List<Schema.RecordTypeInfo> recordTypeInfoList = Account.SObjectType.getDescribe().getRecordTypeInfos();
List<SelectOption> recordTypes = new List<SelectOption>();
for(RecordTypeInfo info: recordTypeInfoList) {
    //Check record type is available for current user profile
    if(info.isAvailable()) {
        if(info.getName() != 'Master' && info.getName().trim() != ''){
            recordTypes.add(new SelectOption(info.getRecordTypeId(), info.getName()));
        }
    }
