The dam of Beau Genius was Royal Colleen, a daughter of Northern Dancer's son, 1968 Canadian Horse of the Year, Viceregal.
Competing at age five, Beau Genius had the best year of his racing career, winning on both fast and sloppy track surfaces.
He won nine stakes races in 1990, beginning in January when Bill Shoemaker rode him to victory in the Hallandale Handicap at Gulfstream Park.
There, he notably sired Belle Genius who won the Group One Moyglare Stud Stakes at the Curragh in Ireland.
He sired thirty-two stakes race winners and from 1999 he stood at Donald and Karen Cohn's Ballena Vista Farm in Ramona, California.
