Ante-post favourite Rhododendron tops 18 fillies confirmed for the Group 1 Qipco 1000 Guineas at Newmarket on Sunday.

Last year's Fillies' Mile winner heads a five-strong team for trainer Aidan O'Brien, who is aiming for a fourth win in the Classic over the Rowley Mile. The Ballydoyle maestro, who claimed the race 12 months ago with Minding, has also left in Hydrangea, Rain Goddess, Roly Poly and Winter.
