On the sidelines of the send-off ceremony for the CWG-bound athletes, IOA acting president Anil Khanna called it a 'gender-neutral contingent' with 108 men and 107 women being part of the touring party.
The overall contingent count stands at 322 including 72 team officials, 26 extra officials, nine contingent staff, including three general managers.
Discipline-wise, the biggest contingent is of athletics and hockey (36 entries each).
India will also take part in women's cricket, which is making its CWG debut, aquatics, badminton, table tennis, boxing, cycling, gymnastics, triathlon, wrestling, weightlifting, lawn bowls, squash, judo and para sports.
India has only won 28 medals in athletics in CWG history but world championship medal-winning long jumper Anju Bobby George is expecting a rich haul of at least seven medals this time with Neeraj Chopra expected to win gold in javelin.
Chopra is also likely to be India's flag-bearer at the opening ceremony.
"We have about 13 athletes who could be in the medals bracket for second and third position but we are expecting seven medals at least across javelin, long jump, triple jump and discus," she said.
Rajesh Bhandari appointed chef de mission after Onkar Singh's withdrawal
Onkar Singh was Indian Olympic Association's first choice for the chef de mission role but he requested the acting president Anil Khanna to consider someone else as he is not ready to take up the responsibility due to health issues.
