Public Provident Fund

Friends

I have a PPF account wherein I yearly deposit the maximum prescribed amount i.e Rs ONE LAKH. I want to open PPF account ┬áin the name my son (10yrs) as a guardian. I would like to know whether I can deposit another one lakh rupees yearly in my son’s PPF in addition to one lakh rupees that I deposit in my PPF . However,I shall claim Income tax benefit (80C) only on one lakh rupees deposited in my account.
