Ranji Trophy was instituted in the year 1934-35. The ongoing season of 2025-26 is the 91st season of the tournament. But in the season 2020-21, the tournament was not played due to Covid-19 outbreak. Thus the season of 2025-26 will be the 90th season.  I have laboriously culled the centuries scored in each season of the tournament. From this data I am presenting the netizens the highest individual innings by batsmen in each season with team wise break up. Request peruse the same. Stats as at the end of the third round of the ongoing 2025-26 season.
