Chawrasia, who represented India at the Rio Olympics earlier this month, got a late spot in the event following the withdrawal of Paraguay's Fabrizio Zanotti.
The 38-year-old Chawrasia, a winner of four international events, including three on the European Tour, picked 22-year-old Chikkarangappa as his partner, who is a winner of two events on the Asian Development Tour (ADT).
Interestingly, both Chawrasia (world rank 234) and Chikkarangappa (world rank 439), will be making their debut at the World Cup. India will be one among seven Asian nations that will make up the elite 28-team field in Melbourne.
"I picked Chikkarangappa as my partner as he is one of the most promising young talents in India and is in good form and high on confidence at the moment."
Chawrasia had participated at another major team event earlier this year when he represented Team Asia at the EurAsia Cup.
An elated Chikkarangappa said, "I am honoured that SSP has picked me as a partner for the World Cup. When Anirban played at the World Cup last time, I saw it on TV and started dreaming about representing my country in such a prestigious tournament. Now the time has come for me to represent India and I would do my best to make my country proud."
