i buy a agri land in mahad but my name not on 7/12 till date

From your query it is clear that you have ancestral property in Pune which stands in Your fathers name which you have attached to sale deed while executing the  sale deed to purchase property in Mahad, Raigad District.

In that case the said Talathi office and circle officer have to include your name in 7/12 extract but if they are not mutating Your name in 7/12 extract in that case the only remedy is to challenge the same by filing the RTS Appeal , before Tashildar , Mahad challenging their action/order .

Or in the alternative you can apply to the Tashildar, Pune to issue a shetkari certificate by showing your all ancestral  properties in Pune and also by filing the affidavit of Your Father.
