The defender took over leadership duties and impressed in that role as the hosts came from behind thanks to goals from Adam Le Fondre and Danny Guthrie, after former Madejski Stadium player Jay Tabb had put Town in front.
"Our previous captain Jobi McAnuff was on the bench as an impact player today so Sean got the armband," said Adkins. "We won, so he will stay in the side and keep the captain's job. Jobi has done magnificently for me and will continue to do so.
"We have got three points from a challenging fixture and I am delighted we got off to a winning start. We had to show a lot of resolve at the end."
Adkins was keen to credit Le Fondre with the equaliser despite suggestions from opposition manager Mick McCarthy that Cole Skuse or Tyrone Mings may have got the last touch.
"It was Le Fondre's goal," said Adkins. "He got to the ball first."
The Royals chief also singled out summer recruit Royston Drenthe for special praise following an eye-catching performance by the former Real Madrid and Everton player.
"I think everyone can see that our new signing Royston Drenthe is a real talent and will be an exciting player for us this season," added Atkins.
