I have added a custom tab in admin Products Edit section
http://i.prntscr.com/b78b12c41b3546ba8bd9d657dabcef98.png
The values in the select field are values from my custom tables. I have saved corresponding id of the label and product id to my custom table. I have used the following method for this.

Created the observer’s class in app/code/Vendor/Module/Observer/CatalogProductSavelabelAfterObserver.php:
<?php
namespace Vendor\Module\Observer;
use \Magento\Framework\Event\ObserverInterface;
use \Magento\Framework\Event\Observer as EventObserver;

class CatalogProductSavelabelAfterObserver implements ObserverInterface

}
/**

public function execute(\Magento\Framework\Event\Observer $observer)
{
/** @var \Magento\Catalog\Model\Product $product */
$product = $observer->getEvent()->getProduct();
if (!$product) {
return;
}
$productId = $observer->getProduct()->getId();
$id = $product->getData(CustomFieldset::FIELD_NAME_SELECT);
if($id == 'none'){
$productCollection = $this->productgridModel->load($productId,'product_id');
$productCollection->delete();
}
$this->productgridModel->setData('label_id',$id);
$this->productgridModel->setData('product_id',$productId);
$this->productgridModel->save();
$this->productgridModel->unsetData();
}
}
But on editing the same product,the values are not displayed as selected. Hence it is pointing to the first value in the drop down ie,'None'. Please help .
