ボールドルーラー
Secretariat was officially bred by Christopher Chenery's Meadow Stud, but the breeding was actually arranged by Penny Chenery (then known as Penny Tweedy), who had taken over the running of the stable in 1968 when her father became ill. Secretariat was sired by Bold Ruler and his dam was Somethingroyal, a daughter of Princequillo. Bold Ruler was the leading sire in North America from 1963 to 1969 and again in 1973. Owned by the Phipps family, Bold Ruler possessed both speed and stamina, having won the Preakness Stakes and Horse of the Year honors in 1957, and American Champion Sprint Horse honors in 1958. Bold Ruler was retired to stud at Claiborne Farm, but the Phippses owned most of the mares to which Bold Ruler was bred, and few of his offspring were sold at public auction.
