Tax on FDR

Sir/Madam , I invest a lump sum money in FDR in the name of my minor son u/g of myself. At the time of maturity he become major.
Now my question is that from time of maturity interest income and sum belongs to me or my son for tax
purpose?
Secondly can I take all interest income in the year of maturity of FDR as it is paid after accumulation of previous years at the end of time ?
Thanks for opinion.
