In a large saucepan, bring the water, apricots and sugar to a boil. Reduce heat; simmer, uncovered, for 3-5 minutes or until sugar is dissolved.
Stir in the rice, onion, parsley, butter, lemon zest, salt and pepper. Bring to a boil. Reduce heat; cover and simmer for 25-30 minutes or until liquid is absorbed and rice is tender.
Cut a deep lengthwise slit in between each bone of the pork roast (do not cut apart); stuff with rice mixture. Place fat side up on a rack in a foil-lined shallow roasting pan. Place remaining rice in a 1-qt. baking dish; cover and refrigerate.
Bake roast, uncovered, at 350° for 1 hour. Combine preserves and lemon juice; brush over roast. Bake 15-30 minutes longer or until a thermometer reads 145°, basting twice with remaining preserves mixture.
Bake additional rice for 25-30 minutes or until heated through. Let roast stand for 10 minutes before slicing.
