i;
        update qaRels;
      qaRels =[SELECT Id,Release_Version__c FROM QA_Release__c];
        //Principle #2: Assert your results
     List<String> storeRelVer = new List<String>();
     for(Integer i=0; i<225; i++) {
     System.assertEquals(qaRels[i].Release_Version__c, accs[i].Production_Version__c);

System.asswerEquals is coming with expected value as "Version0" it means value is set fo this so can you please check acc list because acc[i].Production_version__c is coming null.
