At stud at Qvale's Green Oaks Stud Farm in Napa Valley, northeast of Golden Gate Fields, Silky Sullivan sired several winners. Mr. Payne and Son of Silky (see external links for pedigrees) were both dual-stakes winners. On August 2, 1965, Mr. Payne emulated his father's come-from-behind style with victories in the Oceanside and La Jolla Handicaps. Son of Silky won the Omaha Gold Cup and the Centennial Derby. In 1968, another of his sons, Silky's Image (owned and bred by Qvale) won the Silky Sullivan Purse. At Pickmere Stud in Cheshire, England, a stallion named Pickmere Mistral is also part of Silky Sullivan's bloodline. Silky Sullivan's daughter, Silky Starlet, foaled Tromeros by Camden Town (who sired Pickmere Pure Gold, dam of Pickmere Mistral). There is considerable Silky Sullivan blood in the American Quarter Horse. Owners of good Quarter Horses brought him some of their best mares to breed for speed.
