To avail exemption under section 54EC the bonds must be purchased in the name of person claiming exemption for long term capital gains. However the bonds can be purchased in the joint names of your father and yourself, your father is first applicant/holder and claim exemption u/s 54EC.The bonds will be redeemed at the end of three years and tax free. On such redemption your father can gift the money to you which is tax free gift. However interest on bonds is taxable as income under income tax act in the year of accrual.
He can give capital gains as tax free gift, but he will have to pay capital gain tax on the long term gains derived by him. It is true that gift by parents are tax free.
