TBA chief executive Tom Reilly said everybody who knew Basil would be mourning his loss.
"On behalf of the directors and staff of TBA we extend our deepest sympathies to the Nolan family.
"Basil was one of the industry's true gentleman. Not only was he a great horseman but, more importantly, he was a warm and generous man who always seemed to have a smile on his face.
"He was also a devoted father of four and it was always a highlight to have a chat to Basil and his children when Raheen had a draft to sell.
"I'm sure anyone who had dealings with Basil will be grieving his loss and that the whole breeding and racing community will be thinking of the Nolan family at this difficult time."
