Frankel has had his first mare scanned in foal at Juddmonte Farms' Banstead Manor Stud in Newmarket.
The mare in question is the former David Wachman-trained Chrysanthemum, a dual Group Three winner and third in the Group One Pretty Polly Stakes at the Curragh in 2011.
Frankel, who retired at the end of last season undefeated after 14 races and became the highest-rated horse in the world, has an outstanding book of mares in his first season as a stallion.
Bated Breath, also owned by Khalid Abdullah, has had his first mare tested in foal - Pretty Primo, a winning half-sister to Group One winner Wootton Bassett.
"Both horses are proving to be very professional and it is always good to get their first mare tested in foal," stud general manager Philip Mitchell told www.juddmonte.com.
