What can be done if a gift deed is revoked

My uncle has registered an agricultural land property of in the form of gift deed in 2004 to my father. In 2006 he unilaterally revoked the gift deed and did not even inform us of the revocation. Is the revocation of gift deed legal and valid even without my father's consent. My father died in 2009 and i was a minor during the time of his death. The property is still in my pattadar pass book which were changed into my name after my father's death. I want to sell the property now. Will there be any problem during the registration due to the document regarding revocation of the gift deed? Please advise on further action to be taken.
