Jockey William Buick settled the daughter of Kyllachy at the rear of the field where she switched off nicely.
On entering the final three furlongs it looked as if she had a mountain to climb as there was still a wall of horses ahead and Buick was hard at work on board.
However, Kyleene responded well to this pressure and picked up strongly inside the final furlong to grab the leaders late on, winning by a head.
