Ultimately, Secretariat officially sired 663 named foals, including 341 winners (51.4%) and 54 stakes winners (8.1%). There has been some criticism of Secretariat as a stallion, mainly because he did not produce male offspring of his own ability and did not leave a leading sire son behind, but his legacy is assured through the quality of his daughters, several of whom were excellent racers and even more of whom were excellent producers. In 1992, Secretariat was the leading broodmare sire in North America. Overall, Secretariat's daughters produced 24 Grade/Group 1 winners. As a broodmare sire, Secretariat's most notable progeny were: Weekend Surprise, a stakes winner and the 1992 Kentucky Broodmare of the Year. Her sons include 1990 Preakness winner Summer Squall and 1992 Horse of the Year A.P. Indy. Terlingua, a stakes winner and dam of leading sire Storm Cat. Secrettame, a stakes winner and dam of important sire Gone West, whose descendants include Kentucky Derby and Preakness Stakes winner Smarty Jones. Six Crowns, dam of champion two-year-old and sire Chief's Crown. Sister Dot, dam of champion two-year-old and sire Dehere. Celtic Assembly, dam of Volksraad, leading sire in New Zealand. Betty's Secret, dam of Secreto, winner of The Derby, and Istabraq, three-time winner of the Champion Hurdle.
